Do beliefs about causation influence attitudes to mental illness?
(Elsevier Ltd., 2006-06) Gureje, O.; Olley, O.; Ephraim-Oluwanuga, O.; Kola, L.
Studies indicate that stigmatizing attitudes to mental illness are rampant in the community worldwide. It is unclear whether views about the causation of mental disorders identify persons with more negative attitudes. Using data collected as part of a community study of knowledge of and attitudes to mental illness in Nigeria, we examined the relationships between views about causation and attitudes. Persons holding exclusively biopsychosocial views of causation were not different from those holding exclusively religious-magical views in regard to socio-demographic attributes, and the two groups were not very dissimilar when general knowledge of the nature of mental illness was compared. However, religious-magical views of causation were more associated with negative and stigmatizing attitudes to the mentally ill. Findings demonstrate the challenge of developing and delivering an educational program to change public attitudes to mental illness.
Do Young Schizophrenics with Recent onset of Illness Show Evidence of Hypofrontality?
(1994) Gureje, O.; Olley, O.; Acha, R. A.; Osuntokun, B. O.
Young schizophrenic patients (n = 43), manic controls (n = 32), both groups diagnosed according to the Research Diagnostic Criteria and on remission from acute illness, and 53 normal subjects were given a battery of neuropsychologic tests selected to assess different functional areas in the brain. Compared with normal controls, patient groups showed evidence of impaired functioning of many cortical areas but with the schizophrenics having the worst performance. In addition, schizophrenic patients performed poorly in tests designed to assess frontotemporal cortical functioning. This pattern of deficits differentiated schizophrenics from both manic and normal subjects. The results suggest that widespread cognitive deficits are a feature of both schizophrenia and mania but that frontal lobe dysfunction may be more specific to the former. It would also appear that these impairments are not artefacts of age, chronicity or of institutionalization, and are present even in schizophrenic patients who may have an illness with putative better outcome than those studied in previous reports.
Premorbid Functioning in Schizophrenia: A Controlled Study of Nigerian Patients
(W. B. Saunders Company, 1994) Gureje, O; Aderibigbe, Y. A; Olley, O.; Bamidele, R. W.
We compared the premorbid social adjustment of 38 schizophrenic patients with that of 20 manic patients. Even though the small sample size affected the number of significant differences obtained, schizophrenic patients consistently showed evidence of poorer premorbid functioning than manics at various stages of social development. Schizophrenic men also tended to have functioned more poorly than women. Poor premorbid functioning was associated with negative syndrome, but not with positive or disorganization syndromes. Our findings suggest that poor premorbid adjustment is an early sign of schizophrenic illness even among patient populations who may be characterized by good short-term outcome.
