A mild concussion cannot be considered a minor injury, the so-called minor injury, mainly refers to personal injury disability identification and road traffic accident disability identification was identified. Concussion is the mildest kind of cranio-cerebral injury, the patient is only briefly unconscious and does not have any positive neurological signs after waking up, at most there is a little dizziness, lightheadedness, discomfort, but the neuroimaging tests such as cranial CT and cranial MRI are negative. Patients will not have any after-effects and will not cause any impact on their future life, so concussion is not able to be recognized as a minor injury. However, according to the current regulations governing work-related injuries in China, if a patient suffers a traumatic injury at work and is diagnosed with a concussion, it can be recognized as a work-related injury.
