Mass General Brigham researchers have discovered that specific brain wave patterns during sleep can predict cognitive impairment years before symptoms emerge. Using an AI tool to analyze EEG data from women over 65 tracked for five years, they achieved a 77% accuracy rate in identifying those who would develop impairment. The study focused on gamma band frequencies during deep sleep and suggests wearable devices could facilitate early detection and intervention. Further research is needed to validate these findings across broader populations.
Study Overview
