Electrodiagnostics is the study and recording of electrical activity in the brain and nervous system.
Lancaster General’s skilled team of experts offers the following diagnostic tests:
Brainstem, visual auditory and somatosensory studies record electrical activity from the brain and spinal nerves in response to sight, sound or touch.
What to expect: Electrodes are placed on the scalp and other areas of the body as visual, auditory and electrical stimuli are introduced and recorded.
A painless procedure that detects abnormalities in the brain waves or electrical activity of the brain.
What to expect: Electrodes are placed on the scalp with a glue-like substance. The test takes about one hour while the patient remains still and relaxed. The patient may be asked to take repeated deep breaths and may be shown a flashing strobe light. Some patients may be asked by their physician to stay awake overnight for a sleep test.
Ambulatory EEG
This test records brain activity for 24 hours on a small recorder worn around the waist.
What to expect: Electrodes are placed on the scalp with a glue-like substance and the patient is sent home with a diary to record activities and any symptoms that may occur.
