Topic: Congenital Myasthenia
Question: What is (are) Congenital Myasthenia ?
Answer: All forms of myasthenia are due to problems in the communication between nerve cells and muscles. Most involve the activities of neurotransmitters. Neurotransmitters are chemicals that allow neurons to relay information from one cell to the next. For neurotransmitters to be effective, the nerve cell must release the neurotransmitter properly, and the muscle cell must be able to detect the neurotransmitter and respond to its signal properly.
                
The most common type of myasthenia, myasthenia gravis, is caused by an abnormal immune response in which antibodies block the ability of the muscle to detect the neurotransmitter. Congenital myasthenia, however, differs from myasthenia gravis because the disrupted communication isn't caused by antibodies, but by genetic defects.
                
There are several different subtypes of congenital myasthenia, each the result of a specific genetic mutation. Since all types of myasthenia are due to the inability of nerves to trigger muscle activity, they all involve weakness, although there is some variability in the specific muscles affected.
                
Symptoms of congenital myasthenia usually appear in the first few years of childhood, but may not be noticeable until much later, occasionally remaining unrecognized until adulthood. If the symptoms begin in infancy, they usually appear as "floppiness" and a failure to meet developmental milestones, such as rolling over or sitting up. Some infants may also have episodes of choking or pauses in breathing. If the symptoms begin in toddlers or preschool children, they appear as weakness during physical activities or an inability to perform age-appropriate actions, such as running or climbing. In addition, if eye muscles are involved, children may have droopy eyelids, "lazy eye," or double vision. If mouth or throat muscles are involved, children may have difficulty speaking or swallowing. An important characteristic of myasthenia is that the weakness worsens during continuous activity, with strength returning, at least partially, after resting.
                
Congenital myasthenia is an inherited (genetic) disorder. All but one known subtype are recessive disorders, which means that a child will have to have two copies of the abnormal gene (one from each parent) in order to develop the disease. To diagnose congenital myasthenia, a neurologist will test various muscles to determine if they grow weaker with repeated activity. The doctor will also test the electrical activity of nerves and muscles using electromyography (EMG) and nerve conduction tests (NCS). Blood tests are often used to determine if antibodies could be causing the symptoms. Genetic tests may be ordered.

Topic: Congenital Myasthenia
Question: What are the treatments for Congenital Myasthenia ?
Answer: The possibilities for treatment depend on the specific subtype of congenital myasthenia. Most treatments attempt to improve the signaling between nerve cell and muscle. These drugs include pyridostigmine, fluoxetine, ephedrine, and 3,4-diaminopyridine. Treatments to alter the immune system are not used for this form of myasthenia. There are no treatments to cure the underlying genetic abnormality.

Topic: Congenital Myasthenia
Question: What is the outlook for Congenital Myasthenia ?
Answer: The prognosis depends on the specific subtype of congenital myasthenia, the muscles involved, and the age at onset of symptoms. If a child has difficulty breathing, feeding, or swallowing, they may be vulnerable to pneumonia or respiratory failure. In other cases, weakness is stable and does not worsen over time. In one subtype, weakness improves with time. Life-span is normal in most cases in which respiratory function is not compromised.

Topic: Neuromyelitis Optica
Question: What is (are) Neuromyelitis Optica ?
Answer: Neuromyelitis optica (NMO) is an autoimmune disease of the central nervous system (CNS) that predominantly affects the optic nerves and spinal cord. It is sometimes also referred to as NMO spectrum disorder.In NMO, the body's immune system mistakenly attacks healthy cells and proteins in the body, must often those in the spinal cord and eyes. Individuals with NMO develop optic neuritis, which caused pain in the eye and vision loss. Individuals also develop transverse myelitis, which causes weakness or paralysis of arms and legs,and numbness, along with loss of bladder and bowel control Magnetic resonance imaging of the spine often shows an abnormality that extends over long segments of the spinal cord. Individuals may also develop episodes of severe nausea and vomiting, with hiccups from involvement of a part of the brain that ocntrols vomiting The disease is caused by abnormal autoantibodies that bind to a protein called aquaporin-4. Binding of the aquaporin-4 antibody activates other components of the immune system, causing inflammation and damage to these cells. This also results in the brain and spinal cord the loss of myelin, the fatty substance that acts as insulation around nerve fibers and helps nerve signals move from cell to cell.
                
NMO is different from multiple sclerosis (MS). Attacks are usually more severe in NMO than in MS, and NMO is treated differently than MS. Most individuals with NMO experience clusters of attacks days to months or years apart, followed by partial recovery during periods of remission. Women are more often affected by NMO than men. African Americans are at greater risk of the disease than are Caucasians. The onset of NMO varies from childhood to adulthood, with two peaks, one in childhood and the other in adults in their 40s.

