What can be more devastating for parents than to learn that their child is autistic? The severely debilitating neurological disorder, which affects social and language development, can be difficult to treat. When her son was diagnosed with autism at 19 months, Seroussi, a small-business owner and wife of a research chemist, determined to do everything in her power to help her child achieve normal functioning. In addition to pursuing recommended speech and behavior modification therapies for her son, Seroussi devoted her considerable energies--often against medical advice--to researching alternative approaches. Her own experience and a growing body of scientific evidence pointed to connections between autism and diet. And though the theory has not yet been proven, Seroussi says, research now suggests that autism may be an autoimmune disorder triggered in rare cases by an infant's measles-mumps-rubella immunizations. Convinced that the inability to digest certain proteins was contributing to her son's condition and that his autism was related to his reaction to MMR vaccines, Seroussi eliminated suspect foods from his diet; he made such dramatic improvement that, by age four, he was functioning normally. Now a crusader for dietary intervention, Seroussi has written a book that will give hope to many families--though she cautions that not every autistic child responds to such treatment. She includes a FAQ section, gluten- and casein-free recipes and resources, and a list of organizations and readings. Agent, Kathi Paton. (Feb.)
