HAMILTON, Ontario — The human body is very much the sum of its parts. If one bodily area is out of whack, it’s very likely that other organs and processes will have a problem as well. Case in point, researchers from McMaster University report higher levels of body fat are a risk factor for cognitive decline, slower thought processing speed, and memory issues.
Even after the research team accounted for cardiovascular risk factors, like diabetes or hypertension, and vascular brain injuries, the result stayed consistent. There was an undeniable association between body fat and lower cognitive scores. This strongly indicates there are additional, but still unclear pathways connecting excessive fat buildup to cognitive decline.
A new article, conducted by Lili Zang and colleagues from Weifang Medical University School of Nursing in Shandong Province, China, discusses a meta-analysis of 15 high-quality trials that investigated the impact of light therapy on individuals with Alzheimer’s disease (AD). The meta-analysis included 598 patients with mild to moderate Alzheimer’s disease, and it covered 15 randomized controlled trials conducted in seven different countries. Those trials were published between 2005 and 2022. Sleep Improvement Light therapy led to significant improvements in several sleep measures. It notably enhanced sleep efficiency, increased interdaily stability, and reduced intradaily variability, all of which are indicators of better sleep quality. Light therapy was associated with a reduction in agitation, depression, and caregiver burden among individuals with Alzheimer’s disease. A significant advantage over usual care was shown in reducing the severity of psychobehavioral symptoms, as assessed...
