For years, experts thought that concussions occurred because the brain bumped up against the rough interior of the skull, causing a “bruise” on the brain. We now know that that is not the case at all; in fact, there is no bruising of the brain that occurs.
What experts now believe to be true about this brain injury is that the brain tissue acts somewhat similar to Jello; as forces from a traumatic event are transmitted to the head, the brain tissue stretches, causing damage to the small roadways or pathways that bring messages from one cell to the next, called axons.
In most cases, these changes are temporary and only last a very short time (minutes, hours, or days); however, you cannot see these changes on any type of traditional brain scans or imaging.
Thus, it is important that you seek medical care immediately to ensure you get the right care at the right time.
