Purpose: to examine the effects of psychological stress on biological mechanisms of autonomic dysfunction, specifically SSR parameters Sample: male and female subjects with PD and controls ()
Arithmetic calculations using the WAIS-R arithmetic subscale
Biological mechanisms: 4-channel Nihon Kohen Neuropack S/MFrB 5504K used to record SSR in accordance with International Federation of Clinical Neurophysiology Guidelines
Biological mechanisms: no significant differences in SSR parameters were demonstrated between subjects or controls before or after the induction of psychological stress.
Purpose: to examine the effects of psychological stress on symptom outcomes, specifically goal directed movements and hedonic responsiveness Sample: male and female subjects with PD and controls ()
Arithmetic calculations while listening to loud music (protocol not specified)
Symptom outcomes: Eshkol and Wachman coding system for reach-to-grasp movements, duration of forward and backward movements, and emotional state questionnaire (tool not specified)
Symptom outcomes: stress was associated with significant deteriorations in mood and reduced hedonistic responsiveness in subjects with PD. Stress did not result in significant differences in each-to-grasp movements between subjects and controls.
Purpose: to examine patterns of psychological problems in subjects with PD to include symptom frequencies and health outcomes Sample: male and female subjects with PD
Not applicable
Symptoms outcomes: Inventory of Psychosocial Stress in PD Health outcomes: Inventory of Psychosocial Stress in PD and benefits of social support questionnaire (tool not specified)
Symptom outcomes: Symptom increases with even small amounts of stress were reported by approximately two-thirds of subjects. Higher stress levels were associated with greater frequencies in depressive moods, sleep disturbances, anxiety, sexual problems, and communication difficulties. Health outcomes: higher stress was associated with greater difficulties coping with PD, worsening social relationships, less enjoyment of life, and the need for more psychological support.
