paraphrenia

(noun) a form of schizophrenia characterized by delusions (of persecution or grandeur or jealousy); symptoms may include anger and anxiety and aloofness and doubts about gender identity; unlike other types of schizophrenia the patients are usually presentable and (if delusions are not acted on) may function in an apparently normal manner.
