It is the result of sudden usually brief excessive electrical discharges in a group of brain cells. Any part of the brain can be the site of epilepsy.

Seizures are classified according to the site of the brain in which they arise as follows generalized seizures, partial or focal seizures and which then trigger and are followed by generalized attack.

Any kind of brain disease (infection, injury, vascular, tumour, congenital and degenerative) can cause seizures.

In many cases, where there is no detectable brain disorder, the most commonly accepted theory is that seizures are a result of an imbalance of the chemical neurotransmitter in the brain.

There are some provocative factors in some patients for epilepsy like photic stimulation (disco lights, television, computers, etc.) overbreathing, overhyrdation, loss of sleep,emotional and physical stress.