Topic: Neuromyelitis Optica
Question: What are the treatments for Neuromyelitis Optica ?
Answer: There is no cure for NMO and no FDA-approved therapies, but there are therapies to treat an attack while it is happening, to reduce symptoms, and to prevent relapses.NMO relapses and attacks are often treated with corticosteroid drugs and plasma exchange (also called plasmapheresis, a process used to remove harmful antibodies from the bloodstream). Immunosuppressvie drugs used to prevent attacks include mycophenolate mofetil, rituximab, and azathioprine. Pain, stiffness, muscle spasms, and bladder and bowel control problems can be managed with medicaitons and therapies. Individuals with major disability will require the combined efforts to physical and occupational therapists, along with social services professionals to address complex rehabilitation needs.

Topic: Neuromyelitis Optica
Question: What is the outlook for Neuromyelitis Optica ?
Answer: Most individuals with NMO have an unpredictable, relapsing course of disease with attacks occurring months or years apart. Disability is cumulative, the result of each attack damaging new areas of the central nervous system. Some individuals are severely affected by NMO and can lose vision in both eyes and the use of their arms and legs. Most individuals experience some degree of permanent limb weakness or vision loss from NMO. However, reducing the number of attacks with immunosuppressive medications may help prevent with accumulation of disability. Rarely, muscle weakness can be severe enough to cause breathing difficulties and may require the use of artificial ventilation.

Topic: Neuromyelitis Optica
Question: what research (or clinical trials) is being done for Neuromyelitis Optica ?
Answer: 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 is a component of the National Institutes of Health, the leading supporter of biomedical research in the world. NINDS researchers are working to better understand the process by which the immune system destroys or attacks the nerve insulating substance called myelin in autoijmune diseases or disorders. Other work focuses on strategies to repair demyelinated spinal cords, including approaches using cell transplantation. this research may lead to a grater understanding of the mechanisms responsible for damaging myelin and may ultimately provide a means to prevent and treat transverse myelitis An NINDS-funded study comparing clinical MRI and lumbar puncture of healthy individuals to those with symptoms of immune-related central nervous system damage hopes to identify processes or mechanisms to inhibit or minimize spinal tissue damage and enhance recovery mechanisms. Multiple studies are looking at ways to target different components of the immune system known to be involved in NMO spectrum disorders to allow more directly targeted treatment of this disease.

Topic: Cerebral Hypoxia
Question: What is (are) Cerebral Hypoxia ?
Answer: Cerebral hypoxia refers to a condition in which there is a decrease of oxygen supply to the brain even though there is adequate blood flow. Drowning, strangling, choking, suffocation, cardiac arrest, head trauma, carbon monoxide poisoning, and complications of general anesthesia can create conditions that can lead to cerebral hypoxia. Symptoms of mild cerebral hypoxia include inattentiveness, poor judgment, memory loss, and a decrease in motor coordination. Brain cells are extremely sensitive to oxygen deprivation and can begin to die within five minutes after oxygen supply has been cut off. When hypoxia lasts for longer periods of time, it can cause coma, seizures, and even brain death. In brain death, there is no measurable activity in the brain, although cardiovascular function is preserved. Life support is required for respiration.

Topic: Cerebral Hypoxia
Question: What are the treatments for Cerebral Hypoxia ?
Answer: Treatment depends on the underlying cause of the hypoxia, but basic life-support systems have to be put in place: mechanical ventilation to secure the airway; fluids, blood products, or medications to support blood pressure and heart rate; and medications to suppress seizures.
(Source: NINDS)
Topic: Cerebral Hypoxia
Question: What is the outlook for Cerebral Hypoxia ?
Answer: Recovery depends on how long the brain has been deprived of oxygen and how much brain damage has occurred, although carbon monoxide poisoning can cause brain damage days to weeks after the event. Most people who make a full recovery have only been briefly unconscious. The longer someone is unconscious, the higher the chances of death or brain death and the lower the chances of a meaningful recovery. During recovery, psychological and neurological abnormalities such as amnesia, personality regression, hallucinations, memory loss, and muscle spasms and twitches may appear, persist, and then resolve.

Topic: Essential Tremor
Question: What is (are) Essential Tremor ?
Answer: Tremor is an unintentional, somewhat rhythmic, muscle movement involving to-and-fro movements (oscillations) of one or more parts of the body. Essential tremor (previously called benign essential tremor) is the most common form of abnormal tremor. (In some people, tremor is a symptom of a neurological disorder or appears as a side effect of certain drugs.) Although it may be mild and nonprogressive in some people, in others the tremor is slowly progressive, starting on one side of the body but eventually affecting both sides. Hand tremor is most common but the head, arms, voice, tongue, legs, and trunk may also be involved. Hand tremor may cause problems with purposeful movements such as eating, writing, sewing, or shaving. Head tremor may be seen as a "yes-yes" or "no-no" motion. Essential tremor may be accompanied by mild gait disturbance. Heightened emotion, stress, fever, physical exhaustion, or low blood sugar may trigger tremors or increase their severity. There may be mild degeneration in the certain parts of the cerebellum in persons with essential tremor. Onset is most common after age 40, although symptoms can appear at any age. Children of a parent who has essential tremor have up to a 50 percent chance of inheriting the condition. Essential tremor is not associated with any known pathology.

