title: Age disorientation in Kraepelinian schizophrenia: frequency and clinical correlates.
abstract: Many schizophrenic patients exhibit significant neuropsychological impairment, and age disorientation is considered to be one of the more extreme manifestations. To evaluate clinical correlates of age disorientation with reference to the course of schizophrenic illness, we compared 39 deteriorated chronic Kraepelinian schizophrenic patients and 39 nondeteriorated schizophrenic patients early in the course of illness. Age disorientation was observed in 36% of patients in the Kraepelinian group, but in no patient in the non-Kraepelinian group. In the Kraepelinian group, age disorientation was unrelated to positive/negative symptoms or illness duration. Our data suggest that age disorientation may be a function of aging in schizophrenia, but is not merely a function of chronicity.
