<s>[INST] What is the outlook for Peripheral Neuropathy ? [/INST] In acute neuropathies, such as Guillain-Barr syndrome, symptoms appear suddenly, progress rapidly, and resolve slowly as damaged nerves heal. In chronic forms, symptoms begin subtly and progress slowly. Some people may have periods of relief followed by relapse. Others may reach a plateau stage where symptoms stay the same for many months or years. Some chronic neuropathies worsen over time, but very few forms prove fatal unless complicated by other diseases. Occasionally the neuropathy is a symptom of another disorder. </s>

<s>[INST] what research (or clinical trials) is being done for Peripheral Neuropathy ? [/INST] The National Institute of Neurological Disorders and Stroke (NINDS) and other institutes of the National Institutes of Health (NIH) conduct research related to peripheral neuropathies in laboratories at the NIH and also support additional research through grants to major medical institutions across the country. Current research projects funded by the NINDS involve investigations of genetic factors associated with hereditary neuropathies, studies of biological mechanisms involved in diabetes-associated neuropathies, and investigations exploring how the immune system contributes to peripheral nerve damage. Neuropathic pain is a primary target of NINDS-sponsored studies aimed at developing more effective therapies for symptoms of peripheral neuropathy. Some scientists hope to identify substances that will block the brain chemicals that generate pain signals, while others are investigating the pathways by which pain signals reach the brain. </s>

<s>[INST] What is (are) Microcephaly ? [/INST] Microcephaly is a medical condition in which the circumference of the head is smaller than normal because the brain has not developed properly or has stopped growing. Microcephaly can be present at birth or it may develop in the first few years of life. It is most often caused by genetic abnormalities that interfere with the growth of the cerebral cortex during the early months of fetal development. Babies may also be born with microcephaly if, during pregnancy, their mother abused drugs or alcohol; became infected with a cytomegalovirus, rubella (German measles), varicella (chicken pox) virus, or possibly Zika virus; was exposed to certain toxic chemicals; or had untreated phenylketonuria (PKU, a harmful buildup of the amino acid phenylalanine in the blood). Microcephaly is associated with Downs syndrome, chromosomal syndromes, and neurometabolic syndromes. With viral-induced brain injury, such as with the Zika virus, there is often widespread tissue and cell death leading to brain shrinkage rather than simply impaired growth. The Zika virus is also associated with retinal lesions in about a third of cases, often leading to blindness. Depending on the severity of the accompanying syndrome, children with microcephaly may have impaired cognitive development, delayed motor functions and speech, facial distortions, dwarfism or short stature, hyperactivity, seizures, difficulties with coordination and balance, and other brain or neurological abnormalities. </s>

<s>[INST] What are the treatments for Microcephaly ? [/INST] There is no treatment for microcephaly that can return a childs head to a normal size or shape. Treatment focuses on ways to decrease the impact of the associated deformities and neurological disabilities. Children with microcephaly and developmental delays are usually evaluated by a pediatric neurologist and followed by a medical management team. Early childhood intervention programs that involve physical, speech, and occupational therapists help to maximize abilities and minimize dysfunction. Medications are often used to control seizures, hyperactivity, and neuromuscular symptoms. Genetic counseling may help families understand the risk for microcephaly in subsequent pregnancies. </s>

<s>[INST] What is the outlook for Microcephaly ? [/INST] Some children with microcephaly will have normal intelligence and a head that will grow bigger, but they may track below the normal growth curves for head circumference. Some children may have only mild disability, while those with more severe cases may face significant learning disabilities, cognitive delays, or develop other neurological disorders. Many, if not most, cases if Zika microcephaly will be very severe, possibly requiring lifelong intensive care. </s>

<s>[INST] what research (or clinical trials) is being done for Microcephaly ? [/INST] The National Institute of Neurological Disorders and Stroke (NINDS), one of several institutes of the National Institutes of Health (NIH), conducts and funds research aimed at understanding normal brain development, as well as disease-related disorders of the brain and nervous system. Other NIH institutes and centers also support research on disorders that may affect development. Among several projects, scientists are studying genetic mechanisms and identifying novel genes involved with brain development. Animal models are helping scientists to better understand the pathology of human disease, and to discover how the sizes of tissues and organs are impacted by developmental variability. Other researchers hope to gain a better understanding of normal brain development and the molecular and cellular mechanisms of microcephaly. </s>

<s>[INST] What is (are) Erb-Duchenne and Dejerine-Klumpke Palsies ? [/INST] The brachial plexus is a network of nerves that conducts signals from the spine to the shoulder, arm, and hand. Brachial plexus injuries are caused by damage to those nerves. Erb-Duchenne (Erb's) palsy refers to paralysis of the upper brachial plexus. Dejerine-Klumpke (Klumpke's) palsy refers to paralysis of the lower brachial plexus. Although injuries can occur at any time, many brachial plexus injuries happen when a baby's shoulders become impacted during delivery and the brachial plexus nerves stretch or tear. There are four types of brachial plexus injuries: avulsion, the most severe type, in which the nerve is torn from the spine; rupture, in which the nerve is torn but not at the spinal attachment; neuroma, in which the nerve has torn and healed but scar tissue puts pressure on the injured nerve and prevents it from conducting signals to the muscles; and neuropraxia or stretch, in which the nerve has been damaged but not torn. Neuropraxia is the most common type of brachial plexus injury. Symptoms of brachial plexus injury may include a limp or paralyzed arm; lack of muscle control in the arm, hand, or wrist; and lack of feeling or sensation in the arm or hand. </s>

<s>[INST] What are the treatments for Erb-Duchenne and Dejerine-Klumpke Palsies ? [/INST] Some brachial plexus injuries may heal without treatment. Many children who are injured during birth improve or recover by 3 to 4 months of age. Treatment for brachial plexus injuries includes physical therapy and, in some cases, surgery. </s>

<s>[INST] What is the outlook for Erb-Duchenne and Dejerine-Klumpke Palsies ? [/INST] The site and type of brachial plexus injury determines the prognosis. For avulsion and rupture injuries, there is no potential for recovery unless surgical reconnection is made in a timely manner. The potential for recovery varies for neuroma and neuropraxia injuries. Most individuals with neuropraxia injuries recover spontaneously with a 90-100 percent return of function. </s>

<s>[INST] what research (or clinical trials) is being done for Erb-Duchenne and Dejerine-Klumpke Palsies ? [/INST] The NINDS conducts and supports research on injuries to the nervous system such as brachial plexus injuries. Much of this research is aimed at finding ways to prevent and treat these disorders. </s>

