A concussion is an injury to the brain, usually resulting from a direct blow to the head. It is believed that the force of the blow causes the bulk of the brain to rotate slightly with respect to the brain stem, causing disruption in those parts of the brain where the rotational stresses are greatest. The physical effects of the concussion itself don’t show up on CT scanning. The CT scan is used to rule out other, potentially much more dangerous, damage from the impact, including skull fracture and bleeding in or around the brain. If the CT scan is negative and the patient has a normal neurological examination, overnight observation is usually not needed. However, slight neurological changes are not uncommon with concussions, and being held overnight does not necessarily indicate a more serious injury. The effects of a concussion may resolve in a few days, or they may last for weeks or months. These long-term effects may include memory problems, difficulty concentrating, increased sens
