Why is an EEG performed?
An electroencephalogram (EEG) is a neurological test that measures the electrical signals your brain. The types of problems for which an EEG might be requested include seizure disorders, head injuries, learning problems, headaches, brain tumors, dizziness, amnesia, staring episodes, and sleep disturbances. An EEG does not measure intelligence, thoughts, or feelings. The EEG machine does not send electricity into the brain; it only measures the electricity that your brain produces.
