DASH Diet Edges Out Other Diets for Slower Cognitive Decline

A large study of over 159,000 participants found the DASH diet had the strongest and most consistent association with lower cognitive decline risk and better cognitive function with age compared with five other dietary patterns. Vegetables and fish were linked to better outcomes, while red/processed meats, fried potatoes, and sugary beverages were linked to worse outcomes, with the wine result needing cautious interpretation. The findings are observational and do not prove causation, but support the idea that diet quality—especially vascular/metabolic health—may influence brain aging.

Sugary Substitutes May Speed Up Midlife Memory Decline, Study Finds

An eight-year study of 12,772 adults (mean age ~52) found that higher consumption of several low- and no-calorie sweeteners (except tagatose) is linked to faster cognitive decline, especially among those under 60 and people with diabetes. The results show correlation, not causation, and health authorities say approved sweeteners remain safe while further research is needed.

Brain Changes Tie Hearing Loss to Dementia Risk, Study Finds

Brain Changes Tie Hearing Loss to Dementia Risk, Study Finds

A new study links age-related hearing loss (presbycusis) to cognitive decline through coupled functional and structural brain changes. Researchers introduce the Functional-Structural Ratio (FSR), derived from MRI measures, which correlates with worse hearing and poorer cognitive performance in specific brain regions, suggesting FSR could serve as a biomarker for dementia risk. While cross-sectional, the findings highlight the potential of preserving hearing health to protect brain integrity and guide early interventions.

Long-Term Coffee and Tea Intake Linked to Lower Dementia Risk, Large Harvard Study Finds

Long-Term Coffee and Tea Intake Linked to Lower Dementia Risk, Large Harvard Study Finds

A Harvard-led study of 131,821 participants followed for up to 43 years found that drinking two to three cups of caffeinated coffee daily or one to two cups of tea daily was associated with an ~18% lower risk of dementia, lower prevalence of subjective cognitive decline, and better performance on cognitive tests, with decaffeinated coffee showing no benefits. Results held across genetic risk groups, suggesting caffeine may be the active protective factor, though the effect size is small and caffeine should be one part of a broader cognitive-health strategy.

Where Fat Hangs Out Predicts Brain Aging Risk

Where Fat Hangs Out Predicts Brain Aging Risk

A 25,997-person UK MRI study used latent profile analysis to classify body-fat distribution into six patterns. Compared with the leanest group, all non-lean profiles showed lower brain volumes and less gray matter, independent of total fat. Two patterns—pancreatic-predominant and skinny-fat—were most strongly linked to brain aging, white-matter lesions, and cognitive decline, with some sex-specific effects (men showing faster brain aging and women showing links to epilepsy for the pancreatic-predominant type). While higher BMI correlated with brain changes, fat location adds independent risk. The study is cross-sectional and can’t prove causation, but if validated these fat-distribution patterns could inform earlier interventions for neurodegenerative risk.

Grandparent caregiving tied to better cognitive health

Grandparent caregiving tied to better cognitive health

Using data from 2,887 older adults (mean age 67) in the English Longitudinal Study of Ageing, researchers report that grandparents who provided grandchild care scored higher on memory and verbal fluency and showed less cognitive decline over 2016–2022, regardless of care frequency or type. The findings suggest caregiving may benefit grandparents’ brain health, though effects may depend on a voluntary, supportive family context and require replication.

Leading Doctor Warns Against Brain-Damaging Foods

Consuming liquid sugar, especially through sugary drinks like soda and sweetened beverages, can cause long-term brain damage by inducing inflammation, insulin resistance, and cognitive decline, with particularly harmful effects on children and young adults. Artificial sweeteners may also accelerate mental decline, and reducing sugar intake by choosing healthier alternatives can help protect brain health.

Leading Doctor Warns of Brain-Damaging Food to Avoid

Consuming liquid sugar, especially in sugary drinks like soda and sweetened beverages, can cause long-term brain damage by leading to insulin resistance, inflammation, and oxidative stress, which impair memory, focus, and increase dementia risk. Early exposure in children is linked to attention problems and ADHD, and artificial sweeteners may also accelerate cognitive decline. Reducing intake and replacing sugary drinks with water or unsweetened beverages can help protect brain health.

Potential Brain and Heart Risks Linked to Artificial Sweeteners in Diet Products

A Brazilian cohort study suggests that high consumption of non-caloric artificial sweeteners may be associated with accelerated cognitive decline over eight years, raising concerns about their long-term safety despite regulatory approval, with potential mechanisms involving neurotoxicity and gut microbiota alterations.
