Article Synopsis
- * A study analyzed 174,878 student-athletes to assess the frequency of low scores on a concussion management test (ImPACT) for those with self-reported ADHD and/or LD, comparing them to a control group without these disorders.
- * Results indicated that student-athletes with LD frequently scored low on the ImPACT (30-37%) and those with both ADHD and LD also showed significant low scoring rates (24-31%), highlighting the need for better understanding of these conditions in concussion assessments.
Objective: To examine the prevalence of traumatic brain injury (TBI) in the US veteran population, and physical, mental, and cognitive health conditions associated with TBI.
Design: Retrospective cohort study.
Setting: A nationally representative sample of US military veterans surveyed in 2019-2020.
Objective: Veterans with a history of blast-related mild traumatic brain injury (mTBI) and posttraumatic stress disorder (PTSD) may be at risk for greater cognitive concerns and worse functional outcomes compared to those with either condition in isolation. However, traditional neuropsychological assessment approaches have yielded equivocal results in these populations. The present study examined an alternative method for detecting subtle cognitive inefficiencies: neurocognitive intraindividual variability (IIV), a measure of within-person performance consistency.

Research Method/design: Women survivors of IPV with and without IPV-related brain injuries were recruited online through Prolific ( = 205, = 39.8 ± 11.
