What is a concussion?

A concussion is a type of mild traumatic brain injury (mTBI) that happens when there is a bump, blow, or jolt to the head or when there is a hit to the body that causes the head and brain to move rapidly back and forth. Concussions disrupt normal brain function and can lead to temporary problems with how you feel, think and act. Even though a concussion is classified as a “mild” TBI, it needs to be taken seriously, as poor care can lead to longer lasting symptoms, permanent functional loss, and in rare cases, death. 

Signs and symptoms

As the brain attempts to heal itself from the concussion, the brain needs more resources and energy than the body can provide. This “energy crisis” leads to multiple signs and symptoms associated with concussion.

There are four categories of symptoms that can be experienced with a concussion. They include physical symptoms, cognitive symptoms, emotional symptoms and sleep/energy symptoms.