<s>[INST] What is (are) Dementia With Lewy Bodies ? [/INST] Dementia with Lewy bodies (DLB) is one of the most common types of progressive dementia. The central features of DLB include progressive cognitive decline, fluctuations in alertness and attention, visual hallucinations, and parkinsonian motor symptoms, such as slowness of movement, difficulty walking, or rigidity. People may also suffer from depression. The symptoms of DLB are caused by the build-up of Lewy bodies accumulated bits of alpha-synuclein protein -- inside the nuclei of neurons in areas of the brain that control particular aspects of memory and motor control. Researchers dont know exactly why alpha-synuclein accumulates into Lewy bodies or how Lewy bodies cause the symptoms of DLB, but they do know that alpha-synuclein accumulation is also linked to Parkinson's disease, multiple system atrophy, and several other disorders, which are referred to as the "synucleinopathies." The similarity of symptoms between DLB and Parkinsons disease, and between DLB and Alzheimers disease, can often make it difficult for a doctor to make a definitive diagnosis. In addition, Lewy bodies are often also found in the brains of people with Parkinson's and Alzheimers diseases. These findings suggest that either DLB is related to these other causes of dementia or that an individual can have both diseases at the same time. DLB usually occurs sporadically, in people with no known family history of the disease. However, rare familial cases have occasionally been reported. </s>

<s>[INST] What are the treatments for Dementia With Lewy Bodies ? [/INST] There is no cure for DLB. Treatments are aimed at controlling the cognitive, psychiatric, and motor symptoms of the disorder. Acetylcholinesterase inhibitors, such as donepezil and rivastigmine, are primarily used to treat the cognitive symptoms of DLB, but they may also be of some benefit in reducing the psychiatric and motor symptoms. Doctors tend to avoid prescribing antipsychotics for hallucinatory symptoms of DLB because of the risk that neuroleptic sensitivity could worsen the motor symptoms. Some individuals with DLB may benefit from the use of levodopa for their rigidity and loss of spontaneous movement. </s>

<s>[INST] What is the outlook for Dementia With Lewy Bodies ? [/INST] Like Alzheimers disease and Parkinsons disease, DLB is a neurodegenerative disorder that results in progressive intellectual and functional deterioration. There are no known therapies to stop or slow the progression of DLB. Average survival after the time of diagnosis is similar to that in Alzheimers disease, about 8 years, with progressively increasing disability. </s>

<s>[INST] what research (or clinical trials) is being done for Dementia With Lewy Bodies ? [/INST] The National Institute of Neurological Disorders and Stroke (NINDS) and other institutes of the National Institutes of Health conduct research related to DLB in laboratories at the NIH and support additional research through grants to major medical institutions across the country. Much of this research focuses on searching for the genetic roots of DLB, exploring the molecular mechanisms of alpha-synuclein accumulation, and discovering how Lewy bodies cause the particular symptoms of DLB and the other synucleinopathies. The goal of NINDS research is to find better ways to prevent, treat, and ultimately cure disorders such as DLB. </s>

<s>[INST] What is (are) Encephalitis Lethargica ? [/INST] Encephalitis lethargica is a disease characterized by high fever, headache, double vision, delayed physical and mental response, and lethargy. In acute cases, patients may enter coma. Patients may also experience abnormal eye movements, upper body weakness, muscular pains, tremors, neck rigidity, and behavioral changes including psychosis. The cause of encephalitis lethargica is unknown. Between 1917 to 1928, an epidemic of encephalitis lethargica spread throughout the world, but no recurrence of the epidemic has since been reported. Postencephalitic Parkinson's disease may develop after a bout of encephalitis-sometimes as long as a year after the illness. </s>

<s>[INST] What are the treatments for Encephalitis Lethargica ? [/INST] Treatment for encephalitis lethargica is symptomatic. Levodopa and other antiparkinson drugs often produce dramatic responses. </s>

<s>[INST] What is the outlook for Encephalitis Lethargica ? [/INST] The course of encephalitis lethargica varies depending upon complications or accompanying disorders. </s>

<s>[INST] what research (or clinical trials) is being done for Encephalitis Lethargica ? [/INST] The NINDS supports research on disorders that affect the brain, such as encephalitis lethargica, with the goal of finding ways to prevent and treat them. (The disease was the subject of the book and film, "Awakenings.") </s>

<s>[INST] What is (are) Cephalic Disorders ? [/INST] Cephalic disorders are congenital conditions that stem from damage to or abnormal development of the budding nervous system. Most cephalic disorders are caused by a disturbance that occurs very early in the development of the fetal nervous system. Damage to the developing nervous system is a major cause of chronic, disabling disorders, and sometimes death in infants, children, and even adults. Cephalic disorders may be influenced by hereditary or genetic conditions or by environmental exposures during pregnancy (e.g., medication taken by the mother, maternal infection, exposure to radiation). Some cephalic disorders occur when the cranial sutures (the fibrous joints that connect the bones of the skull) join prematurely. Understanding the normal development of the human nervous system may lead to a better understanding of cephalic disorders. </s>

<s>[INST] What are the treatments for Cephalic Disorders ? [/INST] Treatments for cephalic disorders depend upon the particular type of disorder. For most cephalic disorders, treatment is only symptomatic and supportive. In some cases, anticonvulsant medications shunts, or physical therapy are appropriate. </s>

<s>[INST] What is the outlook for Cephalic Disorders ? [/INST] The degree to which damage to the developing nervous system harms the mind and body varies enormously. Many disabilities are mild enough to allow those afflicted to eventually function independently in society. Others are not. Some infants, children, and adults die; others remain totally disabled; and an even larger population is partially disabled, functioning well below normal capacity. </s>

<s>[INST] what research (or clinical trials) is being done for Cephalic Disorders ? [/INST] Scientists are rapidly learning how harmful insults, a critical nutritional deficiency, or exposure to an environmental insult at various stages of pregnancy can lead to developmental disorders. Research projects currently underway include a study to evaluate increased risk of neural tube defects and various other congenital malformations in association with environmental and occupational exposure to pesticides. Scientists are also concentrating their efforts on understanding the complex processes responsible for normal early development of the brain and nervous system and how the disruption of any of these processes results in congenital anomalies such as cephalic disorders. Currently, researchers are examining the mechanisms involved in neurulation -- the process of forming the neural tube. Investigators are also conducting a variety of genetic studies. Understanding how genes control brain cell migration, proliferation, differentiation, and death, and how radiation, drugs, toxins, infections, and other factors disrupt these processes will aid in preventing many congenital neurological disorders. Recent studies have shown that the addition of folic acid to the diet of women of child-bearing age may significantly reduce the incidence of neural tube defects. Therefore, it is recommended that all women of child-bearing age consume 0.4 mg of folic acid daily. </s>

