A concussion is a functional brain injury resulting from a direct blow to the head or the result of the brain being exposed to abnormal forces (without a direct blow to the head) as in a whiplash event occurring in sporting events or motor vehicle accidents.
Signs and symptoms of a concussion may include pain, dizziness, nausea, irritability and concentration issues. Statistically, the majority of functional brain injuries from concussions do not show any findings with special imaging such as a CT (CAT – Computerized Axial Tomography) scan, however, some do. When a concussion is severe enough, structural changes can occur which can be detected with a CT scan.
Severe and unresolving headaches, nausea, vomiting, seizures, arm weakness, slurred speech, confusion and drowsiness are indications for advanced imaging evaluation such as a CT scan. CT scans can show structural injuries such as brain bleeding, skull fracture and/or brain tissue damage.
When there is evidence of a concussion, CT scans are routinely ordered by emergency room physicians and private practice physicians to evaluate the extent of the brain injury. If you have had a concussion, consult your physician.
