Brain injury is mostly caused by a violent episode or accidents that hits harshly and directly on the head. It can also occur due to an object that goes through the brain tissue, such as a bullet or broken piece of skull. Mild traumatic brain injury can affect your brain cells temporarily. Serious traumatic brain injuries can result in bruising, torn tissues, bleeding and other physical damage to the brain. These brain injuries can even lead to serious long term complications and can be fatal too.

Brain injury diagnosis and treatment
Brain injuries are mostly emergencies and require immediate medical or surgical treatment. In the case of more serious traumatic brain injury, the consequences can worsen rapidly if left untreated and ignored. Doctors have to make a complete diagnosis as soon as possible. There is a Glasgow coma scale, which is a 15-point test that helps your health care professional in determining the severity of the brain injury by checking a person's ability to listen to various instructions including directions and moving eyes and other parts. Speech abnormalities can also help in doing a proper brain injury diagnosis by the doctor.
Brain injuries mostly do not require any course of treatment other than rest and pain relievers for headaches. But, a person with mild traumatic brain injury usually has to be observed or monitored closely at home for any persistent, worsening or new symptoms, be it physical or psychological. Emergency care for moderate to severe traumatic brain injuries aims on providing enough oxygen and the correct blood supply, maintaing optimum blood pressure and preventing any future injuries on neck or head to all the people. Emergency surgeries might be required for less additional damage to brain tissues. Some medicines can help in relieving pain and numbing the injured area.
