This book is a real reference, I think, for Asperger syndrome as with PDD-NOS (those might be called, for simplification, Asperger light, because there is not sufficient criteria for a SA diagnosis but there are enough to think about what PDD). It is a pity that the author did not return on the causes / origins of Asperger's syndrome, but it is up widely in detail and above all understandable, on Asperger demonstrations in different areas "affected" by this syndrome . It offers solutions to make life easier for people with Asperger and those around them. Above all, there is no negative judgment against Aspergers. The author knows the subject to work with Aspergers and have his family by marriage. So I have full confidence in him rather than French doctors who refuse to see the TED opposite view and prefer other problems as causes of our worries.
