Introduction: Neuroimaging has expanded our understanding of pediatric brain disorders in which white matter organization and connectivity are crucial to functioning. Paralleling the known pathobiology of many neurodevelopmental disorders, traumatic brain injury (TBI) in childhood can alter trajectories of brain development. Specifically, diffusion tensor imaging (DTI) studies in TBI have demonstrated white matter (WM) abnormalities that suggest microstructural disruptions that may underlie atypical neurodevelopment.

- Privilege and marginalization based on racial background contribute to disparities in care and recovery for Black athletes facing sport-related concussions (SRC).
- A qualitative content analysis was performed to explore existing literature on racial differences in SRC outcomes, revealing biased beliefs and limited access to concussion resources for Black athletes.
- The study developed a novel ecological-systems framework to illustrate how broader socio-cultural and historical factors influence individual clinical decisions and care for Black athletes with SRC.
Deficits in memory performance have been linked to a wide range of neurological and neuropsychiatric conditions. While many studies have assessed the memory impacts of individual conditions, this study considers a broader perspective by evaluating how memory recall is differentially associated with nine common neuropsychiatric conditions using data drawn from 55 international studies, aggregating 15,883 unique participants aged 15-90. The effects of dementia, mild cognitive impairment, Parkinson's disease, traumatic brain injury, stroke, depression, attention-deficit/hyperactivity disorder (ADHD), schizophrenia, and bipolar disorder on immediate, short-, and long-delay verbal learning and memory (VLM) scores were estimated relative to matched healthy individuals.

This study used Bayesian analyses to characterize and compare TBI and biopsychosocial risk factors among 632 siblings (207 NDC, 425 controls; mean age 20.54 years, range 10-30, 78.

Objective: To examine the association of self-reported premorbid anxiety/depression symptoms in collegiate student-athletes with (1) recovery times until asymptomatic, (2) return-to-play, and (3) postconcussion symptom burden.