<s>[INST] What is (are) Multi-Infarct Dementia ? [/INST] Multi-infarct dementia (MID) is a common cause of memory loss in the elderly. MID is caused by multiple strokes (disruption of blood flow to the brain). Disruption of blood flow leads to damaged brain tissue. Some of these strokes may occur without noticeable clinical symptoms. Doctors refer to these as silent strokes. An individual having asilent stroke may not even know it is happening, but over time, as more areas of the brain are damaged and more small blood vessels are blocked, the symptoms of MID begin to appear. MID can be diagnosed by an MRI or CT of the brain, along with a neurological examination. Symptoms include confusion or problems with short-term memory; wandering, or getting lost in familiar places; walking with rapid, shuffling steps; losing bladder or bowel control; laughing or crying inappropriately; having difficulty following instructions; and having problems counting money and making monetary transactions. MID, which typically begins between the ages of 60 and 75, affects men more often than women. Because the symptoms of MID are so similar to Alzheimers disease, it can be difficult for a doctor to make a firm diagnosis. Since the diseases often occur together, making a single diagnosis of one or the other is even more problematic. </s>

<s>[INST] What are the treatments for Multi-Infarct Dementia ? [/INST] There is no treatment available to reverse brain damage that has been caused by a stroke. Treatment focuses on preventing future strokes by controlling or avoiding the diseases and medical conditions that put people at high risk for stroke: high blood pressure, diabetes, high cholesterol, and cardiovascular disease. The best treatment for MID is prevention early in life eating a healthy diet, exercising, not smoking, moderately using alcohol, and maintaining a healthy weight. </s>

<s>[INST] What is the outlook for Multi-Infarct Dementia ? [/INST] The prognosis for individuals with MID is generally poor. The symptoms of the disorder may begin suddenly, often in a step-wise pattern after each small stroke. Some people with MID may even appear to improve for short periods of time, then decline after having more silent strokes. The disorder generally takes a downward course with intermittent periods of rapid deterioration. Death may occur from stroke, heart disease, pneumonia, or other infection. </s>

<s>[INST] what research (or clinical trials) is being done for Multi-Infarct Dementia ? [/INST] The National Institute of Neurological Disorders and Stroke (NINDS) conducts research related to MID in its laboratories at the National Institutes of Health (NIH), and also supports additional research through grants to major medical institutions across the country. Much of this research focuses on finding better ways to prevent, treat, and ultimately cure the vascular dementias, such as MID. </s>

<s>[INST] What is (are) Febrile Seizures ? [/INST] Febrile seizures are convulsions or seizures in infants or small children that are brought on by a fever. Most often during a febrile seizure, a child loses consciousness and shakes uncontrollably. Less commonly, a child becomes rigid or has twitches in only a portion of the body. Most febrile seizures last a minute or two; some can be as brief as a few seconds, while others may last for more than 15 minutes. Approximately one in every 25 children will have at least one febrile seizure. Febrile seizures usually occur in children between the ages of 6 months and 5 years, with the risk peaking in the second year of life. The older a child is when the first febrile seizure occurs, the less likely that child is to have more. A few factors appear to boost a child's risk of having recurrent febrile seizures, including young age (less than 18 months) during the first seizures and having immediate family members with a history of febrile seizures. </s>

<s>[INST] What are the treatments for Febrile Seizures ? [/INST] A child who has a febrile seizure usually doesn't need to be hospitalized. If the seizure is prolonged or is accompanied by a serious infection, or if the source of the infection cannot be determined, a doctor may recommend that the child be hospitalized for observation. Prolonged daily use of anti-seizure medicines is usually not recommended because of their potential for harmful side effects. Children especially prone to febrile seizures may be treated with medication when they have a fever to lower the risk of having another febrile seizure. </s>

<s>[INST] What is the outlook for Febrile Seizures ? [/INST] The vast majority of febrile seizures are short and harmless. There is no evidence that short febrile seizures cause brain damage. Multiple or prolonged seizures are a risk factor for epilepsy but most children who experience febrile seizures do not go on to develop the reoccurring seizures that re characteristic of epilepsy. Certain children who have febrile seizures face an increased risk of developing epilepsy. These children include those who have a febrile seizure that lasts longer than 10 minutes, who have febrile seizures that are lengthy or affect only one part of the body, or experience seizures that reoccur within 24 hours.. </s>

<s>[INST] what research (or clinical trials) is being done for Febrile Seizures ? [/INST] The National Institute of Neurological Disorders and Stroke (NINDS) conducts research on seizures at its research center in Bethesda, Maryland, and through grants to major medical institutions across the country. NINDS-supported scientists are exploring environmental, biological, and genetic risk factors that might make children susceptible to febrile seizures. Investigators continue to monitor the long-term impact that febrile seizures might have on intelligence, behavior, school achievement, and the development of epilepsy. Investigators also continue to explore which drugs can effectively treat or prevent febrile seizures, and to identify factors that may cause a child who has prolonged febrile seizures to develop temporal lobe epilepsy. </s>

<s>[INST] What is (are) Normal Pressure Hydrocephalus ? [/INST] Normal pressure hydrocephalus (NPH) is an abnormal buildup of cerebrospinal fluid (CSF) in the brain's ventricles, or cavities. It occurs if the normal flow of CSF throughout the brain and spinal cord is blocked in some way. This causes the ventricles to enlarge, putting pressure on the brain. Normal pressure hydrocephalus can occur in people of any age, but it is most common in the elderly. It may result from a subarachnoid hemorrhage, head trauma, infection, tumor, or complications of surgery. However, many people develop NPH even when none of these factors are present. In these cases the cause of the disorder is unknown. Symptoms of NPH include progressive mental impairment and dementia, problems with walking, and impaired bladder control. The person also may have a general slowing of movements or may complain that his or her feet feel "stuck." Because these symptoms are similar to those of other disorders such as Alzheimer's disease, Parkinson's disease, and Creutzfeldt-Jakob disease, the disorder is often misdiagnosed. Many cases go unrecognized and are never properly treated. Doctors may use a variety of tests, including brain scans (CT and/or MRI), a spinal tap or lumbar catheter, intracranial pressure monitoring, and neuropsychological tests, to help them diagnose NPH and rule out other conditions. </s>

<s>[INST] What are the treatments for Normal Pressure Hydrocephalus ? [/INST] Treatment for NPH involves surgical placement of a shunt in the brain to drain excess CSF into the abdomen where it can be absorbed as part of the normal circulatory process. This allows the brain ventricles to return to their normal size. Regular follow-up care by a physician is important in order to identify subtle changes that might indicate problems with the shunt. </s>

<s>[INST] What is the outlook for Normal Pressure Hydrocephalus ? [/INST] The symptoms of NPH usually get worse over time if the condition is not treated, although some people may experience temporary improvements. While the success of treatment with shunts varies from person to person, some people recover almost completely after treatment and have a good quality of life. Early diagnosis and treatment improves the chance of a good recovery. Without treatment, symptoms may worsen and cause death. </s>

