憂鬱是現代人的普遍疾病，而這個疾病的歷史與治療發展已有漫長的演進。 A fascinating, “rich, and generous” (Financial Times) look at the treatment of depression by an award-winning science writer that blends popular science, narrative history, and memoir. Is depression a persistent low mood, or is it a range of symptoms? Can it be expressed through a single diagnosis, or does depression actually refer to a diversity of mental disorders? Is there, or will there ever be, a cure? In seeking the answers to these questions, Riley finds a rich history of ideas and treatments—and takes the reader on a gripping narrative journey, packed with fascinating stories like the junior doctor who discovered that some of the first antidepressants had a deadly reaction with cheese.