Topic: Essential Tremor
Question: What are the treatments for Essential Tremor ?
Answer: There is no definitive cure for essential tremor. Symptomatic drug therapy may include propranolol or other beta blockers and primidone, an anticonvulsant drug. Eliminating tremor "triggers" such as caffeine and other stimulants from the diet is often recommended. Physical and occupational therapy may help to reduce tremor and improve coordination and muscle control for some individuals. Deep brain stimulation uses a surgically implanted, battery-operated medical device called a neurostimulator to delivery electrical stimulation to targeted areas of the brain that control movement, temporarily blocking the nerve signals that cause tremor. Other surgical intervention is effective but may have side effects.

Topic: Essential Tremor
Question: What is the outlook for Essential Tremor ?
Answer: Although essential tremor is not life-threatening, it can make it harder to perform daily tasks and is embarrassing to some people. Tremor frequency may decrease as the person ages, but the severity may increase, affecting the person's ability to perform certain tasks or activities of daily living. In many people the tremor may be mild throughout life.

Topic: Essential Tremor
Question: what research (or clinical trials) is being done for Essential Tremor ?
Answer: The National Institute of Neurological Disorders and Stroke, a unit of the National Institutes of Health (NIH) within the U.S. Department of Health and Human Services, is the nation's leading federal funder of research on disorders of the brain and nervous system. The NINDS sponsors research on tremor both at its facilities at the NIH and through grants to medical centers.
                
Scientists at the NINDS are evaluating the effectiveness of 1-octanol, a substance similar to alcohol but less intoxicating, for treating essential tremor. Results of two previous NIH studies have shown this agent to be promising as a potential new treatment.
                
Scientists are also studying the effectiveness of botulinum toxin as a treatment for a variety of involuntary movement disorders, including essential tremor of the hand.

Topic: Paresthesia
Question: What is (are) Paresthesia ?
Answer: Paresthesia refers to a burning or prickling sensation that is usually felt in the hands, arms, legs, or feet, but can also occur in other parts of the body. The sensation, which happens without warning, is usually painless and described as tingling or numbness, skin crawling, or itching.  Most people have experienced temporary paresthesia -- a feeling of "pins and needles" -- at some time in their lives when they have sat with legs crossed for too long, or fallen asleep with an arm crooked under their head. It happens when sustained pressure is placed on a nerve. The feeling quickly goes away once the pressure is relieved.  Chronic paresthesia is often a symptom of an underlying neurological disease or traumatic nerve damage. Paresthesia can be caused by disorders affecting the central nervous system, such as stroke and transient ischemic attacks (mini-strokes), multiple sclerosis, transverse myelitis, and encephalitis. A tumor or vascular lesion pressed up against the brain or spinal cord can also cause paresthesia. Nerve entrapment syndromes, such as carpal tunnel syndrome, can damage peripheral nerves and cause paresthesia accompanied by pain. Diagnostic evaluation is based on determining the underlying condition causing the paresthetic sensations. An individual's medical history, physical examination, and laboratory tests are essential for the diagnosis. Physicians may order additional tests depending on the suspected cause of the paresthesia.

Topic: Microcephaly
Question: What is (are) Microcephaly ?
Answer: 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.

Topic: Microcephaly
Question: What are the treatments for Microcephaly ?
Answer: 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.

Topic: Microcephaly
Question: What is the outlook for Microcephaly ?
Answer: 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.

Question: what research (or clinical trials) is being done for Microcephaly ?
Answer: 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.

Topic: Neuroleptic Malignant Syndrome
Question: What is (are) Neuroleptic Malignant Syndrome ?
Answer: Neuroleptic malignant syndrome is a life-threatening, neurological disorder most often caused by an adverse reaction to neuroleptic or antipsychotic drugs. Symptoms include high fever, sweating, unstable blood pressure, stupor, muscular rigidity, and autonomic dysfunction. In most cases, the disorder develops within the first 2 weeks of treatment with the drug; however, the disorder may develop any time during the therapy period. The syndrome can also occur in people taking anti-Parkinsonism drugs known as dopaminergics if those drugs are discontinued abruptly.

Topic: Neuroleptic Malignant Syndrome
Question: What are the treatments for Neuroleptic Malignant Syndrome ?
Answer: Generally, intensive care is needed. The neuroleptic or antipsychotic drug is discontinued, and the fever is treated aggressively. A muscle relaxant may be prescribed. Dopaminergic drugs, such as a dopamine agonist, have been reported to be useful.
(Source: NINDS)
Topic: Neuroleptic Malignant Syndrome
Question: What is the outlook for Neuroleptic Malignant Syndrome ?
Answer: Early identification of and treatment for individuals with neuroleptic malignant syndrome improves outcome. If clinically indicated, a low potency neuroleptic can be reintroduced very slowly when the individual recovers, although there is a risk that the syndrome might recur. Another alternative is to substitute another class of drugs for the neuroleptic. Anesthesia may be a risk to individuals who have experienced neuroleptic malignant syndrome.
