What Are Seizures?
Abnormal brain functions that can occur during seizures include:
- Complete or partial loss of consciousness
- Involuntary jerks, tremors, or other simple movements
- More complex, but involuntary movements, such as turning in circles
- Confusion or nonsensical speech
- Unusual sensations in the head or body
- Loss of ability to speak or understand speech
- Memory loss
Each type of epilepsy is a malfunction of a particular area of the brain, with the temporal lobe region being the most commonly affected area. However, the forms can be simplified into three basic categories based on the origin of the epileptic condition. These include:
- Idiopathic Epilepsy
- Epilepsy which is thought to have a genetic cause. There are no other symptoms or reasons for the condition to exist and the brain appears to be normal when a seizure is not occurring. This type of epilepsy usually responds well to medication therapies.
- Symptomatic Epilepsy
- Epilepsy that is the result of an abnormality or lesion of the brain, either present at birth or caused later in life by a traumatic incident such as a head injury, stroke, infection, tumor, or other injury.
- Cryptogenic Epilepsy
- This form of epilepsy appears to have no known cause and the onset of seizures may begin at any time in an individual's life.
