What is the definition of Mild TBI?

Mild traumatic brain injury (TBI) is often synonymous with a concussion, which is characterized by a temporary disruption in brain function due to an external force, typically from a blow to the head or body. This definition encompasses the various symptoms associated with mild TBI, including confusion, headache, and dizziness, which may arise immediately after the injury. Although symptoms can resolve quickly, the term "mild" does not imply that the injury is insignificant, as it can still result in lasting cognitive and physical effects.

The other choices do not accurately describe mild TBI. Severe brain injuries typically involve more significant damage and often lead to prolonged unconsciousness or serious long-term impairment. Physical trauma in a general context does not specifically refer to brain injuries, and spinal cord injuries are distinct from TBIs, involving damage to the spinal cord rather than the brain itself. Therefore, recognizing a concussion as a type of mild TBI aptly captures the essence of the condition.
