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.
A body of studies is showing that a blood marker called p-tau217 can forecast an elevated risk of cognitive impairment in healthy older adults years before symptoms appear. The evidence is not yet clinical-ready, but it is guiding trials that aim to slow or prevent Alzheimer’s disease and is being tested in Scotland’s primary care setting.
International researchers find inherited genetics influence how cancers evolve after DNA damage, affecting tumour growth and mutation patterns. The Edinburgh-led work, published in Nature, underlines implications for screening, diagnosis and personalised treatment across populations.
A UK study across 18 cities shows a rise in e-scooter-related injuries among under-16s and adults, with limb, head and facial injuries most common. Helmet use remains very low. Researchers urge clearer public health messaging and tighter private-e-scooter regulations as trials continue.
