You asked you helpful books to diagnose hyperactivity with allergies.
"Is This Your Child" by Dr. Doris Rapp was VERY helpful in diagnosing my son
milk allergy and hyperactivity connection.  Dr. Rapp also has a book out
called "Is This Your Child's World".  That book has tons of info focusing on
environmental allergies and others.  There is info in the back of the second
book to help you find food distributors, natural products distributors, etc.
etc. and what I found helpful , the number to Dr. Rapp's foundation where you
can call and ask for a recommendation for a like minded Dr. in your area.
Hope this is helpful.
