Clearing beta-amyloid plaques does not repair key brain functions, according to new research on the drug lecanemab. The researchers are, unfortunately, just catching up to what we’ve all known. http://sciencealert.com/one-of-our-biggest-hopes-for-alzheimers-treatment-doesnt-seem-to-work

A research team “rebalanced the activity” of a specific set of overactive neurons in the amygdala of mice and found that they reversed the symptoms of anxiety. https://www.sciencedaily.com/releases/2025/11/251104013004.htm

Walnuts, which are high in omega-3 fatty acids, polyphenols, flavonoids, and antioxidants, supported focus and memory and improved cognitive function in a new study. For max benefit, consume raw to protect the omega-3 fatty acids. https://foodandwine.com/walnuts-breakfast-brain-health-study-11840393

Frequent consumption of ultra-processed foods was associated with altered brain structure, and those differences could be part of a feedback loop promoting overeating, according to a study of 30,000 participants. https://sciencedaily.com/releases/2025/10/251020092824.htm

A new device is helping those with advanced age-related macular degeneration see again, and likely provides cognitive protection by supporting brain stimulation. https://www.nbcnews.com/health/health-news/tiny-eye-implant-special-glasses-legally-blind-patients-can-read-rcna238488

Flavanols, found in green tea, berries, broccoli, and other foods, have long been found to reduce cardiovascular disease risk. Now, a study shows flavanol-rich supplements reduced age-related inflammation, likely promoting cognitive health as well. https://doi.org/10.1093/ageing/afaf269

99% of heart attacks and strokes were preceded by at least one of just four risk factors. Unsurprisingly, they are all also connected with cognitive decline. https://www.sciencealert.com/huge-study-links-99-of-heart-attacks-and-strokes-with-four-risk-factors

Tiny protein clusters, called alpha-synuclein oligomers, anti-microbial proteins that may be very early triggers of Parkinson’s disease, have been directly visualized for the first time. https://www.sciencefocus.com/news/hidden-trigger-parkinsons

Three researchers won the Nobel Prize for their work on regulatory T cells (Tregs), unraveling how the immune system knows to attack foreign entities and not our own cells. https://www.cnn.com/2025/10/06/science/nobel-prize-medicine-brunkow-ramsdell-sakaguchi-immune-system-intl

Those who ate the most riboflavin (vitamin B2) cut their dementia risk in half compared to those who ate the least in a new longitudinal study. Folate (B9) and vitamin B6 also reduced risk. https://www.eatingwell.com/riboflavin-for-lower-dementia-risk-study-11824281

Increasing daytime sleepiness and worsening circadian rest-activity rhythms were associated with a higher risk of dementia. This tiredness could be a symptom of an energy imbalance, where your brain demands more than it is being supplied. https://www.neurology.org/doi/10.1212/WNL.0000000000213403

Women are more likely to develop Alzheimer’s-related dementia than men, but a new study has found that men have higher hospitalization and mortality rates than women following a dementia diagnosis, even after adjusting for age and comorbidities. https://www.medpagetoday.com/neurology/dementia/116964

A precise, personalized brain stimulation was found to ease depression rapidly, and even reduced anxiety. The connection between mental health and dementia means this research is worth following. https://newatlas.com/mental-health/hd-tdcs-brain-stimulation-precise-depression/

In a new preprint, Dr. Ram Rao found that the ReCODE protocol significantly reduced depression scores in patients with cognitive impairment.

A recent study has found that high sugar intake can increase your risk of dementia by as much as 43%. Researchers also found that genetics can influence these numbers even further. But we already knew that, didn’t we? https://www.eatingwell.com/sugar-dementia-risk-study-11787744

We’ve highlighted the link between pollution/toxins and Alzheimer’s for years. Please take precautions, avoid polluted air when possible, use HEPA filters (or similar) in your home, and detox when air quality is low. https://jamanetwork.com/journals/jamaneurology/article-abstract/2838665

An antiparasitic used to treat pinworm can help lower the tau levels in mice. The drug targets misshapen nuclear speckles and restores their shape, reducing tau levels without causing cellular stress. https://today.ucsd.edu/story/antiparasitic-drug-shows-power-against-alzheimers-and-dementia

Can exercise prevent or help treat cancer? According to new research, yes. The study found that a single exercise session of resistance or high-intensity interval training increased anti-cancer myokines and reduced the growth of cancer cells. Wow. https://pmc.ncbi.nlm.nih.gov/articles/PMC12259798/

According to Dariush Mozaffarian, the best vegetable (or really, fruit) for heart health is the avocado.

A new analysis of the efficacy of lecanemab and donanemab found a high likelihood that the antibodies had no effect for those with 2 copies of APOE4. Given the higher risk of side effects, they recommend these individuals should not receive the treatment. https://pubmed.ncbi.nlm.nih.gov/40225236/

Herpes simplex virus type 1 is becoming an established risk factor for dementia, and evidence is building that treatment with antivirals for various infections may reduce dementia risk. https://www.medscape.com/viewarticle/can-preventing-treating-herpes-reduce-dementia-risk-2025a1000kna

A heart drug slowed accumulation of phosphorylated tau protein-217 (p-Tau 217) in those with cardiovascular disease in a new trial. While the drug targets cholesterol, much of the benefit may simply come from improved cardiovascular health. https://www.medpagetoday.com/meetingcoverage/aaic/116765
