The review below comes from Ms. Beka Martinez of the Autism Society of Virginia, mother of a son with autism, and leader in the autism community: 

"I have read many books on Autism; I believe that Autism Spectrum Disorders from A to Z  is a definitive volume that should be the first book recommended to parents, family members, and professionals seeking information.  I always try to take myself back to "before I knew anything" to try to follow the progression of information in books and articles and invariably I am lost by the time I hit chapter 3; not so this time.  The information in Autism Spectrum Disorder, from A to Z and the Spanish version, Los Trastornos del Espectro de Autismo De la A a la Z flows easily and naturally. The authors did a phenomenal job using clearly understandable and non-emotional terms.  I wish this book had been in print when my son was diagnosed so many years ago."
