Just a few key excerpts from the Cleveland Clinic link I shared earlier…
What causes delusional disorder?
As with many other psychotic disorders, the exact cause of delusional disorder is not yet known. Researchers are, however, looking at the role of various genetic, biological, and environmental or psychological factors.
-
Genetic. The fact that delusional disorder is more common in people who have family members with delusional disorder or schizophrenia suggests there might be a genetic factor involved. It is believed that, as with other mental disorders, a tendency to develop delusional disorder might be passed on from parents to their children.
-
Biological. Researchers are studying how abnormalities of certain areas of the brain might be involved in the development of delusional disorders. An imbalance of certain chemicals in the brain, called neurotransmitters, also has been linked to the formation of delusional symptoms. Neurotransmitters are substances that help nerve cells in the brain send messages to each other. An imbalance in these chemicals can interfere with the transmission of messages, leading to symptoms.
-
Environmental/psychological. Evidence suggests that delusional disorder can be triggered by stress.Alcohol and drug abuse also might contribute to the condition. People who tend to be isolated, such as immigrants or those with poor sight and hearing, appear to be more vulnerable to developing delusional disorder.
How is delusional disorder treated?
Treatment for delusional disorder most often includes medication and psychotherapy (a type of counseling); however, delusional disorder is highly resistant to treatment with medication alone. People with severe symptoms or who are at risk of hurting themselves or others might need to be in the hospital until the condition is stabilized.
Psychotherapy is the primary treatment for delusional disorder. It provides a safe environment for patients to discuss their symptoms while encouraging healthier and more functional attitudes and behaviors.
Psychosocial treatments. Various psychosocial treatments can help with the behavioral and psychological problems associated with delusional disorder. Through therapy, patients also can learn to control their symptoms, identify early warning signs of relapse, and develop a relapse prevention plan. Psychosocial therapies include the following:
-
Individual psychotherapy can help the person recognize and correct the underlying thinking that has become distorted.
-
Cognitive-behavioral therapy (CBT) helps the person learn to recognize and change thought patterns and behaviors that lead to troublesome feelings.
-
Family therapy can help families deal more effectively with a loved one who has delusional disorder, enabling them to contribute to a better outcome for the person.
Medications : The primary medications used to attempt to treat delusional disorder are called anti-psychotics.
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.
