Motor and non-motor symptoms in Turkish patients with Parkinson's disease affecting family caregiver burden and quality of life.

Author information

Parkinson's disease (PD) decreases the quality of life (QoL) of both caregivers and patients by increasing stress and burden, and it has a negative impact on their psychological state. In the present study, the authors examined the impact of PD-patient motor and non-motor clinical symptoms on the psychological health, burden, and QoL of Turkish caregivers. The study included 50 patients with PD and their caregivers. Patients' disease severity and disability, motor and non-motor symptoms, disease complications, sleep disturbances, anxiety, and depressive symptoms were assessed with various scales. Data were analyzed by multiple linear-regression models to identify variables associated with caregiver burden, psychological status, and QoL. Anxiety and depressive symptoms exhibited by the patients significantly affected the psychological state of the caregivers. Caregiver burden was increased by disease severity; the patient's degree of disability, anxiety, and depressive symptoms; and excessive daytime sleepiness. Caregiver QoL was significantly affected by the presence of dyskinesia, sialorrhea, and anxiety symptoms in patients with PD. These findings indicate that caregiving for patients with PD, particularly those in later stages, with psychiatric symptoms, affects caregiver psychological status, QoL, and caregiver burden. These results can be used to develop treatment approaches to improve caregivers' psychological status and QoL and decrease caregiver burden.
