Resources › Concussion
A concussion is an injury to the brain that can cause a temporary disruption to how the brain is functioning. They can be caused either directly (e.g. a hit to the head) or indirectly (e.g. an insult to the body that transfers force to the head). This force to the head causes the brain to move within the skull. It typically causes brain tissue to change at a cellular level, leading to a rapid onset of neurological changes.
All concussions are traumatic brain injuries and should be treated as serious events. Most individuals begin to feel better about 10-14 days after an injury, with most symptoms resolving around 3-4 weeks. However, about 15% to 30% of individuals will continue to have persistent symptoms after a concussion. Some other factors may begin to cross over with concussion symptoms or make symptoms worse. Risk factors for prolonged symptoms can include: previous concussion, history of migraines, learning disabilities or ADHD, depression or anxiety, age, sex (females tend to be higher risk), visual and vestibular abnormalities, sleep abnormalities, improper management and misinformation.
Concussion rehabilitation should involve a multidisciplinary team who looks at all areas of life. Depending on the challenges someone is experiencing, it could include sleep education, cardiovascular exercise, movement retraining, balance exercises, vestibular rehabilitation, vison therapy, manual therapy, pacing and planning, school or work modifications and counselling. When someone experiences a concussion, the symptoms themselves can be overwhelming. People can feel confused, lost and overwhelmed by emotions and dizziness. Targeted rehabilitation exercises challenge the brain in a way to expose it to a provoking item, then giving it time to learn how to process this information. Our brains are continually changing and evolving (they are neuroplastic!). Targeted rehabilitation can help the brain to re-learn how to process information from its surroundings so that the information is no longer overwhelming for the brain.
