The perivascular space (PVS) has been reported to clear Amyloid-β (Aβ) and metabolic wastes during sleep. However, the relationship between sleep and PVS in a healthy cohort is still unclear. We investigate the association between PVS and sleep across different age groups. We found that the effect of sleep on PVS volume varies in the young and older population.
