Description
Laura Korthauer, Julia Sinople, Zachary Gemelli, William Heindel, and Elena Festa published a 2025 brain study on a resting EEG measure and mental resilience in healthy older adults. In Alzheimer disease, resting brain waves slow down, a pattern captured by the ratio of theta to beta power. Whether that ratio shows anything before symptoms, in people at varied risk, was the question.
The study compared 25 older adults at high genetic and family risk with 25 at low risk, all cognitively unimpaired. Each gave five minutes of resting brain wave data from 64 channels and filled questionnaires on perceived decline and cognitive reserve, the buffer built by life experience. Frontal theta beta ratios were computed for left, middle, and right sites.
