Sound sleep therapy may sharpen memory in early Alzheimer's

This study tests whether playing gentle sounds during deep sleep can improve memory and reduce Alzheimer's-related proteins in people with mild cognitive impairment (MCI). About 114 participants, including those with MCI and healthy older adults, will have their sleep monitored and receive sound stimulation over several nights. Researchers will measure changes in sleep patterns, memory test scores, and blood markers of Alzheimer's disease.
