Have you ever had a concussion? Even if you haven’t, chances are you've heard the term CTE. But what do we really know about Chronic Traumatic Encephalopathy? Is this something you should worry about if you've had a concussion?
CTE is a brain disease that can only be diagnosed after death (i.e., postmortem). There is currently no drug test that can tell if you have signs of CTE. It has been hypothesized that a Positron Emission Tomography (PET) Scan can be used to diagnose CTE, but the specificity of this test is not high enough to determine with certainty whether someone has the brain disorder or not.
In a postmortem dissection, CTE can be diagnosed based upon an accumulation of Tau proteins, specifically around the areas where cerebrospinal fluid had flowed throughout the brain. You may have heard of Tau protein before. The tangles of these proteins are similarly found in patients with Alzheimer’s disease. In fact, many of what are described as symptoms of CTE are also symptoms of Alzheimers. These can include memory issues, moodiness/mood changes, headaches and anxiety.
Most importantly, there is no link between increased episodes of concussion and the presence of CTE. Despite a New York Times article stating that 110 out of 111 NFL football players had CTE, the diagnostic criteria for CTE remains unclear. This article did not mention the amount of Tau present in each brain. There might have been the presence of only a few tangles in the dissection that resulted in a diagnosis of CTE.
Moreover, the 2017 research study referenced in this article failed to mention if there were any clinical signs or symptoms that were similar among the people (premortem) whose brains were later studied. Additionally, all of the brains in the study were donated, which could have inherently biased the population. This study was also performed by a CTE research group, and was not independently researched.
Ultimately, while we know that contact sports do increase our risk of head injuries and concussions, more research has to be done before we can say that football, soccer, or any sport increases our likelihood for developing CTE. We shouldn’t necessarily avoid an activity or exercise just because we sustained a concussion. More importantly, we should learn and practice safe training techniques to reduce our risk of injury.
As a physical therapist, I can provide valuable education, specific exercises and training techniques to help prevent these injuries. For those who do sustain a concussion, rehabilitation can be key to helping the brain recover. Click here to find an Activcore location near you.

ABOUT THE AUTHOR:
Nick Passe is a Doctor of Physical Therapy (DPT) who specializes in contact sports like football, basketball, lacrosse and ice hockey. He works at Activcore in Princeton, New Jersey, located just 2 miles from Princeton University.
As a former football player and college cheerleader, Nick knows what it takes to succeed in competitive sports and to overcome injuries. He holds a Bachelors degree in Psychology and Natural Sciences from Pittsburgh University, as well as a Doctorate degree in Physical Therapy from the University of Medicine and Dentistry of New Jersey (now part of Rutgers University), ranked among the top 50 PT schools in the country. He also has advanced post-graduate training in movement assessment and treatment of athletes, including concussion management and prevention.
Nick goes beyond the symptoms and looks at the whole body to help his athletes recover from pain and injury, and safely return to a fulfilling life of sport, activity and wellness. He is among just a handful of physical therapists nationwide to have earned the prestigious designation as a Certified Neurac Provider (CNP), making him exceptionally equipped to evaluate and treat each athlete from head to toe.
Applying the principles of Neurac (Neuromuscular Activation), Nick utilizes the Redcord suspension system to optimize how the mind and muscles work together as one. This is an evidence-based method that a few high-level sports teams are using to keep their athletes healthy and free from pain and injury. In fact, Nick has the pleasure every few months to teach these principles to both the Washington Capitals NHL team and the Washington Nationals MLB team. [READ MORE]
