A condition in which a person experiences trouble in recognizing reality is known as delusional disorder. It is a psychotic disorder that makes a person believe false interpretation of reality. Just like all other psychotic symptoms, delusions can occur as a part of many different psychiatric disorders. But, the term delusional disorder is used when delusions become most prominent.
The most common symptom of delusional disorder is a persistent delusion. The types include:
Erotomanic: This is the kind of delusion of a special, loving relationship with another person, especially who is famous or of higher standing.
Grandiose: In this, a person has a special ability or thinks they are in a special relationship with a powerful person such as the president or a celebrity.
Jealous: A delusion in which a person thinks that their sexual partner is being unfaithful.
Persecutory: A delusion that a person is being threatened or maltreated.
Somatic: A delusion of suffering from physical illness.
The disorder may go away in a short time but, it can also persist for many months or years. The inherent reluctance of a person suffering from the disorder can make the prognosis of the treatment worse.
