Summary

This study tests a portable device that plays soft sounds during deep sleep to improve memory and slow cognitive decline in older adults. Sixty participants aged 60-85 with mild memory problems will use the device at home for two 4-week periods. The goal is to see if enhancing slow-wave sleep can protect the brain and reduce dementia risk.

What this could lead to

If it works, this could lead to an affordable, home-use treatment that helps maintain brain health and slows memory loss in older adults.
