Electroencephalogram (EEG) is the study and recording of electrical activity in the brain and nervous system.
EEG is used to evaluate several types of brain disorders such as seizures, epilepsy, Alzheimer's disease, and narcolepsy. When epilepsy is present, seizure activity will appear as rapid spiking waves on the EEG.
This painless, non-invasive procedure detects abnormalities in the brain waves or electrical activity of the brain. We place electrodes on your scalp and you are asked to remain still and relaxed for about one hour. You may be asked to take repeated deep breaths and may be shown a flashing strobe light. The electrodes are attached to a computer that measures changes in electrical activity in your brain.
This test records brain activity for 24 hours on a small recorder worn around your waist. We place electrodes on your scalp and your return home with a diary to record activities and any symptoms you may experience.
