Fear and depression during the COVID-19 outbreak in Cameroon: a nation-wide observational study.

BACKGROUND: The COVID-19 pandemic has been associated with significant psychological and social distress worldwide. We investigated fear and depression among adults in Cameroon during different phases of the COVID-19 outbreak. METHODS: An online survey was conducted in Cameroon from June-December 2020 using a structured questionnaire. Socio-demographic data and information regarding COVID-19 history were obtained. Fear and depressive symptoms were assessed using the Fear of COVID-19 score (FCV-19S) and the Patient Health Questionnaire (PHQ-9), respectively. Responses were clustered in weeks to better appreciate their evolution over time. RESULTS: Overall, 7381 responses from all ten regions of Cameroon were analysed (median age: 30 years, 73.3% male). The prevalence of depression (PHQ-9 score ≥ 10) was 8.4%, and that of high fear of COVID-19 (FCV-19S scores ≥19) was 57.4%. These rates were similar across genders, age-groups, and region of residence. While mean weekly PHQ-9 scores remained fairly stable throughout the study period (range: 2.53-3.21; p = 0.101), mean FCV-19S scores were highest during the early weeks but decreased significantly thereafter (from 20.31 to 18.34; p <  0.001). Multivariate analyses revealed that having a postgraduate degree, a history of quarantine, flu-like symptoms during the past 14 days, and higher FCV-19S scores were associated with more severe depressive symptoms, while obtaining COVID-19 information from various sources reduced the odds for depression. CONCLUSION: Depression amidst the COVID-19 crisis is less prevalent in Cameroon than in other countries. Prompt and widespread dissemination of adequate COVID-19 information may reduce the risks for depression by dispelling fear and anxiety among Cameroonians.

Incidence and prevalence of epilepsy and associated factors in a health district in North-West Cameroon: A population survey.

This population-based cross-sectional survey with a follow-up case-control study assessed the prevalence, incidence, and risk factors for epilepsy in a rural health district in the North-West Region of Cameroon. Community-based epilepsy screening targeted all inhabitants, six years and older, in all 16 health areas in the Batibo Health District. During door-to-door visits, trained fieldworkers used a validated questionnaire to interview consenting household heads to screen for epilepsy in eligible residents. Trained physicians subsequently assessed people with suspected seizures. After clinical assessment, they confirmed or refuted the diagnosis and estimated the date of epilepsy onset. A trained nurse interviewed people with epilepsy and randomly selected healthy individuals, obtaining relevant demographic details and information on exposure to risk factors for epilepsy. Out of 36,282 residents screened, 524 had active epilepsy. The age-standardized prevalence of active epilepsy was 33.9/1,000 (95% CI: 31.0-37.1/1,000). We estimated the one-year age-standardized epilepsy incidence at 171/100,000 (95%CI: 114.0-254.6). Active epilepsy prevalence varied widely between health areas, ranging between 12 and 75 per 1,000. The peak age-specific prevalence was in the 25-34 age group. In adults, multivariate analysis showed that having a relative with epilepsy was positively associated with epilepsy. Epilepsy characteristics in this population, geographical heterogeneity, and the age-specific prevalence pattern suggest that endemic neurocysticercosis and onchocerciasis may be implicated. Further investigations are warranted to establish the full range of risk factors for epilepsy in this population.

Epilepsy in a health district in North-West Cameroon: Clinical characteristics and treatment gap.

INTRODUCTION: Epilepsy is a common yet misunderstood condition in Cameroon, including in the Batibo Health district. METHODS: This cross-sectional study describes epilepsy clinical characteristics, the treatment gap, and associated factors in a rural district in Cameroon. After screening for epilepsy using a door-to-door survey, physicians confirmed suspected cases of epilepsy. Detailed information on the medical, seizure, and treatment history was collected from everyone with epilepsy, followed by a general and neurological examination. RESULTS: We diagnosed 546 people with active epilepsy (at least one seizure in the previous 12 months). The mean age of people with active epilepsy was 25.2 years (SD: 11.1). The mean age at first seizure was 12.5 years (SD: 8.2). Convulsive seizures (uncertain whether generalized or focal) were the most common seizure types (60%), while 41% had focal-onset seizures. About 60% of people had seizures at least monthly. One-quarter of participants had had at least one episode of status epilepticus. Anti-seizure medication (ASM) was taken by 85%, but most were receiving inappropriate treatment or were non-adherent, hence the high treatment gap (80%). Almost a third had had seizure-related injuries. Epilepsy was responsible for low school attendance; 74% of school dropouts were because of epilepsy. CONCLUSION: The high proportion of focal-onset seizures suggests acquired causes (such as neurocysticercosis and onchocerciasis, both endemic in this area). The high epilepsy treatment gap and the high rates of status epilepticus and epilepsy-related injuries underscore the high burden of epilepsy in this rural Cameroonian health district.