<s>[INST] what research (or clinical trials) is being done for Normal Pressure Hydrocephalus ? [/INST] The NINDS conducts and supports research on neurological disorders, including normal pressure hydrocephalus. Research on disorders such as normal pressure hydrocephalus focuses on increasing knowledge and understanding of the disorder, improving diagnostic techniques and neuroimaging, and finding improved treatments and preventions. </s>

<s>[INST] What is (are) Miller Fisher Syndrome ? [/INST] Miller Fisher syndrome is a rare, acquired nerve disease that is considered to be a variant of Guillain-Barr syndrome. It is characterized by abnormal muscle coordination, paralysis of the eye muscles, and absence of the tendon reflexes. Like Guillain-Barr syndrome, symptoms may be preceded by a viral illness. Additional symptoms include generalized muscle weakness and respiratory failure. The majority of individuals with Miller Fisher syndrome have a unique antibody that characterizes the disorder. </s>

<s>[INST] What are the treatments for Miller Fisher Syndrome ? [/INST] Treatment for Miller Fisher syndrome is identical to treatment for Guillain-Barr syndrome: intravenous immunoglobulin (IVIg) or plasmapheresis (a procedure in which antibodies are removed from the blood) and supportive care. </s>

<s>[INST] What is the outlook for Miller Fisher Syndrome ? [/INST] The prognosis for most individuals with Miller Fisher syndrome is good. In most cases, recovery begins within 2 to 4 weeks of the onset of symptoms, and may be almost complete within 6 months. Some individuals are left with residual deficits. Relapses may occur rarely (in less than 3 percent of cases). </s>

<s>[INST] what research (or clinical trials) is being done for Miller Fisher Syndrome ? [/INST] The NINDS supports research aimed at discovering new ways to diagnose, treat, and, ultimately, cure neuropathies such as Miller Fisher syndrome. </s>

<s>[INST] What is (are) Chronic Pain ? [/INST] While acute pain is a normal sensation triggered in the nervous system to alert you to possible injury and the need to take care of yourself, chronic pain is different. Chronic pain persists. Pain signals keep firing in the nervous system for weeks, months, even years. There may have been an initial mishap -- sprained back, serious infection, or there may be an ongoing cause of pain -- arthritis, cancer, ear infection, but some people suffer chronic pain in the absence of any past injury or evidence of body damage. Many chronic pain conditions affect older adults. Common chronic pain complaints include headache, low back pain, cancer pain, arthritis pain, neurogenic pain (pain resulting from damage to the peripheral nerves or to the central nervous system itself), psychogenic pain (pain not due to past disease or injury or any visible sign of damage inside or outside the nervous system). A person may have two or more co-existing chronic pain conditions. Such conditions can include chronic fatigue syndrome, endometriosis, fibromyalgia, inflammatory bowel disease, interstitial cystitis, temporomandibular joint dysfunction, and vulvodynia. It is not known whether these disorders share a common cause. </s>

<s>[INST] What are the treatments for Chronic Pain ? [/INST] Medications, acupuncture, local electrical stimulation, and brain stimulation, as well as surgery, are some treatments for chronic pain. Some physicians use placebos, which in some cases has resulted in a lessening or elimination of pain. Psychotherapy, relaxation and medication therapies, biofeedback, and behavior modification may also be employed to treat chronic pain. </s>

<s>[INST] What is the outlook for Chronic Pain ? [/INST] Many people with chronic pain can be helped if they understand all the causes of pain and the many and varied steps that can be taken to undo what chronic pain has done. Scientists believe that advances in neuroscience will lead to more and better treatments for chronic pain in the years to come. </s>

<s>[INST] what research (or clinical trials) is being done for Chronic Pain ? [/INST] Clinical investigators have tested chronic pain patients and found that they often have lower-than-normal levels of endorphins in their spinal fluid. Investigations of acupuncture include wiring the needles to stimulate nerve endings electrically (electroacupuncture), which some researchers believe activates endorphin systems. Other experiments with acupuncture have shown that there are higher levels of endorphins in cerebrospinal fluid following acupuncture. Investigators are studying the effect of stress on the experience of chronic pain. Chemists are synthesizing new analgesics and discovering painkilling virtues in drugs not normally prescribed for pain. </s>

<s>[INST] What is (are) Adrenoleukodystrophy ? [/INST] X-linked Adrenoleukodystrophy (ALD) is one of a group of genetic disorders called the leukodystrophies that cause damage to the myelin sheath, an insulating membrane that surrounds nerve cells in the brain. Women have two X chromosomes and are the carriers of the disease, but since men only have one X chromosome and lack the protective effect of the extra X chromosome, they are more severely affected. People with X-ALD accumulate high levels of saturated, very long chain fatty acids (VLCFA) in the brain and adrenal cortex. The loss of myelin and the progressive dysfunction of the adrenal gland are the primary characteristics of X-ALD. While nearly all patients with X-ALD suffer from adrenal insufficiency, also known as Addison's disease, the neurological symptoms can begin either in childhood or in adulthood. The childhood cerebral form is the most severe, with onset between ages 4 and 10. The most common symptoms are usually behavioral changes such as abnormal withdrawal or aggression, poor memory, and poor school performance. Other symptoms include visual loss, learning disabilities, seizures, poorly articulated speech, difficulty swallowing, deafness, disturbances of gait and coordination, fatigue, intermittent vomiting, increased skin pigmentation, and progressive dementia. The milder adult-onset form is also known as adrenomyeloneuropathy (AMN), which typically begins between ages 21 and 35. Symptoms may include progressive stiffness, weakness or paralysis of the lower limbs, and ataxia. Although adult-onset ALD progresses more slowly than the classic childhood form, it can also result in deterioration of brain function. Almost half the women who are carriers of X-ALS will develop a milder form of AMN but almost never will develop symptoms seen in boys the X-ALD. X-ALD should not be confused with neonatal adrenoleukodsystrophy, which is a disease of newborns and young infants and belongs to the group of peroxisomal biogenesis disorders. </s>

<s>[INST] What are the treatments for Adrenoleukodystrophy ? [/INST] Adrenal function must be tested periodically in all patients with ALD. Treatment with adrenal hormones can be lifesaving. Symptomatic and supportive treatments for ALD include physical therapy, psychological support, and special education. Recent evidence suggests that a mixture of oleic acid and erucic acid, known as "Lorenzo's Oil," administered to boys with X-ALD prior to symptom onset can prevent or delay the appearance of the childhood cerebral form It is not known whether Lorenzo's Oil will have any beneficial effects in AMN. Furthermore, Lorenzo's Oil has no beneficial effect in symptomatic boys with X-ALD. Bone marrow transplantations can provide long-term benefit to boys who have early evidence of the childhood cerebral form of X-ALD, but the procedure carries risk of mortality and morbidity and is not recommended for those whose symptoms are already severe or who have the adult-onset or neonatal forms. </s>

