A head injury can be the result of a motor vehicle accident or any other impact; it has a direct impact on the individual’s ability to function. If the victim is unable to receive the most effective medical treatment, the effects can be felt not only by the patient but also by his or her friends and family.
According to the U.S. National Institutes of Health, a closed head injury results from a blow that does not penetrate the skull, while an open head injury results from a blow that breaks into the skull. A traumatic brain injury (TBI) is a type of head injury that causes a change in the brain’s function that may range from mild to severe. A concussion is a mild form of TBI.
Symptoms of mild TBI include confusion, headache, blurred vision, sleep disruption, fatigue, behavioural or mood changes, and trouble with concentration, thinking, and memory. Patients with moderate to severe TBI may experience these symptoms, as well as convulsions, vomiting, weakness or numbness in the extremities, restlessness or agitation, and loss of coordination.
