What is (are) Atrial Fibrillation and Stroke ? 

Atrial fibrillation (AF) describes the rapid, irregular beating of the left atrium (upper chamber) of the heart. These rapid contractions of the heart are weaker than normal contractions, resulting in slow flow of blood in the atrium. The blood pools and becomes sluggish and can result in the formation of blood clots. If a clot leaves the heart and travels to the brain, it can cause a stroke by blocking the flow of blood through cerebral arteries. Some people with AF have no symptoms, but others may experience a fluttering feeling in the area of the chest above the heart, chest pain, lightheadness or fainting, shortness of breath, and fatigue. AF is diagnosed by an electrocardiogram (ECG), a device that records the hearts electrical activity. Other tests are often performed to rule out contributing causes, such as high blood pressure, an overactive thyroid gland, heart failure, faulty heart valves, lung disease, and stimulant or alcohol abuse. Some people will have no identifiable cause for their AF.
What are the treatments for Atrial Fibrillation and Stroke ? 

Within a few hours after onset of a stroke, treatment with drugs or devices that dissolve or break up the clot can restore blood flow to the brain and lead to a better recovery. To prevent strokes related to AF, doctors often prescribe medications to prevent formation of clots in the heart, which can travel to the brain and cause stroke. Immediately after a stroke, doctors may temporarily administer heparin by injection, while starting an oral medication for long-term protection from clots. The most commonly used drug has been warfarin. People taking warfarin must be closely monitored to make sure their blood is thin enough to prevent clots, but not so thin as to promote bleeding. Since some foods, vitamin supplements, and medications can affect warfarin action, keeping the blood just thin enough can be tricky. More recently, a number of new blood thinners, including dabigatran, rivaroxaban, and apixaban, have been shown to be as effective as warfarin in stroke prevention. These newer medications do not require regular blood test monitoring and may have less tendency to cause bleeding due to making the blood too thin. Some individuals with AF may have a lower risk of stroke and may be treated with aspirin, either alone or with another antiplatelet agency like clopidogrel. Other treatments for AF include medications such as beta blockers or calcium channel blockers to slow the heartbeat, and anti-arrhythmic drugs or electrical cardioversion (which delivers an electrical shock to the heart) to normalize the heartbeat.
What is the outlook for Atrial Fibrillation and Stroke ? 

AF, which affects as many as 2.2 million Americans, increases an individuals risk of stroke by 4 to 6 times on average. The risk increases with age. In people over 80 years old, AF is the direct cause of 1 in 4 strokes. Treating individuals with warfarin or new blood thinners reduces the rate of stroke for those who have AF by approximately one-half to two- thirds. People with AF can have multiple strokes, including silent strokes (strokes that don't show physical symptoms but show up on a brain scan) that, over time, can cause dementia, so prevention is important.
what research (or clinical trials) is being done for Atrial Fibrillation and Stroke ? 

The National Institute of Neurological Disorders and Stroke (NINDS) is the leading Federal agency directing and funding research relevant to AF and stroke prevention. The NINDS conducts basic and clinical research in its laboratories and clinics at the National Institutes of Health (NIH), and also supports additional research through grants to major research institutions across the country. Much of this research focuses on finding better ways to prevent, treat, and ultimately cure disorders such as AF that can increase the risk of stroke.
What is (are) Migraine ? 

The pain of a migraine headache is often described as an intense pulsing or throbbing pain in one area of the head. However, it is much more; the International Headache Society diagnoses a migraine by its pain and number of attacks (at least 5, lasting 4-72 hours if untreated), and additional symptoms including nausea and/or vomiting, or sensitivity to both light and sound. Migraine is three times more common in women than in men and affects more than 10 percent of people worldwide. Roughly one-third of affected individuals can predict the onset of a migraine because it is preceded by an "aura," visual disturbances that appear as flashing lights, zig-zag lines or a temporary loss of vision. People with migraine tend to have recurring attacks triggered by a number of different factors, including stress, anxiety, hormonal changes, bright or flashing lights, lack of food or sleep, and dietary substances. Migraine in some women may relate to changes in hormones and hormonal levels during their menstrual cycle. For many years, scientists believed that migraines were linked to the dilation and constriction of blood vessels in the head. Investigators now believe that migraine has a genetic cause.
What are the treatments for Migraine ? 

