This incredible infographic was created by the Allen & Allen Law Firm. It is one of my favorite recent infographics, with such a nice visual style & lots of interesting information. The source is found here. The highest rate of brain injuries happens to people ages 15-24. Children under 5 and people over-ager 75 also have a higher risk. Also, after your first brain injury, you are 3 times more likely to have a second, and then 8 times more likely to have a third.
