Summary
Four unrelated children (ages 8, 9, 16 and 17 years) with idiopathic paroxysmal kinesigenic dyskinesia responding to low dose oxcarbazepine are reported from the Department of Pediatric Neurology, Helen DeVos Children’s Hospital, Grand Rapids, MI. Case 1, dyskinesias developed at 5 years of age and were induced by sudden purposeful movements such as standing up, running or jumping. Attacks consisted of abrupt cessation of activity, staring straight ahead with a fearful facial expression, followed by ballistic flailing movements of the arms and athetoid movements of the body. Attacks lasted from 30 seconds to 2 minutes, and occurred up to 10 times a day.
