- QUESTION: After experiencing several episodes of seizures, my cherished
- cousin is to have a test called an "encephalogram". She calls me every day to
- discuss this, but I know nothing about the test, and wish I could offer some
- more support. Could you explain a bit about this test to me? Is there any
- danger to it and what are they looking for? I appreciate your column very
- much and hope you will be able to help me now.

- ANSWER: Recurrent seizure episodes raise the possibility that your cousin may
- have epilepsy. Not all convulsions are seizures and not all seizures may be
- caused by epilepsy, so testing is now in order to try and discover the true
- cause of the problem. The "electroencephalograph" (or EEG) is a graph that
- displays the electrical action of the brain cells. The graph displays these
- as brain waves, and special brain wave patterns are typical of epilepsy and
- allow a rather precise diagnosis.
- To prepare for the test, a number of electrodes are taped to the head, to
- detect the electrical activity. Usually a test will take from 30 minutes to 1
- hour, but depending upon the findings, it may be continued for a longer time.
- Patients may be exposed to flashing lights or other sounds and images to
- provoke a seizure, and often a video camera is used to film the patient's
- activity. An EEG is a painless and safe procedure.
