Electrodiagnostics


Electrodiagnostics is the study and recording of electrical activity in the brain and nervous system.


Lancaster General Health's skilled team of experts offers the following diagnostic tests:
 

Electroencephalogram (EEG)

  • 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.

If you have questions regarding your test, or need to reschedule an appointment, please call 717-544-3170.
