Burden, Anxiety, and Depression Among Caregivers of Parkinson's Disease Patients.

Background: Parkinson's disease (PD) is a disabling neurodegenerative movement disorder. Most PD patients are looked after by caregivers who are close to them regardless of their relationship. Caregivers may experience a notable impact on their mental health as they dedicate a significant amount of time to the patient while observing the progression of the disease.

Objective: The aim of this study was to evaluate the level of burden, depression, anxiety, and stress among caregivers of PD patients.

Methods: We conducted a cross-sectional analysis between July and September 2023 among caregivers of PD patients following in the Movement Disorders Clinic at King Khalid University Hospital in Riyadh, Saudi Arabia, and through the Saudi Parkinson's Society. The data collection was done anonymously through an electronic self-administered questionnaire. Caregiver burden was assessed by using the validated Arabic version of the Zarit Burden Interview (ZBI) scale, and the Depression Anxiety Stress Scale (DASS) was used to assess the presence and level of anxiety and depression.

Results: There were 118 caregivers (53.39% female, 33.9% aged between 35- 45 years, and 73.73% were sons/daughters) caring for 118 patients (57.63%, male, 38.98% aged between 66- 76). The ZBI score was highest among sibling caregivers. Moreover, burden scores were higher among those who provided care more frequently than others.

Conclusions: Our study revealed that PD caregivers face a high risk of care burden, especially those who are siblings and spend longer periods in patient care. Additionally, female caregivers reported higher rates of depression, anxiety, and stress.
