As the parent of a child recently diagnosed with Noverbal Learning Disorder (NLD), I was looking for information on what was NLD and what it meant for the future of our child. The clinicians at Yale Child Study Center suggested this volume as a good starting point. It just be that it matches my style of communication, but I found this book to be incredibly clear, well organized, well written, and to the point. There is no fat on this book, just what you need.
There are three major sections on (1) an overview of NLD/Aspergers; (2) how these disorders effect the executive, sensory, and social parts of the kids lives; (3) and what educational and home programs are required to help people with NLD/Aspergers. There are assessment criteria, diagnostic criteria, and pointers to other resources. The curriculum that Ms. Stewart lays out is the one that she uses at the private high school for Aspergers/NLD kids (Orion Academy in Moraga, CA). The tasks she lays out are not going to be easy for anyone to accomplish, but they are worth doing.
I can't think of a better place to start in trying to understand what the child with NLD/Aspergers feels, is facing, and has to do to seek some accommodation with us NT's (neurotypicals).
BTW, the other book recommended by the Yale group for understanding NLD is RV Whitney's "Bridging the Gap: Raising a Child with Nonverbal Learning Disorder".
