Irvine, Calif., June  21, 2021 — A large-scale meta-analysis led by University of California, Irvine researchers provides the strongest evidence yet of which blood pressure medications help slow memory loss in older adults: those that can travel out of blood vessels and directly into the brain. The findings, published in the American Heart Association journal Hypertension, will be of interest to the 91 million Americans whose blood pressure is high enough to warrant medication, as well as the doctors who treat them.

Memory Biomarkers Confirm Aerobic Exercise Helps Cognitive Function in Older Adults
Florida Atlantic University

Until now, systemic biomarkers to measure exercise effects on brain function and that link to relevant metabolic responses were lacking. A study shows a memory biomarker, myokine Cathepsin B (CTSB), increased in older adults following a 26-week structured aerobic exercise training. The positive association between CTSB and cognition, and the substantial modulation of lipid metabolites implicated in dementia, support the beneficial effects of exercise training on brain function and brain health in asymptomatic individuals at risk for Alzheimer’s.

Imbalance Between Certain Personality Traits in Teens May Raise the Risk for Binge Drinking in Early Adulthood
Research Society on Alcoholism

Teens with high sensation seeking impulses and relatively low cognitive control are at elevated risk for binge drinking in early adulthood, a new study suggests. Young adults aged 18–25 report the highest rates of binge drinking in the previous month, a pattern that predicts later Alcohol Use Disorder (AUD) and other problem health behaviors. Two personality traits that evolve during adolescence and early adulthood — sensation seeking, the tendency to pursue novelty and excitement, and cognitive control, thinking before acting — are known to be related to binge drinking, or heavy episodic drinking (HED). Models of risky behavior among teens suggest that an imbalance involving higher sensation seeking and less-developed cognitive control may drive problem alcohol use. The study, in Alcoholism: Clinical & Experimental Research, examined this imbalance over time as adolescents became young adults, and whether it was associated with binge drinking. Understanding these dynamic risk factors
