What is the outlook for people with delusional disorder?

The outlook for people with delusional disorder varies depending on the person, the type of delusional disorder, and the person’s life circumstances, including the availability of support and a willingness to stick with treatment.

Delusional disorder is typically a chronic (ongoing) condition, but when properly treated, many people with this disorder can find relief from their symptoms. Some people recover completely and others experience episodes of delusional beliefs with periods of remission (lack of symptoms).

Unfortunately, many people with this disorder do not seek help. It often is difficult for people with a mental disorder to recognize that they are not well. They also might be too embarrassed or afraid to seek treatment. Without treatment, delusional disorder can be a life-long illness.
