There are numerous similarities between a concussion and a traumatic brain injury. Nevertheless, there are important differences you should be aware of.
The biggest distinction is the level of trauma and damage suffered by an individual. For example, when someone suffered a traumatic brain injury, they may have lost consciousness for 30 minutes or longer.
In addition, TBI victims often encounter bouts of amnesia. In contrast, when someone suffers a concussion, the victim may not experience significant trauma to their brain. In many instances, a victim who suffered a concussion may not lose consciousness and could enjoy a fairly speedy recovery.
A good way to think about the difference between a concussion and a traumatic brain injury is that a concussion is the equivalent of a fender-bender. A traumatic brain injury is equivalent to your vehicle being totaled.
