A concussion is caused by any forceful bump, blow or jolt to the head or body that results in rapid movement of the head. It is a serious injury that can cause a range of short- or long-term changes. These changes can affect:
- Memory and reasoning
- Touch, taste and smell
- Communication, expression and understanding
- Mental health, causing depression, anxiety, personality changes, aggression, acting out, social inappropriateness
More than one mild concussion over months or years can result in cumulative changes in thinking, sensation, language or emotions. Research shows concussions can later cause epilepsy and increase the risk for conditions such as Alzheimer’s disease, Parkinson’s disease and other brain disorders. More than one mild concussion within hours, days or weeks can be catastrophic and even fatal.