<s>[INST] What is the outlook for Adrenoleukodystrophy ? [/INST] Prognosis for patients with childhood cerebral X-ALD is generally poor due to progressive neurological deterioration unless bone marrow transplantation is performed early. Death usually occurs within 1 to 10 years after the onset of symptoms. Adult-onset AMN will progress over decades. </s>

<s>[INST] what research (or clinical trials) is being done for Adrenoleukodystrophy ? [/INST] The NINDS supports research on genetic disorders such as ALD. The aim of this research is to find ways to prevent, treat, and cure these disorders. Studies are currently underway to identify new biomarkers of disease progression and to determine which patients will develop the childhood cerebral form of X-ALD. A recent case study in Europe demonstrated that the combination of gene therapy with bone marrow transplantation, using the patient's own bone marrow cells, may arrest disease progression in childhood cerebral X-ALD. A therapeutic trail in the United States is currently being discussed with the U.S. Food and Drug Administration. </s>

<s>[INST] What is (are) Hydromyelia ? [/INST] Hydromyelia refers to an abnormal widening of the central canal of the spinal cord that creates a cavity in which cerebrospinal fluid (commonly known as spinal fluid) can accumulate. As spinal fluid builds up, it may put abnormal pressure on the spinal cord and damage nerve cells and their connections. Hydromyelia is sometimes used interchangeably with syringomyelia, the name for a condition that also involves cavitation in the spinal cord. In hydromyelia, the cavity that forms is connected to the fourth ventricle in the brain, and is almost always associated in infants and children with hydrocephalus or birth defects such as Chiari Malformation II and Dandy-Walker syndrome. Syringomyelia, however, features a closed cavity and occurs primarily in adults, the majority of whom have Chiari Malformation type 1 or have experienced spinal cord trauma. Symptoms, which may occur over time, include weakness of the hands and arms, stiffness in the legs; and sensory loss in the neck and arms. Some individuals have severe pain in the neck and arms. Diagnosis is made by magnetic resonance imaging (MRI), which reveals abnormalities in the anatomy of the spinal cord.. </s>

<s>[INST] What are the treatments for Hydromyelia ? [/INST] Generally, physicians recommend surgery for children with hydromyelia if they have moderate or severe neurological deficits. Surgical treatment re-establishes the normal flow of spinal fluid. </s>

<s>[INST] What is the outlook for Hydromyelia ? [/INST] Surgery may permanently or temporarily relieve symptoms, but it can also cause a number of severe complications. In rare cases, hydromyelia may resolve on its own without any medical intervention. </s>

<s>[INST] what research (or clinical trials) is being done for Hydromyelia ? [/INST] The National Institute of Neurological Disorders and Stroke (NINDS) conducts research related to hydromyelia in its clinics and laboratories at The National Institutes of Health (NIH) and supports additional research through grants to major research institutions across the country. Much of this research focuses on finding better ways to prevent, treat, and ultimately cure abnormalities of the spinal cord such as hydromyelia. </s>

<s>[INST] What is (are) Joubert Syndrome ? [/INST] Joubert syndrome is a rare brain malformation characterized by the absence or underdevelopment of the cerebellar vermis- an area of the brain that controls balance and coordination -- as well as a malformed brain stem (molar tooth sign). The most common features of Joubert syndrome in infants include abnormally rapid breathing (hyperpnea), decreased muscle tone (hypotonia), abnormal eye movements, impaired intellectual development, and the inability to coordinate voluntary muscle movements (ataxia). Physical deformities may be present, such as extra fingers and toes (polydactyly), cleft lip or palate, and tongue abnormalities. Kidney and liver abnormalities can develop, and seizures may also occur. Many cases of Joubert syndrome appear to be sporadic (not inherited). In most other cases, Joubert syndrome is inherited in an autosomal recessive manner (meaning both parents must have a copy of the mutation) via mutation in at least 10 different genes, including NPHP1, AHI1, and CEP290. </s>

<s>[INST] What are the treatments for Joubert Syndrome ? [/INST] Treatment for Joubert syndrome is symptomatic and supportive. Infant stimulation and physical, occupational, and speech therapy may benefit some children. Infants with abnormal breathing patterns should be monitored. Screening for progressive eye, liver, and kidney complications associated with Joubert-related disorders should be performed on a regular basis. </s>

<s>[INST] What is the outlook for Joubert Syndrome ? [/INST] The prognosis for infants with Joubert syndrome depends on whether or not the cerebellar vermis is partially developed or entirely absent, as well as on the extent and severity of other organ involvement, such as the kidneys and liver. Some children have a mild form of the disorder, with minimal motor disability and good mental development, while others may have severe motor disability, moderate impaired mental development, and multi-organ impairments. </s>

<s>[INST] what research (or clinical trials) is being done for Joubert Syndrome ? [/INST] The NINDS supports research on the development of the nervous system and the cerebellum. This research is critical for increasing our understanding of Joubert syndrome, and for developing methods of treatment and prevention. NINDS, in conjunction with the NIH Office of Rare Disorders, sponsored a symposium on Joubert syndrome in 2002. Research priorities for the disorder were outlined at this meeting. </s>

<s>[INST] What is (are) Infantile Spasms ? [/INST] An infantile spasm (IS) is a specific type of seizure seen in an epilepsy syndrome of infancy and childhood known as West Syndrome. West Syndrome is characterized by infantile spasms, developmental regression, and a specific pattern on electroencephalography (EEG) testing called hypsarrhythmia (chaotic brain waves). The onset of infantile spasms is usually in the first year of life, typically between 4-8 months. The seizures primarily consist of a sudden bending forward of the body with stiffening of the arms and legs; some children arch their backs as they extend their arms and legs. Spasms tend to occur upon awakening or after feeding, and often occur in clusters of up to 100 spasms at a time. Infants may have dozens of clusters and several hundred spasms per day. Infantile spasms usually stop by age five, but may be replaced by other seizure types. Many underlying disorders, such as birth injury, metabolic disorders, and genetic disorders can give rise to spasms, making it important to identify the underlying cause. In some children, no cause can be found. </s>

<s>[INST] What are the treatments for Infantile Spasms ? [/INST] Treatment with corticosteroids such as prednisone is standard, although serious side effects can occur. Several newer antiepileptic medications, such as topiramate may ease some symptoms. Vigabatrin (Sabril) has been approved by the U.S. Food and Drug Administration to treat infantile spasms in children ages one month to two years. Some children have spasms as the result of brain lesions, and surgical removal of these lesions may result in improvement. </s>

