  • New methods to identify Alzheimer's drug candidates with anti-aging properties November 13, 2018
    Old age is the greatest risk factor for many diseases, including Alzheimer's disease (AD) and cancer. Geroprotectors are a recently identified class of anti-aging compounds. New research has now identified a unique subclass of these compounds, dubbed geroneuroprotectors (GNPs), which are AD drug candidates and slow the aging process in mice.
  • New insights into the aging brain November 12, 2018
    A group of scientists investigated why the choroid plexus contains so much more klotho than other brain regions.They showed that klotho functions as a gatekeeper that shields the brain from the peripheral immune system.
  • Alzheimer's and cardiovascular disease share common genetics in some patients November 9, 2018
    Genetics may predispose some people to both Alzheimer's disease and high levels of blood lipids such as cholesterol, a common feature of cardiovascular disease, according to a new study.
  • Patients with untreated hearing loss incur higher health care costs over time November 8, 2018
    Older adults with untreated hearing loss incur substantially higher total health care costs compared to those who don't have hearing loss -- an average of 46 percent, totaling $22,434 per person over a decade, according to a new study.
  • Skin ages when the main cells in the dermis lose their identity and function November 8, 2018
    A study in mice explains that dermal fibroblasts lose their cell identify over time and with it their capacity to produce and secrete collagen and other proteins.
  • New insights into the neural risks and benefits of marijuana use November 6, 2018
    Research released today underscores both the dangers and the therapeutic promise of marijuana, revealing different effects across the lifespan. Marijuana exposure in the womb or during adolescence may disrupt learning and memory, damage communication between brain regions, and disturb levels of key neurotransmitters and metabolites in the brain. In Alzheimer's disease, however, compounds found in […]
  • Artificial intelligence predicts Alzheimer's years before diagnosis November 6, 2018
    Artificial intelligence (AI) technology improves the ability of brain imaging to predict Alzheimer's disease, according to a new study.
  • Family tree of 400 million people shows genetics has limited influence on longevity November 6, 2018
    Although long life tends to run in families, genetics has far less influence on life span than previously thought, according to a new analysis of more than 400 million people. The results suggest that the heritability of life span is well below past estimates, which failed to account for our tendency to select partners with […]
  • Evidence of restored vision in rats following cell transplant November 5, 2018
    Researchers have discovered that neurons located in the vision centers of the brains of blind rats functioned normally following fetal retina cell transplants, indicating the successful restoration of vision.
  • Disrupted circadian rhythms may drive anxiety and exacerbate brain disorders November 5, 2018
    Sleep disruptions are associated with many brain disorders, including anxiety, dementias, and traumatic brain injury. While these disruptions are sometimes viewed as a side effect of brain disorders, new findings suggest that aberrant sleep-wake cycles can also drive brain pathology. The studies were presented at Neuroscience 2018, the annual meeting of the Society for Neuroscience […]
