Types of Epilepsy
| Epilepsy is
NOT contagious and people with epilepsy are NOT "crazy." The word
"epilepsy" is derived from a Greek word meaning "to possess, seize or
hold." Changes in the way the brain processes electrical signals can
cause result in abnormal functioning. In people who have epilepsy,
cerebral cortical neurons misfire and result in seizures. This is similar to an electrical brainstorm.
The seizure prevents the brain from:
Types of EpilepsyThere are many types of epilepsy. Each type of epilepsy has different behavioral effects and is treated with different methods. In some cases, people know they are about to have a seizure because they see or hear something, or feel dizzy, nauseous, or "strange." This is called an aura. An aura can act as an "early warning system" telling a person that a seizure is about to happen. The person can therefore minimize a possible injury by taking precautions such as sitting down.
Brain damage resulting from these events may cause a "scar" on the brain. This is where an epileptic seizure starts. At this time it is not known why a scar starts a seizure. There may be a genetic link for some types of epilepsy, but this is usually NOT the case. Sometimes a seizure will be started ("triggered") by:
Brain imaging methods (magnetic resonance imaging [MRI] or computer tomography [CT] scanning) may also be used to find the location of a scar or damaged brain tissue. Sometimes positron emission tomography [PET] is used to examine brain blood flow.
Treatment for Epilepsy
Experimental TreatmentsSeveral treatments for epilepsy are still under investigation. How and if they work is still controversial.
|Epilepsy is a fairly common neurological disorder. It occurs in about 1 in every 100-200 people. Throughout history there have been many famous people who have had epilepsy:|
