The knowledge gained from these studies provides the foundation for understanding abnormal development and offers hope for new ways to treat and prevent NMDs. </s></s>

<s>[INST] What is (are) Autism ? [/INST] Autistic disorder (sometimes called autism or classical ASD) is the most common condition in a group of developmental disorders known as the autism spectrum disorders (ASDs). Autistic children have difficulties with social interaction, display problems with verbal and nonverbal communication, and exhibit repetitive behaviors or narrow, obsessive interests. These behaviors can range in impact from mild to disabling. Autism varies widely in its severity and symptoms and may go unrecognized, especially in mildly affected children or when more debilitating handicaps mask it. Scientists arent certain what causes autism, but its likely that both genetics and environment play a role. </s></s>

<s>[INST] What are the treatments for Autism ? [/INST] There is no cure for autism. Therapies and behavioral interventions are designed to remedy specific symptoms and can bring about substantial improvement. The ideal treatment plan coordinates therapies and interventions that meet the specific needs of individual children. Treatment options include educational/bahavioral interventions, medications, and other therapies. Most professionals agree that the earlier the intervention, the better. </s></s>

<s>[INST] What is the outlook for Autism ? [/INST] For many children, autism symptoms improve with treatment and with age. Some children with autism grow up to lead normal or near-normal lives. Children whose language skills regress early in life, usually before the age of 3, appear to be at risk of developing epilepsy or seizure-like brain activity. During adolescence, some children with autism may become depressed or experience behavioral problems. Parents of these children should be ready to adjust treatment for their child as needed. People with an ASD usually continue to need services and support as they get older but many are able to work successfully and live independently or within a supportive environment. </s></s>

<s>[INST] What is (are) Meningitis and Encephalitis ? [/INST] Meningitis is an infection of the meninges, the membranes that surround the brain and spinal cord. Encephalitis is inflammation of the brain itself. Causes of encephalitis and meningitis include viruses, bacteria, fungus, and parasites. Anyone can get encephalitis or meningitis.Inflammation from encephalitis and meningitis produce a wide range of symptoms. Symptoms of encephalitis include sudden fever, headache, vomiting, heightened sensitivity to light, stiff neck and back, confusion and impaired judgment, drowsiness, weak muscles, a clumsy and unsteady gait, and irritability. In more severe cases, people may have problems with speech or hearing, vision problems, and hallucinations. Symptoms that might require emergency treatment include loss of consciousness, seizures, muscle weakness, or sudden severe dementia. Symptoms of meningitis, which may appear suddenly, often include high fever, severe and persistent headache, stiff neck, nausea, sensitivity to bright light, and vomiting. Changes in behavior such as confusion, sleepiness, and difficulty waking up may also occur. In infants, symptoms of meningitis or encephalitis may include fever, vomiting, lethargy, body stiffness, unexplained irritability, and a full or bulging fontanel (the soft spot on the top of the head). Anyone experiencing symptoms of meningitis or encephalitis should see a doctor immediately. </s></s>

<s>[INST] What are the treatments for Meningitis and Encephalitis ? [/INST] Anyone experiencing symptoms of meningitis or encephalitis should see a doctor immediately. Antibiotics for most types of meningitis can greatly reduce the risk of dying from the disease. Antiviral medications may be prescribed for viral encephalitis or other severe viral infections.Anticonvulsants are used to prevent or treat seizures. Corticosteroidd rugs can reduce brain swelling and inflammation. Over-the-counter medications may be used for fever and headache. Individuals with encephalitis or bacterial meningitis are usually hospitalized for treatment. Affected individuals with breathing difficulties may require artificial respiration. </s></s>

<s>[INST] What is the outlook for Meningitis and Encephalitis ? [/INST] The prognosis for for people with encephalitis or meningitis varies. Some cases are mild, short and relatively benign and individuals have full recovery, although the process may be slow. Individuals who experience mild symptoms may recover in 2-4 weeks. Other cases are severe, and permanent impairment or death is possible. The acute phase of encephalitis may last for 1 to 2 weeks, with gradual or sudden resolution of fever and neurological symptoms. Individuals treated for bacterial meningitis typically show some relief within 48-72 hours. Neurological symptoms may require many months before full recovery. With early diagnosis and prompt treatment, most individuals recover from meningitis. However, in some cases, the disease progresses so rapidly that death occurs during the first 48 hours, despite early treatment. </s></s>

<s>[INST] what research (or clinical trials) is being done for Meningitis and Encephalitis ? [/INST] 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 is a component of the National Institutes of Health, the leading supporter of biomedical research in the world. Current research efforts include gaining a better understanding of how the central nervous system responds to inflammation in the brain, as well as to better understand the molecular mechanisms involved in the protection and disruption of the blood-brain barrier, which could lead to the development of new treatments for several neuroinflammatory diseases such as meningitis and encephalitis. </s></s>

