[The dynamic mental status of patients who have undergone stereotaxic destruction of the ventrolateral thalamic nuclei].

Examined were 80 patients with parkinsonism and 20 patients torsional dystonia before and after stereotaxic cryodestruction of the ventrolateral thalamic nuclei. A set of tests was used to evaluate attention, memory, associative processes, generalization, comprehension to examine these patients. Only in the group of parkinson patients a reduction of these findings was noted (memory, perception, comprehension). All other mental activity types suffered similarly in all patients after the operations.
