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

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 Concussion

One 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 Care

Despite 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 Education

For 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 important perspective on what we know, what remains uncertain, and where concussion research is headed.
