Seizures

Seizures are the result of abnormal patterns of electrical activity in the brain. There are many different types of seizures because the irregular activity can affect any part of the brain.

Seizures associated with a change in electrical activity are called epileptic seizures. Seizures not associated with a change in electrical activity are called nonepileptic seizures. However, the most common types of seizures are as follows:

• Grand mal seizures affect the entire brain. Entire body spasms and complete loss of consciousness are hallmarks of grand mal seizures.
• Petit mal seizures may only involve brief episodes of staring and unresponsiveness.
• Partial seizures only affect a small part of the brain and may have very specific symptoms.

Seizures can be isolated events. Recurrent seizures can be a sign of epilepsy. Seizures may occur with symptoms, including:

• Difficulty with memory
• Hallucinations
• Loss of vision or changes in vision
• Changes in hearing, taste, or smell
• Changes in mood, personality, or behavior
• Confusion or loss of consciousness for even a brief moment

Following a seizure, the person may feel weak or tired or have changes in mood and behavior.
