We reviewed the stability of the diagnosis of pervasive developmental disorder not otherwise specified (PDD-NOS). A Medline search found eight studies reiterating a diagnostic assessment for PDD-NOS. The pooled group included 322 autistic disorder (AD) and 122 PDD-NOS cases. We used percentage of individuals with same diagnose at Times 1 and 2 as response(More)
BACKGROUND The existence of bipolar disorder type I (BD-I) during adolescence is now clearly established whereas there are still some controversies on BD-II and BD-NOS diagnosis, mainly in Europe (O'Dowd in Br Med J 29, 2006). Little is known on the phenomenology and potential short-term prognosis factors of bipolar episodes in this age population. In(More)
