Transplantation and surgical treatment of parkinsonian syndromes.
Neurosurgical attempts to correct parkinsonism use strategies aimed either at alleviating the underlying dopamine deficiency or at correcting abnormal compensatory effects in neural circuits within the basal ganglia. During the review period, clinical trials of four different neurosurgical approaches were reported. These approaches are intracerebral transplantation of fetal dopamine neurons, intracerebral transplantation of adrenal medullary tissue, tremor-reducing surgical lesions in the ventrolateral thalamus, and ventroposterior pallidotomy aimed at reducing akinesia and rigidity. Experimental studies in rats and monkeys designed to explore mechanisms of graft actions were also reported.
