A University of Florida-led study reported an association between use of the joint-health supplement glucosamine and a higher risk of progressing from mild cognitive impairment to dementia, as well as higher mortality among patients already diagnosed with Alzheimer’s disease and related dementias. The researchers emphasized that the findings do not prove glucosamine causes cognitive decline and said the results should be tested in clinical trials.

A new study of more than 2,100 Australian adults has found that higher consumption of ultra-processed foods is associated with reduced attention and slower mental processing, even among those following otherwise healthy diets. The research also connected greater intake to increased dementia risk factors such as obesity and high blood pressure.
A new study has found that adults with higher vitamin D levels in their 30s and 40s tend to have lower levels of tau protein in their brains about 16 years later. Tau is a key biomarker associated with dementia. The research, published this week, highlights a potential modifiable risk factor for brain health.

A study of over 375,000 Finns has linked hospital treatment for severe infections like cystitis and pneumonia to a higher risk of developing dementia within five to six years. Researchers identified 29 conditions associated with at least a 20 percent increased risk, with infections playing a key role. The findings suggest that preventing such infections could help modify dementia risk.
Depression diagnosed for the first time in older adults was more common in the years leading up to a diagnosis of Parkinson’s disease or Lewy body dementia and remained elevated for years afterward, according to a large Danish registry study. The authors said the pattern—stronger than in several other chronic illnesses—supports the possibility that depression can be an early feature of these neurodegenerative conditions rather than only an emotional response to disability.

A 20-year randomized controlled trial has shown that cognitive speed training, combined with booster sessions, reduces the risk of dementia diagnosis by 25 percent among older adults. The study, involving over 2,800 participants aged 65 and older, focused on a computer-based task requiring quick recall of visual details. While results are promising, experts urge caution due to the study's multiple outcome measures.
