Separate phrases, gestures, facial expressions are given special importance, as clear hints of a threat to their lives, and punish them. Patients are anxious, confused, see the pursuers in almost every counter. The behavior of patients is determined by the content of delusions and is impulsive, i.e. can be expressed by sudden unpredictable actions (attack on imaginary enemies, flight, jumping from vehicles, from a window, suicidal attempts).
Duration of psychosis - from several days to several weeks. Signs of stupefaction, as a rule, are absent.
