Treatment of psychosis: 30 years of progress

Thirty years ago, psychiatrists had only a few choices of old neuroleptics available to them, currently defined as conventional or typical antipsychotics, as a result schizophrenics had to suffer the severe extra pyramidal side effects. Nowadays, new treatments are more ambitious, aiming not only to improve psychotic symptoms, but also quality of life and social reinsertion. Our objective is to briefly but critically review the advances in the treatment of schizophrenia with antipsychotics in the past 30 years. We conclude that conventional antipsychotics still have a place when just the cost of treatment, a key factor in poor regions, is considered. The atypical antipsychotic drugs are a class of agents that have become the most widely used to treat a variety of psychoses because of their superiority with regard to extra pyramidal symptoms. We can envisage different therapeutic strategies in the future, each uniquely targeting a different dimension of schizophrenia, be it positive, negative, cognitive or affective symptoms.
