This book was written with an intelligence, wit, and clarity that is very rare for such a technical subject. Don't be fooled by the title. The book covers autism, PDD, ADHD, Sensory integration disorder, irritable bowel syndrome, and many other neurological and gastrointestinal conditions. The author teaches rather than preaches on the science, experiences, and the how-to of using long overlooked digestive enzymes to help with many related health conditions. I went away with the knowledge I needed to understand the options and make my own informed decisions. Read it before you start any biomedical or behaviorial program. And if you have already started a program, read it so you can finally understand what is really going on, and how it can be improved with enzymes.
