Description
Peter Fried and co-authors test a brain wave ratio as an early flag for Alzheimer's disease. Their 2025 study deals with cerebral slowing, a drift of EEG power from fast to slow bands as the disease brews. A ratio of fast over slow band power captures the drift. Past work found the ratio low in dementia and in amyloid-backed mild decline, and tied it to weaker executive scores.
Here the test turns to symptom-free elders, with a blood amyloid ratio as the stand-in for brain amyloid. Resting EEG, thinking tests, and blood draws came from dozens of older adults. The hunt: does the ratio flag silent disease?
