You don’t have to receive a blow to the head to suffer from brain injury. In fact, you can even injure your brain while wearing a helmet. This is because brain tissue is very delicate — the consistency of soft butter or egg white — and floats inside a skull lined with hard ridges. Impacts to the body, falls, and neck injuries are all it takes to injure the brain, especially if they happen repeatedly.
Here are some ways you can sustain a brain injury without ever hitting your head:
Hard falls: When you fall your brain slams into one side of your skull and then the other. People who engage in activities that involve falling and crashing regularly (football, extreme sports, roller derby, etc.) should be aware of signs of brain injury, even if they wear a helmet.