<s>[INST] What is (are) SUNCT Headache ? [/INST] SUNCT-Short-lasting, Unilateral, Neuralgiform headache attacks with Conjunctival injection and Tearing-is a rare form of headache that is most common in men after age 50. The disorder is marked by bursts of moderate to severe burning, piercing, or throbbing pain, usually on one side of the head and around the eye or temple. The pain usually peaks within seconds of onset and may follow a pattern of increasing and decreasing intensity. Attacks typically occur in daytime hours and last from 5 seconds to 4 minutes per episode. Individuals generally have five to six attacks per hour. Autonomic nervous system responses include watery eyes, reddish or bloodshot eyes caused by dilation of blood vessels (conjunctival injection), nasal congestion, runny nose, sweaty forehead, swelling of the eyelids, and increased pressure within the eye on the affected side of head. Systolic blood pressure may rise during the attacks. Movement of the neck may trigger these headaches. SUNCT may be a form of trigeminal neuralgia and is considered one of the trigeminal autonomic cephalgias, or TACs. </s></s>

<s>[INST] What are the treatments for SUNCT Headache ? [/INST] These headaches are generally non-responsive to usual treatment for other short-lasting headaches. Corticosteroids and the anti-epileptic drugs gabapentin, lamotrigine, and carbamazepine may help relieve some symptoms in some patients. Studies have shown that injections of glycerol to block nerve signaling along the trigeminal nerve may provide temporary relief in some severe cases, but the headaches recurred in about 40 percent of individuals studied. </s></s>

<s>[INST] What is (are) Dyslexia ? [/INST] Dyslexia is a brain-based type of learning disability that specifically impairs a person's ability to read. These individuals typically read at levels significantly lower than expected despite having normal intelligence. Although the disorder varies from person to person, common characteristics among people with dyslexia are difficulty with phonological processing (the manipulation of sounds), spelling, and/or rapid visual-verbal responding. In individuals with adult onset of dyslexia, it usually occurs as a result of brain injury or in the context of dementia; this contrasts with individuals with dyslexia who simply were never identified as children or adolescents. Dyslexia can be inherited in some families, and recent studies have identified a number of genes that may predispose an individual to developing dyslexia. </s></s>

<s>[INST] What are the treatments for Dyslexia ? [/INST] The main focus of treatment should be on the specific learning problems of affected individuals. The usual course is to modify teaching methods and the educational environment to meet the specific needs of the individual with dyslexia. </s></s>

<s>[INST] What is the outlook for Dyslexia ? [/INST] For those with dyslexia, the prognosis is mixed. The disability affects such a wide range of people and produces such different symptoms and varying degrees of severity that predictions are hard to make. The prognosis is generally good, however, for individuals whose dyslexia is identified early, who have supportive family and friends and a strong self-image, and who are involved in a proper remediation program. </s></s>

<s>[INST] What is (are) Aphasia ? [/INST] Aphasia is a neurological disorder caused by damage to the portions of the brain that are responsible for language production or processing. It may occur suddenly or progressively, depending on the type and location of brain tissue involved. Primary signs of the disorder include difficulty in expressing oneself when speaking, trouble understanding speech, and difficulty with reading and writing. Aphasia is not a disease, but a symptom of brain damage. Although it is primarily seen in individuals who have suffered a stroke, aphasia can also result from a brain tumor, infection, inflammation, head injury, or dementia that affect language-associated regions of the brain. It is estimated that about 1 million people in the United States today suffer from aphasia. The type and severity of language dysfunction depends on the precise location and extent of the damaged brain tissue. Generally, aphasia can be divided into four broad categories: (1) Expressive aphasia (also called Broca's aphasia) involves difficulty in conveying thoughts through speech or writing. The person knows what she/he wants to say, but cannot find the words he needs. (2) Receptive aphasia (Wernicke's aphasia) involves difficulty understanding spoken or written language. The individual hears the voice or sees the print but cannot make sense of the words. (3) Global aphasia results from severe and extensive damage to the language areas of the brain. People lose almost all language function, both comprehension and expression. They cannot speak or understand speech, nor can they read or write. (4) Indiivfduals with anomic or amnesia aphasia, the least severe form of aphasia, have difficulty in using the correct names for particular objects, people, places, or events. </s></s>

<s>[INST] What are the treatments for Aphasia ? [/INST] In some instances, an individual will completely recover from aphasia without treatment. In most cases, however, language therapy should begin as soon as possible and be tailored to the individual needs of the person. Rehabilitation with a speech pathologist involves extensive exercises in which individuals read, write, follow directions, and repeat what they hear. Computer-aided therapy may supplement standard language therapy. </s></s>

<s>[INST] What is the outlook for Aphasia ? [/INST] The outcome of aphasia is difficult to predict given the wide range of variability of the condition. Generally, people who are younger or have less extensive brain damage fare better. The location of the injury is also important and is another clue to prognosis. In general, people tend to recover skills in language comprehension more completely than those skills involving expression. </s></s>

<s>[INST] what research (or clinical trials) is being done for Aphasia ? [/INST] The National Institute of Neurological Disorders and Stroke and the National Institute on Deafness and Other Communication Disorders conduct and support a broad range of scientific investigations to increase our understanding of aphasia, find better treatments, and discover improved methods to restore lost function to people who have aphasia. </s></s>

