“Delusion of persecution: It is the most frequent content of delusion. It was distinguished from other types of delusion and other forms of melancholia by Lasegue (1852). The interfering agent may be animate or inanimate, other people or machines; may be system, organizations or institutions rather than individuals. Sometimes the patient experiences persecution as a vague influence without knowing who is responsible. May occur in conditions like: Schizophrenia, Affective psychosis: Manic, Depressive type, and Organic states: Acute, chronic. Persecutory overvalued ideas are a prominent facet of the litiginous type of paranoid personality disorder.”
