DELUSIONAL DISORDER AND SHARED PSYCHOTIC DISORDER
Discuss the Delusional and Shared Psychotic Disorder
A delusion develops in an individual in the context of a close relationship with another person(s), who has an already-established delusion. The delusion is similar in content to that of the person who already has the established delusion. The disturbance is not better accounted for by another psychotic disorder (e.g., schizophrenia) or a mood disorder with psychotic features and is not due to the direct physiological effects of a substance (e.g., a drug of abuse, a medication) or a general medical condition. Delusion is a false belief based on incorrect inference about external reality that is firmly sustained despite what almost everyone else believes and despite what constitutes incontrovertible and obvious proof of evidence to the contrary. The belief is not one ordinarily accepted by other members of the person's culture or subculture. When a false belief involves a value judgment, it is regarded as a delusion only when the judgment is so extreme as to defy credibility. Delusional conviction occurs on a continuum and can sometimes be inferred from an individual's behavior. It is often difficult to distinguish between a delusion and an overvalued idea, in which case the individual has an unreasonable belief or idea but does not hold it as firmly as is the case with a delusion.
