Concussion Characteristics in Adults With ADHD Seen in a Specialty Concussion Clinic.

Background: Concussions are a prevalent health concern, affecting millions of individuals in the United States yearly. Concussion symptomology overlaps with other conditions making diagnosis and management particularly challenging, particularly among individuals with ADHD. ADHD is a neurodevelopmental disorder that affects a significant portion of the adult population.

Repetitive Head Impacts in Youth Football: Description and Relationship to White Matter Structure.

Background: Few studies have examined white matter with diffusion tensor imaging in 8- to 12-year-old collision sport (CS) athletes.

Hypothesis: Youth CS athletes will demonstrate change in brain fractional anisotropy (FA) after a season of CS compared with an age-matched noncollision sport (NCS) cohort, and the number, magnitude, and location of hits will correlate with changes in the brain determined via FA for CS athletes.

Study Design: Prospective cohort study.
