The well-being and burden of caregiving for patients with Parkinson's disease.

Parkinson's disease caregivers reported more impairment in psychological well-being and higher rates of distress. In the total sample of caregivers (of patients with PD and of healthy individuals), depression and specific areas of well-being (environmental mastery, personal growth) correlated to the burden of caregiving. Psychosocial interventions focused on these dimensions may help caregivers to better cope with the possible burden of the assistance.
