Concussions are mild traumatic brain injuries caused by bumps, jolts, or blows to the head. In this type of injury, the brain bounces around or twists in the skull due to the sudden movement. As a result, brain cells are stretched and damaged and chemical changes are brought about in the brain. Concussions can also result from a sudden jolt to the body if the impact causes the head to be forcefully jerked backwards, forwards, or to the side.
Usually a concussion isn’t life-threatening, so it’s classified as mild. A concussion, however, can cause serious effects that can last for days, weeks, or even months.
The post-concussion syndrome, or PCS, is marked by headaches and dizziness, which may last for weeks, months, or even a year following a concussion. Usually, concussions are caused by a blow to the head. However, they can also be caused by violent shaking and movement of the head or body. To get a concussion or post-concussion syndrome, you don’t have to lose consciousness. The severity of the initial injury doesn’t seem to affect the risk of post-concussion syndrome.
Symptoms usually occur within the first seven to 10 days and resolve within three months. The symptoms may persist for as long as a year.
It is possible to treat symptoms with medication, physiotherapy, and behavioral therapy, and provide individuals with the expectation that recovery can occur.
