Original abstract
This study evaluated the autonomic nervous function in 6 patients with progressive supranuclear palsy (PSP). The autonomic nervous functions in PSP patients were compared with those in 17 patients of Parkinson's disease (PD) and 9 age-matched healthy control subjects. Results were that all PSP patients and 59% of PD patients had sympathetic skin response (SSR) abnormalities. Significant abnormalities in cardiovascular response observed in PD patients suggested the presence of sympathetic and parasympathetic disturbances. There were no significant differences between PSP patients and control subjects in cardiovascular responses. But some of PSP patients showed abnormal cardiovascular responses compared with the results from the control subjects. In PSP patients mild disturbances in cardiovascular responses and sudomotor dysfunction were suggested. We consider that the high incidence of SSR abnormality is at least partially related to the presence of disturbances in the frontal lobes.
