A bump on the head is not serious unless the person loses consciousness…right?
Although losing consciousness is a common symptom of a concussion, it’s very possible to suffer a concussion without losing consciousness. A concussion occurs when there is a physical blow to the body or head causing an injury to your brain. The brain floats within the skull surrounded by fluid, which cushions it and prevents it from bumping into our hard skulls with every movement of the head. But the fluid may not be able to absorb the force of a sudden blow or a quick stop. In these situations the brain may slide forcefully against the inner wall of the skull. More serious injuries to the brain include bruising and swelling of the brain (contusion), a broken skull bone (skull fracture), and blood that collects in or around the brain (hematoma). Every concussion should be taken seriously. Although not usually life-threatening, concussions can have serious effects. Most people with mild injuries recover fully, but the healing process takes time.
