Question:  What is (are) Aicardi Syndrome ?
Answer: Aicardi syndrome is a rare genetic disorder that primarily affects newborn girls. The condition is sporadic, meaning it is not known to pass from parent to child. (An exception is a report of two sisters and a pair of identical twins, all of whom were affected.) The mutation that causes Aicardi syndrome has not been identified, but it is thought to be caused by a dominant mutation that appears for the first time in a family in an x-linked gene that may be lethal in certain males.. Aicardi syndrome can be seen in boys born with an extra "X" chromosome. (Females have two X chromosomes, while males normally have an X and a Y chromosome.) The precise gene or genetic mechanism causing Aicardi syndrome is not yet known.
                
Originally, Aicardi syndrome was characterized by three main features: 1) partial or complete absence of the structure (corpus callosum) that links the two halves of the brain (2) infantile spasms (a type of seizure disorder), and 3) chorioretinal lacunae, lesions on the retina that look like yellowish spots. However, Aicardi syndrome is now known to have a much broader spectrum of abnormalities than was initially described. Not all girls with the condition have the three features described above and many girls have additional feature such as lower tone around the head and trunk, microcephaly (small head circumference), and spasticity in the limbs.
                
Typical findings in the brain of girls with Aicardi syndrome include heterotopias, which are groups of brain cells that, during development, migrated to the wrong area of brain; polymicrogyria or pachygyria, which are numerous small, or too few, brain folds; and cysts, (fluid filled cavities) in the brain. Girls with Aicardi syndrome have varying degrees of intellectual disability and developmental delay. Many girls also have developmental abnormalities of their optic nerves and some have microphthalmia (small eyes). Skeletal problems such as absent or abnormal ribs and abnormalities of vertebrae in the spinal column (including hemivertebrae and butterfly vertebrae) have also been reported. Some girls also have skin problems, facial asymmetry, small hands, and an increased incidence of tumors.
                
(Aicardi syndrome is distinct from Aicardi-Goutieres syndrome, which is an inherited encephalopathy that affects newborn infants.)
Question:  What are the treatments for Aicardi Syndrome ?
Answer: There is no cure for Aicardi syndrome nor is there a standard course of treatment. Treatment generally involves medical management of seizures and programs to help parents and children cope with developmental delays. Long-term management by a pediatric neurologist with expertise in the management of infantile spasms is recommended.
Question:  What is the outlook for Aicardi Syndrome ?
Answer: The prognosis for girls with Aicardi syndrome varies according to the severity of their symptoms. There is an increased risk for death in childhood and adolescence, but survivors into adulthood have been described.
Question:  what research (or clinical trials) is being done for Aicardi Syndrome ?
Answer: The NINDS supports and conducts research on neurogenetic disorders such as Aicardi syndrome. The goals of this research are to locate and understand the genes involved and to develop techniques to diagnose, treat, prevent, and ultimately cure disorders such as Aicardi syndrome.
Question:  What is (are) Refsum Disease ?
Answer: Adult Refsum disease (ARD) is a rare genetic disease that causes weakness or numbness of the hands and feet (peripheral neuropathy). Due to a genetic abnormality, people with ARD disease lack the enzyme in peroxisomes that break down phytanic acid, a type of fat found in certain foods. As a result, toxic levels of phytanic acid build up in the brain, blood, and other tissues. The disease usually begins in late childhood or early adulthood with increasing night blindness due to degeneration of the retina (retinitis pigmentosa). If the disease progresses, other symptoms may include deafness, loss of the sense of smell (anosmia), problems with balance and coordination (ataxia), dry and scaly skin (ichthyosis), and heartbeat abnormalities (cardiac arrhythmias). Some individuals will have shortened bones in their fingers or toes, or a visibly shortened fourth toe. Although the disease usually appears in early childhood, some people will not develop symptoms until their 40s or 50s.
Question:  What are the treatments for Refsum Disease ?
