Diagnosing RAD

I hope this is not too techno boring. The reason I am writing this is post is because of my confusion about diagnosis while reading books on RAD. Many of them talk about the DSM-IV. The tool used in diagnosing RAD is the DSM-IV. It is written for professionals. This is the Diagnostic and Statistic Manual of Mental Disorders with the IV being for the 4th revision. They are currently working on V. The books I read listed subtypes of RAD but depending on the year the book was printed the subtypes were different. The revisions of the DSM were the reason for this. They may change with the release of DSM-V. Who knows what the subtypes will be then...? You find a lot of different definitions and subtypes listed on the Internet. Confusing. There are currently only 2 subtypes Inhibited and Disinhibited. I personally thought the last definition they used was much easier to understand but for some reason they didn't ask me about revising it : )

Disinhibited:

not having a discriminated, preferred attachment figure,
not checking back after venturing away from the caregiver,
lack of reticence with unfamiliar adults,
a willingness to go off with relative strangers

Inhibited:

absence of a discriminated, preferred adult,
lack of comfort seeking for distress,
failure to respond to comfort when offered,
lack of social and emotional reciprocity, and
emotion regulation difficulties.

There are many sites with this info but I took this from http://en.wikipedia.org/wiki/Disinhibited_attachment_disorder

I will say I find this all as clear as mud. It would be great if parents were kept in mind when writing these definitions. Personally, I say if your child has many of the symptoms listed to the right they should be evaluated by a professional and leave the diagnosing to them. The subtypes don't matter so much as the treatment. We are currently seeing a psychiatrist, attachment therapist, EMDR therapist and an Occupational Therapist. Do what you have to do for your child to heal.
