pdd-nos 

Pdd-nos means 'pervasive developmental disorder (pdd) not otherwise specefied' and is an diagnose for people who are in the autistic spectrum, but who don't have the right symtomps to have an other label, like Asperger's. It is often milder than other types of autism, but can be pretty hard to live with too.

"I just got back from the psychiatrist. He said my son has pdd-nos, which is an type of autism."

PDD-NOS 

Pervasive Developmemt Disorder - Not Otherwise Specified.

A diagnosis a Doctor would give to someone who is clearly on the Autism Spectrum but has no fucking clue where you actually fall on the spectrum.
