What is Epilepsy ?
Epilepsy is a condition in which a person suffers from repeated seizures (fits).

What is the cause of a seizure ?
The brain is the control center for the body like a computer of the highest generation. It is made up of millions of tiny nerve cells or neurons.Each neuron has an electric voltage difference across its membrane. A seizure occurs when there is a sudden surge or excess or chaos in the normal electrical activity in groups of neurons (called the seizure focus).This abnormal electric discharge spreads to the rest of the brain & soon there is total disruption of the normal function of the brain.
This abnormal activity could be restricted to a small part of the brain leading to focal seizure (seizure involving only a small part of the body) or could be generalised i.e. the entire body is involved.

How does a seizure manifest ?
Many patients do have a peculiar strange feeling before the occurance of a seizure. The seizure could consist of fall with generalised convulsive movement of all the limbs. These movements could also be restricted to a few muscles only.
Some patients might just keep staring or show some characteristic movements like lip smacking etc.
some might just be unresponsive for a few minutes.
