Tests that have been done on people with epilepsy commonly show uneven activity or large changes in the voltage of brain waves (spikes). Sometimes, the brain of the person with epilepsy functions perfectly normal during the test. An EEG can only measure abnormal electrical activity that occurs during the test period.
It is important to remember that an abnormal EEG does not diagnose epilepsy nor does a normal EEG reading exclude epilepsy. This safe and painless procedure will not affect your child in any way. A neurologist uses these recordings to help identify the location, severity and type of seizure disorder. An electroencephalograph is the instrument used to register this activity and record it on graph paper.

The EEG allows the doctor see if there are any irregularities electrical activities occurring in the brain that may produce seizures.Īn electroencephalogram is a non-invasive diagnostic test.
