Paroxysmal kinesigenic dyskinesia in a mother and daughter.
We report a rare case of familial paroxysmal kinesigenic dyskinesia. A 42-year-old woman and her 13-year-old daughter both presented with episodic curling of their hand and arm. These events were triggered by sudden movements and would last several seconds. Both patients' symptoms were unilateral and their physical and neurological examinations were normal. Treatment with carbamazepine improved their symptoms. Although an uncommon movement disorder it is important to recognize the clinical presentation of paroxysmal kinesigenic dyskinesia as most patients respond very well to medical treatment.
