The brain: center of thought, sensation and control.
[Synopsis here]
A two-year Latin American trial has shown that older adults at risk of dementia who followed a structured lifestyle program—combining supervised exercise, brain-healthy diet guidance, cognitive training, and social activity—outperformed a control group in cognition, memory, and processing speed.
New studies show a blood biomarker, p-tau217, can indicate Alzheimer’s risk years before symptoms in healthy older adults. The finding could speed up drug trials by identifying high‑risk volunteers, though researchers caution it is not for routine screening yet. Separate efforts in Scotland testGP-based blood diagnostics to speed diagnosis and treatment decisions.
Independent reports that a theoretical model suggests median human lifespan could reach 146–194 years if all ageing factors are eliminated except somatic mutations, while Alzheimer’s breakthroughs explore seeds of amyloid beta and SORLA’s role in tau tangles.
