The psychotic episode with DSPS has similar pattern with paranoid syndrome of Kandinsky–Clérambault. Although, the structure of the syndrome is varying, and characterized by predominance of hallucinatory or delusion symptoms. According to these varieties two different types of DSPS were identified, which were observed in continuous or paroxysmal course of disease. The forms of destructive delusional behavior were also different for both of these types.
