Framingham data suggest menopause timing is not what first raises women’s pulse pressure

Study (observational, Framingham Heart Study). Habib, Gary F. Mitchell and colleagues report in Hypertension (doi 10.1161/HYPERTENSIONAHA.126.27015) on 6,760 unique participants across three visits spanning 14 years. Pulse pressure reached a nadir and flipped from falling to rising about a decade earlier in women (late 30s; modeled nadirs ~37–39) than in men (late 40s; ~47). Early, typical, or late menopause had no influence on when women’s pulse pressure bottomed, and postmenopausal nadirs sat an average of 6, 14, and 19 years before the final menstrual period. After age 60, mean pulse pressure was higher in women than in men. Association is not a reason to start, stop, or change blood-pressure medicine. Educational vascular-aging notes, not a diagnosis.

Western-style diet linked to faster attention decline in older APOE ε4 carriers

Study (observational). Carolina Blagojevic Castro and colleagues at Murdoch University and Alzheimer’s Research Australia report in Nutrients (doi 10.3390/nu18162592) from the Western Australia Memory Study: 185 Perth older adults followed more than seven years, none with diagnosed dementia at entry. Greater adherence to a Western pattern (red and processed meat, chips, pizza, sweets, refined grains, beer) tracked faster decline in attention among APOE ε4 carriers. The association was not seen across the whole sample, not in non-carriers, and not for a Prudent pattern (fruit, vegetables, leafy greens, whole grains) versus cognitive decline. Observational only — not a prescription to genotype-diet or a dementia diagnosis. Educational nutrition notes.

Low dementia prevalence in Amazonian communities may reflect shorter survival, not lower incidence

Study (longitudinal). Margaret Gatz, Hillard Kaplan and colleagues report in Alzheimer’s & Dementia (doi 10.1002/alz.71750) on 730 Tsimané and Mosetén adults in the Bolivian Amazon without dementia at first assessment, revisited nearly five years later. They identified 22 new dementia cases (7.40 per 1,000 person-years); follow-up prevalence stayed below 2%. Incidence was not dramatically lower than U.S. and northern European figures, especially under age 80. People with dementia had more than six times the mortality of those with normal cognition, and survival after diagnosis appeared two to three times shorter than in U.S. studies. Cognitive pattern leaned toward attention and task-management more than memory; blood work associated cases with neurofilament light, not amyloid or phosphorylated tau typical of Alzheimer’s. Twenty-two cases are too few to settle lifestyle versus genetics. Educational brain-aging notes, not a diagnosis.
