Traumatic brain injury (TBI) can be mild, moderate, or severe. Concussions are usually classified as mild TBI. Direct hits to the head, such as falls or sporting accidents can lead to patients developing concussions. Unlike other brain injuries, no blood is found within the skull. Nevertheless, these are still serious injuries that require monitoring for hours or days after the accident. Most concussions do not involve a loss of consciousness and are managed non-operatively. Patients often experience headaches, ringing in the ears, nausea, vomiting, and blurry vision after a concussion. Untreated concussions have been linked to long term brain injury. Recovery from a concussion involves adequate rest. Patients rest and then should gradually perform activities of daily living in a step-wise fashion, as and when tolerated. If you have experienced any form of neurotrauma, consult a physician.
