Statistical comparison for gender was done through the chi-square test while the others were compared using the Kruskal Wallis rank-sum test. EDS–, patients without EDS; EDS+, patients with EDS; MoCA, montreal cognitive assessment; GDS, 15-item geriatric depression scale; HADS, hospital anxiety and depression scale; UPDRS-III, movement disorder society (MDS)– Unified Parkinson's Disease Rating Scale– Part III; ESS, epworth sleepiness scale; TIV, total intracranial volume. The bold values are significant values.
