Answer

In delusional disorder, the person has a variety of paranoid beliefs, but these beliefs are not bizarre and are not accompanied by any other symptoms of schizophrenia. For example, a person who is functioning well at work but becomes unreasonably convinced that his or her spouse is having an affair has a delusional disorder rather than schizophrenia.
