Item Spirituality and Suicidality Among Patients with Schizophrenia: A Cross-sectional Study from Nigeria(Springer Science+Business Media / Springer Nature, 2021) Esan, O. B.; Lawal, K.Studies which have explored the effect of spirituality on suicidality among patients with schizophrenia have been characterized by inconsistent results. The aim of this study was to examine the relationship between spirituality and suicidality among stable patients with schizophrenia in Nigeria. The Daily Spiritual Experience Scale was applied to measure spirituality. There was found a significant relationship between spirituality and having had suicidal thoughts in a lifetime. Spirituality was negatively correlated with the severity of negative symptoms, total positive and negative syndrome scale score (PANSS), the severity of depression, and positively correlated with functioning.Item Neurocognitive Impairments (NCI) in bipolar disorder: Comparison with schizophrenia and healthy controls(Elsevier B.V, 2020) Esan, O. B.; Oladele, O.; Adediran, K. I.; Abiona, T. O.Background: Neurocognitive impairments (NCI) are common in patients with bipolar I disorder. However, reports about the affected domains, outcomes and magnitude have been inconsistent. The aim of this study was to compare the magnitude (severity) and specificity (domains), of (NCI) in euthymic Bipolar I Disorder (BD) patients with a demographically and educationally matched sample of patients with schizophrenia in remission (SC) and healthy controls (HC). Methods: The Screen for Cognitive Impairment in Psychiatry (SCIP) was applied in this cross-sectional study, to all consecutive and consenting euthymic outpatients with bipolar I disorder (BD) (n = 76), remitted patients with schizophrenia (n = 130) and age and gender-matched healthy controls (HC) (n = 100). The cognitive tests done included Verbal List Learning-Immediate (VLT-I), Working Memory Test (WMT), Verbal Fluency Test (VFT), Verbal Learning Test-Delayed (VLT-D) and Processing Speed Test (PST). Within the bipolar group, the association between NCI and functioning was assessed. Results: There was a significant difference in the proportions of participants that had cognitive impairment from the 3 groups (37% (HC) vs. 71.1% (BD) vs. 91.5%(SC) (p=0.001) The BD group in comparison to the HCs did worse on all domains of the SCIP except WMT and PST. The BD group was not significantly different from the SC group in all neuropsychological domains of the SCIP except WMT. BD group significantly functions better than the SC group. The severity of depressive symptomatology and VLT-I were independent predictors of functioning in the BD group. Conclusion: Cognitive impairment affects almost all the neurocognitive domains of the BD group. The difference in NCI between euthymic BD patients and SC in remission are quantitative rather than qualitative.Item Modeling psychological function in patients with schizophrenia with the PANSS: an international multi-center study(Cambridge University Press, 2021) Fountoulakis, K. N.; Dragioti, E.; Theofilidis, A. T.; Wiklund, T.; Atmatzidis, X.; Nimatoudis, I.; Thys, E.; Wampers, M.; Hranov, L.; Hristova, T.; Aptalidis, D.; Milev, R.; Iftene, F.; Spaniel, F.; Knytl, P.; Furstova, P.; From, T.; Karlsson, H.; Walta, M.; Esan, O. B.; Oladele, O.; Osunbote, C.; Rybakowski, J. K.; Wojciak P.Background: The aim of the current study was to explore the changing interrelationships among clinical variables through the stages of schizophrenia in order to assemble a comprehensive and meaningful disease model. Methods: Twenty-nine centers from 25 countries participated and included 2358 patients aged 37.21 11.87 years with schizophrenia. Multiple linear regression analysis and visual inspection of plots were performed. Results: The results suggest that with progression stages, there are changing correlations among Positive and Negative Syndrome Scale factors at each stage and each factor correlates with all the others in that particular stage, in which this factor is dominant. This internal structure further supports the validity of an already proposed four stages model, with positive symptoms dominating the first stage, excitement/hostility the second, depression the third, and neurocognitive decline the last stage. Conclusions: The current study investigated the mental organization and functioning in patients with schizophrenia in relation to different stages of illness progression. It revealed two distinct “cores” of schizophrenia, the “Positive” and the “Negative,” while neurocognitive decline escalates during the later stages. Future research should focus on the therapeutic implications of such a model. Stopping the progress of the illness could demand to stop the succession of stages. This could be achieved not only by both halting the triggering effect of positive and negative symptoms, but also by stopping the sensitization effect on the neural pathways responsible for the development of hostility, excitement, anxiety, and depression as well as the deleterious effect on neural networks responsible for neurocognition.Item Sexual Dysfunction Among Patients With Schizophrenia in Southwest Nigeria(Routledge (Taylor & Francis Group), 2018) Esan, O. B.; Esan,A.Sexual functioning has received little attention as an important aspect of patient care for those suffering from schizophrenia. In Nigeria, cultural and religious factors often prevent patients from talking with their clinician about their sexual life. The aim of our study was to assess the frequency and nature of sexual dysfunction inpatients with schizophrenia and assess the determinants of sexual dysfunction in such patients. Sexual dysfunction was assessed with the Arizona Sexual Experience Scale in 90 patients with schizophrenia. Demographic and clinical characteristics including quality of life, the severity of schizophrenia, and perceived stigma were recorded using a standardized protocol and at a collection. The prevalence of sexual dysfunction was 36.7%. Higher scores on the negative subscale of the Positive and Negative Syndrome Scale (PANSS), the general subscale of the PANSS, the total scores on the PANSS, and a family history of mental illness were significantly associated with sexual dysfunction. The only significant predictor of sexual dysfunction was the severity of the negative subscale of the PANSS. This study highlights the high prevalence of sexual dysfunction among patients with schizophrenia. Efforts should be made to identify and address this problem.
