Delusional Disorder

Delusional disorder is a type of serious mental illness in which a person cannot tell what is real from what is imagined. A delusion can be defined as a false belief that is based on an incorrect interpretation of reality. Individuals dealing with delusional disorder often experience non-bizarre delusions, involving situations that could occur in real life, such as being followed, poisoned, or conspired against. There are different types of delusional disorder based on the themes of the delusion experienced: 

• Erotomanic - Believing that another person, often someone famous, is in love with them. This person might attempt to contact the object of the delusion or engage in stalking. 
• Grandiose - Having an over-inflated sense of worth, power, or knowledge. 
• Jealous - Believing that their spouse or partner is unfaithful 
• Persecutory - Believing that they are being mistreated, being spied on, or going to be harmed. 
• Somatic - Believing that they have a physical defect or medical problem 
• Mixed - Having two or more of the types of delusions listed above
