As the father of two sons with schizophrenia, author Ron Powers is familiar with the pain and frustration of dealing with a chronic, incurable disease of the brain.
Powers' younger son, Kevin, was a talented musician whose struggles with schizophrenia began at age 17. Just before his 21st birthday, in 2005, Kevin took his own life.
A few years later, Powers' older son, Dean, started experiencing symptoms of schizophrenia and had a psychotic break.
Ron Powers, a Pulitzer Prize-winning journalist and media critic, wrote Flags of our Fathers, which was adapted into a film by Clint Eastwood.
"There is no greater ... feeling of helplessness than to watch two beloved sons deteriorate before [your] eyes, not knowing what to do to bring them back," Powers tells Fresh Air's Terry Gross.
