EEG- Brain Wave Activity

For this question we have not yet organized an advisory council in the specified regions and/or condition

Question

My nine-year-old son had an EEG and an MRI done. The EEG revealed that his "brain waves are decreased." Nothing else was noted. Can you explain what this means?

Answer of our experts

Decreased amplitude of brain waves on the EEG may be a drug effect, eg, Tegretol. It is a benign finding, not at all uncommon in people with developmental problems. It does not imply seizures.
