Description
David López-Martos and a large cohort team characterize a subtle form of memory decline in a 2026 study of aging and early Alzheimer disease. Participants were cognitively unimpaired adults in a Spanish cohort who had spinal fluid tests and repeated memory testing over three years. The researchers defined decline with strict statistical thresholds across several memory tasks, rather than a single low score.
About one in ten of three hundred fifty participants met the definition. That group showed more Alzheimer pathology across blood and spinal fluid markers, brain scans for amyloid and tau, and grey matter volume. The profile helps researchers recognize a very early stage where prevention trials might intervene before clear symptoms appear.
