- One walking habit could signal a healthier brain after 80, scientists say
A study by Stony Brook Medicine found that older adults who walk significantly faster than peers (classified as 'super movers') have about half the risk of cognitive decline. These individuals maintained cognitive function despite similar brain pathologies as slower walkers, suggesting resilience mechanisms may protect brain health. The observational study, published in Neurology, emphasizes physical activity as a key factor in healthy aging but notes it does not prove faster walking prevents dementia.
- Quitting smoking could offer a major benefit beyond heart and lung health, study finds
A 25-year study of 32,000 adults found that quitting smoking reduces dementia risk, with former smokers showing similar risk levels to never-smokers after seven years. Researchers noted that longer periods of being smoke-free correlated with lower dementia risk, and benefits were strongest for those who avoided weight gain post-quitting.
- Doctors said my dizzy spells were just panic attacks - it turned out to be the early warning sign of a paralysing nerve condition that's hitting thousands of healthy young people like me
A young person experienced dizzy spells misdiagnosed as panic attacks, later found to be an early warning sign of a paralyzing nerve condition affecting thousands of healthy young individuals. The condition is impacting many young people. Early diagnosis is crucial for effective treatment.
- I ignored my itchy legs and common sleep complaint. Then doctors found something horrifying on a scan. I'd left it far too late
The author ignored their itchy legs and sleep complaints, but a scan revealed a horrifying condition. The condition was discovered too late, implying severe consequences. The article hints at a serious health issue that could have been prevented with earlier attention.
- Experts pinpoint the exact heartbeat ranges that signal stroke risk... how does YOURS measure up?
Experts have identified specific heartbeat ranges that indicate a risk of stroke, allowing individuals to assess their own risk. The study provides valuable insights into the prevention and detection of strokes. Further research is needed to confirm the findings.
- A tool to help keep dementia in check
A new tool called the Brain Care Score demonstrates that lifestyle changes can reduce dementia risk, challenging the belief that family history guarantees the condition. The article discusses an interview with neurologist Dr. Jonathan Rosand and NPR correspondent Allison Aubrey.
