A female client is admitted with a diagnosis of delusions of grandeur. This diagnosis reflects a belief that one is:

Correct Answer: B. Highly famous and important

Delusion of grandeur is a false belief that one is highly famous and important. A 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.

• Option A: Cotard delusion is a rare condition marked by the false belief that you or your body parts are dead, dying, or don’t exist. It usually occurs with severe depression and some psychotic disorders. It can accompany other mental illnesses and neurological conditions. One of the main symptoms of Cotard delusion is nihilism. Nihilism is the belief that nothing has any value or meaning. It can also include the belief that nothing really exists. People with Cotard delusion feel as if they’re dead or rotting away. In some cases, they might feel like they’ve never existed.
• Option C: A delusion is a belief that is clearly false and that indicates an abnormality in the affected person’s content of thought. The false belief is not accounted for by the person’s cultural or religious background or his or her level of intelligence. The key feature of a delusion is the degree to which the person is convinced that the belief is true. A person with a delusion will hold firmly to the belief regardless of evidence to the contrary. Delusions can be difficult to distinguish from overvalued ideas, which are unreasonable ideas that a person holds, but the affected person has at least some level of doubt as to its truthfulness.
• Option D: A person with a delusion is absolutely convinced that the delusion is real. Delusions are a symptom of either a medical, neurological, or mental disorder.
