General public knowledge, attitudes, and practices with respect to epilepsy in the Batibo Health District, Cameroon

Our aim was to obtain baseline data for an epilepsy education program adapted to communities in Cameroon. We conducted 302 face-to-face interviews with patients without epilepsy, caregivers, and visitors in the Batibo District Hospital. Most respondents (99.3%) had heard or read about epilepsy, 89.7% knew someone with epilepsy, and 87.7% had witnessed a seizure. About 43% would object to associating with people with epilepsy (PWE) and 75.8% would object to their children marrying PWE, whereas 35.1% would offer PWE equal employment. Predictors of negative attitudes were: advanced age, lack of formal education, and the belief that epilepsy is hereditary, contagious, or a form of insanity. In conclusion, the high level of public awareness of epilepsy in the Batibo Health District may reflect the magnitude of the condition, contrasting with the prevalent negative attitudes. A successful epilepsy education program must take into account the beliefs and value systems of the community.

HIV-associated neurocognitive disorders in sub-Saharan Africa: a pilot study in Cameroon.

BackgroundThe disease burden of human immunodeficiency virus (HIV) - acquired immunodeficiency syndrome (AIDS) is highest in sub-Saharan Africa but there are few studies on the associated neurocognitive disorders in this region. The objectives of this study were to determine whether Western neuropsychological (NP) methods are appropriate for use in Cameroon, and to evaluate cognitive function in a sample of HIV-infected adults.MethodsWe used a battery of 19 NP measures in a cross-sectional study with 44 HIV+ adults and 44 demographically matched HIV- controls, to explore the validity of these NP measures in Cameroon, and evaluate the effect of viral infection on seven cognitive ability domains.ResultsIn this pilot study, the global mean z-score on the NP battery showed worse overall cognition in the HIV+ individuals. Significantly lower performance was seen in the HIV+ sample on tests of executive function, speed of information processing, working memory, and psychomotor speed. HIV+ participants with AIDS performed worse than those with less advanced HIV disease.ConclusionsSimilar to findings in Western cohorts, our results in Cameroon suggest that HIV infection, particularly in advanced stages, is associated with worse performance on standardized, Western neurocognitive tests. The tests used here appear to be promising for studying NeuroAIDS in sub-Saharan Africa.

Knowledge and attitudes concerning medical genetics amongst physicians and medical students in Cameroon (sub-Saharan Africa)

Purpose: Little is known about physicians knowledge of, and attitudes toward genetics in sub-Saharan Africa.Methods: Survey of 101 pre-clinical, 95 clinical medical students, and 110 physicians, in Cameroon.Results: The awareness of DNA diagnosis was poor: 0, 2.2, and 1.2%, respectively, for sickle cell anemia. The majority of the respondents considered genetic counseling as indispensable (97.6, 98.9 and 100%); and prenatal diagnosis as acceptable. The acceptance of medical abortion increased with the level of medical education (62.6, 74.7 and 90.7%). Sickle cell anemia was considered as a “serious disease” by a greater majority of respondents than Down syndrome (P < 0.001). But, in all three groups, the acceptance of termination of affected pregnancy “if the respondents own child was affected” was lower for sickle cell anemia than Down syndrome (22.4 versus 40.2%, 10.8 versus 29.3% and 36.1 versus 70.4%).Conclusions: The data suggest a poor knowledge of genetic tests among medical students and physicians. This cohort appears to accept the principles of medical genetics. Our data emphasized a need to introduce genetics and to develop research on its ethical and social implications in Cameroon.

A community survey of knowledge, perceptions, and practice with respect to epilepsy among traditional healers in the Batibo Health District, Cameroon

OBJECTIVE The purpose of this study was to gain an understanding of the approach of traditional healers to epilepsy care, in order to develop a community-based epilepsy care program in Batibo Health District. METHODS With an 18-item questionnaire, interviews were carried out with 102 traditional healers randomly selected from two associations of traditional healers in the Batibo Health District. RESULTS Most traditional healers had heard about epilepsy (98.0%), knew someone with epilepsy (97.8%), or had witnessed a seizure (92.2%). About 40% would object to their children associating with people with epilepsy (PWE), 46.1% would object to their children marrying PWE, and 51% linked the disease to insanity. Though 61.8% of the traditional healers could not offer any treatment for epilepsy, most of them thought it was treatable (74.5%) and would readily refer a patient to the hospital (95.1%). The independent predictors of attitudes were: middle age (30-49 years), P=0.00003; female gender, P=0.007; correct knowledge of the cause(s) of epilepsy, P=0.001; and the misconceptions that epilepsy is contagious and that epilepsy is a form of insanity, P=0.003 and 0.019, respectively. CONCLUSION Traditional healers constituted the focus group studied so far in Cameroon that is most familiar with epilepsy. Although they still have some negative practices, the attitudes of traditional healers toward PWE in Batibo Health District are satisfactory, compared with those of the general public and students in the same community. These findings provide evidence for the first time in Cameroon suggesting that collaboration between the modern and traditional health systems with the view of bridging the epilepsy treatment gap is possible. There is a need to train traditional healers in epilepsy care in our context.

