Electroencephalogram (EEG)

Electroencephalogram (EEG)

What is an EEG?

An Electroencephalogram (EEG) is a medical test performed at Doylestown Hospital that measures and records brain wave patterns to identify problems with the brain's electrical activity.

A safe and fast way to record brain activity, the EEG results help physicians understand how the brain is working electrically and look for abnormalities. The test is usually ordered by a neurologist or a sleep medicine physician.

What Happens During an EEG

The non-invasive, outpatient procedure does not hurt and you should be comfortable. The test takes about 30 minutes to complete.

The technologist will ask you to lie down or sit in a chair, then attach electrodes to various places on your scalp. The electrodes connect to a piece of equipment called the EEG amplifier, which tracks and records the brain's electrical signals, then sends them to a computer where they can be analyzed.

Your doctor should give you any instructions about what is needed to prepare for your EEG.

Generally, no special preparation is needed; however, there are specialized EEG studies which may be done under different conditions. Ask your physician if any special instructions are needed to prepare for your test.

Why is an EEG Done?

An EEG can help your doctor diagnose and monitor seizures, observe sleep patterns and check brain function after a head trauma.

EEG is useful in diagnosing and monitoring epilepsy and other conditions that affect brainwaves.

Your doctor will talk with you about the results and answer any questions you may have.
