Some children inherit the family nose. Autumn Stringam and her brother Joseph inherited bipolar disorder, a severe mental illness that led to the suicides of their mother and grandfather. Autumn was in a psychiatric hospital on suicide watch by the time she was 22. Joseph, at 15, was prone to violent episodes so terrifying that his family feared for their lives. But after Autumn and Joseph began taking a nutritional supplement developed by their father - and based, incredibly, on a formula given to aggressive hogs - their symptoms disappeared, and today they both lead normal, productive lives.A Promise of Hope is the story of Autumn's flight from madness to wellness and an astonishing scientific account of a treatment that has also helped thousands of others. It is a powerful call for a new understanding of mental illness, its causes and its treatments.
