Which diagnostic criteria are used to assess a traumatic brain injury?

The assessment of a traumatic brain injury (TBI) primarily relies on a thorough history and physical examination. This approach allows healthcare professionals to gather crucial information about the patient's symptoms, the circumstances surrounding the injury, and any previous medical history that may be relevant.

During the physical examination, healthcare providers evaluate the patient's neurological status, including consciousness level using scales like the Glasgow Coma Scale, pupil reactions, motor responses, and other neurological functions. These assessments are vital for determining the severity of the injury and guiding further diagnostic testing or treatment.

Other options, such as blood test results, electrocardiogram results, and skin condition assessments, do not provide direct information regarding the brain's condition or function after a trauma. While these tests may have their places in comprehensive patient evaluation, they are not central to diagnosing or assessing the effects of a traumatic brain injury. Thus, the history and physical examination remain the cornerstone of TBI assessment.
