EEG testing

An electroencephalogram, or EEG, is a test that measures and records the electrical activity of your brain. The test should not hurt, but you will be asked to remain very still for a time.

The test works by attaching electrodes to your scalp, or to a cap worn over your head. Again, this should not hurt, but might be unpleasant. The electrodes (small metal discs attached to wires) work by detecting small electrical charges given off by the activity of your brain. Those charges then appear on a graph which will be displayed on paper or on a computer screen. Your doctor will use that graph to see how your brain is behaving.

An EEG can take anywhere from 45 minutes to two hours to complete. EEGs are often used to diagnose patients with Alzheimer's, stroke or head trauma. Depending on what your doctor is looking for, part of the test might involve exposing you to certain stimuli, like bright lights or activity. If your doctor is trying to determine the cause of a sleep disorder, part of the test might take place when you are sleeping.

You will be greeted by the same friendly staff in our familiar building as when you are coming in for a regular doctors' appointment.
