![]() Post-concussion syndrome can have significant negative consequences on the overall quality of life. Moreover, this syndrome may be worse in individuals who had sustained previous concussions or brain injuries. This syndrome is a set of symptoms which may continue for weeks, months, or even a year or more after having a concussion.Īccording to medical research, the risk factors for developing post-concussion syndrome include age, with increasing age causing an increased risk of developing the post-concussion syndrome, and sex, with females being more likely to develop it than males. However, up to 40% of individuals who had suffered a concussion can develop post-concussion syndrome. Typically, the brain recovers from a concussion within several weeks of the injury. What are the long-term effects of a concussion? The following are the most common short-term effects of concussions: The blood flow to the injured area is often interrupted due to bruising and inflammation, making it more difficult for the cells to receive the oxygen and nutrients needed to recover. In addition, after a brain injury, there are often harmful molecules called free radicals released in the brain, which can slow down the healing process. Often, a brain injury is followed by increased inflammation, interrupted transport of important molecules within brain cells, and disturbances in the balance of key ions necessary for nerve cell function. In some people, loss of memory (amnesia) can happen, sometimes after losing consciousness. After sustaining a concussion, it is common to experience a headache and confusion. The symptoms of a concussion can appear anywhere from several minutes to several hours following the concussion or even a few days after the injury. What are the short-term effects of a concussion? Approximately 30,000 concussions or related traumatic brain injuries are reported annually among the 12-to-19-year-old age group, 60% of which are related to sports activities.ĭespite concussions being common, many Canadians are not aware of concussion symptoms and do not know what to do when someone sustains a concussion. How common are concussions?Ĭoncussions are a common sports injury, with up to one in five Canadians have suffered a concussion when participating in athletic activities. This causes physical injury, such as stretching and breaking of the neurons (brain cells), as well as physical and chemical changes in the brain which could affect its function.Īlthough a concussion is called a mild traumatic brain injury, even a mild concussion could have serious health consequences. Moreover, different parts of the brain move inside the skull at different speeds, creating shearing forces which could stretch and tear brain tissues. ![]() The brain can become bruised from being pushed against the skull. How do concussions affect the brain?ĭuring the traumatic blow to the head which causes a concussion, the brain rapidly moves back and forth, bouncing and sometimes twisting inside the skull. It is important to be aware of the short- and long-term consequences of concussions, as they can be severe. According to a recent online survey commissioned by the Public Health Agency of Canada, approximately half of Canadians know almost nothing about the dangers of concussion injuries.Ĭoncussions and other brain injuries resulting from trauma are often seen in some sports and physical activities, and their effects can range from mild to severe. ![]() Concussions are a type of mild traumatic brain injury and often result from having a bump, blow or jolt to the head. ![]()