Answer: The primary treatment for ARD is to restrict or avoid foods that contain phytanic acid, including dairy products; beef and lamb; and fatty fish such as tuna, cod, and haddock. Some individuals may also require plasma exchange (plasmapheresis) in which blood is drawn, filtered, and reinfused back into the body, to control the buildup of phytanic acid.
Question:  What is the outlook for Refsum Disease ?
Answer: ARD is treatable because phytanic acid is not produced by the body, but is only found in foods. With treatment, muscle weakness, numbness, and dry and scaly skin generally disappear. However, vision and hearing problems may persist and the sense of smell may not return. Untreated, ARD can lead to sudden death caused by heartbeat abnormalities.
Question:  what research (or clinical trials) is being done for Refsum Disease ?
Answer: The National Institute of Neurological Disorders and Stroke (NINDS) supports research related to Adult Refsum Disease through grants to major research institutions across the country. Research is focused on finding better ways to prevent, treat, and ultimately cure ARD and other peroxisomal disorders.
Question:  What is (are) Frontotemporal Dementia ?
Answer: Frontotemporal dementia (FTD) describes a clinical syndrome associated with shrinking of the frontal and temporal anterior lobes of the brain. Originally known as Picks disease, the name and classification of FTD has been a topic of discussion for over a century. The current designation of the syndrome groups together Picks disease, primary progressive aphasia, and semantic dementia as FTD. Some doctors propose adding corticobasal degeneration and progressive supranuclear palsy to FTD and calling the group Pick Complex. These designations will continue to be debated. As it is defined today, the symptoms of FTD fall into two clinical patterns that involve either (1) changes in behavior, or (2) problems with language. The first type features behavior that can be either impulsive (disinhibited) or bored and listless (apathetic) and includes inappropriate social behavior; lack of social tact; lack of empathy; distractability; loss of insight into the behaviors of oneself and others; an increased interest in sex; changes in food preferences; agitation or, conversely, blunted emotions; neglect of personal hygiene; repetitive or compulsive behavior, and decreased energy and motivation. The second type primarily features symptoms of language disturbance, including difficulty making or understanding speech, often in conjunction with the behavioral types symptoms. Spatial skills and memory remain intact. There is a strong genetic component to the disease; FTD often runs in families.
Question:  What are the treatments for Frontotemporal Dementia ?
Answer: No treatment has been shown to slow the progression of FTD. Behavior modification may help control unacceptable or dangerous behaviors. Aggressive, agitated, or dangerous behaviors could require medication. Anti-depressants have been shown to improve some symptoms.
Question:  What is the outlook for Frontotemporal Dementia ?
Answer: The outcome for people with FTD is poor. The disease progresses steadily and often rapidly, ranging from less than 2 years in some individuals to more than 10 years in others. Eventually some individuals with FTD will need 24-hour care and monitoring at home or in an institutionalized care setting.
Question:  what research (or clinical trials) is being done for Frontotemporal Dementia ?
Answer: The National Institute of Neurological Disorders and Stroke (NINDS), and other institutes of the National Institutes of Health (NIH), conduct research related to FTD in laboratories at the NIH, and also support additional research through grants to major medical institutions across the country.
Question:  What is (are) Shaken Baby Syndrome ?
Answer: Shaken baby syndrome is a type of inflicted traumatic brain injury that happens when a baby is violently shaken. A baby has weak neck muscles and a large, heavy head. Shaking makes the fragile brain bounce back and forth inside the skull and causes bruising, swelling, and bleeding, which can lead to permanent, severe brain damage or death. The characteristic injuries of shaken baby syndrome are subdural hemorrhages (bleeding in the brain), retinal hemorrhages (bleeding in the retina), damage to the spinal cord and neck, and fractures of the ribs and bones. These injuries may not be immediately noticeable. Symptoms of shaken baby syndrome include extreme irritability, lethargy, poor feeding, breathing problems, convulsions, vomiting, and pale or bluish skin. Shaken baby injuries usually occur in children younger than 2 years old, but may be seen in children up to the age of 5.
Question:  What are the treatments for Shaken Baby Syndrome ?