<s>[INST] What is the outlook for Infantile Spasms ? [/INST] The prognosis for children with IS is dependent on the underlying causes of the seizures. The intellectual prognosis for children with IS is generally poor because many babies with IS have neurological impairment prior to the onset of spasms. Epileptic spasms usually reduce in number by mid-childhood, but more than half of the children with IS will develop other types of seizures. There appears to be a close relationship between IS and Lennox-Gastaut Syndrome, an epileptic disorder of later childhood. </s>

<s>[INST] what research (or clinical trials) is being done for Infantile Spasms ? [/INST] The NINDS supports broad and varied programs of research on epilepsy and other seizure disorders. This research is aimed at discovering new ways to prevent, diagnose, and treat these disorders and, ultimately, to find cures for them. Hopefully, more effective and safer treatments, such as neuroprotective agents, will be developed to treat IS and West Syndrome. </s>

<s>[INST] What is (are) Arachnoid Cysts ? [/INST] Arachnoid cysts are cerebrospinal fluid-filled sacs that are located between the brain or spinal cord and the arachnoid membrane, one of the three membranes that cover the brain and spinal cord. Primary arachnoid cysts are present at birth and are the result of developmental abnormalities in the brain and spinal cord that arise during the early weeks of gestation. Secondary arachnoid cysts are not as common as primary cysts and develop as a result of head injury, meningitis, or tumors, or as a complication of brain surgery. The majority of arachnoid cysts form outside the temporal lobe of the brain in an area of the skull known as the middle cranial fossa. Arachnoid cysts involving the spinal cord are rarer. The location and size of the cyst determine the symptoms and when those symptoms begin. Most individuals with arachnoid cysts develop symptoms before the age of 20, and especially during the first year of life, but some people with arachnoid cysts never have symptoms. Males are four times more likely to have arachnoid cysts than females. Typical symptoms of an arachnoid cyst around the brain include headache, nausea and vomiting, seizures, hearing and visual disturbances, vertigo, and difficulties with balance and walking. Arachnoid cysts around the spinal cord compress the spinal cord or nerve roots and cause symptoms such as progressive back and leg pain and tingling or numbness in the legs or arms. Diagnosis usually involves a brain scan or spine scan using diffusion-weighted MRI (magnetic resonance imaging) which helps distinguish fluid-filled arachnoid cysts from other types of cysts. </s>

<s>[INST] What are the treatments for Arachnoid Cysts ? [/INST] There has been active debate about how to treat arachnoid cysts. The need for treatment depends mostly upon the location and size of the cyst. If the cyst is small, not disturbing surrounding tissue, and not causing symptoms, some doctors will refrain from treatment. In the past, doctors placed shunts in the cyst to drain its fluid. Now with microneurosurgical techniques and endoscopic tools that allow for minimally invasive surgery, more doctors are opting to surgically remove the membranes of the cyst or open the cyst so its fluid can drain into the cerebrospinal fluid and be absorbed. </s>

<s>[INST] What is the outlook for Arachnoid Cysts ? [/INST] Untreated, arachnoid cysts may cause permanent severe neurological damage when progressive expansion of the cyst(s) or bleeding into the cyst injures the brain or spinal cord. Symptoms usually resolve or improve with treatment. </s>

<s>[INST] what research (or clinical trials) is being done for Arachnoid Cysts ? [/INST] The National Institute of Neurological Disorders and Stroke (NINDS) conducts research related to brain abnormalities and disorders of the nervous system such as arachnoid cysts in laboratories at the National Institutes of Health (NIH), and supports additional research through grants to major medical institutions across the country. Much of this research focuses on finding better ways to prevent, treat, and ultimately cure neurological disorders such as arachnoid cysts. </s>

<s>[INST] What is (are) Behcet's Disease ? [/INST] Behcet's disease is a rare, chronic inflammatory disorder. The cause of Behcet's disease is unknown, but current research suggests that both genetic and environmental factors play a role. Behcet's disease generally begins when individuals are in their 20s or 30s, although it can happen at any age. It tends to occur more often in men than in women. Symptoms of Behcet's disease include recurrent ulcers in the mouth (resembling canker sores) and on the genitals, and eye inflammation. The disorder may also cause various types of skin lesions, arthritis, bowel inflammation, meningitis (inflammation of the membranes of the brain and spinal cord), and cranial nerve palsies. Behcet's is a multi-system disease; it may involve all organs and affect the central nervous system, causing memory loss and impaired speech, balance, and movement. The effects of the disease may include blindness, stroke, swelling of the spinal cord, and intestinal complications. The disease is common in the Middle East, particularly in Turkey, and in Far Eastern nations such as Japan and Korean, but is less common in the United States. </s>

<s>[INST] What is (are) Pelizaeus-Merzbacher Disease ? [/INST] Pelizaeus-Merzbacher disease (PMD) is a rare, progressive, degenerative central nervous system disorder in which coordination, motor abilities, and intellectual function deteriorate. The disease is one of a group of gene-linked disorders known as the leukodystrophies, which affect growth of the myelin sheath -- the fatty covering that wraps around and protects nerve fibers in the brain. The disease is caused by a mutation in the gene that controls the production of a myelin protein called proteolipid protein-1 (PLP1). PMD is inherited as an X-linked recessive trait; the affected individuals are male and the mothers are carriers of the PLP1 mutation. Severity and onset of the disease ranges widely, depending on the type of PLP1 mutation. PMD is one of a spectrum of diseases associated with PLP1, which also includes Spastic Paraplegia Type 2 (SPG2). The PLP1-related disorders span a continuum of neurologic symptoms that range from severe central nervous system involvement (PMD) to progressive weakness and stiffness of the legs (SPG2). There are four general classifications within this spectrum of diseases. In order of severity, they are: - Connatal PMD, which is the most severe type and involves delayed mental and physical development and severe neurological symptoms; - Classic PMD, in which the early symptoms include muscle weakness, involuntary movements of the eyes (nystagmus), and delays in motor development within the first year of life; - Complicated SPG2, which features motor development issues and brain involvement, and, - Pure SPG2, which includes cases of PMD that do not have neurologic complications. Noticeable changes in the extent of myelination can be detected by MRI analyses of the brain. Additional symptoms of PMD may include slow growth, tremor, failure to develop normal control of head movement, and deteriorating speech and cognitive function. </s>

