EEG Testing
EEG TESTING
Electroencephalogram (EEG) is a test used to record spontaneous electrical activity in your brain over a period of time. It is essentially a noninvasive, painless procedure in which flat metal discs known as electrodes are attached to the scalp to track electrical impulses, which are then translated as wavy lines on an EEG recording. EEG is used to diagnose epilepsy, brain death and other brain disorders; study sleep disorders such as narcolepsy; evaluate dementia or periods of unconsciousness; and predict chances of recovery after a change in consciousness. EEG tests are effective in distinguishing epileptic seizures from other seizures. It is also used to determine the best treatment option, based on seizure type. Sometimes, seizures are intentionally triggered while testing on people with epilepsy, so as to make accurate diagnosis.
A clinical EEG recording usually lasts 20-30 minutes, including preparation and recording time. EEG may be performed while you are awake or asleep. Patients typically lie on their backs on an examining table or bed with their eyes closed, while the EEG technologist makes direct observations during the test. Heritage Neurology offers outstanding EEG testing service, using the best technology available. Our well-trained neurophysiologist at interprets these signals to make the most accurate diagnosis and determine the best treatment for each case.
