Child or adult,its hard to deal with anyone who has a mental disorder. Even the slightest disorder can make dealing with that person tough. When I deal with those types of people,first and foremost,I try to talk to them. Depending on that persons disorder,you have to modify how you interact with them. Some persons have an adult body and the mind of a child. The key is to be able to identify that persons disorder and act accordingly. If it has escalated to violence,then I respond accordingly too. Hopefully,that subject can be restrained with minimal use of force,or less lethal means.
I keep in mind that they can't help it and try not to hurt them if I don't have too. But,I do not let my guard down just cause they are handicapped. I just try to deal with them a little different.
Lead me not into temptation.......someone talks me into enough sh!t as it is. .
