Neurological test battery
B‐SIT, Impaired orthostatic tolerance, orthostatic intolerance, Hg decrease, orthostatic blood pressure
Participants underwent a broad neurological test battery including objective tests of cognitive, motor, autonomic, and sensory (color vision and smell) function. Cognitive assessments included the psychometric battery from the UDS3 standard and LBD modulesMotor function was assessed via the Timed Up and Go (TUG),Autonomic function was measured with orthostatic blood pressure, in which blood pressure was measured after lying supine for 5 min, then 3 min after standing. Impaired orthostatic tolerance was defined as ≥20 mm Hg decrease in systolic blood pressure and/or a ≥ 10 mm Hg decrease in diastolic blood pressure. Severe orthostatic intolerance was defined as ≥30 mm Hg decrease in systolic blood pressure and/or a ≥ 15 mm Hg decrease in diastolic blood pressure.The Brief Smell Identification Test (B‐SIT; Version A, Sensonics Inc.