Secondary school students' knowledge, attitudes, and practice toward epilepsy in the Batibo Health District--Cameroon.

Using a 12‐item questionnaire, we assessed knowledge, attitudes, and practice (KAP) toward epilepsy and identified determinants of inappropriate attitudes toward people with epilepsy (PWE) among 910 randomly selected secondary school students in Batibo (Cameroon). Ninety‐five percent of the students had heard or read about epilepsy, 73.3% knew an epileptic, and 76.4% had witnessed a seizure. Those who would offer equal employment opportunities to PWE, refuse to associate with, or refuse to marry PWE represented 58.6%, 25.4%, and 64.2%, respectively. Negative attitudes appeared to be reinforced by beliefs that epilepsy is hereditary (25.7%), contagious (49.9%), or a kind of insanity (38%). Acquaintance with PWE tended to improve the misconception that epilepsy is contagious (p < 0.001), and to reinforce the view that it is a form of insanity (p < 0.01). A successful epilepsy education program must account for local beliefs, and secondary school students may constitute a good channel for community education.

Validity of an interviewer-administered patient health questionnaire-9 to screen for depression in HIV-infected patients in Cameroon

BACKGROUND In high-income countries, depression is prevalent in HIV patients and is associated with lower medication adherence and clinical outcomes. Emerging evidence from low-income countries supports similar relationships. Yet little research has validated rapid depression screening tools integrated into routine HIV clinical care. METHODS Using qualitative methods, we adapted the Patient Health Questionnaire-9 (PHQ-9) depression screening instrument for use with Cameroonian patients. We then conducted a cross-sectional validity study comparing an interviewer-administered PHQ-9 to the reference standard Composite International Diagnostic Interview in 400 patients on antiretroviral therapy attending a regional HIV treatment center in Bamenda, Cameroon. RESULTS The prevalence of major depressive disorder (MDD) in the past month was 3% (n=11 cases). Using a standard cutoff score of ≥10 as a positive depression screen, the PHQ-9 had estimated sensitivity of 27% (95% confidence interval: 6-61%) and specificity of 94% (91-96%), corresponding to positive and negative likelihood ratios of 4.5 and 0.8. There was little evidence of variation in specificity by gender, number of HIV symptoms, or result of a dementia screen. LIMITATIONS The low prevalence of MDD yielded very imprecise sensitivity estimates. Although the PHQ-9 was developed as a self-administered tool, we assessed an interviewer-administered version due to the literacy level of the target population. CONCLUSION The PHQ-9 demonstrated high specificity but apparently low sensitivity for detecting MDD in this sample of HIV patients in Cameroon. Formative work to define the performance of proven screening tools in new settings remains important as research on mental health expands in low-income countries.

General public awareness, perceptions, and attitudes with respect to epilepsy in the Akwaya Health District, South-West Region, Cameroon

BACKGROUND This study was part of a series mandated by the Ministry of Public Healths National Epilepsy Control Program to obtain baseline data for a community-adapted epilepsy education program. METHODS We conducted 387 face-to-face interviews with subjects without epilepsy aged 15 years and above in 12 villages of the Akwaya Health District, Cameroon. RESULTS Most respondents (97.9%) had heard or read about epilepsy, 90.2% knew someone with epilepsy, and 90.4% had witnessed a seizure. About 51.4% would object to association with people with epilepsy (PWE), 68.7% would object to marriage to PWE, while 41.6% would offer them equal employment. For treatment, 30.2% would suggest going to a traditional healer or witch doctor, while 3.9% would not recommend any treatment at all. Predictors of attitudes were male gender, low or no level of education, having children, knowledge of the cause of epilepsy, and beliefs that epilepsy is contagious or is a form of insanity. CONCLUSION The high level of public awareness on epilepsy in the Akwaya Health District may suggest a high prevalence. This contrasts with prevailing negative attitudes. Our data provide new evidence for our hypothesis of regional variation in the determinants of epilepsy stigma in Cameroon.

