Concussion is a mild traumatic brain injury (mTBI) which occurs when there is a high force through the brain, causing a stretch/ shear of the brain neurons. It is a functionally injury rather than structural - so if managed correctly it is believed you can make a full recovery.
Through a cascade of events the traumatic force leads to an energy crisis in the neurons. The time is takes for this energy crisis to be resolved is not fully known and varies between people, concussion history and severity of concussion, but resolution is believed to take around 20-30 days. Testing against multi-modal baseline scores is the best available measure to see when this recovery has likely taken place.
​Unfortunately, a resolution of symptoms does not indicate a recovery of this system with the brain neurons still needing more time to recover before a return to sport.
