Abstract
Motor dysfunction is frequently noted in human immunodeficiency virus type 1 (HIV-1)-infected patients. Until recently, neuropathological changes found in the basal ganglia were advanced as pathogenetic mechanisms. In the present study, further brain structures involved in motor control were analyzed morphometrically. The volume density, numerical density, and the size of neurons in the cerebellar dentate nucleus and in both inferior olivary nuclei were determined. In both regions of HIV-1-infected brains, a significant reduction in the volume density, the numerical density of neurons and neuronal size was apparent. The morphometric data from the present study disclose involvement of both types of nuclei investigated during the course of HIV-1 infection, and might constitute a possible morphological substrate for the motor dysfunction seen in HIV-1-infected patients.
