Pediatric bipolar disorder causes diagnostic challenges due to having similarities to signs of a normal child development as well as due to occuring clinical features of mania episodes in adolescence and finally because of a frequent overlap of symptoms together with other comorbid disorders that occur within this age group. The authors of the research present a follow-up case report which emphasises the challenges of differential diagnoses between pediatric bipolar disorder and schizophrenia spectrum disorders where during the first episode psychotic features prevail. The research describes the case of a 15-year-old boy where due to the occuring psychotic symptoms manic symptoms revealed themselves because of an insufficient antipsychotic treatment. One year later once the maintainance treatment had been ended the psychosis episode reoccured together with rapid mood swings. As a result, a mixed type schizoaffective disorder had been diagnosed.
