Statins are a key medication for the prevention of atherosclerotic cardiovascular disease, a specific type of cardiovascular disease caused by the buildup of fatty plaque (atherosclerosis) inside the arteries. https://medicalxpress.com/news/2026-08-adults-older-statins-similar-year.html Wed, 12 Aug 2026 11:40:09 EDT news705746206 Dementia after age 90: Study clarifies who may be at higher risk It may seem natural to assume that people experience cognitive decline after age 90, but until recently, researchers had limited evidence about how advanced age affects the brain. This major knowledge gap will need to be addressed as people live longer. By 2100, there could be around 230 million people 90 or older on Earth. As a result, scientists, clinicians and policymakers are seeking more information to help them support this expanding demographic. https://medicalxpress.com/news/2026-08-dementia-age-higher.html Wed, 05 Aug 2026 16:20:04 EDT news705160802 Blocking a mitochondrial transporter may curb inflammation from 'zombie' cells without killing them Researchers have uncovered a previously unknown mechanism that helps aging cells drive the chronic inflammation linked to many age-related diseases. The findings reveal how dysfunctional mitochondria—the cell's energy-producing structures—work with the cell's epigenetic machinery to switch on inflammatory genes, opening the door to a new therapeutic approach for promoting healthier aging. https://medicalxpress.com/news/2026-07-blocking-mitochondrial-curb-inflammation-zombie.html Wed, 29 Jul 2026 16:20:01 EDT news704555882 Portable air filters don't cut infection rates in care homes, study finds Portable air filters made no difference to rates of respiratory and other infections in older people's long-term care facilities, a University of Bristol–led trial published in JAMA Internal Medicine has found. The study's authors advise long-term care facilities to continue with standard infection-control measures, including vaccines.
