Athletes with ADHD face higher concussion odds and longer recovery, a review finds

A review published 13 July in an MDPI sports-medicine journal argues that athletes with ADHD sustain concussions more often and take longer to recover from them than athletes without the condition — and that current return-to-play protocols mostly don't account for the difference [s1].

What kind of study this is, exactly

This is a literature review, not a new trial or dataset: authors Corbit Franks of the University of Mississippi, and Jeffrey Parr and Mary King of the University of Southern Mississippi, describe their goal as bringing "high-quality peer reviewed research into one singular review paper," synthesizing prior studies rather than collecting new data [s1]. That distinction matters for how much weight to put on the numbers below — a review is only as strong as the studies it draws on, and its value is in identifying a pattern across existing evidence, not in producing a new, independently verified data point.

The numbers the review reports

ADHD affects an estimated 4.2% to 8.1% of young athletes [s1]. Within that population, the review reports athletes with ADHD are 1.6 to 2.5 times more likely to sustain a concussion than athletes without ADHD, and that recovery — however it was measured across the underlying studies — took 4 to 6 days longer [s1]. Those are wide ranges (1.6 to 2.5 times, not a single point estimate), which itself signals that the underlying studies didn't agree closely on the exact size of the effect, even if they agreed on its direction.

Why the authors think this happens

The review's proposed explanation isn't that ADHD directly causes concussions or slows healing in some mechanical sense — it's that ADHD symptoms and concussion symptoms overlap heavily, which complicates both baseline testing and recovery assessment. Fatigue, sleep disruption, emotional volatility, and difficulty concentrating are common to both conditions, according to the review [s1]. That overlap creates two distinct problems: a baseline cognitive test given to an athlete with untreated ADHD may already look impaired before any head injury occurs, making post-injury changes harder to detect accurately; and self-reported symptom checklists used to clear an athlete to return to play may stay elevated for ADHD-related reasons even after the concussion itself has resolved, or mask genuine lingering injury under a pre-existing symptom baseline.

The authors argue this has direct practical consequences: "Return-to-learn strategies and return-to-play protocols may need to look completely different" for athletes with ADHD, and "recognizing ADHD as a modifier can lead to more accurate diagnoses, better symptom interpretation" [s1].

What the review doesn't establish

Because this is a synthesis of existing literature rather than a new controlled study, it can't independently verify the 1.6-to-2.5-times figure or the 4-to-6-day gap — those numbers are only as reliable as the original studies that produced them, and the review as covered doesn't detail how consistent methodology was across those source studies. It also doesn't establish causation: the overlap-in-symptoms explanation is the authors' proposed mechanism, not something the review itself tested directly. Readers should treat this as a credible signal that ADHD deserves more attention in concussion protocols, not as a settled, precisely-quantified risk multiplier.

What to watch next

Whether sports medicine organizations that write return-to-play guidelines — the kind used by high school and college athletic trainers — begin incorporating ADHD status as an explicit variable in baseline testing and clearance decisions, and whether future prospective studies (tracking athletes forward in time, rather than reviewing past research) can narrow the wide risk-multiplier range this review reports.