<s>[INST] What is (are) Barth Syndrome ? [/INST] Barth syndrome (BTHS) is a rare, genetic disorder of lipid metabolism that primarily affects males. It is caused by a mutation in the tafazzin gene (TAZ, also called G4.5) which leads to decreased production of an enzyme required to produce cardiolipin. Cardiolipin is an essential lipid that is important in energy metabolism. BTHS, which affects multiple body systems, is considered serious. Its main characteristics often include combinations in varying degrees of heart muscle weakness (cardiomyopathy), neutropenia (low white blood cell cunt, which may lead to an increased risk for bacterial infections), reduced muscle tone (hypotonia), muscle weakness, undeveloped skeletal muscles, delayed growth, fatigue, varying degrees of physical disability, and methylglutaconic aciduria (an increase in an organic acid that results in abnormal mitochondria function). Although some with BTHS may have all of these characteristics, others may have only one or two and are often misdiagnosed. BTHS is an X-linked genetic condition passed from mother to son through the X chromosome. A mother who is a carrier of BTHS typically shows no signs or symptoms of the disorder herself. On average, 50 percent of children born to a carrier mother will inherit the defective gene, but only boys will develop symptoms. All daughters born to an affected male will be carriers but typically will not have symptoms. </s>

<s>[INST] What are the treatments for Barth Syndrome ? [/INST] There is no specific treatment for Barth syndrome. Bacterial infections caused by neutropenia can be effectively treated with antibiotics. The drug granulocyte colony stimulating factor, or GCSF, can stimulate white cell production by the bone marrow and help combat infection. Medicines may be prescribed to control heart problems. The dietary supplement carnitine has aided some children with Barth syndrome but in others it has caused increasing muscle weakness and even precipitated heart failure. Only careful dietary monitoring directed by a physician or nutritionist familiar with the disorder can ensure proper caloric and nutritional intake. </s>

<s>[INST] What is the outlook for Barth Syndrome ? [/INST] Early and accurate diagnosis is key to prolonged survival for boys born with Barth syndrome. The disorder was once considered uniformly fatal in infancy, but some individuals are now living much longer. Severe infections and cardiac failure are common causes of death in affected children. </s>

<s>[INST] what research (or clinical trials) is being done for Barth Syndrome ? [/INST] The mission of the National Institute of Neurological Disorders and Stroke (NINDS) is to seek fundamental knowledge of the brain and nervous system and to use that knowledge to reduce the burden of neurological disease. The NINDS supports research on genetic disorders such as Barth syndrome, including basic research on mitochondrial dysfunction and investigations of other inborn errors of metabolism. Scientists have identified many of the genetic mutations that cause mitochondrial diseases and have created animal models which can be used to investigate potential treatments. Scientists hope to develop unique approaches to treating mitochondrial diseases through a better understanding of mitochondrial biology. Because people affected by mitochondrial disease often have a mixture of healthy and mutant mitochondria in their cells, effective therapy could involve getting the healthy mitochondria to take over for the diseased ones. </s>

<s>[INST] What is (are) Pervasive Developmental Disorders ? [/INST] The diagnostic category of pervasive developmental disorders (PDD) refers to a group of disorders characterized by delays in the development of socialization and communication skills. Parents may note symptoms as early as infancy, although the typical age of onset is before 3 years of age. Symptoms may include problems with using and understanding language; difficulty relating to people, objects, and events; unusual play with toys and other objects; difficulty with changes in routine or familiar surroundings, and repetitive body movements or behavior patterns. Autism (a developmental brain disorder characterized by impaired social interaction and communication skills, and a limited range of activities and interests) is the most characteristic and best studied PDD. Other types of PDD include Asperger's Syndrome, Childhood Disintegrative Disorder, and Rett's Syndrome. Children with PDD vary widely in abilities, intelligence, and behaviors. Some children do not speak at all, others speak in limited phrases or conversations, and some have relatively normal language development. Repetitive play skills and limited social skills are generally evident. Unusual responses to sensory information, such as loud noises and lights, are also common. </s>

<s>[INST] What are the treatments for Pervasive Developmental Disorders ? [/INST] There is no known cure for PDD. Medications are used to address specific behavioral problems; therapy for children with PDD should be specialized according to need. Some children with PDD benefit from specialized classrooms in which the class size is small and instruction is given on a one-to-one basis. Others function well in standard special education classes or regular classes with additional support. </s>

<s>[INST] What is (are) Krabbe Disease ? [/INST] Krabbe disease is a rare, inherited metabolic disorder in which harmful amounts of lipids (fatty materials such as oils and waxes) build up in various cells and tissues in the body and destroys brain cells. Krabbe disease, also known as globoid cell leukodystrophy, ischaracterized by the presence of globoid cells (cells that have more than one nucleus) that break down the nerves protective myelin coating. Krabbe disease is caused by a deficiency of galactocerebrosidase, an essential enzyme for myelin metabolism. The disease most often affects infants, with onset before age 6 months, but can occur in adolescence or adulthood. Symptoms include severe deterioration of mental and motor skills, muscle weakness, hypertonia (inability of a muscle to stretch), myoclonic seizures (sudden, shock-like contractions of the limbs), and spasticity (involuntary and awkward movement). Other symptoms may include irritability, unexplained fever, blindness, difficulty with swallowing, and deafness. </s>

<s>[INST] What are the treatments for Krabbe Disease ? [/INST] There is no cure for Krabbe disease. Results of a very small clinical trial of children with infantile Krabbe disease found that children who received umbilical cord blood stem cells from unrelated donors prior to symptom onset developed with little neurological impairment. Bone marrow transplantation may help some people. Generally, treatment for the disorder is symptomatic and supportive. Physical therapy may help maintain or increase muscle tone and circulation. </s>

<s>[INST] What is the outlook for Krabbe Disease ? [/INST] Krabbe disease in infants is generally fatal before age 2. Individuals with a later onset form of the disease generally have a milder course of the disease and live significantly longer. </s>

Hamatopoietic stem cell transplantation -- using stem cells from umbilical cord blood or bone marrow -- has been shown to benefit some individuals when given early in the course of the disease. Scientists plan to test hematopoietic stem cell transplantation plus gene therapy to see if it dramatically increases life expectancy in a mouse model of the disease. Also in a mouse mode, NINDS-funded scientists are testing a combined treatment approach that uses a harmless virus to increase protein production, along with blood stem cell transplantation and small-molecule-based drugs, to reduce neuroinflammation, cell death, and nerve cell degeneration seen in Krabbe disease. </s>

<s>[INST] What is (are) Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) ? [/INST] Chronic inflammatory demyelinating polyneuropathy (CIDP) is a neurological disorder characterized by progressive weakness and impaired sensory function in the legs and arms. The disorder, which is sometimes called chronic relapsing polyneuropathy, is caused by damage to the myelin sheath (the fatty covering that wraps around and protects nerve fibers) of the peripheral nerves. Although it can occur at any age and in both genders, CIDP is more common in young adults, and in men more so than women. It often presents with symptoms that include tingling or numbness (beginning in the toes and fingers), weakness of the arms and legs, loss of deep tendon reflexes (areflexia), fatigue, and abnormal sensations. CIDP is closely related to Guillain-Barre syndrome and it is considered the chronic counterpart of that acute disease. </s>

<s>[INST] What are the treatments for Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) ? [/INST] Treatment for CIDP includes corticosteroids such as prednisone, which may be prescribed alone or in combination with immunosuppressant drugs. Plasmapheresis (plasma exchange) and intravenous immunoglobulin (IVIg) therapy are effective. IVIg may be used even as a first-line therapy. Physiotherapy may improve muscle strength, function and mobility, and minimize the shrinkage of muscles and tendons and distortions of the joints. </s>

<s>[INST] What is the outlook for Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) ? [/INST] The course of CIDP varies widely among individuals. Some may have a bout of CIDP followed by spontaneous recovery, while others may have many bouts with partial recovery in between relapses. The disease is a treatable cause of acquired neuropathy and initiation of early treatment to prevent loss of nerve axons is recommended.

