1 The typical EEG in SWS is asymmetric, with local voltage depression and background slowing ipsilateral to the affected hemisphere. This asymmetry may be seen from the first months of life, but becomes more evident as atrophy of the hemisphere progresses. Decreased diazepam-enhanced β activity in the EEG is a sensitive criterion of functional abnormality. In patients with subtle structural abnormalities diazepam-enhanced EEG may have added value in diagnosing functional involvement and in monitoring disease progression in patients.33,34 Source: Focal Nonepileptoform Activity, Atlas of Pediatric EEG Citation: Laoprasert P.
