Multivariate linear regression model determined that age (unstandardized β, −0.0025 [SE 0.0001]; p = 0.02), N2 sleep duration (unstandardized β, 0.0002 [SE 0.0001]; p = 0.04), and the apnea-hypopnea index (unstandardized β, −0.0011 [SE 0.0005]; p = 0.03) were independently associated with DTI-ALPS. Higher DTI-ALPS was associated with better ECog language scores (unstandardized β, −0.59 [SE 0.28]; p = 0.04) and better CERAD-NB word list learning delayed recall subtest scores (unstandardized β, 6.17 [SE 2.31]; p = 0.009) after covarying for age and education. Higher DTI-ALPS was also associated with higher gray matter volume (unstandardized β, 107.00 [SE 43.65]; p = 0.02) after controlling for age, sex, and total intracranial volume.Discussion Significant associations were identified between glymphatic function and sleep, stressing the importance of sleep for brain health. This study also revealed associations between DTI-ALPS, neuropsychological performance, and cerebral gray matter volumes, suggesting the potential of DTI-ALPS as a biomarker for cognitive disorders.AD=Alzheimer disease; AHI=apnea-hypopnea index; AQP4=aquaporin 4; CERAD-NB=Consortium to Establish a Registry for Alzheimer's Disease Neuropsychological Battery; DTI=diffusion tensor imaging; DTI-ALPS=diffusion tensor imaging–analysis along the perivascular space; ECog=Everyday Cognition; FA=fractional anisotropy; FDR=false discovery rate; MMSE=Mini-Mental State Examination; NREM=non-REM; PSG=polysomnography; PSQI=Pittsburgh Sleep Quality Index; PVS=perivascular spaces; ROI=region of interest
