A 2012 lawsuit against the Bureau of Prisons alleged that years of isolation and almost no human contact had serious eroded the social skills and ability to adapt of of ADX inmates.
According to the lawsuit, many prisoners at ADX facilities "interminably wail, scream and bang on the walls of their cells."
"Some mutilate their bodies with razors, shards of glass, sharpened chicken bones, writing utensils, and whatever other objects they can obtain. A number swallow razor blades, nail clippers, parts of radios and televisions, broken glass, and other dangerous objects," the suit said.
