From the <i>New York Times</i> best-selling author of <i>Chasing the Scream</i>, a radically new way of thinking about depression and anxiety. <br /><br />What really causes depression and anxiety - and how can we really solve them? Award-winning journalist Johann Hari suffered from depression since he was a child and started taking antidepressants when he was a teenager. He was told that his problems were caused by a chemical imbalance in his brain. As an adult, trained in the social sciences, he began to investigate whether this was true - and he learned that almost everything we have been told about depression and anxiety is wrong. <br /><br />Across the world, Hari found social scientists who were uncovering evidence that depression and anxiety are not caused by a chemical imbalance in our brains. In fact, they are largely caused by key problems with the way we live today. Hari's journey took him from a mind-blowing series of experiments in Baltimore, to an Amish community in Indiana, to an uprising in Berlin. <br /><br />Once he had uncovered nine real causes of depression and anxiety, they led him to scientists who are discovering seven very different solutions - ones that work. It is an epic journey that will change how we think about one of the biggest crises in our culture today.
