Madhouse reveals a long-suppressed medical scandal, shocking in its brutality and sobering in its implications. It shows how a leading American psychiatrist of the early twentieth century came to believe that mental illnesses were the product of chronic infections that poisoned the brain.

Cotton’s work was controversial, yet none of his colleagues questioned his experimental practices. Subsequent historians and psychiatrists too have ignored the events that cast doubt on their favorite narratives of scientific and humanitarian progress.In a remarkable feat of historical detective work, Andrew Scull exposes the full, frightening story of madness among the mad-doctors.
