Neurocognitive deficiencies are a fundamental trait of schizophrenia and the studies have shown the occurrence of such deficiencies in the first psychotic episode, both in the case of adults and of early onset psychosis. Twenty-seven children and adolescents (n=27) at their first psychotic episode were enrolled and they represent the study group. They were assessed during their hospitalization in the Clinic of Pediatric Psychiatry, Cluj-Napoca. The control group was set of thirty two (n=32) healthy children and adolescents, students in public schools, volunteers. The neurocognitive functioning was assessed with Trail Making A and Trail Making B, with verbal fluency tests, with the Wisconsin Card Sorting Test and with Rey Auditory Verbal Learning Test. Our results show weaker global cognitive performances with adolescents at their first psychotic episode than the healthy subjects and specific cognitive deficiencies in the area of verbal fluency, attention, processing speed and executive function.