Answer: Emergency treatment for a baby who has been shaken usually includes life-sustaining measures such as respiratory support and surgery to stop internal bleeding and bleeding in the brain. Doctors may use brain scans, such as MRI and CT, to make a more definite diagnosis.
Question:  What is the outlook for Shaken Baby Syndrome ?
Answer: In comparison with accidental traumatic brain injury in infants, shaken baby injuries have a much worse prognosis. Damage to the retina of the eye can cause blindness. The majority of infants who survive severe shaking will have some form of neurological or mental disability, such as cerebral palsy or cognitive impairment, which may not be fully apparent before 6 years of age. Children with shaken baby syndrome may require lifelong medical care.
Question:  what research (or clinical trials) is being done for Shaken Baby Syndrome ?
Answer: The National Institute of Neurological Disorders and Stroke (NINDS), and other institutes of the National Institutes of Health (NIH), conduct research related to shaken baby syndrome in laboratories at the NIH and also support additional research through grants to major medical institutions across the country. Much of this research focuses on finding better ways to treat and heal medical conditions such as shaken baby syndrome.
Question:  What is (are) Gerstmann-Straussler-Scheinker Disease ?
Answer: Gerstmann-Straussler-Scheinker disease (GSS) is an extremely rare, neurodegenerative brain disorder. It is almost always inherited and is found in only a few families around the world. Onset of the disease usually occurs between the ages of 35 and 55. In the early stages, patients may experience varying levels of ataxia (lack of muscle coordination), including clumsiness, unsteadiness, and difficulty walking. As the disease progresses, the ataxia becomes more pronounced and most patients develop dementia. Other symptoms may include dysarthria (slurring of speech), nystagmus (involuntary movements of the eyes), spasticity (rigid muscle tone), and visual disturbances, sometimes leading to blindness. Deafness also can occur. In some families, parkinsonian features are present. GSS belongs to a family of human and animal diseases known as the transmissible spongiform encephalopathies (TSEs). Other TSEs include Creutzfeldt-Jakob disease, kuru, and fatal familial insomnia.
Question:  What are the treatments for Gerstmann-Straussler-Scheinker Disease ?
Answer: There is no cure for GSS, nor are there any known treatments to slow progression of the disease. Current therapies are aimed at alleviating symptoms and making the patient as comfortable as possible.
Question:  What is the outlook for Gerstmann-Straussler-Scheinker Disease ?
Answer: GSS is a slowly progressive condition usually lasting from 2 to 10 years. The disease ultimately causes severe disability and finally death, often after the patient goes into a coma or has a secondary infection such as aspiration pneumonia due to an impaired ability to swallow.
Question:  what research (or clinical trials) is being done for Gerstmann-Straussler-Scheinker Disease ?
Answer: The NINDS supports and conducts research on TSEs, including GSS. Much of this research is aimed at characterizing the agents that cause these disorders, clarifying the mechanisms underlying them, and, ultimately, finding ways to prevent, treat, and cure them.
Question:  What is (are) Syringomyelia ?
Answer: Syringomyelia (sear-IN-go-my-EEL-ya) is a disorder in which a fluid-filled cyst forms within the spinal cord. This cyst, called a syrinx, expands and elongates over time, destroying the center of the spinal cord. Since the spinal cord connects the brain to nerves in the extremities, this damage results in pain, weakness, and stiffness in the back, shoulders, arms, or legs. Symptoms vary among individuals. Other symptoms may include headaches and a loss of the ability to feel extremes of hot or cold, especially in the hands.Signs of the disorder tend to develop slowly, although sudden onset may occur with coughing or straining. If not treated surgically, syringomyelia often leads to progressive weakness in the arms and legs, loss of hand sensation, and chronic, severe pain. In most cases, the disorder is related to a congenital abnormality of the brain called a Chiari I malformation. This malformation causes the lower part of the cerebellum to protrude from its normal location in the back of the head, through the hole connecting the skull and spine, and into the cervical or neck portion of the spinal canal. Syringomyelia may also occur as a complication of trauma, meningitis, hemorrhage, a tumor, or other condition. Symptoms may appear months or even years after the initial injury, starting with pain, weakness, and sensory impairment originating at the site of trauma. Some cases of syringomyelia are familial, although this is rare.
