Description
Kim and co-authors ask in 2025 whether brain size shifts during a single day, and whether sleep the night before plays a part. They studied 1,003 healthy Korean adults aged 60 and older with no mental health illness. Each person rated their sleep and had a brain scan, and the team noted the time between waking and the scan.
Brain size showed no clear link to time of day on its own. Yet for people who slept well, some brain measures were lower in the mid group than in the early or late groups. The work warns scan studies to note sleep and timing, since both can sway the numbers they report.
