|What are Pervasive Developmental Disorders (PDDs)?
PDDs are a range of neurological conditions that adversely affect a person’s speech and communication, emotional growth, socialization, and physical capabilities. PDDs range from Asperger’s syndrome (at the less severe end) to autism. In the middle of this spectrum are the most frequently diagnosed PDDs: PDD-NOS (not otherwise specified) and Atypical PDD. Children with these diagnoses meet some, but not all, of the criteria for autism.
What causes PDDs?
Bad parenting used to be blamed, but all of the pervasive developmental disorders are rooted in a complex combination of genetics, individual brain wiring, and environmental factors. Some researchers suspect viruses, vaccines, pollution or metabolic problems in the increasing number of cases.
“It’s been three months since the diagnosis. I don’t know if my boy is going to be okay, I don’t know if I’m going to be okay, I don’t know if this marriage is going to be okay. Some days I keep wishing this was a dream. And then I wake up, and it’s so not-normal, and there’s nobody among our old friends or at work who I can talk to about it.” Peter, father of three-year-old Morgan, diagnosed with PDD-NOS
