Identifying sleep disorders, seizure disorders, epilepsy and to assess brain activity following a severe head injury or stroke.
EEG is a recording of the on-going electrical activity of the brain and is used to detect abnormalities in brain wave patterns. It can be used in the comfort of your home at night to detect sleep disturbance or even used during the day (ambulatory EEG) where users can move around with monitors.
Electrodes are placed on the cranial area and other parts of the head and neck to monitor and measure electrical waves.
There is little preparation required by the patient for EEG except to ensure that the head and hair are clean of ointments or lotions so that they will not obstruct the electrode recording activity. Stimulants such as coffee should also be avoided. Your doctor may ask you to avoid medication for a period of time.
