Consensus on early intervention in schizophrenia.

organized by Barbara Cornblatt and her colleagues at Hillside Hospital, provided an opportunity to discuss our different perspectives on early intervention in psychosis and in conditions that resemble its prodrome. In light of the recent Schizophrenia Bulletin (October 2001) article by Warner ("The Prevention of Schizophrenia: What Interventions Are Safe and Effective?") and our subsequent exchange of views in letters to the editor (Schizophrenia Bulletin, 28(1), January 2002), we feel it could be valuable to outline our areas of agreement. Although we continue to differ in our interpretation of the duration of untreated psychosis (DUP) research, and whether it shows that longer DUP leads to increased morbidity and a worse course of illness, we concur that there are many other reasons to intervene early in psychotic disorders: decreased social disruption for the patient and the family; maintenance of family ties, friendships, job, studies , accommodations, and self-respect; and reduced risk of criminal behavior, substance use, and suicide. We agree that it is unnecessary to invoke the notion of biological toxicity due to prolonged untreated psychosis, because failure to treat a sustained psychotic disorder is likely to lead to psychosocial toxicity. We concur that optimal treatment interventions should begin as early in fully declared psychosis as possible. These interventions should include ensuring security; low-dose antipsychotic drug treatment in most cases; individual and family education and support; comprehensive case management and psychosocial rehabilitative efforts to ensure adequate housing, income, and job opportunities for the patient; and a positive, recovery-oriented approach to the illness. Comprehensive, or even adequate, treatment services for first episode patients are not universally available , and early intervention focuses attention on optimal treatment and increases the prospects for improving treatment services more broadly. The positivistic approach of early intervention encourages optimism about the treatment of schizophrenia, increases community awareness, assists in stigma reduction, and boosts the involvement of consumer advocates. It is congruent with programs to promote knowledge about and understanding of mental illness and primary prevention efforts, such as improving obstetric care for women with schizophrenia. We recognize that post-illness early intervention efforts are categorically different from subthreshold intervention approaches and that the latter may have negative consequences for false-positive cases—those who are treated as if they are likely to develop the illness, but, in fact, will not. We note, however, that treatment of symptoms that resemble the positive symptoms of the schizophrenia prodrome with antipsychotic medication can …
