Delusional disorder is characterized by the presence of either bizarre or non-bizarre delusions which have persisted for at least one month. Non-bizarre delusions typically are beliefs of something occurring in a person’s life which is not out of the realm of possibility. Delusional disorder is a psychiatric condition in which a person has non-bizarre delusions. A delusion is a firmly held belief about something which is not based in reality. The person continues to hold the belief despite evidence or proof to the contrary, and even though no one else has that belief. Font Size. A. A. A. Delusional disorder, previously called paranoid disorder, is a type of serious mental illness called a psychosis in which a person cannot tell what is real from what is imagined. The main feature of this disorder is the presence of delusions, which are unshakable beliefs in something untrue. 1 Residual schizophrenia -- a person is no longer experiencing delusions or hallucinations, but has no motivation or interest in life. 2  Schizoaffective disorder --a person has symptoms of both schizophrenia and a major mood disorder such as depression. Delusional disorder shares some of the symptoms of schizophrenia, but it is a different type of mental illness. People with delusional disorder, like some people with schizophrenia, often have delusions. The types of delusional disorder include: 1  Erotomanic: Someone with this type of delusional disorder believes that another person, often someone important or famous, is in love with him or her. 2  The person might attempt to contact the object of the delusion, and stalking behavior is not uncommon. Unlike schizophrenia, delusional disorder usually does not cause hallucinations. Individuals with this condition tend to retain organized thinking. They are also usually emotionally expressive, and report feelings that are consistent with their perception of what is going on in the world.
