Comment on E.F. Torrey and R.H. Yolken: "Psychiatric genocide: Nazi attempts to eradicate schizophrenia" (Schizophr Bull. 2010;36/1:26-32) and R.D. Strous: "psychiatric genocide: reflections and responsibilities" (Schizophr Bull. Advance access publication on February 4, 2010; doi:10.1093/schbul/sbq003).

Torrey and Yolken wonder whether the killing of mentally ill persons in Nazi Germany reduced the risk for schizophrenia in the following generation. Epidemiological data from Germany do not permit reliable comparisons. Torrey and Yolken point out that horrible crime is still only little known.
