One morning, Jenny McCarthy sensed something was wrong and ran into her two-year-old son Evan’s room to discover he was having a seizure. In that moment, Jenny was thrust into the midst of a medical odyssey. After numerous misdiagnoses and many harrowing, life-threatening episodes, Evan was finally diagnosed with autism. But Jenny didn’t know what to do next and soon found herself alone, without any resources except for her determination to help her son.

At last, she discovered a combination of behavioral therapy, diet, and supplements that became the key to saving Evan from autism. Here, she shares her experiences and knowledge and offers a roadmap for other concerned parents.
