Abstract

Purpose: We intended to elucidate the whole clinical course of Dravet syndrome (DS) comprehensively, from infancy through adulthood. Methods: Subjects were 31 patients with DS (14 with typical DS, and 17 with borderline DS) who were followed from childhood to at least 18 years of age. Their seizures, abilities, and electroencephalography (EEG) findings were investigated and statistically analyzed. Results: The clinical findings of the patients with typical DS and those with borderline DS became largely similar in adolescence and adulthood. Seizures were intractable in childhood in all patients, but suppressed in five (16.1%) during follow-up. Thirty-five (87.5%) of the 40 apparently generalized convulsive seizures that were captured by ictal EEG recording at 7 years of age or later were of focal origin. The seizure-free outcomes were significantly correlated with the experience of
