Pervasive Developmental Disorder (PDD) is a subset of Neurodevelopmental Disorders (ND). PDD (or Autism Spectrum Disorders (ASD)) is not the same as a Neurodevelopmental Disorder (ND) which also includes genetic-based disorders (such as Down Syndrome or Williams Syndrome), learning/cognitive disorders (such as Learning Disorders (LD) or Attention Deficit Hyperactivity Disorder (ADHD)), as well as environmentally induced disorders (such as Fetal Alcohol Syndrome (FAS) or Lead Poisoning). Please do <not> lump ND as a kind of PDD. ND is the superorderinate category underwhich PDD is typically placed.
Thanks.
