What is a concussion?
A concussion is a type of mild head injury. It is caused by a direct hit or blow to the head, neck, or body, resulting in some movement of the brain within the skull. This causes a temporary change in how the brain functions. These changes occur at a cellular level, which means structural damage cannot be seen on a clinical brain scan.
Concussion is a common injury. There are many causes of concussions including falls, recreational injuries, car accidents, or sports.
While many children and adults with concussion will notice their symptoms improve within a few days, it can take up to four weeks to recover from a concussion.
Approximately 30% of children and adults may experience symptoms for longer than 4 weeks. Early identification of concussion and appropriate management in the early stages post-injury can help to accelerate recovery. It is therefore important a suspected concussion is not ignored.
