To Err is Human: “Abnormal” Neuropsychological Scores and Variability are Common in Healthy Adults
TL;DR: It is concluded that abnormal performance on some proportion of neuropsychological tests in a battery is psychometrically normal, and that test battery developers provide data on the amount of variability in normal samples and also provide base rate tables with false positive rates that can be used clinically when interpreting test performance.
Journal ArticleDOI
Grade 1 or “Ding” Concussions in High School Athletes
TL;DR: The data suggest that current grade 1 return-to-play recommendations that allow for immediate return to play may be too liberal and a reconsideration of current concussion grading systems appears to be warranted.
Journal ArticleDOI
Validity of ImPACT for measuring processing speed following sports-related concussion.
TL;DR: It appears as if the Processing Speed Composite, Reaction Time Composite, and SDMT are measuring a similar underlying construct in this sample of concussed amateur athletes.
Journal ArticleDOI

Justin E. Karr,Corson N. Areshenkoff,Philippe Rast,Scott M. Hofer,Grant L. Iverson,Mauricio A. Garcia-Barrera +5 more
TL;DR: Results show some evidence for greater unidimensionality of executive function among child/adolescent samples and both unity and diversity among adult samples, but low rates of model acceptance/selection suggest possible bias toward the publication of well-fitting but potentially nonreplicable models with underpowered samples.
Journal ArticleDOI
‘Postconcussive’ symptoms in persons with chronic pain
TL;DR: It is illustrated that postconcussive-like symptoms are not unique sequelae of mild head injury, and the presence of chronic pain should be considered when interpreting patients' physical, cognitive, and psychological complaints following closed head injury.
