The author summarizes a monograph study on the course of schizophrenia into old age, which he co-authored with C. Muller, & which includes mortality & cause-of-death statistics on 1,642 original cases & an average of 37 years of catamnestic observation of the 289 patients who survived until the final followup examination. The long term course for schizophrenics was favorable in at least half of the cases.
