Abstract
Objective:
To explore the effect of chronic institutionalization on cognitive performance in chronic psychiatric patients with emphasis on age disorientation, a phenomenon that was found in previous research to occur in up to 25% of chronic schizophrenic patients.
Method:
One hundred and ten chronic psychiatric patients, forming 4 main groups—schizophrenic patients, nonschizophrenic patients, institutionalized, and noninstitutionalized—were examined for age disorientation (inability to give one's chronological age correctly on request), and their Minimental State scores (MMSE) were compared across the 4 groups.
Results:
Twelve out of 43 patients (26%) who were institutionalized according to our definition were age-disoriented and had significantly lower MMSE scores than the other 3 groups. The chronic, noninstitutionalized schizophrenic group and the other chronic psychiatric patients, whether they were institutionalized or not, were negative for this phenomenon. One of the 12 age-disoriented patients was age delusional, and 5 of the 12 had a total MMSE score consistent with dementia (21 or lower).
Conclusion:
Age disorientation is a specific phenomenon that characterizes a subgroup of chronically ill and institutionalized schizophrenic patients. It is unlikely that chronicity per se or prolonged hospitalization alone will lead to cognitive impairment.
