Caregiver Burden and Quality of Life in Early and Late Stages of Idiopathic Parkinson's Disease

Objective: Idiopathic Parkinson's disease (IPD) is a chronic progressive neurodegenerative movement disorder characterized by motor and non-motor symptoms that affects patients' quality of life and caregiver burden. The aim of our study was to assess the caregiver burden (CB) in early and late stages of disease and to search if there was a relationship between quality of life and CB.; Methods: A total of 74 patients who were diagnosed as having IPD by a movement disorder neurologist according to United Kingdom Brain Bank Criteria and their caregivers were randomly selected for participation the study. Staging of PD was performed by the neurologist based on the Hoehn and Yahr (H&Y) Scale. Disease severity was determined using the Unified Parkinson's Disease Rating Scale (UPDRS). CB was evaluated using the Zarit Caregiver Burden Inventory (ZCBI). The Hospital Anxiety and Depression Scale (HADS) and the Beck Depression Inventory (BDI) were used to assess anxiety and depressive symptoms in patients with IPD and their caregivers. The Short-Form Health Survey instrument (SF-36) was used to evaluate quality of life of the patients. The Mini-Mental State Examination (MMSE) was administered to patients to evaluate gross cognitive status.; Results: Seventy-four patients (male, 58.1%) were included in the study. The mean age of patients was 66.18±8.5 and the mean duration of disease was 67.23±41.8 months. According to the H&Y scale, the patients were divided into two groups; stage I-II as early stage and stage III-V as late stage. Group 1 (H&Y I-II) consisted of 40 patients, and group 2 (H&Y III-V) comprised 34 patients. The mean duration of disease and UPDRS scores were significantly higher in group 2 (p=0.003, p=0.001, respectively). Significant differences were found in group 2 according to BDI. There were significant differences between group 1 and 2 according to SF-36 subdomains such as general health, emotional role, social functioning, pain, and mental health (p=0.019, p=0.038, p=0.005, p=0.004, p=0.014, respectively). However, there were no significant differences between these two groups concerning CB.; Conclusion: Although CB was found in 35 (47.3%) caregivers in our study, we found no significant differences between the caregivers of patients with early and late-stage IPD patients. We thought that this might be due to strong family relationships and cultural dynamics in Turkey. Burden was found to be higher in depressive patients' CGs and CGs who had depressive symptoms. It is important to recognize depressive symptoms earlier to protect the relationship between the CG and the patient because the main providers of care are family members.
