Improving Sleep via Phase-Locked Auditory Stimulation in Patients with Amnestic Mild Cognitive Impairment

Our project aims to test whether PLAS can improve sleep, memory and other aspects of cognition in older adults with and without amnestic mild cognitive impairment. We will apply novel, deep-learning-based techniques to optimally detect the smaller-size slow waves that are characteristic of older adults.

Participants’ brainwaves will be recorded while they are sleeping, and a quiet tone will be presented in real time to coincide with the next slow wave, thereby increasing its size. After each experimental night, we will measure cognition, memory consolidation, and blood flow to the brain.

We hypothesize that these outcome measures will be improved after a night of PLAS, relative to control. We will examine PLAS in both the lab as well as the home environment, which could then lead to widespread use of this method in both healthy and at-risk older adults.
