The aim of the present poster is to describe an initial complex case of schizoaffective disorder with other clinical adverse conditions (metabolic disorders) in a young adult male, which gradually went into a positive treatment way from polipharmacy to monoteraphy. His psychiatric history started when he was 25-year-old, he was diagnosed of heroine dependence, hypercholesterolemia and hypertrigliceridemia. In 2000 he had a suicide attempt in a context of depressive mood and delusions. He needed a psychiatric hospitalization for the first time in his life and he received anti-psychotics for the first time too. Drug abuse was detected in that hospitalization (cannabis and alcohol). In 2001 was diagnosed of paranoid schizophrenia. In 2007 the diagnosis was modified to schizoaffective disorder and also was detected high blood pressure, Diabetes Mellitus II and overweight. From 2007 to the present he passed from a scheme treatment composed by four or more psychotropic drugs to monotherapy (only one psychotropic drug, an anti-psychotic), he stayed clinically stable and all his metabolic parameters remained equal or improved.