<s>[INST] What is (are) Colpocephaly ? [/INST] Colpocephaly is a congenital brain abnormality in which the occipital horns - the posterior or rear portion of the lateral ventricles (cavities) of the brain -- are larger than normal because white matter in the posterior cerebrum has failed to develop or thicken. Colpocephaly, one of a group of structural brain disorders known as cephalic disorders, is characterized by microcephaly (an abnormally small head) and impaired intellect. Other features may include movement abnormalities, muscle spasms, and seizures. Although the cause of colpocephaly is unknown, researchers believe that the disorder results from some kind of disturbance in the fetal environment that occurs between the second and sixth months of pregnancy. Colpocephaly may be diagnosed late in pregnancy, although it is often misdiagnosed as hydrocephalus (excessive accumulation of cerebrospinal fluid in the brain). It may be more accurately diagnosed after birth when signs of impaired intellect, microcephaly, and seizures are present. </s></s>

<s>[INST] What are the treatments for Colpocephaly ? [/INST] There is no definitive treatment for colpocephaly. Anticonvulsant medications are often prescribed to prevent seizures, and doctors rely on exercise therapies and orthopedic appliances to reduce shrinkage or shortening of muscles. </s></s>

<s>[INST] What is the outlook for Colpocephaly ? [/INST] The prognosis for individuals with colpocephaly depends on the severity of the associated conditions and the degree of abnormal brain development. Some children benefit from special education. </s></s>

<s>[INST] What is (are) Benign Essential Blepharospasm ? [/INST] Benign essential blepharospasm (BEB) is a progressive neurological disorder characterized by involuntary muscle contractions and spasms of the eyelid muscles. It is a form of dystonia, a movement disorder in which muscle contractions cause sustained eyelid closure, twitching or repetitive movements. BEB begins gradually with increased frequency of eye blinking often associated with eye irritation. Other symptoms may include increasing difficulty in keeping the eyes open, and light sensitivity. Generally, the spasms occur during the day, disappear in sleep, and reappear after waking. As the condition progresses, the spasms may intensify, forcing the eyelids to remain closed for long periods of time, and thereby causing substantial visual disturbance or functional blindness. It is important to note that the blindness is caused solely by the uncontrollable closing of the eyelids and not by a dysfunction of the eyes. BEB occurs in both men and women, although it is especially common in middle-aged and elderly women. </s></s>

<s>[INST] What are the treatments for Benign Essential Blepharospasm ? [/INST] In most cases of BEB the treatment of choice is botulinum toxin injections which relax the muscles and stop the spasms. Other treatment options include medications (drug therapy) or surgery--either local surgery of the eye muscles or deep brain stimulation surgery. </s></s>

<s>[INST] What is the outlook for Benign Essential Blepharospasm ? [/INST] With botulinum toxin treatment most individuals with BEB have substantial relief of symptoms. Although some may experience side effects such as drooping eyelids, blurred or double vision, and eye dryness, these side effects are usually only temporary. The condition may worsen or expand to surrounding muscles; remain the same for many years; and, in rare cases, improve spontaneously. </s></s>

<s>[INST] what research (or clinical trials) is being done for Benign Essential Blepharospasm ?

Much of this research is aimed at increasing understanding of these disorders and finding ways to prevent, treat, and cure them. </s></s>

<s>[INST] What is (are) Traumatic Brain Injury ? [/INST] Traumatic brain injury (TBI), a form ofacquired brain injury, occurs when a sudden trauma causes damage to the brain. TBI can result when the head suddenly and violently hits an object, or when an object pierces the skull and enters brain tissue.Symptoms of a TBI can be mild, moderate, or severe, depending on the extent of the damage to the brain. A person with a mild TBI may remain conscious or may experience a loss of consciousness for a few seconds or minutes. Other symptoms of mild TBI include headache, confusion, lightheadedness, dizziness, blurred vision or tired eyes, ringing in the ears, bad taste in the mouth, fatigue or lethargy, a change in sleep patterns, behavioral or mood changes, and trouble with memory, concentration, attention, or thinking. A person with a moderate or severe TBI may show these same symptoms, but may also have a headache that gets worse or does not go away, repeated vomiting or nausea, convulsions or seizures, an inability to awaken from sleep, dilation of one or both pupils of the eyes, slurred speech, weakness or numbness in the extremities, loss of coordination, and increased confusion, restlessness, or agitation. </s></s>

<s>[INST] What are the treatments for Traumatic Brain Injury ? [/INST] Anyone with signs of moderate or severe TBI should receive medical attention as soon as possible. Because little can be done to reverse the initial brain damage caused by trauma, medical personnel try to stabilize an individual with TBI and focus on preventing further injury. Primary concerns include insuring proper oxygen supply to the brain and the rest of the body, maintaining adequate blood flow, and controlling blood pressure. Imaging tests help in determining the diagnosis and prognosis of a TBI patient. Patients with mild to moderate injuries may receive skull and neck X-rays to check for bone fractures or spinal instability. For moderate to severe cases, the imaging test is a computed tomography (CT) scan. Moderately to severely injured patients receive rehabilitation that involves individually tailored treatment programs in the areas of physical therapy, occupational therapy, speech/language therapy, physiatry (physical medicine), psychology/psychiatry, and social support. </s></s>

