What are the complications of delusional disorder?

People with delusional disorder might become depressed, often as the result of difficulties associated with the delusions. Acting on the delusions also can lead to violence or legal problems; for example, a person with an erotomanic delusion may stalk or harass the object of his or her delusion, which could lead to arrest. Further, people with this disorder can eventually become alienated from others, especially if their delusions interfere with or damage their relationships.
