paraphrenia
     n : 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
         [syn: {paranoid schizophrenia}, {paranoic type
         schizophrenia}, {paraphrenic schizophrenia}]
