Delusional Disorder Disease

uncommon mental disease

one or more non-unusual recurring delusional ways of thinking

In the Diagnostic and Statistical Manual of Mental Disorders ( DSM ) Delusional Disease is defined as at least one month of delusions without any other psychotic symptoms. It is a serious type of mental illness called psychosis(Delusional Disorder, n.d.).

The six sub-types of Delusional Disorder are:

  • grandiose-believes they are the greatest, smartest,richest, strongest and fastest person ever

  • erotomanic- believes that someone is in love with them

  • jealous- believes their partner is cheating on them

  • persecutory- someone they are close to is being harmed

  • somatic-believes they have a disease or medical condition

  • mixed- more than one of the previous types listed

The Causes of this Disorder are; Genetic, Biological and Enviromental

More females than males suffer from this disease

Symptoms of Delusional Disorder Disease are;

hallucinations, no memory loss and feeling of exploitation. There are no other real symptoms that could help others identify the disorder in others. An absence in strange behavior is very common (Mental health: A state of well-being, n.d.).


The diagnosis of Delusional Disorder Diseases are crucial because when someone has a Delusional Disease, it means they have an underlying illness that needs further specific treatment. Anti-psychotic medications can be helpful, but delusions sometimes do not get better with pharmacological treatment. Psychotherapy and cognitive therapy is helpful in treatment because the goal in treatment is to get the patients attention away from their delusion and onto something else.

Delusional Disorder Disease is more frequent in elderly citizens in recent years. The age ranges from 18-90. It is still unclear how many adults suffer from this disease because most patients are in denial and do not seek out help. It is common around the world and is prevalent in people who remove themselves from society.
