Delusion of Grandeur

boy looking bigger than he isA delusion of grandeur is the false belief in one’s own superiority, greatness, or intelligence. People experiencing delusions of grandeur do not just have high self-esteem; instead, they believe in their own greatness and importance even in the face of overwhelming evidence to the contrary. Someone might, for example, believe they are destined to be the leader of the world, despite having no leadership experience and difficulties in interpersonal relationships. Delusions of grandeur are characterized by their persistence. They are not just moments of fantasy or hopes for the future.

Symptoms of Delusion of Grandeur

Delusions of grandeur vary greatly in their content, but they are similar to one another in that they involve the persistent believe in one’s own grandiosity. Common examples of delusions of grandeur include:

  • Belief that one has a special relationship with a supernatural entity. Cult leaders, for example, might believe they can communicate with a god or that they are a manifestation of a god on earth.
  • Belief that one has a special relationship with a famous person or authority figure, such as the president.
  • Belief that one has a unique destiny. These destinies often involve power, fame, fortune, or supernatural concepts.

Causes of Delusion of Grandeur

Delusions of grandeur are associated with narcissistic personality disorder (NPD), which is a mental health diagnosis listed in the Diagnostic and Statistical Manual of Mental Disorders (DSM). A narcissistic personality may cause people to greatly overestimate their own importance and believe in their own uniqueness. These delusions can also be symptomatic of schizophrenia. Some people with schizophrenia experience delusions in which they believe they are a hugely powerful person or have a great gift to give to the world.

Treatment for Delusion of Grandeur

Treatment of delusions depends upon the underlying cause. It is important for practitioners to differentiate between delusions of grandeur and simple hopes for the future. A person, for example, who wants to be president one day is likely not experiencing a delusion of grandeur. A combination of talk therapy and medication can be helpful in treating delusions of grandeur. Depending upon the delusion’s cause, antidepressants, anti-anxiety medications, and/or antipsychotic medications may be prescribed.

    I have a daughter who is 47 and believes with all her heart and soul that she is a Messiah. She has been diagnosed with schizoaffective disorder, boarder line, depression, and BiPolar. She tried med’s many years back and said they gave her too many side affects, and were of no help for her. Now she thinks she is God and is not sick so she doesn’t need to go to a Dr. or get help. Her diagnosis is a new one as I talked her into getting on disability after being homeless and not working for years. How can I get her help when she thinks she is fine?
