[Apropos of delusions of grandeur in general paresis: considerations in 1 case].

Nowadays diagnosis of neurosyphilis has become an infrequent event. Furthermore, the few patients studied have a clinical picture different from that described in the past. We report the clinical evolution of a patient with general paresis who suffered from delusions of grandeur, a clinical feature almost disappeared in these times. This mental disorder did not change after prolonged phenothyazines treatment. Among possible causes that made delusions of grandeur disappear in general paresis, remarkable improvements in therapy and major changes in social life should be considered.
