DES-NOS is a new diagnosis proposed to be added to the DSM V to be published in 2011. It stands for Disorders of Extreme Stress - Not Otherwise Specified. It is proposed to be the official DSM V coding for what may otherwise be known as "complex PTSD" or c-PTSD.

I deeply hope though that when they finish the DSM V and code for DESNOS, they will be very specific in their diagnostic criteria in differentiating DESNOS/cPTSD from BPD...
