an example of what I mean is found here
http://www.dsm5.org/Documents/PTSD%20Fact%20Sheet.pdf

instead of finding a DDNOS on the DSM 5 website Home | APA DSM-5

when you check out PTSD you see it now has a dissociative disorder subtype...

PTSD Preschool Subtype and PTSD Dissociative Subtype
DSM-5 will include the addition of two subtypes: PTSD in children younger than 6 years and PTSD with
prominent dissociative symptoms (either experiences of feeling detached from one’s own mind or
body, or experiences in which the world seems unreal, dreamlike or distorted).


basically the DDNOS symptoms have been included with the PTSD diagnostics now and is now called PTSD Dissociative Sub Type.

you can read more about the changes in the DSM 5 at their website

Home | APA DSM-5


I just clicked around on the DSM 5 website and found a link that leads to the index of the DSM 5 DSM-5 | psychiatry.org and click on table of contents...

DDNOS is .....not..... one of the labels in the index under dissociative dissociative disorders....the dissociative disorders are as follows

Dissociative Identity Disorder
Dissociative Amnesia
Depersonalization/Derealization Disorder
Other Specified Dissociative Disorder
Unspecified Dissociative Disorder

After placing a phone call I was able to find out that

other specified Dissociative Disorder is ......probably.....what americans call Conversion disorder

and UDD is ......probably ..... be what some of the DDNOS symptoms are now called..

again I do ........not........ have a copy of the DSM 5 so I am unable to tell you for sure what OSDD and UDD is. We are just making a guess here.