Question:  What are the treatments for Syringomyelia ?
Answer: Surgery is usually recommended for individuals with syringomyelia, with the type of surgery and its location dependent on the type of syrinx. In persons with syringomyelia that is associated with the Chiara I malformation, a procedure that removes skulll bone and expands the space around the malformation usually prevents new symptoms from developing and results in the syrinx becoming smaller. In some individuals it may be necessary to drain the syrinx, which can be accomplished using a catheter, drainage tubes, and valves. Recurrence of syringomyelia after surgery may make additional operations necessary; these may not be completely successful over the long term.
                
In the absence of symptoms, syringomyelia is usually not treated. In addition, a physician may recommend not treating the condition in individuals of advanced age or in cases where there is no progression of symptoms. Whether treated or not, many individuals are told to avoid activities that involve straining.
Question:  What is the outlook for Syringomyelia ?
Answer: Symptoms usually begin in young adulthood, with symptoms of one form usually beginning between the ages of 25 and 40. If not treated surgically (when needed), syringomyelia often leads to progressive weakness in the arms and legs, loss of hand sensation, and chronic, severe pain. Symptoms may worsen with straining or any activity that causes cerebrospinal fluid pressure to fluctuate. Some individuals may have long periods of stability. Surgery results in stabilization or modest improvement in symptoms for most individuals. Delay in treatment may result in irreversible spinal cord injury.
Question:  what research (or clinical trials) is being done for Syringomyelia ?
Answer: The mission of the National Institute of Neurological Disorders and Stroke (NINDS) is to seek fundamental knowledge about the brain and nervous system and to use that knowledge to reduce the burden of neurological disease. NINDS investigators are studying how syrinxes first form, as well as the mechanisms of the disorders. NINDS investigators have found that the normal flow of cerebrospinal fluid that occurs with each heartbeat is obstructed in people with syringomyelia. Surgical procedures that relieve this obstruction usually result in the syrinx becoming much smaller in size. Studies are also underway to identify and better understand genetic factors that influence the development of Chiari I malformations and syringomyelia. Researchers hope to better understand the role of birth defects of the skull and brain in the development of hindbrain malformations that can lead to syringomyelia. Diagnostic technology is another area for continued research. 
                
NINDS scientists are examining individuals who either have syringomyelia or are at risk of developing the disorder. They are investigating the factors that influence its development, progression, and treatment by recording more than 5 years of symptoms, muscle strength, overall function, and magnetic resonance imaging (MRI) scan findings from individuals who receive standard treatment for syringomyelia. Study results may allow scientists to provide more accurate recommendations to future individuals with syringomyelia regarding optimal surgical or non-surgical treatments.
Question:  What is (are) Dandy-Walker Syndrome ?
Answer: Dandy-Walker Syndrome is a congenital brain malformation involving the cerebellum (an area of the back of the brain that coordinates movement) and the fluid-filled spaces around it. The key features of this syndrome are an enlargement of the fourth ventricle (a small channel that allows fluid to flow freely between the upper and lower areas of the brain and spinal cord), a partial or complete absence of the area of the brain between the two cerebellar hemispheres (cerebellar vermis), and cyst formation near the lowest part of the skull. An increase in the size and pressure of the fluid spaces surrounding the brain (hydrocephalus) may also be present. The syndrome can appear dramatically or develop unnoticed. Symptoms, which often occur in early infancy, include slow motor development and progressive enlargement of the skull. In older children, symptoms of increased intracranial pressure (pressure within the skull) such as irritability and vomiting, and signs of cerebellar dysfunction such as unsteadiness, lack of muscle coordination, or jerky movements of the eyes may occur. Other symptoms include increased head circumference, bulging at the back of the skull, abnormal breathing problems, and problems with the nerves that control the eyes, face and neck. Dandy-Walker Syndrome is sometimes associated with disorders of other areas of the central nervous system, including absence of the area made up of nerve fibers connecting the two cerebral hemispheres (corpus callosum) and malformations of the heart, face, limbs, fingers and toes.
