EEG or Electroencephalography is a test used to study brain wave patterns. It can provide your doctor with information about the nature of the type of difficulties you’ve been experiencing.
A specially trained EEG technician will first measure your head with a tape measure. He will then rub certain spots on your scalp lightly and place about 20 gold disc electrodes with a light cream on those spots. You will be asked to recline in a chair or lay in a bed for about half an hour while a special machine records your brain waves. During the sessions you may be asked to breathe in and out deeply and lights may be flashed before while your eyes are closed.
The EEG does not involve needles or electrical stimulation of any kind. It is a completely painless procedure.
If you have any questions regarding the EEG procedure or wish to cancel/reschedule, please call 212.606.1047.
