Large UK Study Suggests HRT May Lower Dementia Risk in Women

A UK Biobank study of about 183,000 postmenopausal women followed for around 13 years found that those who used hormone replacement therapy (HRT) for at least one year had roughly 10% lower overall dementia risk and 16% lower Alzheimer’s risk compared with non-users, with the largest reduction (26%) among women who had undergone surgical menopause. However, the findings are observational and can’t establish causality; factors like education and other health variables may influence results. More research, including randomized trials, is needed, and women should consult their GP when considering starting or stopping HRT.

High-Dose DHA Fails to Boost Cognition or Prevent Dementia in At-Risk Adults

High-Dose DHA Fails to Boost Cognition or Prevent Dementia in At-Risk Adults

A randomized, double-blind trial found that two years of high-dose DHA supplementation raised brain and blood DHA levels in older adults at risk for dementia, but it did not improve cognitive function or brain structure compared with placebo, even among APOE ε4 carriers. The study suggests DHA alone does not prevent dementia, though omega-3s remain beneficial as part of a balanced diet and brain-healthy lifestyle.

Omega-3 pills don’t boost memory in new brain-health study

A randomized, double-blind trial found that high-dose omega-3 algae supplements did not improve memory or cognition in adults at risk for dementia, even though blood and cerebrospinal fluid showed higher omega-3 levels. The researchers say benefits come from overall healthy lifestyle choices—exercise, sleep, and a Mediterranean-style diet with fatty fish—rather than supplements alone.

USC Targets Hidden Alzheimer's Inflammation Trigger with Brain-Penetrant Inhibitor

USC researchers identified selective inhibitors of the brain inflammation enzyme cPLA2 that may lower Alzheimer’s risk, especially for APOE4 carriers; the compounds cross the blood-brain barrier, showed activity in brain cells and mouse models, and represent a promising but early-stage drug discovery path with safety and feasibility in humans to be determined.

Diverse midlife activities beat genetic risk in protecting brain health

Diverse midlife activities beat genetic risk in protecting brain health

A Trinity College Dublin study of 700 adults aged 40–59 finds that a varied mix of social, physical, and intellectual activities in midlife boosts cognitive health to a greater extent than carrying the APOE ε4 gene, with variety across activities offering the strongest protection; depressive symptoms and traumatic brain injury are the most harmful risk factors, highlighting a cost-effective window for dementia prevention in midlife.

Meat and APOE4: Possible Dementia Risk Reduction Found in Carriers

Meat and APOE4: Possible Dementia Risk Reduction Found in Carriers

An observational study following 2,157 people over up to 15 years found that eating more meat was linked to a lower dementia risk only among APOE4 carriers; for non-carriers, meat intake showed no overall cognitive benefit. However, a higher ratio of unprocessed to total meat was associated with lower dementia risk in all participants, and higher processed meat intake tended to raise risk. The study does not prove causation and clinicians caution that more research, including trials, is needed before genotype-tailored dietary recommendations can be made.

Higher unprocessed meat intake linked to slower dementia progression in APOE4 carriers

A Swedish observational study found that adults over 60 with APOE3/4 or APOE4/4 genotypes who consumed more unprocessed meat had slower cognitive decline and a lower risk of dementia, compared with those eating less meat; processed meat was associated with higher risk. The study does not prove causation and intervention studies are needed.

Biomarker may flag dementia risk for certain menopause hormone therapies

Biomarker may flag dementia risk for certain menopause hormone therapies

New analysis of WHI data finds that higher baseline plasma p-tau217, an Alzheimer's biomarker, is linked to a substantially higher dementia risk, especially for women on combined estrogen–progesterone therapy started later in life; estrogen-only therapy did not show the same pattern. The risk was strongest among women over 70, white women, and APOE4 carriers, suggesting hormone interactions with brain vulnerability rather than a direct cause. Starting combined hormone therapy around menopause for five years or less generally does not raise dementia risk, but starting after 65 may for some women. Biomarkers like p-tau217 could help identify who is most at risk.

Eye-dwelling bacteria linked to Alzheimer's risk could aid early detection

A Nature Communications study found higher levels of the bacterium Chlamydia pneumoniae in retinal tissue of people with Alzheimer's disease, with greater bacterial burden associated with more severe cognitive decline. The findings, supported by lab and mouse models, suggest retinal infection and inflammation may reflect brain pathology and that APOE4 carriers had higher retinal bacterial levels, pointing to retinal imaging as a potential noninvasive biomarker and possible infection-targeted therapies.

Should You Discover Your Genetic Risk for Alzheimer's?

The article discusses the implications of discovering your genetic risk for Alzheimer's disease, particularly the APOE4 gene, highlighting that while genetic testing can inform about increased risk, lifestyle choices such as sleep, exercise, diet, and inflammation management play a crucial role in mitigating this risk. It emphasizes that genes are not destiny and encourages proactive health habits regardless of genetic results.

Leqembi Endorsed for Early Alzheimer's Therapy

Leqembi Endorsed for Early Alzheimer's Therapy

The European Medicines Agency's human medicines committee has recommended Leqembi (lecanemab) for treating early Alzheimer's disease in patients with one or no copies of the ApoE4 gene, due to a lower risk of amyloid-related imaging abnormalities (ARIA). This decision follows a re-examination of data showing Leqembi's benefits in slowing cognitive decline outweigh its risks in this restricted population. The recommendation includes safety measures like MRI monitoring and a controlled access programme to mitigate ARIA risks. The decision now awaits approval from the European Commission.
