A concussion is a traumatic brain injury that alters the way your brain functions. Effects are usually temporary but can include headaches and problems with concentration, memory, balance and coordination.
Although concussions usually are caused by a blow to the head, they can also occur when the head and upper body are violently shaken. These injuries can cause a loss of consciousness, but most concussions do not. Because of this, some people have concussions and don’t realize it.
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.
Rest is the most appropriate way to allow your brain to recover from a concussion. Your doctor will recommend that you physically and mentally rest to recover from a concussion.
This means avoiding general physical exertion, including sports or any vigorous activities, until you have no symptoms.
This rest also includes limiting activities that require thinking and mental concentration, such as playing video games, watching TV, schoolwork, reading, texting or using a computer.
Your doctor may recommend that you have shortened school day or workdays, take breaks during the day, or have reduced school workloads or work assignments as you recover from a concussion.
As your symptoms improve, you may gradually add more activities that involve thinking, such as doing more schoolwork or work assignments, or increasing your time spent at school or work.
