  • CTE Is Not a Concussion: What Athletes and Parents Need to Know with Dr. Reece Granger | E81

    CTE Is Not a Concussion: What Athletes and Parents Need to Know with Dr. Reece Granger | E81
    Oct 19 2026
    Does having multiple concussions mean you're at risk for CTE? What is the difference between a concussion, repetitive head impacts, and chronic traumatic encephalopathy (CTE)? In this episode of Life After Impact: The Concussion Recovery Podcast, I welcome Dr. Reece Granger, host of Headfirst: The Concussion Podcast, chiropractor, and PhD researcher studying sports-related concussions in Australia's National Rugby League. We cover the science of concussion versus CTE, repeated head injuries, subconcussive impacts, long-term brain health, and concussion prevention in professional and youth sports. We examine how media coverage of NFL concussions and CTE can create confusion and unnecessary fear, why concussion protocols and return-to-play guidelines continue to evolve, and what athletes, parents, and healthcare professionals need to understand about the long-term risks of contact sports.CTE Is Not the Same Thing as a ConcussionOne of the most important discussions in this episode addresses a widespread misconception: having a concussion does not mean someone will develop CTE.Chronic traumatic encephalopathy is a neurodegenerative condition associated with prolonged exposure to repetitive head impacts, including impacts that may never produce recognizable concussion symptoms.We examine how the media has shaped public understanding of CTE, a topic that Dr. Granger has been analyzing as part of his PhD, including the influence of the movie Concussion, starring Will Smith.Are Changes to Sports Rules Actually Preventing Concussions?Drawing on his research into Australia's National Rugby League, Dr. Granger discusses the evolution of concussion protocols and the unintended consequences of certain rule changes.While some modifications have successfully reduced dangerous head impacts, others may shift the risk from one athlete to another.The conversation explores the challenges of protecting athletes without fundamentally changing the sports they love, including:The benefits of restricting heading in youth soccer and body checking in youth hockey.Why protecting the ball carrier in rugby can sometimes increase concussion risk for the tackler.How concussion incidence statistics may change as recognition and reporting improve.Whether professional athletes can truly provide informed consent to the long-term neurological risks of contact sports.Why sports organizations have a responsibility to protect athletes even when those athletes willingly accept the risks of competition.Concussion Myths That Still Influence Medical CareDespite decades of research, outdated concussion advice continues to circulate.Dr. Granger and I discuss several misconceptions that can interfere with appropriate concussion management, including the belief that someone must lose consciousness to sustain a concussion, outdated concussion grading systems, and the recommendation to remain in a dark room until symptoms disappear.Another fascinating discussion focuses on why concussion symptoms sometimes appear hours or days after an injury. Could adrenaline temporarily mask symptoms? Or are neurological changes continuing to unfold during the first 24–48 hours? The conversation highlights why concussion assessment and recovery are more complicated than a single examination or symptom checklist.Who Is Responsible for Protecting Professional Athletes?Professional athletes are trained to push through pain, compete under pressure, and prioritize performance. But what happens when the injury affects the very organ responsible for judgment, awareness, and decision-making? Dr. Granger challenges the expectation that athletes should always recognize and report their own concussion symptoms.He also raises important questions about the responsibilities of professional sports organizations, the long-term consequences of repetitive head trauma, and what happens to athletes and their families after retirement.Moving Beyond Fear Toward Better Concussion EducationFor individuals recovering from a concussion, headlines about CTE can be frightening. But understanding the distinction between concussion, persistent post-concussion symptoms, repetitive head-impact exposure, and neurodegenerative disease is essential.A history of concussion is not a diagnosis of CTE, and persistent concussion symptoms do not mean someone is developing a neurodegenerative condition.This conversation emphasizes the importance of interpreting emerging research carefully, challenging outdated medical advice, and providing athletes and patients with accurate information that supports informed decisions rather than unnecessary fear.Dr. Granger and I reflect on the role of podcasts in making concussion research accessible, allowing scientists and clinicians to explain the nuances that are often lost in sensationalized headlines.If you're an athlete, parent, coach, healthcare professional, or someone concerned about the long-term effects of multiple concussions, this episode offers an ...

