Pervasive developmental disorders (PDDs) include autism and a range of other neurological disorders. While at least 250,000 Americans have been diagnosed with PDD-NOS--one-third of whom are children--twice as many may remain undiagnosed or misdiagnosed. Parents of a young child with undiagnosed PDD may suspect any number of things, from autism to severe allergies.
