Abstract
Paroxysmal movement disorders are a group of heterogeneous entities that have been categorized based on their most salient features. The four classic categories of paroxysmal dyskinesias are kinesigenic, nonkinesigenic, hypnogenic, and exercise‐induced. The phenotypic variability of these disorders, coupled with new insights into their possible etiologies, has made the task of classification increasingly problematic. We describe 4 cases that do not fit easily into the current classification scheme, compare them with four others recently described in the literature, and raise the question as to whether they constitute a new subtype. © 2005 Movement Disorder Society

The last event demonstrates running as a precipitant to a paroxysmal attack strong enough to induce a fall. Segment 2. Three events of Case 2 are documented.

The last clip is at age 11 and is taken after a long car ride with difficulty getting out of the car because of dyskinesia. Segment 3. Case 3 at age 9 demonstrating a typical, choreic attack occurring during the day both while standing and seated. Segment 4. Case 4 at 14 months capturing an event in sleep followed by a waking event occurring on his mother's lap. He is unable to stand with support during the episode.
