The main symptom is a persistent delusion or delusions (a fixed belief) for example, about a situation, condition or action that is not happening but may be plausible in real life. Types include:

  • Erotomanic Delusion of a special, loving relationship with another person, usually someone famous or of higher standing. (This kind of delusion is sometimes at the root of stalking behavior.)

  • Grandiose Delusion that the person has a special power or ability, or a special relationship with a powerful person or figure, such as the president, a celebrity or the Pope.

  • Jealous Delusion that a sexual partner is being unfaithful.

  • Persecutory Delusion that the person is being threatened or maltreated.

  • Somatic Delusion of having a physical illness or defect.
