Eugen Bleuler: centennial anniversary of his 1911 publication of Dementia Praecox or the group of schizophrenias.

In 1911, a book was published in Europe by Eugen Bleuler describing in detail asylum patients under his care who met clinical criteria for the psychotic disorder named Dementia Praecox by Emil Kraepelin. Bleuler's voluminous publication, now a classic to world psychiatry, validated Kraepelin's observations and extended them in ways that remain familiar to us a full century later in how we describe, diagnose, treat, and understand psychosis.
