This study examined linear nonlinear trends physical, cognitive, over the entire adult lifespan.Cross-sectional data were obtained from 1,546 individuals aged 21-100 years, selected using random digit dialing for Successful AGing Evaluation (SAGE) study, a structured multicohort investigation that included telephone...

Abstract Purpose Non‐benzodiazepine receptor agonists (nBZRAs) were developed as an alternative to benzodiazepines (BZDs) treat insomnia. Little is known about how the introduction of nBZRAs influenced trends in BZD prescribing. We examined and nBZRA prescribing from 1993 2010. Methods used National Ambulatory Medical Care Survey examine 516,118 patient visits between categorized BZD, nBZRA, or + based on medications prescribed each visit applied linear probability regression models assess...

The Insomnia Severity Index (ISI) is a widely used self-report measure of insomnia symptoms. However, to date this has not been validated or well-characterized in veterans who have experienced traumatic brain injury (TBI).