  • Can Flying Make a Concussion Worse? Oxygen, Brain Injury, HBOT & Longevity Research with Dr. DeepSea | E80

    Can Flying Make a Concussion Worse? Oxygen, Brain Injury, HBOT & Longevity Research with Dr. DeepSea | E80
    Oct 12 2026
    FREE COPY of SHATTERED TO STRONG for veterans and active-duty military personnel. To request a copy, simply email info@ibum.org and include your branch of military service and how long you served.Can hyperbaric oxygen therapy (HBOT) help the brain recover after a concussion or traumatic brain injury (TBI)? And is it safe to fly after a concussion? Dr. Joseph Dituri, better known as Dr. DeepSea, returns to Life After Impact: The Concussion Recovery Podcast to discuss groundbreaking research into hyperbaric oxygen therapy for brain injury, post-concussion syndrome, neuroinflammation, brain healing, and longevity. A retired U.S. Navy commander, biomedical engineer, neuroscience researcher, and Guinness World Record holder, Dr. Dituri is involved in a major clinical trial at the University of South Florida investigating HBOT for traumatic brain injury. In this second interview with Dr. Ayla Wolf, he shares updates on the ongoing research, explains how changes in oxygen levels and atmospheric pressure affect human physiology, and explores whether alternating between high-oxygen and low-oxygen environments could improve brain function and healthy aging.Hyperbaric Oxygen Therapy: Where Does the Research Stand?Dr. Dituri provides an update on the University of South Florida's ongoing clinical trial investigating hyperbaric oxygen therapy in people with traumatic brain injury, including military veterans.While HBOT has demonstrated biological effects relevant to inflammation, tissue repair, and neuroplasticity, its effectiveness as a treatment for persistent post-concussion symptoms remains an active area of investigation.The research team is collecting extensive data, including EEG measurements, diffusion tensor imaging (DTI), blood biomarkers, and patient-reported symptoms.One of the biggest challenges? How do researchers objectively measure recovery from a traumatic brain injury when there is no universally accepted biological marker of recovery?Dr. Dituri discusses the difficulty of establishing meaningful clinical trial endpoints and why combining objective neurological measurements with patient-reported improvements may be essential for advancing concussion research.Is It Safe to Fly After a Concussion?One of the most interesting parts of this conversation addresses a question frequently raised by people recovering from concussion:Can flying make post-concussion symptoms worse?Commercial aircraft cabins are typically pressurized to the equivalent of approximately 6,000–8,000 feet above sea level. This means passengers experience changes in atmospheric pressure and oxygen availability, even while sitting comfortably inside an airplane.I ask Dr. Dituri about how these environmental changes might affect someone experiencing headaches, brain fog, dizziness, vestibular dysfunction, or other persistent concussion symptoms.They also discuss why the effects of a short domestic flight may differ from those of a long international flight—and why more research is needed to understand how recent brain injuries interact with altitude and cabin pressure.Importantly, there is not enough evidence to establish a universal waiting period before flying after an uncomplicated concussion. Individual medical circumstances and symptoms matter.Can Alternating Oxygen Levels Improve Brain Health and Longevity?Dr. Dituri has spent much of his career studying human physiology under extreme environmental conditions.Now, his research is expanding beyond brain injury recovery into healthy aging and longevity.As part of the XPRIZE Healthspan competition, his team is investigating a fascinating concept called hormesis—the idea that carefully controlled physiological stress may stimulate beneficial adaptations.Their research combines several interventions, including:Hypobaric exposure: Simulating higher-altitude environments with reduced atmospheric pressure and oxygen availability.Hyperbaric oxygen therapy: Increasing atmospheric pressure and oxygen exposure.Exercise: Challenging cardiovascular and metabolic systems.Cold-water immersion and sauna: Investigating physiological responses to controlled temperature stress.Red light therapy: Exploring photobiomodulation as another potential influence on cellular function.The goal is not simply to extend lifespan, but to improve healthspan—the years people maintain cognitive function, physical strength, balance, and independence.Dr. Dituri discusses the team's progress in the XPRIZE competition and why he believes the relationship between oxygen, physiological stress, and adaptation deserves further investigation.These combined interventions remain experimental, and their benefits for longevity have not yet been established.From Shattered to Strong: Finding a Path Forward After Brain InjuryDr. Dituri also introduces his new book, Shattered to Strong, inspired by his personal experience recovering from traumatic brain injury.His goal is to help people better understand the treatment ...

