A concussion is a type of brain injury caused by a bump, blow or jolt to the head that can change the way your brain normally works. Concussions can occur in any athletic activity as well as a motor vehicle crash or fall. Most concussions occur without a loss of consciousness. A healthcare provider with expertise in concussion management should evaluate all concussions. The primary risks of not receiving a medical evaluation may include:
- Increased risk for severe brain injury or even death (Second Impact Syndrome)
- Prolonged symptoms
- Difficulties with schoolwork and other activities
- Delayed return to sport
During recovery, exercising or activities that involve a lot of concentration (such as studying, working on the computer, or playing video games) may cause concussion symptoms to reappear or get worse.