<s>[INST] What is the outlook for Traumatic Brain Injury ? [/INST] Approximately half of severely head-injured patients will need surgery to remove or repair hematomas (ruptured blood vessels) or contusions (bruised brain tissue). Disabilities resulting from a TBI depend upon the severity of the injury, the location of the injury, and the age and general health of the individual. Some common disabilities include problems with cognition (thinking, memory, and reasoning), sensory processing (sight, hearing, touch, taste, and smell), communication (expression and understanding), and behavior or mental health (depression, anxiety, personality changes, aggression, acting out, and social inappropriateness). More serious head injuries may result in stupor, an unresponsive state, but one in which an individual can be aroused briefly by a strong stimulus, such as sharp pain; coma, a state in which an individual is totally unconscious, unresponsive, unaware, and unarousable; vegetative state, in which an individual is unconscious and unaware of his or her surroundings, but continues to have a sleep-wake cycle and periods of alertness; and a persistent vegetative state (PVS), in which an individual stays in a vegetative state for more than a month. </s></s>

<s>[INST] what research (or clinical trials) is being done for Traumatic Brain Injury ? [/INST] The National Institute of Neurological Disorders and Stroke (NINDS) supports TBI research through grants to major medical institutions across the country and conducts TBI research in its intramural laboratories and Clinical Center at the National Institutes of Health (NIH) in Bethesda,Maryland. The Center for Neuroscience and Regenerative Medicine (CNRM) is a TBI research collaboration between intramural NIH and the Uniformed Services University for the Health Sciences (USUHS). NINDS-funded research involves studies in the laboratory and in clinical settings to better understand TBI and the biological mechanisms underlying damage to the brain. This research will allow scientists to develop strategies and interventions to limit the primary and secondary brain damage that occurs within days of a head trauma, and to devise therapies to treat brain injury and improve long-term recovery of function.

<s>[INST] What is (are) Polymyositis ? [/INST] Polymyositis is one of a group of muscle diseases known as the inflammatory myopathies, which are characterized by chronic muscle inflammation accompanied by muscle weakness. Polymyositis affects skeletal muscles (those involved with making movement) on both sides of the body. It is rarely seen in persons under age 18; most cases are in adults between the ages of 31 and 60. Progressive muscle weakness starts in the proximal muscles (muscles closest to the trunk of the body) which eventually leads to difficulties climbing stairs, rising from a seated position, lifting objects, or reaching overhead. People with polymyositis may also experience arthritis, shortness of breath, difficulty swallowing and speaking, and heart arrhythmias. In some cases of polymyositis, distal muscles (muscles further away from the trunk of the body, such as those in the forearms and around the ankles and wrists) may be affected as the disease progresses. Polymyositis may be associated with collagen-vascular or autoimmune diseases, such as lupus. Polymyositis may also be associated with infectious disorders, such as HIV-AIDS. </s></s>

<s>[INST] What are the treatments for Polymyositis ? [/INST] There is no cure for polymyositis, but the symptoms can be treated. Options include medication, physical therapy, exercise, heat therapy (including microwave and ultrasound), orthotics and assistive devices, and rest. The standard treatment for polymyositis is a corticosteroid drug, given either in pill form or intravenously. Immunosuppressant drugs, such as azathioprine and methotrexate, may reduce inflammation in people who do not respond well to prednisone. Periodic treatment using intravenous immunoglobulin can also improve recovery. Other immunosuppressive agents used to treat the inflammation associated with polymyositis include cyclosporine A, cyclophosphamide, and tacrolimus. Physical therapy is usually recommended to prevent muscle atrophy and to regain muscle strength and range of motion. </s></s>

<s>[INST] What is the outlook for Polymyositis ? [/INST] The prognosis for polymyositis varies. Most people respond fairly well to therapy, but some have a more severe disease that does not respond adequately to therapies and are left with significant disability. In rare cases individuals with severe and progressive muscle weakness will develop respiratory failure or pneumonia. Difficulty swallowing may cause weight loss and malnutrition. </s></s>

<s>[INST] What is (are) Wallenberg's Syndrome ? [/INST] Wallenbergs syndrome is a neurological condition caused by a stroke in the vertebral or posterior inferior cerebellar artery of the brain stem. Symptoms include difficulties with swallowing, hoarseness, dizziness, nausea and vomiting, rapid involuntary movements of the eyes (nystagmus), and problems with balance and gait coordination. Some individuals will experience a lack of pain and temperature sensation on only one side of the face, or a pattern of symptoms on opposite sides of the body such as paralysis or numbness in the right side of the face, with weak or numb limbs on the left side. Uncontrollable hiccups may also occur, and some individuals will lose their sense of taste on one side of the tongue, while preserving taste sensations on the other side. Some people with Wallenbergs syndrome report that the world seems to be tilted in an unsettling way, which makes it difficult to keep their balance when they walk. </s></s>

<s>[INST] What are the treatments for Wallenberg's Syndrome ? [/INST] Treatment for Wallenberg's syndrome is symptomatic. A feeding tube may be necessary if swallowing is very difficult.

