The authors present a brief review of modern literature on paroxysmal dyskinesia. Two cases of kinesigenic praoxysmal dyskinesia (KPD) are described. In the first case (a 22-year-old man) attacks first developed at the age of 14 years. The disease was sporadic in nature and was attended by tapeto-retinal abiotrophy. Attacks were fully eliminated by the treatment with diphenin (phenytoin) or finlepsin (carbamazepin). The second patient, a 14-year-old boy, presented moderate intellectual disorders, parkinsonism and KPD attacks in the absence of a tetanic symptom complex. Some of the KPD attacks in this case, as in the first patient, developed during running, with some of the paroxysms being attended by backward running. Paraclinical examinations made it possible to diagnose pseudohypoparathyroidism. Therapy with dihydrotachysterol and calcium preparations brought about a dramatic clinical improvement, in particular a complete cessation of KPD attacks.
