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.