<s>[INST] What is (are) Monomelic Amyotrophy ? [/INST] Monomelic amyotrophy (MMA) is characterized by progressive degeneration and loss of motor neurons, the nerve cells in the brain and spinal cord that are responsible for controlling voluntary muscles. It is characterized by weakness and wasting in a single limb, usually an arm and hand rather than a foot and leg. There is no pain associated with MMA. While some physicians contend that mild sensory loss may be associated with this disease, many experts suggest that such symptoms actually indicate a cause other than MMA. MMA occurs in males between the ages of 15 and 25. Onset and progression are slow. MMA is seen most frequently in Asia, particularly in Japan and India; it is much less common in North America. In most cases, the cause is unknown, although there have been a few published reports linking MMA to traumatic or radiation injury. There are also familial forms of MMA. Diagnosis is made by physical exam and medical history. Electromyography (EMG), a special recording technique that detects electrical activity in muscles, shows a loss of the nerve supply, or denervation, in the affected limb; MRI and CT scans may show muscle atrophy. People believed to have MMA should be followed by a neuromuscular disease specialist for a number of months to make certain that no signs of other motor neuron diseases develop. </s></s>

<s>[INST] What is (are) Gerstmann's Syndrome ? [/INST] Gerstmann's syndrome is a cognitive impairment that results from damage to a specific area of the brain -- the left parietal lobe in the region of the angular gyrus. It may occur after a stroke or in association with damage to the parietal lobe. It is characterized by four primary symptoms: a writing disability (agraphia or dysgraphia), a lack of understanding of the rules for calculation or arithmetic (acalculia or dyscalculia), an inability to distinguish right from left, and an inability to identify fingers (finger agnosia). The disorder should not be confused with Gerstmann-Strussler-Scheinker disease, a type of transmissible spongiform encephalopathy. In addition to exhibiting the above symptoms, many adults also experience aphasia, (difficulty in expressing oneself when speaking, in understanding speech, or in reading and writing). There are few reports of the syndrome, sometimes called developmental Gerstmann's syndrome, in children. The cause is not known. Most cases are identified when children reach school age, a time when they are challenged with writing and math exercises. Generally, children with the disorder exhibit poor handwriting and spelling skills, and difficulty with math functions, including adding, subtracting, multiplying, and dividing. An inability to differentiate right from left and to discriminate among individual fingers may also be apparent. In addition to the four primary symptoms, many children also suffer from constructional apraxia, an inability to copy simple drawings. Frequently, there is also an impairment in reading. Children with a high level of intellectual functioning as well as those with brain damage may be affected with the disorder. </s></s>

<s>[INST] What is (are) Isaacs' Syndrome ? [/INST] Issacs' syndrome (also known as neuromyotonia, Isaacs-Mertens syndrome, continuous muscle fiber activity syndrome, and quantal squander syndrome) is a rare neuromuscular disorder caused by hyperexcitability and continuous firing of the peripheral nerve axons that activate muscle fibers. Symptoms, which include progressive muscle stiffness, continuously contracting or twitching muscles (myokymia), cramping, increased sweating, and delayed muscle relaxation, occur even during sleep or when individuals are under general anesthesia. Many people also develop weakened reflexes and muscle pain, but numbness is relatively uncommon. In most people with Issacs' syndrome, stiffness is most prominent in limb and trunk muscles, although symptoms can be limited to cranial muscles. Speech and breathing may be affected if pharyngeal or laryngeal muscles are involved. Onset is between ages 15 and 60, with most individuals experiencing symptoms before age 40. There are hereditary and acquired (occurring from unknown causes) forms of the disorder. The acquired form occasionally develops in association with peripheral neuropathies or after radiation treatment, but more often is caused by an autoimmune condition. Autoimmune-mediated Issacs' syndrome is typically caused by antibodies that bind to potassium channels on the motor nerve. Issacs' syndrome is only one of several neurological conditions that can be caused by potassium channel antibodies. </s></s>

<s>[INST] What is (are) Spasticity ? [/INST] Spasticity is a condition in which there is an abnormal increase in muscle tone or stiffness of muscle, which might interfere with movement, speech, or be associated with discomfort or pain. Spasticity is usually caused by damage to nerve pathways within the brain or spinal cord that control muscle movement. It may occur in association with spinal cord injury, multiple sclerosis, cerebral palsy, stroke, brain or head trauma, amyotrophic lateral sclerosis, hereditary spastic paraplegias, and metabolic diseases such as adrenoleukodystrophy, phenylketonuria, and Krabbe disease. Symptoms may include hypertonicity (increased muscle tone), clonus (a series of rapid muscle contractions), exaggerated deep tendon reflexes, muscle spasms, scissoring (involuntary crossing of the legs), and fixed joints (contractures). The degree of spasticity varies from mild muscle stiffness to severe, painful, and uncontrollable muscle spasms. Spasticity can interfere with rehabilitation in patients with certain disorders, and often interferes with daily activities. </s></s>

