Apathy progression is associated with brain atrophy and white matter damage in Parkinson's disease.

ABSTRACT: Apathy is a prevalent non-motor symptom that significantly impacts the quality of life in Parkinson's disease (PD) patients. Although previous studies have investigated the neural correlates of apathy in PD, the longitudinal relationships between regional brain atrophy, white matter hyperintensities (WMHs), and apathy progression remain underexplored. Using longitudinal, multisite data of de novo PD patients from the Parkinson's Progression Markers Initiative (PPMI), the present study aims to investigate these relationships. We used T1-weighted magnetic resonance imaging (MRI) and clinical data from 445 participants. Apathy was assessed as part of the Movement Disorder Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part I. We applied deformation-based morphometry (DBM)
