Sports Concussion: Beyond the Sideline Evaluation
A normal CT scan does not mean a normal brain. Most sports concussions produce diffuse axonal injury, metabolic crisis, and neuroinflammation that standard emergency imaging was never designed to detect. If your athlete is still symptomatic weeks later, the injury is real—it just hasn’t been properly measured.
The Concussion Your Emergency Room Missed
Here is what happens after most sports concussions. The athlete gets hit. A sideline evaluation is performed—symptom checklist, balance test, maybe a SCAT5. If symptoms persist, the athlete goes to an emergency department. A CT scan comes back normal. The patient is sent home with instructions to rest and follow up with their primary care physician if symptoms don’t improve.
This protocol is designed to rule out neurosurgical emergencies—bleeds, skull fractures, midline shift. It accomplishes that goal. What it does not do is evaluate the actual concussion injury: the diffuse axonal shearing that disrupts white matter tracts, the acute metabolic crisis that starves neurons of energy, and the inflammatory cascade that prolongs recovery for weeks or months. CT imaging is not sensitive to any of these. McCrory et al., in the 2017 Consensus Statement on Concussion in Sport, acknowledged that “conventional structural neuroimaging is typically normal in concussion.”
The result is a population of athletes—youth, collegiate, professional, and recreational—who are told their brain is fine when it is not. They are cleared to return to play based on symptom resolution rather than neurological recovery. They accumulate additional impacts on a brain that has not yet healed. And when symptoms become chronic, they are often dismissed or attributed to psychological factors rather than the structural and metabolic injury that is actually driving them.
Cumulative Damage: Why Every Hit Counts
The conversation about sports concussion has shifted substantially over the past fifteen years, driven in large part by the neuropathological work of McKee et al. (2009, Journal of Neuropathology & Experimental Neurology). Their examination of brains from athletes with histories of repetitive head trauma revealed chronic traumatic encephalopathy (CTE)—a progressive tauopathy characterized by perivascular accumulation of hyperphosphorylated tau protein in patterns distinct from Alzheimer’s disease.
What made this finding particularly significant was the discovery that CTE pathology was present not only in professional athletes with documented concussion histories but also in younger athletes whose exposure consisted primarily of subconcussive impacts—the routine hits that occur in practice and competition and never trigger clinical evaluation. Bailes et al. (2013, Neurosurgery) estimated that a high school football lineman sustains between 600 and 1,000 subconcussive head impacts per season.
Each impact, whether it meets the clinical threshold for concussion or not, produces some degree of axonal strain, blood-brain barrier disruption, and microglial activation. When these insults accumulate faster than the brain can repair them, the neurological burden compounds. The metabolic reserve narrows. The threshold for the next symptomatic concussion drops. Recovery from each successive injury takes longer.
This is why parents, coaches, and athletes need to understand that concussion management extends beyond the single-event model. The relevant question is not just “did they get a concussion?” but “what is the cumulative state of this brain?” Answering that question requires diagnostic tools that go far beyond a sideline screening.
How We Actually Evaluate a Concussion
At The Neurogenesis Project, Dr. Orr evaluates sports concussion the way a neurologist should—by measuring the injury rather than simply cataloging symptoms. Our evaluation begins with a comprehensive neurological examination and proceeds through three diagnostic pillars.
Advanced Neuroimaging. We use MRI sequences specifically sensitive to concussion pathology—diffusion tensor imaging to evaluate white matter tract integrity, susceptibility-weighted imaging to detect microhemorrhages, and volumetric analysis to identify regional atrophy. These sequences detect injuries that are invisible on the standard CT and routine MRI protocols used in emergency departments and most outpatient settings.
Cognitive Testing with Normative Comparison. We perform validated neuropsychological assessments that measure processing speed, reaction time, working memory, executive function, and attention. Results are compared against age- and education-matched normative data to identify deficits that fall outside expected performance ranges—deficits that an athlete may not recognize because they have no baseline awareness of their own decline.
Metabolic and Inflammatory Biomarkers. Concussion triggers a neuroinflammatory cascade. We measure inflammatory cytokines, oxidative stress markers, and metabolic indicators that reflect the current state of the brain’s recovery. These labs tell us whether the metabolic crisis is resolving or persisting, regardless of what the symptom checklist says.
Together, these three pillars produce an objective picture of brain health—one that supports informed decisions about treatment, recovery timelines, and return to play.
How We Treat This
Treatment is built from diagnostic findings, not applied as a generic concussion protocol. Each intervention targets a specific dimension of the injury.
NAD+ IV Therapy
Addresses the acute metabolic crisis at the center of concussion pathophysiology. Restores the coenzyme required for mitochondrial ATP production in neurons operating under increased energy demand with reduced metabolic capacity.
Exosome Therapy
Delivers anti-inflammatory signaling molecules and neurotrophic factors that cross the blood-brain barrier. Targets the microglial activation and neuroinflammatory cascade that sustains post-concussion symptoms beyond the acute phase.
Advanced Neuroimaging
MRI sequences designed for concussion pathology—DTI, SWI, and volumetric analysis—reveal white matter injuries, microhemorrhages, and structural changes that standard imaging protocols miss entirely.
Brain Health Lab Panels
Inflammatory biomarkers, oxidative stress indicators, and metabolic panels that quantify the brain’s recovery state. Objective data that informs treatment decisions and return-to-play timing.
NeuroCoaching
Dr. Edwards works with athletes on structured cognitive recovery strategies, sleep optimization, and graduated return-to-activity protocols calibrated to objective neurological findings rather than symptom checklists alone.
Glutathione IV Therapy
The brain’s primary endogenous antioxidant. IV glutathione directly combats the oxidative stress that concussion produces, protecting neurons from secondary damage during the vulnerable post-injury recovery window.

Our comprehensive TBI program addresses moderate-to-severe brain injuries from all causes—motor vehicle accidents, falls, blast exposure, and high-severity sports impacts that extend beyond the concussion spectrum.
Headache & Migraine Treatment
Post-concussive headache is one of the most persistent symptoms after sports injury. Our headache program uses nerve blocks, chemodenervation, and metabolic therapies to address the underlying neurology.

Your Athlete Deserves a Real Evaluation
A normal CT does not mean a normal brain. If your athlete is still struggling after a concussion—or has a history of multiple head impacts—the injury needs to be measured, not guessed at. Dr. Orr at The Neurogenesis Project provides the advanced diagnostic workup that sideline evaluations and emergency departments are not designed to deliver.
