Why does brain trauma develop?
Traumatic brain injury usually results from a violent blow or jolt to the head or body. An object that penetrates brain tissue, such as a bullet or shattered piece of skull, also can cause traumatic brain injury. Brain damage can be caused by falls, accidents, sports injuries, and more.
Mild traumatic brain injury may affect your brain cells temporarily.
More-serious traumatic brain injury can result in bruising, torn tissues, bleeding and other physical damage to the brain. These injuries can result in long-term complications or death.
Symptoms:
Traumatic brain injury can have wide-ranging physical and psychological effects.
Some signs or symptoms may appear immediately after the traumatic event, while others may appear days or weeks later.

When to see a doctor
Always see your doctor if you or your child has received a blow to the head or body that concerns you or causes behavioral changes.
Seek emergency medical care if there are any signs or symptoms of traumatic brain injury following a recent blow or other traumatic injury to the head.
The terms "mild," "moderate" and "severe" are used to describe the effect of the injury on brain function. A mild injury to the brain is still a serious injury that requires prompt attention and an accurate diagnosis.
