EEG Appearances in Acute Carbamazepine Toxicity
Abstract
A 16-year-old woman deliberately took a large, toxic overdose of carbamazepine and recovered despite a high plasma level. During the acute phase the EEG was dominated by occipital delta activity suggestive of a brainstem disorder. Following 24-h treatment with activated charcoal the plasma carbamazepine was cleared and the EEG returned to normal.