<s>[INST] What are the treatments for Spasticity ? [/INST] Treatment may include such medications as baclofen, diazepam, tizanidine or clonazepam. Physical therapy regimens may include muscle stretching and range of motion exercises to help prevent shrinkage or shortening of muscles and to reduce the severity of symptoms. Targeted injection of botulinum toxin into muscles with the most tome can help to selectively weaken these muscles to improve range of motion and function. Surgery may be recommended for tendon release or to sever the nerve-muscle pathway. </s></s>

<s>[INST] What is (are) Prosopagnosia ? [/INST] Prosopagnosia is a neurological disorder characterized by the inability to recognize faces. Prosopagnosia is also known as face blindness or facial agnosia. The term prosopagnosia comes from the Greek words for face and lack of knowledge. Depending upon the degree of impairment, some people with prosopagnosia may only have difficulty recognizing a familiar face; others will be unable to discriminate between unknown faces, while still others may not even be able to distinguish a face as being different from an object. Some people with the disorder are unable to recognize their own face. Prosopagnosia is not related to memory dysfunction, memory loss, impaired vision, or learning disabilities. Prosopagnosia is thought to be the result of abnormalities, damage, or impairment in the right fusiform gyrus, a fold in the brain that appears to coordinate the neural systems that control facial perception and memory. Prosopagnosia can result from stroke, traumatic brain injury, or certain neurodegenerative diseases. In some cases it is a congenital disorder, present at birth in the absence of any brain damage. Congenital prosopagnosia appears to run in families, which makes it likely to be the result of a genetic mutation or deletion. Some degree of prosopagnosia is often present in children with autism and Aspergers syndrome, and may be the cause of their impaired social development. </s></s>

<s>[INST] What are the treatments for Prosopagnosia ? [/INST] The focus of any treatment should be to help the individual with prosopagnosia develop compensatory strategies. Adults who have the condition as a result of stroke or brain trauma can be retrained to use other clues to identify individuals. </s></s>

<s>[INST] What is the outlook for Prosopagnosia ? [/INST] Prosopagnosia can be socially crippling. Individuals with the disorder often have difficulty recognizing family members and close friends. They often use other ways to identify people, such as relying on voice, clothing, or unique physical attributes, but these are not as effective as recognizing a face. Children with congenital prosopagnosia are born with the disability and have never had a time when they could recognize faces. Greater awareness of autism, and the autism spectrum disorders, which involve communication impairments such as prosopagnosia, is likely to make the disorder less overlooked in the future. </s></s>

<s>[INST] What is (are) Lesch-Nyhan Syndrome ? [/INST] Lesch-Nyhan syndrome (LNS) is a rare, inherited disorder caused by a deficiency of the enzyme hypoxanthine-guanine phosphoribosyltransferase (HPRT). LNS is an X-linked recessive disease-- the gene is carried by the mother and passed on to her son. LNS is present at birth in baby boys. The lack of HPRT causes a build-up of uric acid in all body fluids, and leads to symptoms such as severe gout, poor muscle control, and moderate retardation, which appear in the first year of life. A striking feature of LNS is self-mutilating behaviors characterized by lip and finger biting that begin in the second year of life. Abnormally high uric acid levels can cause sodium urate crystals to form in the joints, kidneys, central nervous system, and other tissues of the body, leading to gout-like swelling in the joints and severe kidney problems. Neurological symptoms include facial grimacing, involuntary writhing, and repetitive movements of the arms and legs similar to those seen in Huntingtons disease. Because a lack of HPRT causes the body to poorly utilize vitamin B12, some boys may develop a rare disorder called megaloblastic anemia. </s></s>

<s>[INST] What are the treatments for Lesch-Nyhan Syndrome ? [/INST] Treatment for LNS is symptomatic. Gout can be treated with allopurinol to control excessive amounts of uric acid. Kidney stones may be treated with lithotripsy, a technique for breaking up kidney stones using shock waves or laser beams. There is no standard treatment for the neurological symptoms of LNS. Some may be relieved with the drugs carbidopa/levodopa, diazepam, phenobarbital, or haloperidol. </s></s>

<s>[INST] What is (are) Deep Brain Stimulation for Parkinson's Disease ? [/INST] Deep brain stimulation (DBS) is a surgical procedure used to treat several disabling neurological symptomsmost commonly the debilitating motor symptoms of Parkinsons disease (PD), such as tremor, rigidity, stiffness, slowed movement, and walking problems. The procedure is also used to treat essential tremor and dystonia. At present, the procedure is used only for individuals whose symptoms cannot be adequately controlled with medications. However, only individuals who improve to some degree after taking medication for Parkinsons benefit from DBS. A variety of conditions may mimic PD but do not respond to medications or DBS. DBS uses a surgically implanted, battery-operated medical device called an implantable pulse generator (IPG) - similar to a heart pacemaker and approximately the size of a stopwatch to - deliver electrical stimulation to specific areas in the brain that control movement, thus blocking the abnormal nerve signals that cause PD symptoms. Before the procedure, a neurosurgeon uses magnetic resonance imaging (MRI) or computed tomography (CT) scanning to identify and locate the exact target within the brain for surgical intervention. Some surgeons may use microelectrode recording - which involves a small wire that monitors the activity of nerve cells in the target area - to more specifically identify the precise brain area that will be stimulated. Generally, these areas are the thalamus, subthalamic nucleus, and globus pallidus. There is a low chance that placement of the stimulator may cause bleeding or infection in the brain. The DBS system consists of three components: the lead, the extension, and the IPG. The lead (also called an electrode)a thin, insulated wireis inserted through a small opening in the skull and implanted in the brain. The tip of the electrode is positioned within the specific brain area. The extension is an insulated wire that is passed under the skin of the head, neck, and shoulder, connecting the lead to the implantable pulse generator. The IPG (the "battery pack") is the third component and is usually implanted under the skin near the collarbone. In some cases it may be implanted lower in the chest or under the skin over the abdomen. Once the system is in place, electrical impulses are sent from the IPG up along the extension wire and the lead and into the brain. These impulses block abnormal electrical signals and alleviate PD motor symptoms. </s></s>

