title: Ten year follow-up of paroxysmal choreoathetosis: a sporadic case becomes familial.
abstract: A 30-year-old woman is reported who was originally described in 1967 as an isolated instance of paroxysmal choreoathetosis. In the subsequent 10 years, her movement disorder has decreased in severity. However, she now has a 7-year-old daughter with a similar but more persistent and more serious condition. This family emphasizes both variability of manifestations of paroxysmal choreoathetosis and the importance of genetic factors.
