Neuropsychiatric Genetic Risk Mapped Fluid and Crystallized Cognition

Neuropsychiatric Genetic Risk Mapped Fluid and Crystallized Cognition

TL;DR: A 2026 study in Nature Communications found that neuropsychiatric disorder risk did not map onto cognition as one general trait. Schizophrenia, bipolar disorder, ADHD, autism, and Alzheimer’s disease showed different genetic links with reaction time, fluid reasoning, crystallized knowledge, and noncognitive educational skills. Key Findings 439,000-person GWAS scale: The crystallized-knowledge genome-wide association study had …

GLP-1RAs Linked to Lower Heart Failure Risk in Obstructive Sleep Apnea

GLP-1RAs Linked to Lower Heart Failure Risk in Obstructive Sleep Apnea

TL;DR: A 2026 real-world study in Journal of Clinical Sleep Medicine found that glucagon-like peptide-1 receptor agonist use was associated with lower 3-year cardiovascular-event risk in adults with obesity and obstructive sleep apnea. Key Findings 18,523 matched pairs: Propensity matching compared GLP-1 receptor agonist users with similar non-users who had obesity and obstructive sleep apnea. …

EMS Plus Low-Intensity Resistance Exercise Improved Inhibitory Control

EMS Plus Low-Intensity Resistance Exercise Improved Inhibitory Control

TL;DR: A 2026 crossover study in Clinical Physiology and Functional Imaging found that adding electrical muscle stimulation to low-intensity resistance exercise improved inhibitory control in young men, while stimulation alone showed a delayed 15-minute benefit. Key Findings 17 young men: Participants completed low-intensity resistance exercise, electrical muscle stimulation alone, and combined low-intensity exercise plus stimulation …

COMBAT-ICU Cognitive Training Reduced PICS Severity in Pilot Trial

COMBAT-ICU Cognitive Training Reduced PICS Severity in Pilot Trial

TL;DR: A 2026 pilot randomized trial in Nursing in Critical Care found that an 8-week home-based program combining exercise with computerized cognitive training was feasible in 36 ICU survivors and produced larger reductions in patient-reported post-intensive care syndrome severity than attention control, while exploratory cognitive and quality-of-life effect sizes generally favored the combined program over …
