Discovery of AIDS retrovirus (HTLV-III [human T-cell leukemia virus]) simultaneously by research groups at Pasteur Institute and National Cancer Institute in Bethesda (Desowitz, 181-184). Publication of DSM-IV: “. . . the psychiatric tradition and sociopolitical considerations seem to have played the major roles in shaping this document. . . Very different symptoms are included under the rubric of ‘schizophrenia’ mainly because they have always been grouped together, rather than because of any new scientific evidence that they share a common etiology. In fact, schizophrenia seems to be a ‘catch-all’ disorder for any serious thought disorder, as long as a number of specific factors such as age, brain damage, toxins, generalized dementia, or an overriding mood disorder can be ruled out” (Valenstein, 158-163; quoted at 161).
