Epilepsy
The cause of most cases of epilepsy is unknown, although some people develop epilepsy as the result of brain injury, stroke, brain tumor, and substance use disorders. Genetic mutations are linked to a small proportion of the disease.[6] Epileptic seizures are the result of excessive and abnormal cortical nerve cell activity in the brain.The diagnosis typically involves ruling out other conditions that might cause similar symptoms such as fainting. Additionally, making the diagnosis involves determining if any other cause of seizures is present such as alcohol withdrawal or electrolyte problems.This may be done by imaging the brain and performing blood tests.[6] Epilepsy can often be confirmed with an electroencephalogram (EEG) but a normal test does not rule out the condition.
Seizures are controllable with medication in about 70% of cases. In those whose seizures do not respond to medication, then surgery, neurostimulation, or dietary changes may be considered. Not all cases of epilepsy are lifelong, and some people improve to the point that medication is no longer needed.
About 1% of people worldwide (65 million) have epilepsy, and nearly 80% of cases occur in developing countries.In 2013 it resulted in 116,000 deaths up from 111,000 deaths in 1990. Epilepsy becomes more common as people age.In the developed world, onset of new cases occurs most frequently in infants and the elderly;in the developing world this is in older children and young adults, due to differences in the frequency of the underlying causes. About 5–10% of all people will have an unprovoked seizure by the age of 80, and the chance of experiencing a second seizure is between 40 and 50%. In many areas of the world those with epilepsy either have restrictions placed on their ability to drive or are not permitted to drive,but most are able to return to driving after a period of time without seizures.- Links
