Simple focal seizures affect a small area of the brain. Simple focal seizures may cause twitching or a change in taste or smell. Focal seizures may occur due to trauma, stroke, or meningitis, which can scar the brain. A simple focal seizure can cause minor symptoms, which people call an “aura.” They may experience: 1. a feeling that something is ab...
A simple focal seizure may spread into other areas of the brain, becoming a complex partial seizure. As abnormal electrical activity affects a larger section of the brain, symptoms can become more severe. People may also refer to a complex partial seizure as a complex focal seizure or a focal unaware seizure. These seizures affect a person’s awaren...

Epilepsy. Overview. Epilepsy — also known as a seizure disorder — is a brain condition that causes recurring seizures. There are many types of epilepsy. In some people, the cause can be identified. In others, the cause is not known. Epilepsy is common.
A seizure is an electrical disturbance in the brain that interferes with its normal function. Many scientists and clinicians compare it to an “electrical storm in the brain” in which your brain cells hyper-synchronize in an abnormal pattern, disrupting that delicate brain signal balance.
