Strength Training May Reshape Brain Markers in Older Adults With Early Alzheimer's Signs
A 24-week strength training program altered Alzheimer's-related brain signatures in cognitively healthy older adults. The effect was strongest in participants who already had amyloid buildup in their brains. Those reductions in brain thickness markers were linked to better executive function, suggesting the changes were adaptive rather than harmful. This was a small trial of 90 people around age 72, so the results need replication.
Two Opposing Brain Fuel Patterns May Predict Who Keeps Their Cognition With Age
Brain white matter (the wiring that connects brain regions) uses glucose differently depending on where you look. In over 3,000 participants across two studies, higher glucose use in expected areas like the corpus callosum linked to better thinking skills. But higher glucose use in unusual areas like the corona radiata linked to worse cognition, likely a sign the brain is compensating. Over time, people with strong "normal" metabolism and low "compensatory" metabolism declined more slowly.
Sticking With Mediterranean or MIND Diets Linked to Lower Dementia Risk
Following a Mediterranean or MIND diet long-term was linked to meaningful reductions in dementia risk in a study of over 130,000 U.S. nurses and health professionals. Those with the highest Mediterranean diet scores had 21% lower dementia risk, while top MIND diet followers had 14% lower risk. Higher adherence was also tied to 0.75 to 1.59 fewer years of cognitive aging and roughly 40% lower risk of self-reported cognitive decline. Even people who improved their diet over 4 or 8 years saw similar benefits.
