types of therapy?

Hi. I have recently been diagnosed with RAD. I've know all my life that I was a loner and didn't have the attachement feelings it looked like others did. So, now I know what it is, but is there any proven therapy for it? I've read about treating children with RAD. Does anyone know what helps with adults?

A year too late with a reply but I'm exploring EMDR as a potential therapy. I'm reading this a book by Francine Shapiro. Look her up in your favourite search engine.
