Epilepsy is a neurological condition that causes unprovoked, recurrent seizures. A seizure is a sudden rush of abnormal electrical activity in your brain. Doctors diagnose epilepsy when you have two or more seizures with no other identifiable cause.
Seizures are the main symptom of epilepsy. Symptoms differ from person to person and according to the type of seizure.
Focal (partial) seizures
A focal aware seizure (previously called simple partial seizure) does not involve loss of consciousness. Symptoms include:
alterations to sense of taste, smell, sight, hearing, or touch
dizziness
tingling and twitching of limbs
