Background: Schizophrenia (SZ) and bipolar disorder (BD) are traditionally distinguished on the basis of progressive
deterioration and long-term outcome, but a more dimensional approach is warranted. There are limited data on the occurrence of
manic symptoms in patients with schizophrenia. The aim of the current study was to search for patterns in the clinical
symptomatology, which may suggest the presence of one or several mood disorders under the label of schizophrenia.
Subjects and methods: Hundred-seventy-five patients diagnosed with schizophrenia according to DSM-5 were included in the
study. The psychometric assessment included the Positive and Negative Syndrome Scale, Young Mania Rating Scale, The Montgomery-
Åsberg Depression Rating Scale and the Calgary Depression Scale. The statistical analysis included MANOVA, Pearson
Correlation coefficient and principal components analysis.
Results: Significant subthreshold manic symptoms were present in 25.14% of patients. Mood symptoms correlated with positive
symptoms. The PCA revealed a complex structure with 15 factors (one positive, negative, somatic, anxiety, neurocognitive, disorganization
and manic, five depressive and three psychomotor/excitement/hostility/violence).
Conclusion: Psychotic mood disorders are often phenotypically indistinguishable from schizophrenia, so it is likely that
psychotic affective patients have been misdiagnosed with schizophrenia. The current study suggests that there seem to be patients
with mania misdiagnosed as 'schizophrenics' because of the presence of psychotic features, a condition better described as
'schizophreniform bipolar disorder'.
