Describe delusional disorders, including the different types of delusions individuals with this disorder usually have, and explain how delusional disorders differ from other types of psychotic disorders, especially schizophrenia

What will be an ideal response?

Answer will include that delusional disorder is a type of psychotic disorder but that people with delusional disorders usually do not suffer from hallucinations, emotional excesses, or personality disintegration. The main feature of delusional disorders is the presence of deeply held false beliefs, which may take the following forms. In erotomanic type of delusional disorder, people have erotic delusions that they are loved by another person, especially by someone famous or of higher status. Some celebrity stalkers suffer from erotomania. In grandiose type, people suffer from the delusion that they have some great, unrecognized talent, knowledge, or insight. They may also believe that they have a special relationship with an important person or with God or that they are a famous person. If the famous person is alive, the deluded person regards her or him as an imposter. An example of the jealous type of delusion would be having an all-consuming, but unfounded, belief that your spouse or lover is unfaithful. Persecutory type delusions involve the belief that you are being conspired against, cheated, spied on, followed, poisoned, maligned, or harassed. People suffering from somatic delusions typically believe that their bodies are diseased, rotting, or infested with insects or parasites, or that parts of their bodies are defective. Although they are false, and sometimes far-fetched, all these delusions are about experiences that could occur in real life. In other types of psychosis, delusions tend to be more bizarre. For example, a person with schizophrenia might believe that space aliens have replaced all his internal organs with electronic monitoring devices. In contrast, people with ordinary delusions merely believe that someone is trying to steal their money, that they are being deceived by a lover, or that the FBI is watching them
