An individual experiences a traumatic brain injury when a form of external force causes harm or injury to your brain. External forces such as this can create neurological trauma when it comes from a violent blow to a head or body. Not only can external forces cause harm, but anything that may potentially pierce or penetrate the skull can cause traumatic injury.
Traumatic brain injury can have wide-ranging effects both physical and psychological. Some signs or symptoms of the injury may appear immediately after the traumatic event, while other symptoms may not appear until many days or weeks later.
Mild traumatic brain injury
Not all traumatic brain injuries are severe. In fact, there are brain injuries that exist which are mild in nature and simply cause temporary dysfunction of brain cells. With mild traumatic brain injury it is not expected that a person would suffer from permanent damage.
Some of the typical signs and symptoms of mild traumatic brain injury may include:
Being dazed, confused or disoriented
Fatigue or drowsiness
Loss of consciousness
Memory, mood or concentration problems
Nausea or vomiting
Sensitivity to light or sound
Sleeping more than usual
Moderate to severe traumatic brain injuries
More serious traumatic brain injury can result in bruising, torn tissues, bleeding and other physical damage to the brain that can result in long-term complications or death.
Moderate to severe traumatic brain injuries can include any of the signs and symptoms of mild injury, as well as the following symptoms:
Clear fluids draining from the nose or ears
Coma or loss of consciousness for extended period of time
