Seizures can affect people of all ages and walks of life. They occur when there is a sudden, brief change in electrical activity in the brain. These episodes can be caused by epilepsy, stroke, or an imbalance of body fluids or chemicals. Common symptoms may include:
- Involuntary movement of arms and legs
- Periods of confused memory
- Fainting spells.
There are two general types of seizures: generalized (all brain cells are involved) and partial (brain cells not working properly are limited to one part of the brain).
People who have had two or more seizures are often diagnosed with epilepsy.
