Pervasive developmental disorders, PDD’s, are a group of recognized syndromes which are evident in childhood. PDD’s include Asperger’s syndrome, autism, Rhett’s disorder and others. These disorders are difficult to diagnose but the effects are seen in young children who have difficulty with social situations, communication and often develop repetitive behaviors around specific interests or triggers. The symptoms will often be noted by parents, teachers or other caregivers. Diagnosis usually involves specific psychological testing. A child with PDD will need accommodations at school and extra social support. Therapy is helpful in teaching the child specific skills, helping the family understand how to respond to symptoms, and learning to advocate for needed understanding and support.

What is Autism Spectrum Disorder
From Autism Speaks:
Autism, or autism spectrum disorder, refers to a range of conditions characterized by challenges with social skills, repetitive behaviors, speech and nonverbal communication, as well as by unique strengths and differences. We now know that there is not one autism but many types, caused by different combinations of genetic and environmental influences.
The term “spectrum” reflects the wide variation in challenges and strengths possessed by each person with autism.
Autism’s most-obvious signs tend to appear between 2 and 3 years of age. In some cases, it can be diagnosed as early as 18 months. Some developmental delays associated with autism can be identified and addressed even earlier. Autism Speaks urges parents with concerns to seek evaluation without delay, as early intervention can improve outcomes.
