Epilepsy is a condition that causes seizures — temporary glitches in the brain’s electrical activity. These electrical disruptions can cause a range of symptoms. Some people stare off into space, some make jerky movements, while others lose consciousness.
Doctors don’t know what causes epilepsy. Genes, brain conditions like tumors or strokes, and head injuries may be involved in some cases. Because epilepsy is a brain disorder, it can affect many different systems throughout the body.Epilepsy may stem from changes in the brain’s development, wiring, or chemicals. Doctors don’t know exactly what causes it, but it can start after an illness or damage to the brain. The disease disrupts the activity of brain cells called neurons, which normally transmit messages in the form of electrical impulses. An interruption in these impulses leads to seizures.There are many different kinds of epilepsy, and different types of seizures. Some seizures are harmless and barely noticeable. Others can be life-threatening. Because epilepsy disrupts brain activity, its effects can trickle down to affect just about every part of the body.
