Alastair Santhouse knew something was wrong the night he was on call during his medical training and got the news that a woman on the way to the ER had died in the ambulance. That meant he could go back to sleep! But he couldn't. He was overtaken with the sense that his joyful reaction was terrible failure. That night began his long journey away from the ER and into psychiatry.

Head First chronicles Santhouse's many years treating patients and his exploration of the ways in which our minds exert a huge and underappreciated influence over our health. They shape our responses to symptoms that we develop, dictate the treatments we receive, and influence whether they work. They even influence whether we develop symptoms at all.

Written with brutal honesty, deep compassion, and a wry sense of humor, Head First examines difficult cases that illuminate some of our most puzzling and controversial medical issues--from the tragedy of suicide, to the stigma surrounding obesity, to the mysteries of self-induced illness. Ultimately he finds that our medical model has failed us by promoting specialization and overlooking perhaps the single most important component of our health: our state of mind.
