A case of post-anoxic encephalopathy with initial massive myoclonic status followed by alternating Jacksonian seizures.
To contrast stimulus-sensitive generalized myoclonus with ensuing multifocal localized myoclonus in a patient with post-anoxic coma, we stressed the clinical as well as electroencephalographical differences between his initial generalized and subsequent focal myoclonus. While generalized myoclonus was presumably of extracortical origin and responsive to valproic acid, alternating Jacksonian seizures were definitely cortical and suppressed with phenytoin. These two different types of myoclonus should not be confused in post-anoxic coma.
