Mild brain trauma

A temporary injury to the brain caused by a bump, blow or jolt to the head that usually lasts a few days or weeks

What is concussion?

Concussion is a mild traumatic brain injury which occurs after sustaining an injury to the head through an accident or an object forcefully coming into contact with the head. It may or may not be accompanied by a loss of consciousness. The concussion may disrupt the brain’s ability to process sensory information.

Concussion in sport

Concussion describes a head injury sufficient to disturb brain function on a temporary basis with no structural changes detected on the scan and is the most common form of head injury, both in sport and every day life.


One concussion tends to lead to another if a competitor returns to play too soon. Symptoms become progressively worse on each occasion, which can not only impact on the current season, but also cause more long term implications. Retired American Football players have been particularly studied for the effects of concussion. The players are shown to suffer high levels of depression, Parkinsonism, suicide and early death.  


In 2017 The International Conference on Concussion in Sport convened to bring consensus to the study, diagnosis and management of concussion. FIFA, the International Olympic Committee, and the International Rugby Board are included in the list of supporting organisations. 


At HCA UK we work in partnership with the Institute of Sport and Exercise Health, who run concussion clinics for amateur and professional sportsmen and women.

    The majority of concussions resolve in around a week with rest. We advise that you avoid mentally taxing activities while you recover.
