The authors describe the symptoms of PDD, what a diagnosis means, how a child fits into the diagnostic terminology and the diagnostic procedures involved. They also review associated disorders such as OCD, and discuss the different treatments and therapies available.<br><br>The book includes frequently-asked questions, as well as the experiences of other parents. It is accessible, informative and supportive, a practical introduction to PDD.</p>
