Researchers at the University of Nottingham Medical School have found a mechanism by which healthy physical activity might protect against alzheimer’s disease (Corticotropin-Releasing Factor Receptor 1 Activation During Exposure to Novelty Stress Protects Against Alzheimer’s Disease-Like Cognitive Decline in AβPP/PS1 Mice). It has been known from past research that physical and mental activity may reduce the likelihood of developing Alzheimer’s Disease. However, why these are beneficial is still being investigated. In their recently published paper, authors Scullion, Hewitt & Pardon note an apparent paradox (emphasis mine):

Susceptibility to stress is a risk factor for AD but positive lifestyle factors effective in delaying AD progression in mouse models (e.g., exercise, environmental enrichment) improve stress resistance despite inducing a number of markers of chronic stress
