Slow-wave sleep is associated with nucleus accumbens volume in elderly adults
Slow-wave sleep (SWS) is essential for restorative neural processes, and its decline is associated with both healthy and pathological ageing. Building on previous rodent research, this longitudinal study identified a significant association between nucleus accumbens (NAcc) volume and SWS duration in cognitively unimpaired older adults. Our findings support the involvement of the NAcc in ageing-related modulation of SWS and suggest potential therapeutic targets for improving SWS.
