摘要
The frequency of orthostatic hypotension (OH) in cohorts of patients recruited through hospital Parkinsons disease (PD) clinics ranges from 16%to 58%. How ever, hospital based cohorts may be subject to ascertainment bias. The aim of th is study was to determine the frequency of OH in a community based population of PD patients and to determine the demographic features of patients with and with out OH. Forty two (47%) of patients met the criteria for OH. Subjects with OH w ere older than those without OH, but there was no difference in PD disease durat ion or severity, MMSE or depression rating between the groups.
