I think this talk is relevant. It's not specifically about convicts but includes them. "The most important lesson from 83,000 brain scans | Daniel Amen | TEDxOrangeCoast" https://www.youtube.com/watch?v=esPRsT-lmw8 https://www.youtube.com/watch?v=esPRsT-lmw8 My summary of the thesis of the talk: Brain injury is far more common than is generally realised, contributes to many kinds of behavioural issues far more than is realised, is visible on scans, and is to some extent treatable, but it's usually not considered or examined.
