Abstract

Purpose

Depression is a common sign of suffering among the patients with Parkinson's disease (PD). Frequent and severe neuropsychiatric symptoms lead to high levels of distress in patients and their caregivers, which results in the high levels of caregiver burden. The aim of this study was to determine the predictors of caregiver burden in caregivers of the patients with Parkinson's disease (PD).

Methods

The study included 183 consecutive PD patients and their caregivers. Patients were assessed using the Hoehn and Yahr scale, Mini Mental State Examination (MMSE), Beck Depression Inventory (BDI), and Schwab and England Activities of Daily Living Scale. Caregivers’ depressive symptoms were evaluated using the Caregiver Burden Inventor (CBI), BDI, and World Health Organization Quality of Life Scale.

Results

All of the patients reported one or more neuropsychiatric symptoms. Patients’ and caregivers' depressive symptoms, caregivers' age and education, time for caregiving, and quality of life were significantly associated with the increased caregiver burden. After controlling the level of education as a potential confounding variable, depression in both patients and caregivers, time for caregiving, and quality of life explained 45.6% of the variance in caregiver burden.

Conclusion

Substantial attention needs to be given to the early identification of depression in PD patients and their caregivers to improve caregivers' quality of life and burden.