COVID-19 Preventive Behaviours in Cameroon: A Six-Month Online National Survey.

Since March 2020, the Cameroonian government implemented nationwide measures to stall COVID-19 transmission. However, little is known about how well these unprecedented measures are being observed as the pandemic evolves. We conducted a six-month online survey to assess the preventive behaviour of Cameroonian adults during the COVID-19 outbreak. A five-point adherence score was constructed based on self-reported observance of the following preventive measures: physical distancing, face mask use, hand hygiene, not touching one's face, and covering the mouth when coughing or sneezing. Predictors of adherence were investigated using ordinal logistic regression models. Of the 7381 responses received from all ten regions, 73.3% were from male respondents and overall mean age was 32.8 ± 10.8 years. Overall mean adherence score was 3.96 ± 1.11 on a scale of 0-5. Mean weekly adherence scores were initially high, but gradually decreased over time accompanied by increasing incidence of COVID-19 during the last study weeks. Predictors for higher adherence included higher age, receiving COVID-19 information from health personnel, and agreeing with the necessity of lockdown measures. Meanwhile, experiencing flu-like symptoms was associated with poor adherence. Continuous observance of preventive measures should be encouraged among Cameroonians in the medium- to long-term to avoid a resurgence in COVID-19 infections.

Epilepsy-associated neurocognitive disorders (EAND) in an onchocerciasis-endemic rural community in Cameroon: A population-based case-control study.

BACKGROUND: Epilepsy affects at least 50 million individuals worldwide, especially in sub-Saharan Africa (sSA). Cognitive impairment is common in people with epilepsy (PWE) yet, little is known on the burden of cognitive impairment in people with epilepsy in sSA. This study was thus designed to assess cognitive impairment in PWE or epilepsy-associated neurocognitive disorders (EAND) in a rural population in Cameroon. METHODS: This was a case-control study including PWE and age/sex-matched healthy controls from July to September 2017 in Bilomo, a village in the Mbam and Kim Division. The Montreal Cognitive Assessment (MoCA), International HIV Dementia Scale (IHDS), Dubois' Five Word testing, Frontal Assessment Battery (FAB), Isaac's Set Test and the Clock drawing test were administered to the study participants to evaluate global and specific cognitive functions. RESULTS: Eighty participants were included (40 cases and 40 controls) with a mean age of 25.78 years. Using the MoCA, 87.5% of cases had cognitive impairment, against 37.5% of controls (p < 0.001; OR 11.67; CI 3.40-45.09). Using the IHDS, the prevalence of global cognitive impairment was 84.6% among the cases against 40% for the controls (p = <0.001; OR 7.07; CI 2.29-29.19). Specifically, executive function deficits (92.5% of cases vs 40.0% of controls p = <0.001 OR = 18.50 CI; 4.48-105.08) and decreased verbal fluency (100% of cases against 45% of controls p < 0.001) were the most affected cognitive domains. Longer duration of epilepsy and higher seizure frequency were associated with global cognitive impairment. Low level of education was associated with both decreased verbal fluency and executive dysfunction while a longer stay in Bilomo correlated with poor results on the Isaac's Set Test. CONCLUSION: The prevalence of cognitive impairment appears to be much higher in PWE in the Mbam valley, particularly decreased executive function and verbal fluency, than in people without epilepsy. Longer disease duration, higher seizure frequency, low level of education and length of stay in Bilomo are associated with poorer cognitive performance. More studies are needed to refine evaluation tools to better characterize and manage EAND in sSA.

Zoonotic and vector-borne parasites and epilepsy in low-income and middle-income countries.

