AI brain implants allow paralyzed man to regain use of arms, hands, fingers
Editor's Note In a first of its kind surgical procedure, doctors have installed artificial intelligence (AI) implants in the brain of a 46-year-old man who was paralyzed from a fall on the ice, CNN September 27 reports. The AI implant formed a "digital bridge"–an idea pioneered by the French neuroscientist…
Study: Physical fitness helps bolster older adult brains
Editor's Note Research by the Center for Longevity at the University of Texas, Dallas, suggests that older adults who engage in intensive fitness practices tend to have brains that more closely resemble those of younger adults, the August 23 UTDallas News reports. The study, which compared high-fit older adults (median…
Study: Can a mild case of COVID-19 change your brain?
Editor's Note Those who experience anxiety and depression months after a mild case of COVID-19 may have brain changes that affect its function and structure, finds a study that will be presented at the American Academy of Neurology’s Annual Meeting in April. The study, by researchers at the University of…
Study: Gum bacteria may be linked to Alzheimer’s disease
Editor's Note A June 2022 study, titled “The Periodontal Pathogen Fusobacterium nucleatum Exacerbates Alzheimer’s Pathogenesis via Specific Pathways” and published by Frontiers in Aging Neuroscience, found that Fusobacterium nucleatum (F. nucleatum), a common bacteria associated with oral conditions, may be linked to Alzheimer’s disease, HealthLine July 19 reports. According to…
