An Exercise-Induced Hormone Might Help Protect Against Alzheimer`sFRIDAY, Sept. 8, 2023 (HealthDay News) -- Therapies based on a hormone people make while exercising may be the next frontier in treating Alzheimer’s disease, according to a new study.Researchers have found that the exercise-induced hormone irisin may reduce both the plaque and the tau tangles characteristic of the disease.Before this, this same team developed the first 3D human cell culture models of Alzheimer’s disease, which it was able to use in this new research into the impact of irisin on amyloid beta in the brain.Physical exercise had already been shown to reduce amyloid beta deposits in mouse models of Alzheimer’s, but it wasn’t clear how.The increase of circulating levels of the muscle-derived hormone irisin through exercise regulates glucose and lipid metabolism in...

Autopsy Study of Athletes Who Died Young Shows Many Had Signs of CTETUESDAY, Aug. 29, 2023 (HealthDay News) -- The degenerative brain disease known as chronic traumatic encephalopathy (CTE) may be striking some at much younger ages than thought possible: New research has uncovered early signs of the condition in amateur athletes who died young after playing contact sports.The troubling finding was discovered during the brain autopsies of 152 athletes. All had engaged in the type of sports, such as football, where head impacts are routine. And all had died before turning 30.Investigators determined that roughly 4 in 10 had developed early signs of CTE while still in their teens and 20s. And the vast majority of those with CTE — more than 70% — were just young amateurs, not professional players.“CTE is a neurodegenerative disease caused by...

`Couch Potato` Childhoods Could Mean Heavier, Less Healthy Hearts LaterWEDNESDAY, Aug. 23, 2023 (HealthDay News) -- Children need to get up off the sofa and move more, according to a new study that linked childhood sitting time with heart damage in young adulthood. That was true even when the adult's blood pressure and weight were healthy, according to researchers.“All those hours of screen time in young people add up to a heavier heart, which we know from studies in adults raises the likelihood of heart attack and stroke,” said study author Dr. Andrew Agbaje, of the University of Eastern Finland in Kuopio. “Children and teenagers need to move more to protect their long-term health,” he explained in a news release from the European Society of Cardiology. This was the first study to investigate the cumulative effect of smartwatch-assessed sedentary...
