What happens after the test?

The electrodes are removed and the glue that held them in place is washed away with acetone. You may have to use additional acetone at home to completely remove the glue. Unless you are actively having seizures or are restricted by your physician, you may drive home. If the EEG was performed overnight, you should arrange to have someone drive you home.

A neurologist/epileptologist examines the EEG recording for abnormalities in the brain-wave pattern, which might reflect diseases of the nervous system, including epilepsy.
