Any injury to the head is absolutely a big deal.
The medical terms for ‘mild’, ‘moderate’, and ‘severe’ brain injury are used to describe the scale of the effect the injury had on your brain function. Even a mild brain injury can still be a profoundly serious injury with potentially long-lasting consequences if it is not promptly diagnosed and treated. If you have experienced a blow or other traumatic injury to your head, please seek medical attention as soon as possible.