<s>[INST] What are the treatments for Deep Brain Stimulation for Parkinson's Disease ? [/INST] Unlike previous surgeries for PD, DBS involves minimal permanent surgical changes to the brain. Instead, the procedure uses electrical stimulation to regulate electrical signals in neural circuits to and from identified areas in the brain to improve PD symptoms. Thus, if DBS causes unwanted side effects or newer, more promising treatments develop in the future, the implantable pulse generator can be removed, and the DBS procedure can be halted. Also, stimulation from the IPG is easily adjustablewithout further surgeryif the persons condition changes. Some people describe the pulse generator adjustments as "programming." </s></s>

<s>[INST] What is the outlook for Deep Brain Stimulation for Parkinson's Disease ? [/INST] Although most individuals still need to take medication after undergoing DBS, many people with Parkinsons disease experience considerable reduction of their motor symptoms and are able to reduce their medications. The amount of reduction varies but can be considerably reduced in most individuals, and can lead to a significant improvement in side effects such as dyskinesias (involuntary movements caused by long-term use of levodopa). In some cases, the stimulation itself can suppress dyskinesias without a reduction in medication. DBS does not improve cognitive symptoms in PD and indeed may worsen them, so it is not generally used if there are signs of dementia. DBS changes the brain firing pattern but does not slow the progression of the neurodegeneration. </s></s>

<s>[INST] what research (or clinical trials) is being done for Deep Brain Stimulation for Parkinson's Disease ? [/INST] The National Institute of Neurological Disorders and Stroke (NINDS), a part of the National institutes of Health (NIH), supports research on DBS to determine its safety, reliability, and effectiveness as a treatment for PD. NINDS supported research on brain circuitry was critical to the development of DBS. Researchers are continuing to study DBS and to develop ways of improving it. A two-part study funded by the NINDS and the Department of Veterans Affairs first compared bilateral DBS to best medical therapy, including medication adjustment and physical therapy. Bilateral DBS showed overall superiority to best medical therapy at improving motor symptoms and quality of life. The second part of the study, involving nearly 300 patients, compared subthalamic nucleus (STN) DBS to globus pallidus interna (GPI) DBS. The two groups reported similar improvements in motor control and quality of life in scores on the Unified Parkinsons Disease Rating Scale. On a variety of neuropsychological tests, there were no significant differences between the two groups. However, the STN DBS group experienced a greater decline on a test of visuomotor processing speed, which measures how quickly someone thinks and acts on information. Also, the STN DBS group had slight worsening on a standard assessment of depression, while the GPI DBS group had slight improvement on the same test. The importance of these two differences is not clear, and will be scrutinized in follow-up research. In addition, NINDS-supported researchers are developing and testing improved implantable pulse generators, and conducting studies to better understand the therapeutic effect of neurostimulation on neural circuitry and brain regions affected in PD.

<s>[INST] What is (are) Lambert-Eaton Myasthenic Syndrome ? [/INST] Lambert-Eaton myasthenic syndrome (LEMS) is a disorder of the neuromuscular junction-the site where nerve cells meet muscle cells and help activate the muscles. It is caused by a disruption of electrical impulses between these nerve and muscle cells. LEMS is an autoimmune condition; in such disorders the immune system, which normally protects the body from foreign organisms, mistakenly attacks the body's own tissues. The disruption of electrical impulses is associated with antibodies produced as a consequence of this autoimmunity. Symptoms include muscle weakness, a tingling sensation in the affected areas, fatigue, and dry mouth. LEMS is closely associated with cancer, in particular small cell lung cancer. More than half the individuals diagnosed with LEMS also develop small cell lung cancer. LEMS may appear up to 3 years before cancer is diagnosed. </s></s>

<s>[INST] What are the treatments for Lambert-Eaton Myasthenic Syndrome ? [/INST] There is no cure for LEMS.

