Sociocultural and psychological features of perceived stigma reported by people with epilepsy in Benin

Purpose:  Stigma is a major burden of epilepsy. In sub‐Saharan Africa the few studies that addressed epilepsy stigma emphasize enacted, rather than perceived, stigma. This inattention may compromise clinical management and delay help seeking, thereby contributing to the treatment gap. We assessed perceived stigma and identified sociocultural and psychological factors explaining greater stigma among people with epilepsy (PWE) in Benin.

Cognitive Impairment and Dementia in Elderly People Living in Rural Benin, West Africa

Background/Aims: Dementia is increasing as a priority public health problem because of the ageing of the world population. Our goal was to estimate dementia and cognitive impairment prevalence in an elderly population of rural Benin. Methods: In a door-to-door survey, elderly people aged 65 years and above were screened using the Community Screening Interview for Dementia and the Five-Word Test. Results: The prevalence of cognitive impairment was 10.4% and that of dementia was 2.6%. Age, current depressive disorder and absence of the APOE ε2 allele were significantly associated with cognitive impairment. Conclusion: Prevalence of dementia and cognitive impairment appears to be lower in this study than in developed countries.

Ankle-brachial index as a marker of cognitive impairment and dementia in general population. A systematic review.

OBJECTIVE To investigate the association between a low ankle-brachial index (ABI) and several grades of cognitive disorders: cognitive impairment, dementia and Alzheimers disease (AD), in the general population. METHODS We performed a systematic review of the literature, including all prospective, longitudinal or cross-sectional studies assessing both peripheral artery disease (PAD), defined by a low ABI, and cognitive function. RESULTS 12 publications were included in this review, of whom 6 reported cross-sectional analysis and 6 reported longitudinal analysis. All except one reported a significant association between a low ankle-brachial index and cognitive impairment, dementia or AD. Beyond cognitive impairment, patients with PAD are at an increased risk to develop dementia or Alzheimers disease. CONCLUSION In this review, we confirm that a low (<0.90) ABI can be considered as a marker of cognitive impairment and dementia. ABI provides independent and supplemental information on subjects susceptibility to develop cognitive disorders, along its usefulness to predict cardiovascular diseases (CVD). Given its availability, easiness, safety to patients and low cost, the ABI could be useful in clinical practice and research in the field of cognitive diseases.

Specific psychological and behavioral symptoms of depression in patients with dementia

Behavioral and psychological symptoms in dementia (BPSD) are very common, with 90% of patients experiencing at least one during the course of the disease. One‐third of persons with dementia have depressive symptoms, and concomitant BPSD are very likely.

Prevalence of dementia in elderly living in two cities of Central Africa: the EDAC survey.

Background: Data on dementia from low- and middle-income countries are still necessary to quantify the burden of this condition. This multicenter cross-sectional study aimed at estimating the prevalence of dementia in 2 large cities of Central Africa. Methods: General population door-to-door surveys were conducted in the districts of Bangui (Republic of Central Africa) and Brazzaville (Congo) in elderly aged ≧65 years. The subjects were screened with the Community Screening Interview for Dementia and the Five-Words Test. Diagnosis of dementia was made according to the DSM-IV criteria and to the clinical criteria proposed by the NINCDS-ADRDA for Alzheimer’s disease. Results: We enrolled 496 subjects in Bangui and 520 in Brazzaville. The prevalence of dementia was estimated at 8.1% (95% CI = 5.8–10.8) in Bangui and 6.7% (95% CI = 4.7–9.2) in Brazzaville. Conclusion: The prevalence of dementia in urban areas of Central Africa is close to those observed in high-income countries.

Psychosocial issues in people with epilepsy in Togo and Benin (West Africa) II: Quality of life measured using the QOLIE-31 scale

PURPOSE This study in Togo and Benin, West Africa, was aimed at measuring health-related quality of life (HRQOL) of people with epilepsy (PWE). METHODS It was a cross-sectional study among 281 adult PWE in Togo and 215 in Benin matched with the same number of controls without epilepsy, using the Quality Of Life in Epilepsy Scale-31 (QOLIE-31). RESULTS In Togo and Benin, controls had significantly better HRQOL (80.3+/-7.4, 72.2+/-12.7) than PWE (49.5+/-14.4, 52.1+/-33.4) according to the QOLIE-31 Overall score (P<0.0001). HRQOL was, in general, negatively correlated with a higher frequency of seizures and lack of treatment. CONCLUSION Results call for specific management of epilepsy in PWE in Togo and Benin to improve their HRQOL.

