Overview
Delusional Disorder is a type of mental health condition in which a person holds persistent false beliefs, called delusions, despite evidence to the contrary. The delusions can be of any type, such as persecution, jealousy, grandiosity, or somatic, but they are not a symptom of other mental health conditions, such as schizophrenia or bipolar disorder.
Delusional Disorder typically develops slowly over time, and individuals with the condition generally have functioning, coherent behavior, with the exception of their delusions. People with Delusional Disorder may have trouble recognizing that their beliefs are false and may experience significant distress and disruption in their personal and professional lives as a result of their delusions.
The exact cause of Delusional Disorder is not well understood, but it is thought to be related to a combination of genetic, neurological, and environmental factors.
Diagnosis of Delusional Disorder is made through a comprehensive evaluation by a mental health professional, who will consider the individual's symptoms, medical history, and other factors to determine if the criteria for the condition are met.