<s>[INST] What is (are) Asperger Syndrome ? [/INST] Asperger syndrome (AS) is a developmental disorder. It is an autism spectrum disorder (ASD), one of a distinct group of neurological conditions characterized by a greater or lesser degree of impairment in language and communication skills, as well as repetitive or restrictive patterns of thought and behavior. Other ASDs include: classic autism, Rett syndrome, childhood disintegrative disorder, and pervasive developmental disorder not otherwise specified (usually referred to as PDD-NOS). Unlike children with autism, children with AS retain their early language skills. The most distinguishing symptom of AS is a childs obsessive interest in a single object or topic to the exclusion of any other. Children with AS want to know everything about their topic of interest and their conversations with others will be about little else. Their expertise, high level of vocabulary, and formal speech patterns make them seem like little professors. Other characteristics of AS include repetitive routines or rituals; peculiarities in speech and language; socially and emotionally inappropriate behavior and the inability to interact successfully with peers; problems with non-verbal communication; and clumsy and uncoordinated motor movements. Children with AS are isolated because of their poor social skills and narrow interests. They may approach other people, but make normal conversation impossible by inappropriate or eccentric behavior, or by wanting only to talk about their singular interest.Children with AS usually have a history of developmental delays in motor skills such as pedaling a bike, catching a ball, or climbing outdoor play equipment. They are often awkward and poorly coordinated with a walk that can appear either stilted or bouncy. </s>

<s>[INST] What are the treatments for Asperger Syndrome ? [/INST] The ideal treatment for AS coordinates therapies that address the three core symptoms of the disorder: poor communication skills, obsessive or repetitive routines, and physical clumsiness. There is no single best treatment package for all children with AS, but most professionals agree that the earlier the intervention, the better. An effective treatment program builds on the childs interests, offers a predictable schedule, teaches tasks as a series of simple steps, actively engages the childs attention in highly structured activities, and provides regular reinforcement of behavior. It may include social skills training, cognitive behavioral therapy, medication for co-existing conditions, and other measures. </s>

<s>[INST] What is the outlook for Asperger Syndrome ? [/INST] With effective treatment, children with AS can learn to cope with their disabilities, but they may still find social situations and personal relationships challenging.

<s>[INST] What is (are) Corticobasal Degeneration ? [/INST] Corticobasal degeneration is a progressive neurological disorder characterized by nerve cell loss and atrophy (shrinkage) of multiple areas of the brain including the cerebral cortex and the basal ganglia. Corticobasal degeneration progresses gradually. Initial symptoms, which typically begin at or around age 60, may first appear on one side of the body (unilateral), but eventually affect both sides as the disease progresses. Symptoms are similar to those found in Parkinson disease, such as poor coordination, akinesia (an absence of movements), rigidity (a resistance to imposed movement), disequilibrium (impaired balance); and limb dystonia (abnormal muscle postures). Other symptoms such as cognitive and visual-spatial impairments, apraxia (loss of the ability to make familiar, purposeful movements), hesitant and halting speech, myoclonus (muscular jerks), and dysphagia (difficulty swallowing) may also occur. An individual with corticobasal degeneration eventually becomes unable to walk. </s>

<s>[INST] What are the treatments for Corticobasal Degeneration ? [/INST] There is no treatment available to slow the course of corticobasal degeneration, and the symptoms of the disease are generally resistant to therapy.

<s>[INST] What is (are) Mucopolysaccharidoses ? [/INST] The mucopolysaccharidoses are a group of inherited metabolic diseases in which a defective or missing enzyme causes large amounts of complex sugar molecules to accumulate in harmful amounts in the body's cells and tissues. This accumulation causes permanent, progressive cellular damage that affects appearance, physical abilities, organ and system functioning, and, in most cases, mental development.Depending on the type of mucopolysaccharidosis, affected individuals may have normal intellect or may be profoundly impaired, may experience developmental delay, or have severe behavioral problems. Physical symptoms generally include coarse or rough facial features, thick lips, an enlarged mouth and tongue, short stature with a disproportionately short trunk (dwarfism), abnormal bone size or shape (and other skeletal irregularities), thickened skin, enlarged organs such as the liver or spleen, hernias, and excessive body hair growth. </s>

<s>[INST] What are the treatments for Mucopolysaccharidoses ?

Physical therapy and daily exercise may delay joint problems and improve the ability to move.Surgery to remove tonsils and adenoids may improve breathing among affected individuals with obstructive airway disorders and sleep apnea. Surgery can also correct hernias, help drain excessive cerebrospinal fluid from the brain, and free nerves and nerve roots compressed by skeletal and other abnormalities. Corneal transplants may improve vision among individuals with significant corneal clouding.Enzyme replacement therapies are currently in use for several MPS disorders and are beig tested in the other MPS disorders. Enzyme replacement therapy has proven useful in reducing non-neurological symptoms and pain. </s>

<s>[INST] What is the outlook for Mucopolysaccharidoses ? [/INST] The mucopolysaccharidoses syndromes share many clinical features but have varying degrees of severity. Most individuals with a mucopolysaccharidosis syndrome generally experience a period of normal development followed by a decline in physical and mental function. Longevity is dependent upon the particular syndrome. For example, children with a form of mucopolysaccharidosis called Hurler syndrome often die before age 10 from obstructive airway disease, respiratory infections, or cardiac complications. A child with the type known as Scheie syndrome can live into adulthood, while one with a mild case of the type known as Hunter syndrome may live into his or her 50s or beyond. </s>

In some cases, internal bleeding may occur as a result of blood vessel malformations involving organs such as the stomach, rectum, vagina, liver, spleen, bladder, kidneys, lungs, or heart. Individuals are also at risk for blood clots. The cause of the disorder is unknown. A similar port-wine stain disorder in which individuals have vascular anomalies on the face as well as in the brain is Sturge-Weber syndrome. These individuals may experience seizures and mental deficiency. In some cases, features of the Klippel-Trenaunay syndrome and Sturge-Weber syndrome coincide.
