That's a bad news! There must be something similar to it in English. It's a text of a student in psychology. In Portuguese it's: Portador de Transtorno Mentais. I try to be the as "faithful' as possible to the original term. Portador = carrier Transtorno = Trouble or Perturbation and Mentais = Mental.
