Electroencephalography (EEG)
New Britain General campus: (860) 224-5538
Brain cells communicate by producing tiny electrical impulses. An electroencephalogram (EEG) is a painless test to detect abnormalities in the brain's electrical activity. Electrodes are placed on different areas of the patient's scalp to detect and record patterns of electrical activity and check for abnormalities.
EEG can help determine the causes of confusion; diagnose seizure disorders; and evaluate other conditions, including tumors, infections, sleep disorders and head injuries.
An EEG technician will attach the electrodes and conduct the test. Patients lie or sit quietly while a machine records electrical activity in wavy lines on a piece of paper. Patients may be asked to do certain things during the recording, such as breathe deeply and rapidly for several minutes or look at flashing lights.
