CLINICOL-ELECTROPHYSIOLOGICAL FEATURES OF PARKINSON’S SYNDROME IN CASE OF BREIN TUMORS

Results of the complex clinical-electrophysiological research. Including EEG, trunkal acoustic (ATEP) and visual evoked potentials (VEP). Of 120 patients with tumors of the brain of various localization and histologic structure are presented. In all patients extrapyramidal symptoms were noted. The Parkinson’s syndrome has been revealed in 57 (47.5%) patients. Features of theclinic and pathogenesis of Parkinson;s syndrome in case of intrabrain tumors of basal ganglia and thalamus.
According to EEG-data and the evohed potentials of a different modality alectrophysiological criteria of injury of subcortical structures in case of tumors of the brain are produccd. It is emphasized, that in patogenesis of Parkinson’s syndrome in case of tumor of the brain the deformation and displacement of subcortical-trund structures has essential value, especially mesencephalic sections of the brain stem.
