Delusional Disorders

A delusion is a fixed false belief based on an inaccurate interpretation of an external reality despite evidence to the contrary. The belief is not congruent with one’s culture or subculture, and almost everyone else knows it to be false.

A delusion is a fixed false belief based on an inaccurate interpretation of an external reality despite evidence to the contrary. The diagnosis? of a delusional disorder is made when a person has one or more non-bizarre (situations that are not real but also not impossible) delusional thoughts for one month or more that cannot be explained by any other condition. An individual’s cultural beliefs merit consideration before coming to the diagnosis. Cultural beliefs also impact the content of delusions. In patients with delusional disorder, delusions(s) do not impact the functionality and the patient’s behavior is not overtly bizarre. This activity reviews the evaluation and management of delusional disorder and highlights the role of the interprofessional team in caring for affected patients.
