Electroencephalography (EEG) | Epilepsy Foundation
网页EEG is an important test for diagnosing epilepsy because it records the electrical activity of the brain. It is safe and painless. Electrodes (small, metal, cup-shaped disks) are attached to your scalp and connected by wires to an electrical box.
EEG Procedure - Epilepsy Foundation
网页The test is performed by an EEG technologist. First the technologist will measure your head so she can put the electrodes in the right place. A wax crayon, which can be easily washed off later, is used to mark the points on your scalp where the electrodes should be placed.
Diagnosis Through an Ambulatory EEG | Epilepsy Foundation
网页An ambulatory EEG may be done if you continue to have seizures after trying various seizure medications. The testing can either confirm the diagnosis of epilepsy or find that epilepsy waves are not causing the seizures. Ambulatory EEG monitoring is generally done at a specialized epilepsy center.
Which EEG type is best? - Epilepsy Foundation
网页Which EEG type is best? Since epilepsy is a disorder affecting the electricity of the brain, the electroencephalogram (EEG) is critical in the evaluation of people with seizures. For many years, EEG meant “routine” EEG, a brief (20 to 30 minutes) recording without video.
How to Read an EEG | Epilepsy Foundation
网页This section gives a brief introduction to how EEG electrodes are set up, what they mean and what the doctors can learn from reading an EEG.
Video EEG Test | Diagnosing Seizures | Epilepsy Foundation
网页Identify the type of seizures (like absence seizures) and their frequency. Find the region of the brain where seizures begin. Locating the exact region is vital if epilepsy surgery is being considered. Other names for video EEGs include EEG telemetry, EEG monitoring, or video EEG monitoring.
What if the EEG is Normal? - Epilepsy Foundation
网页Approximately one-half of all EEGs done for patients with seizures are interpreted as normal. Even someone who has seizures every week can have a normal EEG test. This is because the EEG only shows brain activity during the time of the test.
Making Sense Out of an EEG - Epilepsy Foundation
网页What does it mean when an EEG shows spikes, sharp, or slow waves? First it’s important to realize that it may mean something very different for each person. Some waveforms or activity on an EEG are normal, while others may be within normal limits for some people but not others. Spikes or sharp waves are terms commonly seen in EEG reports.
Diagnosis - Epilepsy Foundation
网页Receive an Electroencephalogram (EEG) An EEG is a safe and painless test that looks for changes in your brain's electrical patterns that relate to seizures. Some abnormal patterns may occur with many different conditions, not just seizures. Learn about EEG testing.
Benign Rolandic Epilepsy | Epilepsy Foundation
网页EEG (electroencephalogram): Children with CECTs have spikes on their EEG in the centrotemporal regions of the brain. These findings help confirm the diagnosis. MRI (magnetic resonance imaging): This test is usually normal in children with CECTS. It is often not needed if the history and EEG are very typical. Example of an EEG in a child with …