<s>[INST] What is (are) Swallowing Disorders ? [/INST] Having trouble swallowing (dysphagia) is a symptom that accompanies a number of neurological disorders. The problem can occur at any stage of the normal swallowing process as food and liquid move from the mouth, down the back of the throat, through the esophagus and into the stomach. Difficulties can range from a total inability to swallow, to coughing or choking because the food or liquid is entering the windpipe, which is referred to as aspiration. When aspiration is frequent a person can be at risk of developing pneumonia. Food may get "stuck" in the throat or individuals may drool because they cannot swallow their saliva. Neurological conditions that can cause swallowing difficulties are: stroke (the most common cause of dysphagia); traumatic brain injury; cerebral palsy; Parkinson disease and other degenerative neurological disorders such as amyotrophic lateral sclerosis (ALS, also known as Lou Gehrig's disease), multiple sclerosis, progressive supranuclear palsy, Huntington disease, and myasthenia gravis. Muscular dystrophy and myotonic dystrophy are accompanied by dysphagia, which is also the cardinal symptom of oculopharyngeal muscular dystrophy, a rare, progressive genetic disorder. </s></s>

<s>[INST] What are the treatments for Swallowing Disorders ? [/INST] Changing a person's diet by adding thickeners helps many people, as does learning different ways to eat and chew that reduce the risk for aspiration. Occasionally drug therapy that helps the neurological disorder can also help dysphagia. In a few persons, botulinum toxin injections can help when food or liquid cannot enter the esophagus to get to the stomach. More severely disabled individuals may require surgery or the insertion of feeding tubes. </s></s>

<s>[INST] What is the outlook for Swallowing Disorders ? [/INST] The prognosis depends upon the type of swallowing problem and the course of the neurological disorder that produces it. In some cases, dysphagia can be partially or completely corrected using diet manipulation or non-invasive methods.

<s>[INST] What is (are) Post-Polio Syndrome ? [/INST] Post-polio syndrome (PPS) is a condition that affects polio survivors many years after recovery from an initial attack of the poliomyelitis virus. PPS is characterized by a further weakening of muscles that were previously affected by the polio infection. The most common symptoms include slowly progressive muscle weakness, fatigue (both general and muscular), and a decrease in muscle size (muscular atrophy). Pain from joint deterioration and increasing skeletal deformities such as scoliosis are common. Some individuals experience only minor symptoms, while others develop more visible muscle weakness and atrophy. PPS is rarely life-threatening but the symptoms can interfere significantly with the individual's capacity to function independently. While polio is contagious, PPS is not transmissible. Only a polio survivor can develop PPS. </s></s>

<s>[INST] What are the treatments for Post-Polio Syndrome ? [/INST] Presently, no prevention has been found that can stop deterioration or reverse the deficits caused by the syndrome A number of controlled studies have demonstrated that nonfatiguing exercises may improve muscle strength and reduce tiredness. Doctors recommend that polio survivors follow standard healthy lifestyle practices: consuming a well-balanced diet, exercising judiciously (preferably under the supervision of an experienced health professional), and visiting a doctor regularly. There has been much debate about whether to encourage or discourage exercise for polio survivors or individuals who already have PPS. A commonsense approach, in which people use individual tolerance as their limit, is currently recommended. Preliminary studies indicate that intravenous immunoglobulin therapy may reduce pain, increase quality of life, and improve strength modestly. </s></s>

<s>[INST] What is the outlook for Post-Polio Syndrome ? [/INST] PPS is a very slowly progressing condition marked by long periods of stability. The severity of PPS depends on the degree of the residual weakness and disability an individual has after the original polio attack. People who had only minimal symptoms from the original attack and subsequently develop PPS will most likely experience only mild PPS symptoms. People originally hit hard by the polio virus, who were left with severe residual weakness, may develop a more severe case of PPS with a greater loss of muscle function, difficulty in swallowing, and more periods of fatigue. </s></s>

<s>[INST] What is (are) Peripheral Neuropathy ? [/INST] Peripheral neuropathy describes damage to the peripheral nervous system, which transmits information from the brain and spinal cord to every other part of the body. More than 100 types of peripheral neuropathy have been identified, each with its own characteristic set of symptoms, pattern of development, and prognosis. Impaired function and symptoms depend on the type of nerves -- motor, sensory, or autonomic -- that are damaged. Some people may experience temporary numbness, tingling, and pricking sensations, sensitivity to touch, or muscle weakness. Others may suffer more extreme symptoms, including burning pain (especially at night), muscle wasting, paralysis, or organ or gland dysfunction. Peripheral neuropathy may be either inherited or acquired. Causes of acquired peripheral neuropathy include physical injury (trauma) to a nerve, tumors, toxins, autoimmune responses, nutritional deficiencies, alcoholism, medical procedures, and vascular and metabolic disorders. Acquired peripheral neuropathies are caused by systemic disease, trauma from external agents, or infections or autoimmune disorders affecting nerve tissue. Inherited forms of peripheral neuropathy are caused by inborn mistakes in the genetic code or by new genetic mutations. </s></s>

<s>[INST] What are the treatments for Peripheral Neuropathy ? [/INST] No medical treatments exist that can cure inherited peripheral neuropathy. However, there are therapies for many other forms. In general, adopting healthy habits -- such as maintaining optimal weight, avoiding exposure to toxins, following a physician-supervised exercise program, eating a balanced diet, correcting vitamin deficiencies, and limiting or avoiding alcohol consumption -- can reduce the physical and emotional effects of peripheral neuropathy. Systemic diseases frequently require more complex treatments. </s></s>
