Daniel Gibbs dedicated his career as a neurologist to the study of Alzheimer’s and care for patients living with the disease. Then he was diagnosed with Alzheimer’s himself. Gibbs says that early diagnosis has allowed him to slow the progression of the disease through diet, exercise and other treatment. A documentary based on the book he wrote about his experience, “Tattoo on my Brain,” is airing on June 22 at OHSU. Gibbs and his wife, Louis Seed, join us to talk about living with Alzheimer’s.
