Since the brain uses electrochemical energy , any disruption of the electrical processes in the brain will cause abnormal functioning. Unfortunately, this is just what happens during epilepsy - neurons in the cerebral hemispheres misfire and create abnormal electrical activity. People with epilepsy have seizures that happen repeatedly. It is a bit like an electrical brainstorm. That is why people with epilepsy may fall down and twitch.
Epilepsy is a fairly common neurological disorder.
It occurs in about 1 in every 100-200 people. There are many types of epilepsy. Each type of epilepsy has different behavioral effects and is treated with different methods. This is called an aura . The person can therefore minimize a possible injury by taking precautions such as sitting down.
