CRANIAL TRAUMA AND EXTRAPYRAMIDAL INVOLVEMENT

Abstract
The possible relationship between parkinsonism and cerebral trauma is still controversial. Many cases have been reported in which parkinsonism seems to follow trauma, but other authors have expressed the opinion that traumatic parkinsonism has never been established by postmortem findings. The authors report 3 cases of head injury in which the predominant involvement occurred in the extrapyramidal nuclei of the brain. The localization of the lesions indicated that a syndrome resembling parkinsonism could be expected to develop on the basis of trauma. The patho-anatornic changes resemble those observed under conditions of exptl. and other forms of cerebral anoxia.
