Concussions can happen to athletes of any age participating in all kinds of sports. From hard hits in hockey and football to accidents in gymnastics and soccer, concussions are an…
Greater Toronto Area’s Leading Multidisciplinary Clinics for Concussion Recovery
Concussions are a common form of traumatic brain injury, often caused by blows to the head. They can result in an array of physical, cognitive, and emotional symptoms that may…
Why You Should Never Skip the Neck in Concussion Evaluation & Rehab.
Every patient with a concussion is a patient with a neck injury. Let me explain. A concussion results when the brain undergoes such rapid acceleration-deceleration that shearing and stretching of…
Rethinking Concussion Recovery: The Case for Active Rehabilitation Concussions are more than just a bump on the head, or “getting your bell rung”; they are a type of mild traumatic…
In episode 17, we discussed how and when symptoms of concussion present, addressing some of the challenges in connecting with athletes and injury tracking, and some new research on CTE – also known as chronic traumatic encephalopathy.

Concussion Symptoms: How, When and Why?
Concussion symptoms can take some time to manifest after injury. The initial impact creates an electrical storm inside the brain. That electrical storm – neuronal discharge and firing inside the brain or the ‘excitation phase’ – can cause symptoms to be immediately apparent.
This massive discharge of brain cells generally calms down in a very short period of time. A patient may even feel better after a few minutes to hours after injury. This is known as ‘spreading depression.’
The initial brain cell discharge creates an imbalance within the cells of the brain, leading to an energy deficit as the cells use up all of their energy stores to reset the normal balance. These stores continue to decline for up to 7 days, potentially causing symptoms such as extreme fatigue, irritability and more emotional. This is because energy levels are depleting.
Dr. Marshall explains these concepts in detail in this episode. For more information, check out our concussion education resources.
Connecting with Athletes and Injury Tracking
Concussion management requires a team approach. Everyone involved has a role to play, particularly in sport. This remains a challenge for many sports organizations as well as their healthcare providers.
How to educate players, parents, coaches and trainers?
How to connect with athletes on and off the field?
How to provide communication to coaching staff?
How to communicate return to play status?
How to determine level of recovery?
Good concussion management needs communication to report the injury to the right person as soon as possible after injury. Proper recognition and reporting is often the first step to appropriate care.
As of this post, there is no causal link between concussions (or head trauma) and chronic traumatic encephalopathy (or CTE). There is also no evidence that the pathological findings of CTE lead to any type of cognitive impairment.
Of note, researchers have found CTE in people with no concussion history and no history of contact sports.
There’s a lot we still do not know about CTE. Listen or watch the full episode below for Dr. Marshall’s analysis of the current research around CTE.
Complete Concussions specializes in collaborative, evidence-based concussion care. Our evidence-based training programs and integrated healthcare technologies empower multidisciplinary teams to implement standardized care for those impacted by concussions.
Our network and patient database enables large-scale research to advance concussion management, and ultimately, the long-term health and well-being of concussion patients and also teach them some concussion care at home.
We analyze leading research to develop best-in-class approaches to concussion care.
