An inflated appraisal of one's worth, power, knowledge, importance, or identity. When extreme, grandiosity may be of delusional proportions. See also: Treatment
a symptom of mania; used to describe the larger-than-life feelings of superiority often experienced by those in a manic episode.
The patient's behaviour and speech indicate a belief that he is superior to others and/or the interviewer. It may be associated with actual delusions of grandiosity but the evidence for grandiosity comes from the patient's overall demeanor and conversation. For example, indicating that speaking to the interviewer is rather beneath him, or that he does not wish to be involved with the general "riff raff" of patients on the ward.
