Dr. Jon Lieff has spent decades exploring the mind and how it functions in both humans and nature. The Boston neuropsychiatrist has experience dealing with patients of several types of brain injury, including the ones that occur regularly on football fields, and across all sports.

Also a sports fan, Dr. Lieff spoke with AOL Sports to give an in-depth breakdown of brain injuries in athletes, and what can be done to make sports a safer endeavor for both adults and minors.
