Epilepsy Types Directory
Epilepsy types vary by symptoms and treatments. Some types of epilepsy include childhood absence epilepsy, juvenile myoclonic epilepsy, temporal lobe epilepsy, and more. Diagnosing the particular type a person has can be done with MRI, EEG, and other tests. Follow the links below to find WebMD's comprehensive coverage about how different types of epilepsy are diagnosed and treated.
The Basics of Epilepsy
Read basic information about epilepsy and various types of seizures.
WebMD explains the causes, symptoms, and treatment of refractory epilepsy, which develops when your seizures aren't brought under control by medicine.
Lennox-Gastaut Syndrome-Topic Overview
Lennox-Gastaut syndrome is a severe form of childhood epilepsy that causes frequent seizures. Several types of seizures are usually present at the same time, including atonic or tonic seizures. These seizures can cause injury.Lennox-Gastaut syndrome may be caused by a variety of brain injuries. Other problems, such as intellectual disability, delays in physical and intellectual growth, and other mental and physical disabilities, may also be present. The condition can be difficult to treat. Treatment with medicines, the ketogenic diet, or a type of brain surgery called corpus callosotomy may help control some of the seizures that occur with this syndrome. Most children will continue to have seizures throughout life.
Diagnosing Epilepsy: EEG's Limits-Topic Overview
Electroencephalography (EEG) is thought to be the most useful test in confirming a diagnosis of epilepsy, but it is not foolproof. Some people with abnormal EEG results do not have epilepsy. This is not common.About 50% of people with epilepsy will have normal results on their first EEG.1 If epilepsy is still suspected, a follow-up EEG may be done. This second test may be a sleep-deprived EEG, in which the test is done after you have been forced to stay awake for a longer period of time than usual. A sleep-deprived EEG can sometimes reveal abnormalities that did not show up on the regular EEG.From 10% to 40% of people with epilepsy will have normal EEG results even after having several EEG tests done.1Video and EEG monitoring records seizures on videotape and computer so that the doctor can see what happens just before, during, and right after a seizure occurs. The video records what you are doing while the EEG records the electrical activity occurring in your brain. This type of