NeuroAIDS in Africa

In July 2009, the Center for Mental Health Research on AIDS at the National Institute of Mental Health organized and supported the meeting “NeuroAIDS in Africa.” This meeting was held in Cape Town, South Africa, and was affiliated with the 5th IAS Conference on HIV Pathogenesis, Treatment and Prevention. Presentations began with an overview of the epidemiology of HIV in sub-Saharan Africa, the molecular epidemiology of HIV, HIV-associated neurocognitive disorders (HANDs), and HAND treatment. These introductory talks were followed by presentations on HAND research and clinical care in Botswana, Cameroon, Ethiopia, The Gambia, Kenya, Malawi, Nigeria, Senegal, South Africa, Uganda, and Zambia. Topics discussed included best practices for assessing neurocognitive disorders, patterns of central nervous system (CNS) involvement in the region, subtype-associated risk for HAND, pediatric HIV assessments and neurodevelopment, HIV-associated CNS opportunistic infections and immune reconstitution syndrome, the evolving changes in treatment implementation, and various opportunities and strategies for NeuroAIDS research and capacity building in the region.

Knowledge, attitudes and practice with respect to epilepsy among secondary school students in the Kumbo West Health District - North West Region- Cameroon

BACKGROUND The main goal of this study was to obtain baseline data on awareness and attitudes and practices with respect to epilepsy among secondary school students. METHODS We interviewed a total of 659 students from three randomly selected secondary schools in the Kumbo West Health District, using a 12-item questionnaire in English. RESULTS About 94.7% had heard about epilepsy, 25.8% had read on the subject, 55.2% knew someone with epilepsy and 77.7% had witnessed a seizure. While 37.9% of students would object to association with people with epilepsy (PWE), 47.8% would object to marriage with PWE. About 77.2% would offer equal employment to PWE although 72.7% believed there were jobs not suitable for PWE. Up to 58% of our sample thought epilepsy is contagious and about 62.2% of them declared that epilepsy is curable. Respectively 65%, 9%, and 30% would recommend a medical doctor, a traditional healer and Gods help for treatment of epilepsy. Independent determinants of attitudes were found to be: the belief that epilepsy is a form of insanity or is contagious, having witnessed a seizure, being female, being a Christian and having a higher level of education. CONCLUSION There was a high level of awareness on epilepsy and the negative attitudes observed among these students were better than those reported in the same community. The determinants of negative attitudes were found to be diversified, confirming our hypothesis of variation, and our data further suggest that the interplay between these factors may be more complex than generally thought. This requires further qualitative study.

Knowledge, attitudes and practices with respect to epilepsy among student nurses and laboratory assistants in the South West Region of Cameroon

OBJECTIVE This study was designed as part of a series of studies mandated by the Cameroon Ministry of Public Health (National Epilepsy Control Program) to obtain new data for improvement of the epilepsy teaching program in schools training health personnel in the South West Region of Cameroon. METHOD A 12-item semistructured questionnaire was self-administered to 340 student nurses and laboratory assistants in five training schools for health personnel in the South West Region of Cameroon. RESULTS All of them had heard about epilepsy, 86.5% knew someone with epilepsy, 88.5% had witnessed a seizure, but only 48.8% had read about epilepsy. About 33% and 52% would, respectively, object to their children associating with and marrying people with epilepsy (PWE). About 15.3% believed that epilepsy is a form of insanity, 10% thought epilepsy is contagious, 67.4% (P<0.001) would recommend medical treatment for epilepsy, 22% would offer prayers only, and 6% would recommend traditional medicine. Independent predictors of attitudes were: acquaintance with someone with epilepsy, knowledge of the cause of epilepsy, the belief that epilepsy is contagious or is a form of insanity, being male, and being in the first year of studies. CONCLUSION The knowledge level in this student sample is high, but the relatively low proportion of respondents who have read about epilepsy suggests that the observed high level of awareness of epilepsy may be from knowledge gained in the community; thus, there exist knowledge gaps. Therefore, a teaching course on epilepsy needs to be introduced into the curriculum of these training schools as early as the first year of studies. The course content must take into account the belief and value systems of the community and address misconceptions about epilepsy.
