delusion is a false belief that is maintained despite overwhelming evidence to the contrary. Beliefs associated with religion or with widespread social norms within a particular culture are not considered delusions, and beliefs based upon incomplete or incorrect information also do not qualify as delusions.


Delusions can include a wide variety of false beliefs, but they frequently involve elements of magic, conspiracy, or power. For example, a person might suffer from the delusion that the pope is trying to kill them, that fairies regularly steal their socks, or that they are the deposed leader of France.

There are four main types of delusions: bizarre, non-bizarre, mood-congruent, and mood-neutral. Bizarre delusions are those that are considered highly implausible or very odd. An example of a bizarre delusion would be the belief that aliens removed a person’s internal organs without leaving any marks or scars. Non-bizarre delusions, such as the belief that the President of the United States has contacted an individual to ask for their input about an important matter, may be possible but are still highly unlikely

Mood-congruent delusions are directly related to a person’s current mood. For example, a person with depression may believe everybody hates them, while an individual experiencing a period of mania may believe they are famous. Mood-neutral delusions, on the other hand, are not related to a person’s emotional state.


Schizophreniadementia, and some brain injuries can cause delusions. Chronic substance abuse may lead to both delusions and hallucinations. When there are no other symptoms, or when the cause of the delusion is unclear, a person may be diagnosed with a delusional disorder. To qualify for this diagnosis according to the DSM-IV, a person must not have a mood disorder and must not be experiencing hallucinations or flattened affect. While people with delusional disorders may not necessarily hallucinate, they may experience auditory or tactile stimulation related to the delusion.


Therapy and in some cases medications (including antipsychotics and antianxiety medications) can treat a diagnosed delusional disorder. However, treatment is difficult without the cooperation of the person experiencing the delusion, and some people with delusions can be quite adamant that their delusions are real.


Mental health practitioners treating delusions must be extremely sensitive to cultural and religious contexts. Beliefs that might seem quite strange are often commonplace in certain societies. For example, the belief that a totem has magical powers or that a man died for the sins of all humanity may seem delusional to some individuals, but these are normal–and often normative–beliefs in some cultures. Improper treatment for beliefs that are not actual delusions can be harmful and unethical.

A delusion is a firmly held idea that a person has despite clear and obvious evidence that it isn’t true. Delusions are extremely common in schizophrenia, occurring in more than 90% of those who have 

Delusions of reference – A neutral environmental event is believed to have a special and personal meaning. For example, you might believe a billboard or a person on TV is sending a message meant specifically for you. 

Delusions of persecution – Belief that others, often a vague “they,” are out to get you. These harassing delusions often involve bizarre ideas and plots (e.g. “Martians are trying to poison me with radioactive particles delivered through my tap water”).

Delusions of grandeur – Belief that you are a famous or important figure, such as Jesus Christ or Napoleon. Alternately, delusions of grandeur may involve the belief that you have unusual powers, such as the ability to fly.

Delusions of control – Belief that your thoughts or actions are being controlled by outside, alien forces. Common delusions of control include thought broadcasting (“My private thoughts are being transmitted to others”), thought insertion (“Someone is planting thoughts in my head”), and thought withdrawal (“The CIA is robbing me of my thoughts”).
