Abstract

In this study, 56 patients affected by schizophreniform disorder (SFD), as their first lifetime mental disorder, were re-evaluated 7.9+/-4.7 yrs (2-17 yrs) after their first hospitalization. At follow-up, schizophrenia (SC) was diagnosed in 25 patients (46%), a mood disorder (MD) in 19 (35%), a non-SC psychotic disorder in 10 (18%) and no disorder in 2 (4%). The evolution towards SC was predicted by the presence of blunted affect (OR: 1.88) and by poor pre-morbid functioning (OR: 1.10) at the index hospitalization. Our data suggest that SFD may represent the first psychotic presentation of different disorders and the evolution towards SC or a MD seems to be influenced by the pre-morbid level of functioning and by the presence of blunted affect.
