Startle disease or hyperekplexia: adolescent onset and response to valproate.
We report a boy with rigidity and hyperekplexia or startle disease which began in adolescence. His symptoms completely resolved with valproic acid therapy. Two relatives have the minor form of this disorder, suggesting autosomal dominant inheritance with variable penetrance.