Psychosocial issues in people with epilepsy in Togo and Benin (West Africa) I. Anxiety and depression measured using Goldberg’s scale

PURPOSE This study in Togo and Benin, West Africa, was aimed at measuring depression and anxiety among people with epilepsy (PWE). METHODS This cross-sectional study of 281 adult PWE in Togo and 215 in Benin matched with the same number of controls without epilepsy used Goldbergs anxiety and depression scale. The statistical tests used for comparisons were chi(2) tests, Fishers exact test, analysis of variance, and Fishers PLSD test when necessary. RESULTS PWE in Togo and Benin had significantly higher (P<0.0001) average depression scores (4.4+/-2.1, 4.7+/-2.7) than controls (0.5+/-0.9, 1.4+/-2.4). They also had significantly higher (P<0.0001) average anxiety scores (5.3+/-2.0, 6.2+/-2.1) than controls (2.5+/-1.6, 1.6+/-2.0). In consideration of the thresholds of the scale, the prevalence of possible major anxiety and depression among PWE was also very high compared with controls (P<0.0001). High anxiety and depression scores were, in general, positively correlated with a higher frequency of seizures and lack of treatment. CONCLUSION Results confirmed the existence of anxiety and depression among PWE in Togo and Benin.

Prevalence of dementia among elderly people living in Cotonou, an urban area of Benin (West Africa)

Background/Aims: The population of Benin is, like those of most developing countries, aging; dementia is therefore a major concern. Our goal was to estimate the prevalence of dementia in an elderly population living in urban Benin. Methods: In a cross-sectional community-based study, people aged 65 years and above were screened using the Community Screening Interview for Dementia and the Five-Word Test. Results: The prevalence of dementia was 3.7% (95% CI 2.6–4.8) overall. The figure increased with age and was higher among women than men. Conclusion: Dementia was slightly more prevalent than previously reported in a rural area of Benin, but the rate was similar to that recorded in other cities in developing countries.

Knowledge of epilepsy in the general population based on two French cities: Implications for stigma

The objective of this study was to assess the knowledge and attitudes of people living in two French counties. The data were collected from 1777 adults in the general population who were interviewed. Knowledge of and attitudes toward epilepsy in these French samples proved largely favorable: 90.6% identified epilepsy as different from a mental disorder or lunacy, and 79.2% correctly identified epilepsy as a brain disorder. The majority agreed with the statements that people with epilepsy should have the opportunity to get married and that children with epilepsy should be allowed to go to school with others. However, gaps in knowledge and erroneous beliefs prevailed, notably among men, old people, and individuals with low levels of education. This study yielded encouraging results. However, further studies are needed to confirm these findings and gain a better understanding of the contribution of French public knowledge to the causative factors generating stigma in France.

Factors Associated with Dementia Among Elderly People Living in Two Cities in Central Africa: The EDAC Multicenter Study

Risk factors for dementia in American and European countries have been well investigated. However, little research has been carried out in sub-Saharan Africa, where life events as well as environmental, socio-economic, and modifiable risk factors (i.e., cardiovascular risk factors) may differ. Two cross-sectional surveys were conducted in representative samples of the older general population living in Bangui (Central African Republic) and Brazzaville (Congo). Dementia was defined according to the DSM-IV criteria. Multivariate regression analyses were performed in order to identify independent factors associated with dementia. Among the 977 elderly Africans included in this analysis, 75 (7.6%) were diagnosed as having dementia. Increasing age, female gender, hypertension, a body mass index <18.5 kg/m2, depressive symptoms, and the lack of a primary education were significantly associated with dementia. Among life events, the death of one parent during childhood and recently having moved house were also associated with dementia. Beyond the usual risk factors for dementia, this study highlights the role of stressful events in low-income countries. Factors associated with dementia in African countries seem different from established factors in high-income countries and require further investigation.
