Effects of Real vs. Soundless Acoustic Stimulation During Deep Sleep on Brain Activity, Memory, and Blood Biomarkers in Older Adults (60-85) With Mild Memory Impairment

Summary

This study aims to explore a non-invasive way to improve memory and slow cognitive decline in older adults by enhancing sleep quality. Dementia, a leading cause of death worldwide, is often associated with disturbed sleep, particularly the loss of deep, slow-wave sleep (SWS). SWS is important for memory and clearing waste from the brain. Poor SWS can worsen memory loss and allow harmful waste to build up, which may increase the risk of dementia. The investigators are testing whether phase-locke
