About The Study: Using Fitbit data in a longitudinal cohort of 3,393 young adolescents, 6 sleep health dimensions were identified: irregularity, timing, duration, social jetlag, weekend oversleep, and continuity. Greater irregularity was associated with higher concurrent transdiagnostic mental health symptoms, whereas shorter duration was associated with higher symptoms at 1-year follow-up. These findings demonstrate the multidimensional nature of adolescent sleep health and can help guide selection of sleep health domains and representative measures to enhance reproducibility and suggest potential intervention targets.

About The Study: This systematic scoping review study of prescription drug promotion by influencers found that such promotion carried risks of inaccurate or misleading advice, often amplified through personal and emotionally resonant narratives in an environment with limited oversight and enforcement. Despite the small and fragmented evidence base, these findings highlight the urgent need for updated regulatory guidance, standardized and enforceable disclosure requirements, stronger platform accountability, and targeted digital literacy initiatives. Policymakers and researchers should act proactively to safeguard public health.

Multiple sclerosis (MS) has more than doubled in recorded prevalence in England from 2000 to 2020, increasing by 6% per year, largely due to improved diagnosis and longer life expectancy, finds a new study by University College London (UCL) and Imperial College London researchers.

Dr. Jeffrey Keller of Pennington Biomedical Research Center explores whether exercise and intensive cardiovascular risk reduction could improve cognitive function in older adults at risk for Alzheimer’s disease In a recent study, researchers found that exercise and aggressive cardiovascular risk reduction successfully improved heart health, but these efforts did not produce measurable cognitive benefits over two years in older adults at risk for Alzheimer's disease. In “Effects of Exercise and Intensive Vascular Risk Reduction on Cognitive Function in Older Adults - A Randomized Clinical Trial,” published in JAMA Neurology, researchers, including Dr. Jeffrey Keller of Pennington Biomedical Research Center, shared the results of the Risk Reduction for Alzheimer’s Disease (rrAD) study. They found that interventions that successfully improved cardiovascular health did not translate into measurable cognitive benefits over two years, highlighting a critical gap between vascular risk reduction and brain health.
