Grandiose delusion also known as delusions of grandeur was previously known as paranoid disorder.  It is a type of delusion and is predominant among psychiatric patients.  It can also be a symptom of Schizophrenia or Bipolar disorder.  There are degrees of grandiose delusion, some believe to be Gods while some believe to be kings, others could see themselves as being famous or rich, some of them believe they are related to a deity or have some supernatural power.  Researchers have proven that grandeur disorder is more common among the highly educated people and the unmarried.

Grandiose delusion is associated with bipolar disorder, depression, drug abuse, narcissistic personality disorder, schizophrenia and many others.  It could be caused by abnormal brain structure, depression, mental disorder or drug abuse.  Whatever the cause may be, the sufferers of this delusion need our support and love to help them live a better life.

Let’s take a detailed look at what grandiose delusion is all about.


What Is Grandiose Delusion

To have a better understanding of what grandiose delusion is all about let’s briefly define delusion and grandeur.

Delusion simply means to believe or have a strong conviction of something that is not true.

Grandeur is a quality of being very large, popular or magnificent.  For instance, a famous actor might be regarded as being ‘grandiose’ in the field of acting.

Grandiose delusion is a type of delusion that makes someone find it difficult to differentiate between something that is real and his or her imaginations.  The person tends to have a false belief of being famous, powerful, omnipotent or highly placed in the society.  For instance, imagine a poor man that can barely afford his meals, wake up and start having a strong conviction that he is the richest man in the world when it is obvious that he neither has a shelter nor food to eat.  This is exactly what grandiose delusion is all about.

Causes of Delusion of the Grandeur

Researchers have really found it difficult getting a particular cause for this type of delusions.  However it seems to be associated with the brain and certain drugs used and could also be genetic.  Some of the causes of grandiose delusion include:

  1. Gene: Researchers have proven that polymorphisms of the genes, especially those associated with dopamine receptors, can lead to grandeur delusion.
  2. Injuries of the Brain: Grandiose delusions can also be caused by injuries in any part of the brain.  However, injuries around the frontal and temporal lobes have a higher tendency of leading to delusions of grandeur compared to other parts of the brain.
  3. Also abnormalities in the brain structure can also lead to grandiose delusions.
  4. Another major cause of grandiose delusions is drug abuse.  Those that abuse drugs might eventually develop delusions of the grandeur.  There are certain drugs that have the ability of affecting neurotransmitters concentration, and receptor densities.  When these drugs are used for a long term , they might destroy the brain cells and lead to grandiose delusions.
  5. Mental disorder: Psychiatric patients or people that have certain mental disorder stand the chance of having delusions of grandeur.  Researchers have proven that about 59% of people having bipolar disorder experience grandiose delusions.  Also people with paranoid schizophrenia have a higher chance of experiencing this type of delusion.
  6. Depression: Although it might seem unbelievable but depression can also cause grandiose delusions.  People with depressive disorder can, over time, experience grandiose delusions.


Symptoms of Grandiose Delusions

  • Some of them see themselves as Gods or related to a deity like God.
  • Some of them believe to be powerful especially those whose delusions are related to power.  You could see them having a strong conviction that they are highly placed in the society, president of a country or manager of a firm when obviously they are nowhere close to belonging to that caliber of people.
  • Some of them also believe that they have supernatural powers.  For instance some power based delusions of grandeur might tend to have the conviction that they can change the timing, like cause the night to become day and day to become night.
