Psychotic Symptoms

According to DSM-5, psychotic manic episodes assign an individual to BP I status, whereas hypomanic states (intrinsic to BP II) lack psychotic features. In BP II depressive episodes, psychotic features are uncommon, albeit with lifetime prevalence estimates ranging considerably – from 3 to 45%.[69] When present, they tend to be mood congruent (e.g. guilt, nihilism) and more enduring. By contrast, some 75% of BPD patients experience transient dissociative and paranoid symptoms[70] but rarely having a depressive theme.
