Ninety patients with PD and 20 age- and sex-matched healthy controls (HCs) were recruited. They used TCD (EMS-9D PRO) to simultaneously record non-invasive continuous BP (NIBP) and cerebral blood flow velocity (CBFV) at supine and orthostatic positions during the active standing test (AST).

The transcranial Doppler is an excellent way to study acute changes in CBFv in the autonomic clinic. Cerebral autoreg- ulationisawell-definedphysiologicalmechanismessentialin everydaylife.StandardizationofTCDrecordingsisessential.
