Epilepsy is a neurological condition involving the brain that makes people more susceptible to having recurrent unprovoked seizures. It is one of the most common disorders of the nervous system and affects people of all ages, races and ethnic background. According to the CDC, almost 3 million Americans live with epilepsy and nearly 200,000 people in the U.S. develop this condition annually.
Anything that interrupts the normal connections between nerve cells in the brain can cause a seizure; this includes a high fever, low blood sugar, alcohol or drug withdrawal, or a brain concussion. Under these circumstances, anyone can have one or more seizures. However, when a person has two or more recurrent unprovoked seizures, he or she is considered to have epilepsy. There are many possible causes of epilepsy, including an imbalance of nerve-signaling chemicals called neurotransmitters, tumors, strokes, and brain damage from illness or injury, or some combination of these. In the majority of cases, there may be no detectable cause for epilepsy.
