Heat waves have intensified health risks, worsening heart and kidney conditions, triggering heat exhaustion, and contributing to inflammatory issues. Experts urge hydration, shade, and cooling measures as high temperatures persist and climate change drives higher heat.
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.
Multiple football figures have disclosed probable or suspected CTE linked to repeated head impacts. Reports show higher dementia and neurodegenerative risks among players, fueling debates over heading guidelines and player support. Authorities and unions are urged to strengthen concussion protocols and youth-heading rules as more cases surface.
Recent reporting shows chronic inflammation is linked to aging disorders such as cancer and Alzheimer’s. Studies indicate inflammation may be a cause, not just a symptom, of broad health risks. Policy and lifestyle factors are under scrutiny as researchers push for preventative strategies.
Researchers have examined brains from 235 former NFL players who died between 2016 and 2021 and have confirmed chronic traumatic encephalopathy (CTE) in 215. Including all 878 players who died in that period, the team has calculated a conservative minimum prevalence of CTE of 24.5% at death and urged prevention to cut repetitive head impacts.
The FDA has cleared four blood tests to help diagnose Alzheimer's in people with memory problems, a move that could speed access to therapies. Experts caution that tests are not for asymptomatic individuals, and many questions remain about accuracy. Readers are advised to focus on brain-healthy risks like blood pressure, diabetes and smoking.
