BACKGROUND AND PURPOSE Disturbance of the autonomic nervous system (ANS) is frequently encountered in Parkinson's disease (PD). In this study, we examined changes in systemic and cerebral hemodynamics during the cold pressor test (CPT) to determine whether cerebrovascular reactivity, controlled by the sympathetic nervous system, is intact or impaired in patients with PD. METHODS Forty-nine patients with PD and 49 sex- and age-matched non-PD subjects were evaluated. Measurements were performed… CONTINUE READING
