An EEG, or electroencephalogram, is a test that can help diagnose epilepsy. During an EEG, the electrical signals of the brain are recorded. This electrical activity is detected by electrodes, or sensors, placed on the patient's scalp and transmitted to a polygraph that records the activity.
EEG-video monitoring - Video cameras are used to record seizures as they occur, while EEG electrodes on the scalp monitor the brain's activity. The characteristics of the persons behavior during a seizure can help to identify the seizure focus. This is generally done over several days in a special monitoring room.
Dr. Chez examines the EEG recording for abnormalities in the brain-wave pattern, which may reflect diseases of the nervous system.
Through this process, Dr. Chez advised the family to consider Invasive monitoring - Also called intracranial EEG, this technique involves surgically placing electrodes inside the skull directly in or over a specific area of the brain to record electrical activity. Invasive monitoring also may be used to stimulate areas of the brain to help determine which areas are associated with critical functions such as memory, movement and language.
