  • Psychological distress is a risk factor for dementia January 17, 2019
    A new study suggests that vital exhaustion -- which can be perceived as an indicator of psychological distress -- is a risk factor for future risk of dementia.
  • Common gene disorder causes serious 'stealth' disease, but could be easily treated January 16, 2019
    The western world's most common genetic disorder is a 'stealth condition' that causes far higher levels of serious disease and disability than previously thought, despite being easy to detect and treat.
  • New AI can detect urinary tract infections January 16, 2019
    New AI could identify and help reduce one of the top causes of hospitalization for people living with dementia: urinary tract infections (UTI).
  • Gene-editing tool CRISPR/Cas9 shown to limit impact of certain parasitic diseases January 15, 2019
    Researchers have successfully used CRISPR/Cas9 to limit the impact of schistosomiasis and liver fluke infection, which affects more than a quarter of a billion people in Southeast Asia, sub-Saharan Africa, and Latin America.
  • MANF identified as a rejuvenating factor in parabiosis January 15, 2019
    Older mice who are surgically joined with young mice in order to share a common bloodstream get stronger and healthier, making parabiosis one of the hottest topics in age research. Researchers now report that MANF (mesencephalic astrocyte-derived neurotrophic factor) is one of the factors responsible for rejuvenating the transfused older mice. Researchers also show the […]
  • Stroke drug may also prevent Alzheimer's disease January 15, 2019
    Researchers have discovered that a drug currently being developed to treat stroke patients could also prevent Alzheimer's disease. The study shows that the genetically engineered protein 3K3A-APC protects the brains of mice with Alzheimer's-like symptoms, reducing the buildup of toxic peptides and preventing memory loss.
  • Dementia: New culprit and potential treatment target January 14, 2019
    A study shows people with the worst memory problems also had the most leakage in their brain's blood vessels -- regardless of whether abnormal proteins amyloid and tau were present.
  • Targeting an RNA-binding protein to fight aging January 10, 2019
    Researchers have found that the RNA-binding protein PUM2 contributes to the accumulation of defective mitochondria, a key feature of the aging process. Targeting PUM2 in old animals protects against age-related mitochondrial dysfunction.
  • Decreased deep sleep linked to early signs of Alzheimer's disease January 9, 2019
    Researchers have uncovered part of the explanation for why poor sleep is linked to Alzheimer's disease. They found that older people who have less slow-wave sleep -- the deep sleep you need to consolidate memories and wake up feeling refreshed -- have higher levels of the brain protein tau. Elevated tau is a sign of Alzheimer's disease […]
  • Older people who use hearing aids still report hearing challenges January 7, 2019
    A high proportion of older people with hearing aids, especially those with lower incomes, report having trouble hearing and difficulty accessing hearing care services, according to a new study.
