- Virginia State Police issue senior alert for missing Portsmouth man
Virginia State Police have issued a senior alert for 68-year-old Arthur Andrew Fladger, who was last seen in Portsmouth, VA on Saturday afternoon. Fladger suffers from a cognitive impairment.
- A neurologist says 'super movers' have younger brains — here's how to reap the benefits yourself
A neurologist's research suggests that 'super movers'—older adults who walk briskly—have younger brains and lower risks of cognitive decline and disease. Dr. Joe Verghese's studies indicate that maintaining a fast walking pace after 80 correlates with better memory, mood, and reduced biological aging.
- 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.
- HER2-Positive Breast Cancer and Brain Metastases
HER2-positive breast cancer patients have a 20% to 40% risk of developing brain metastases, which are associated with reduced survival rates and neurological complications such as headaches, seizures, and cognitive impairment.
- In prisons and jails, a lack of sleep may harm health and safety
A report from the University of Texas at Austin's Prison and Jail Innovation Lab highlights that sleep disruption in U.S. prisons and jails, caused by factors like noise and overnight head counts, harms physical and mental health, increases facility tensions, and poses risks to staff. The report recommends policy changes such as reducing nighttime disruptions and improving bedding to address chronic sleep deprivation.
- Woman with advanced Alzheimer's regained speech and memories after taking magic mushrooms
A Japanese American woman with advanced Alzheimer's disease showed significant improvements in speech, mobility, and memory after taking psilocybin-containing mushrooms in a case study published in Frontiers in Neuroscience. The study notes limitations due to being a single-patient case without controls or long-term follow-up.
- Brain Risks Tied to High Ultraprocessed Food Intake
A study found that high consumption of ultraprocessed foods, such as sugar-sweetened drinks, packaged snacks, and processed meats, is linked to an increased risk of developing dementia or cognitive impairment. The analysis focused on a composite outcome of these cognitive health issues.
- Ultraprocessed foods may be linked with dementia risk, study finds
A new study links ultra-processed foods to a 58% higher dementia risk and 46% increased cognitive impairment risk in older adults, according to CBS News medical correspondent Dr. Céline Gounder.
- Everyday task may help detect early dementia signs before diagnosis, study finds
A study in Portugal found that analyzing writing patterns, such as pauses and stroke organization, could detect early signs of cognitive impairment in older adults before traditional tests. Researchers used a digital tablet to track hand movements during writing exercises, revealing slower and fragmented writing in those with cognitive decline during dictation tasks.
