Myoclonus after brain anoxia is more commonly observed in adults. Peri natal anoxia, however, on rare occasions causes myoclonus as the main neurologic abnormality, In this paper we described a case of cerebral palsy complicated by chorea and tremulous movements of the foot in whi ch there were no risk factors except perinatal asphyxia. The patient h ad unique symptoms, action myoclonus associated with the movements of hyperkinesie volitionnelle. This case illustrated two points, One is t hat abnormal involuntary movements attributed to perinatal brain insul ts had changed as the brain matured, The other is that some movements were very similar to those of the post-anoxic action myoclonus, common ly seen in patients who sustain brain damage in adulthood.