There is no absolute cure for migraine since its pathophysiology has yet to be fully understood. There are two ways to approach the treatment of migraine headache with drugs: prevent the attacks, or relieve the symptoms during the attacks. Prevention involves the use of medications and behavioral changes. Drugs originally developed for epilepsy, depression, or high blood pressure to prevent future attacks have been shown to be extremely effective in treating migraine. Botulinum toxin A has been shown to be effective in prevention of chronic migraine. Behaviorally, stress management strategies, such as exercise, relaxation techniques, biofeedback mechanisms, and other therapies designed to limit daily discomfort, may reduce the number and severity of migraine attacks. Making a log of personal triggers of migraine can also provide useful information for trigger-avoiding lifestyle changes, including dietary considerations, eating regularly scheduled meals with adequate hydration, stopping certain medications, and establishing a consistent sleep schedule. Hormone therapy may help some women whose migraines seem to be linked to their menstrual cycle. A weight loss program is recommended for obese individuals with migraine.
                
Relief of symptoms, or acute treatments, during attacks consists of sumatriptan, ergotamine drugs, and analgesics such as ibuprofen and aspirin. The sooner these treatments are administered, the more effective they are.
What is the outlook for Migraine ? 

Responsive prevention and treatment of migraine is incredibly important. Evidence shows an increased sensitivity after each successive attack, eventually leading to chronic daily migraine in some individuals With proper combination of drugs for prevention and treatment of migraine attacks most individuals can overcome much of the discomfort from this debilitating disorder. Women whose migraine attacks occur in association with their menstrual cycle are likely to have fewer attacks and milder symptoms after menopause.
what research (or clinical trials) is being done for Migraine ? 

Researchers believe that migraine is the result of fundamental neurological abnormalities caused by genetic mutations at work in the brain. New models are aiding scientists in studying the basic science involved in the biological cascade, genetic components and mechanisms of migraine. Understanding the causes of migraine as well as the events that effect them will give researchers the opportunity to develop and test drugs that could be more targeted to preventing or interrupting attacks entirely. Therapies currently being tested for their effectiveness in treating migraine include magnesium, coenzyme Q10, vitamin B12, riboflavin, fever-few, and butterbur. 
                
In 2010, a team of researchers found a common mutation in the gene TRESK which contains instructions for a certain potassium ion channel. Potassium channels are important for keeping a nerve cell at rest and mutations in them can lead to overactive cells that respond to much lower levels of pain. Large genetic analyses similar to the one used to identify TRESK will most likely lead to the identification of a number of other genes linked to migraine.
What is (are) Aicardi Syndrome ? 

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.)
What are the treatments for Aicardi Syndrome ? 

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.
What is the outlook for Aicardi Syndrome ? 

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.
what research (or clinical trials) is being done for Aicardi Syndrome ? 

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.
What is (are) Refsum Disease ? 

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.
What are the treatments for Refsum Disease ? 

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.
What is the outlook for Refsum Disease ? 

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.
what research (or clinical trials) is being done for Refsum Disease ? 

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.
What is (are) Frontotemporal Dementia ? 

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.
What are the treatments for Frontotemporal Dementia ? 

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.
What is the outlook for Frontotemporal Dementia ? 

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.
what research (or clinical trials) is being done for Frontotemporal Dementia ? 

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.
What is (are) Shaken Baby Syndrome ? 

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.
What are the treatments for Shaken Baby Syndrome ? 

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.
What is the outlook for Shaken Baby Syndrome ? 

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.
what research (or clinical trials) is being done for Shaken Baby Syndrome ? 

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.
What is (are) Gerstmann-Straussler-Scheinker Disease ? 

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.
What are the treatments for Gerstmann-Straussler-Scheinker Disease ? 

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.
What is the outlook for Gerstmann-Straussler-Scheinker Disease ? 

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.
what research (or clinical trials) is being done for Gerstmann-Straussler-Scheinker Disease ? 

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.
What is (are) Syringomyelia ? 

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.
What are the treatments for Syringomyelia ? 

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.
What is the outlook for Syringomyelia ? 

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.
