I am aware of the DSM-III requirement regarding the maximum age at onset of schizophrenia. In fact, my article contained the following sentence: "The sex difference was probably attenuated by the DSM-III requirement that either the prodromal or active phase of the illness begin before the age of 45 years." Prior to the age of 45 years, the patients referred to by Dr Orlosky who had the onset of their psychosis or first treatment or hospitalization after the age of 45 years met at least two of the eight prodromal symptoms listed by the DSM-III. Please note that the requirement reads: "Onset of prodromal or active phase of the illness before age 45," not "prodromal and active phase" (italics added).
