Concussion is the most common form of brain injury.   A concussion may occur when the head hits an object, or a moving object strikes the head.  A concussion is a minor or less severe type of brain injury, which may also be also called a traumatic brain injury.  Effects are usually temporary but can include headaches and problems with concentration, memory, balance and coordination. Concussions are common, particularly if you play a contact sport, such as football. But every concussion injures your brain to some extent.  This injury needs time and rest to heal properly. Most concussive traumatic brain injuries are mild, and people usually recover fully.  Prevention is still the best way to keep us healthy.  Still, many things can happen with contact sports and one of the most common is having a concussion. When the head is forcefully hit against the skull, the brain is disturbed. It swells and at times, one can faint depending on the severity of the blow to the head.

Your health care providers will explain what to expect, how to manage any headaches, how to treat your other symptoms, when to return to sports, school, work, and other activities, and signs or symptoms to worry about.