Question:  What are the treatments for Dandy-Walker Syndrome ?
Answer: Treatment for individuals with Dandy-Walker Syndrome generally consists of treating the associated problems, if needed. A surgical procedure called a shunt may be required to drain off excess fluid within the brain, which will reduce pressure inside the skull and improve symptoms. Treatment may also include various forms of therapy (physicial, occupational) and specialized education.
Question:  What is the outlook for Dandy-Walker Syndrome ?
Answer: The effect of Dandy-Walker Syndrome on intellectual development is variable, with some children having normal cognition and others never achieving normal intellectual development even when the excess fluid buildup is treated early and correctly. Longevity depends on the severity of the syndrome and associated malformations. The presence of multiple congenital defects may shorten life span.
Question:  what research (or clinical trials) is being done for Dandy-Walker Syndrome ?
Answer: The mission of the National Institute of Neurological Disorders and Stroke (NINDS) is to seek fundamental knowledge about the brain and nervous system, and to use that knowledge to reduce the burden of neurological disease. The NINDS conducts and supports a wide range of studies that explore the complex mechanisms of normal brain development. Researchers are studying DNA samples from individuals with Dandy-Walker syndrome to identify genes involved with the syndrome, as well as to better understand its causes and improve diagnosis and treatment options. Other research indicates that mothers with diabetes and those with rubella (German measles) during pregnancy are more likely to have a child with Dandy-Walker syndrome.
Question:  What is (are) Spina Bifida ?
Answer: Spina bifida (SB) is a neural tube defect (a disorder involving incomplete development of the brain, spinal cord, and/or their protective coverings) caused by the failure of the fetus's spine to close properly during the first month of pregnancy. Infants born with SB sometimes have an open lesion on their spine where significant damage to the nerves and spinal cord has occurred. Although the spinal opening can be surgically repaired shortly after birth, the nerve damage is permanent, resulting in varying degrees of paralysis of the lower limbs. Even when there is no lesion present there may be improperly formed or missing vertebrae and accompanying nerve damage. In addition to physical and mobility difficulties, most individuals have some form of learning disability. The types of SB are: myelomeningocele, the severest form, in which the spinal cord and its protective covering (the meninges) protrude from an opening in the spine; meningocele in which the spinal cord develops normally but the meninges and spinal fluid) protrude from a spinal opening; closed neural tube defects, which consist of a group of defects in which development of the spinal cord is affected by malformations of the fat, bone, or meninges; and and occulta, the mildest form, in which one or more vertebrae are malformed and covered by a layer of skin. SB may also cause bowel and bladder complications, and many children with SB have hydrocephalus (excessive accumulation of cerebrospinal fluid in the brain).
Question:  What are the treatments for Spina Bifida ?
Answer: There is no cure for SB because the nerve tissue cannot be replaced or repaired. Treatment for the variety of effects of SB may include surgery, medication, and physiotherapy. Many individuals with SB will need assistive devices such as braces, crutches, or wheelchairs. Ongoing therapy, medical care, and/or surgical treatments may be necessary to prevent and manage complications throughout the individual's life. Surgery to close the newborn's spinal opening is generally performed within 24 hours after birth to minimize the risk of infection and to preserve existing function in the spinal cord.
Question:  What is the outlook for Spina Bifida ?
Answer: The prognosis for individuals with SB depends on the number and severity of abnormalities. Prognosis is poorest for those with complete paralysis, hydrocephalus, and other congenital defects. With proper care, most children with SB live well into adulthood.
Question:  what research (or clinical trials) is being done for Spina Bifida ?
Answer: The NINDS supports a broad range of research on neural tube defects such as SB aimed at finding ways to treat, prevent, and, ultimately, cure these 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 400 micrograms of folic acid daily.
