i believe this is a very helpful companion book for any parent or caregiver of someone who receives an autism diagnosis, along with those with an aspergers or adhd diagnosis, though the book gives more attention to those people on the autism spectrum. although there are several potentially helpful recommendations the book gives, those i find most pertinent are regarding the potential benefit of omega-3 and vitamin b6 supplementation, as well as foods high in these vitamin contents. also, i like that the book gives advice to caregivers about finding a nutritionist for consultation, as some of the steps this book suggests are rather technical.
