AbstractApathy is a common non-motor symptom of Parkinson disease (PD) that can affect the health-related quality of life (HRQoL) of patients and caregivers. This study aimed to investigate the clinical determinants of apathy and its impact on HRQoL in patients with early PD. We enrolled 324 patients with early PD with modified Hoehn-Yahr stages 1 to 3 and a disease duration ≤5 years. Demographic information was obtained, and motor and non-motor symptoms were evaluated with relevant scales. Apathy was present in 110 of 324 (33.9%) patients. Compared with patients with non-apathetic PD, those with apathetic PD had significantly higher modified Hoehn-Yahr stage, Unified Parkinson's Disease Rating Scale-II (UPDRS-II) score, Non-Motor Symptoms Scale (NMSS) total score, Beck Depression Inventory (BDI) score, and Parkinson's Disease Questionnaire-8 (PDQ-8) score. Clinical variables independently associated with the Apathy Evaluation Scale (AES) score were NMSS domain 3 score and BDI score. The univariate regression analysis revealed that the PDQ-8 score was significantly associated with age; disease duration; formal education duration; and UPDRS-III, UPDRS-II, NMSS total, Mini-Mental Status Examination, BDI, Beck Anxiety Inventory, and AES scores. Independent predictors of the PDQ-8 score in the multivariate regression analysis were UPDRS-III, UPDRS-II, NMSS total, NMSS domain 3, Beck Anxiety Inventory, and AES scores. In the present study, apathy was an independent predictor of HRQoL in patients with early PD. Therefore, identifying and managing apathy could help improve HRQoL in patients with early PD.Copyright © 2023 the Author(s). Published by Wolters Kluwer Health, Inc.