  • How Many Concussions Are Too Many? Measuring the Cumulative Impact on the Brain with Dr. Joseph Maroon | E79

    How Many Concussions Are Too Many? Measuring the Cumulative Impact on the Brain with Dr. Joseph Maroon | E79
    Oct 5 2026
    How many concussions are too many—and could we someday measure the cumulative effect of every hit to the head? Dr. Joseph Maroon, longtime team neurosurgeon for the Pittsburgh Steelers and a pioneer in concussion and traumatic brain injury research, joins Life After Impact to discuss multiple concussions, repetitive head impacts, subconcussive exposure, CTE, and the future of concussion testing. Dr. Maroon helped develop ImPACT, the neurocognitive test that transformed how the NFL, NHL, and other contact sports evaluate athletes after concussion. Now, his attention has turned to the next major problem in sports concussion research: determining the accumulated burden of head impacts over a lifetime. From sensor-equipped mouthguards that measure impacts in real time to advanced MRI, brain spectroscopy, and research involving former NFL players, Dr. Maroon explains how scientists are moving beyond simply counting concussions toward understanding the actual dose of impact the brain has received.The question of “How many concussions have you had?” may eventually prove to be far too simplistic.A player may experience hundreds or thousands of head impacts during years of football, hockey, rugby, MMA, military service, or other high-risk activities without every impact producing a diagnosed concussion.Dr. Maroon believes concussion research needs something analogous to the “pack-years” physicians use to quantify lifetime cigarette exposure: a way to measure the cumulative dose of repetitive head impacts to the brain.In this episode, he explains how researchers are getting closer.One of the most fascinating developments is the use of instrumented mouthguards containing accelerometers. Unlike helmet sensors, the mouthguard is coupled more closely to the skull and can measure the location, magnitude, linear acceleration, and rotational acceleration associated with a head impact.In rugby, these technologies have already been used to monitor enormous numbers of impacts. Some systems can even produce a visible alert following a sufficiently large impact—essentially creating a neurological version of the “check engine” light.An alert doesn't diagnose a concussion. Instead, it tells the medical team: this athlete experienced a significant impact and should be evaluated.But Dr. Maroon is interested in going even further.Rather than simply measuring the G-force of individual hits, researchers are investigating whether they can calculate the energy transferred during repeated head impacts and accumulate that exposure over time.Could an athlete eventually have a lifetime “dosimeter” for head impacts—similar to the radiation badges worn by people who work around X-rays?And could that information help answer one of the hardest questions in sports medicine:When has a brain had too much?Dr. Maroon also shares the story behind the development of ImPACT testing. Decades ago, while working with the Pittsburgh Steelers, head coach Chuck Noll challenged him to provide objective evidence for why a concussed quarterback should remain out for a specific period of time.That challenge helped lead Dr. Maroon and neuropsychologist Dr. Mark Lovell to develop baseline neurocognitive testing, allowing clinicians to measure processing speed, memory, and other cognitive functions before injury and compare them with performance after concussion.Today, Dr. Maroon sees impact dosimetry as another potential step forward: moving from measuring how the brain performs after an injury toward quantifying what the brain has actually been exposed to.The conversation extends beyond professional sports. Dr. Maroon discusses research involving Navy Special Warfare Combatant-Craft Crewmen, who can experience thousands of repetitive impacts from high-speed boats slamming against waves, as well as ongoing research involving former NFL and NHL players and other individuals with histories of repetitive head impacts.He also describes research combining instrumented mouthguards with diffusion tensor imaging (DTI) to investigate whether accumulated impact exposure across a football season corresponds with measurable changes in the brain's white-matter pathways.Later in the episode, the conversation turns toward what may happen biologically after years of repetitive brain stress—including oxidative stress, mitochondrial dysfunction, neuroinflammation, glutathione depletion, and neurodegeneration.Dr. Maroon explains his current research using magnetic resonance spectroscopy to measure chemicals such as glutathione directly in the brain and discusses why his team is studying strategies intended to support the brain's antioxidant defenses.You'll also hear about:Multiple concussions and cumulative head-impact exposurePittsburgh Steelers and NFL concussion historyThe origins of ImPACT concussion testingInstrumented mouthguards and real-time head-impact monitoringWhy G-force alone may not tell the whole storyLinear versus rotational forces on the...