Zoonotic and vector-borne parasites are important preventable risk factors for epilepsy. Three parasitic infections - cerebral malaria, Taenia solium cysticercosis and onchocerciasis - have an established association with epilepsy. Parasitoses are widely prevalent in low-income and middle-income countries, which are home to 80% of the people with epilepsy in the world. Once a parasitic infection has taken hold in the brain, therapeutic measures do not seem to influence the development of epilepsy in the long term. Consequently, strategies to control, eliminate and eradicate parasites represent the most feasible way to reduce the epilepsy burden at present. The elucidation of immune mechanisms underpinning the parasitic infections, some of which are parasite-specific, opens up new therapeutic possibilities. In this Review, we explore the pathophysiological basis of the link between parasitic infections and epilepsy, and we consider preventive and therapeutic approaches to reduce the burden of epilepsy attributable to parasitic disorders. We conclude that a concerted approach involving medical, veterinary, parasitological and ecological experts, backed by robust political support and sustainable funding, is the key to reducing this burden.

Parasites and epilepsy: Understanding the determinants of epileptogenesis.

There is a large body of evidence suggesting that parasites could be a major preventable risk factor for epilepsy in low- and middle-income countries. We review potentially important substrates for epileptogenesis in parasitic diseases. Taenia solium is the most widely known parasite associated with epilepsy, and the risk seems determined mainly by the extent of cortical involvement and the evolution of the primary cortical lesion to gliosis or to a calcified granuloma. For most parasites, however, epileptogenesis is more complex, and other favorable host genetic factors and parasite-specific characteristics may be critical. In situations where cortical involvement by the parasite is either absent or minimal, parasite-induced epileptogenesis through an autoimmune process seems plausible. Further research to identify important markers of epileptogenesis in parasitic diseases will have huge implications for the development of trials to halt or delay onset of epilepsy.

Health service provision for people with epilepsy in sub-Saharan Africa: A situational review.

BACKGROUND: Epilepsy is a public health issue in sub-Saharan Africa (SSA) where many people with the condition receive no treatment. Health-care services for epilepsy in this region have not been comprehensively assessed. We examined key features of epilepsy health services provided in SSA. METHODOLOGY: This was a scoping review conducted using pre-specified protocols. We implemented an electronic search strategy to identify relevant citations using PUBMED, EMBASE, Web of Science, Scopus, Cumulative Index to Nursing and Allied Health Literature (CINAHL), African Index Medicus (AIM), Open Grey, Cochrane database, and Google Scholar. Articles eligible for full-text review were screened and data of interest were reported. RESULT: The search identified 81 eligible articles, forty-nine from East Africa, 19 from West Africa, 8 from South Africa, and 5 from Central Africa. A variety of care services were identified, with reporting of rural epilepsy care in 75% of retrieved articles mainly from East and South African countries. The majority of the rural epilepsy clinics were health worker- or nurse-led, reporting good seizure control in about two-thirds of patients using phenobarbital as the most commonly prescribed antiepileptic drug. Funding for rural epilepsy care came mainly from external donor agencies. CONCLUSION: We attempted to provide a 'snapshot' of epilepsy care services in SSA. The successes achieved in some of the centers are due to the use of existing primary health-care systems and employing non-physician health-care personnel. The true picture of epilepsy care coverage is not apparent due to the lack of data and proper health system structure in most parts of SSA. As more individuals begin to receive care, the long-term funding for epilepsy care in African countries will depend on the commitment of their respective governments.

Epilepsy and cysticercosis in Northwest Cameroon: a serological study.

PURPOSE: The prevalence of epilepsy in Cameroon is higher than that of the industrialized world and other developing countries. Neurocysticercosis due to Taenia solium infestation has been reported as a major cause of epilepsy in some parts of Cameroon although there are some conflicting data. The prevalence of epilepsy is especially high in the Momo division of the North-West Province of Cameroon. We hypothesized that individuals with epilepsy in this region have a higher percentage of seropositivity to T. solium than matched controls. METHODS: We conducted a case-control study in the Momo subdivision of Ngie. Individuals with epilepsy were recruited from the health centers in Ngie. Control subjects were selected from 19 Ngie villages. Potential cases of people with epilepsy (PWE) were identified through a questionnaire applied by trained field workers, using history of epileptic seizures as a key indicator. Blood samples were taken from all consenting individuals by finger prick, stored in StabilZyme Select, and assayed for antibodies to T. solium in an Atlanta based reference laboratory. RESULTS: We accrued 249 patients with epilepsy, of whom 237 met the inclusion criteria, and 245 age-matched controls. There was no significant difference in seropositivity to T. solium between those individuals with epilepsy (5%) and controls (4.9%). CONCLUSIONS: Our data do not support the hypothesis that epilepsy is associated with seropositivity to T. solium. It is highly unlikely that cysticercosis plays a causative role in the high prevalence of epilepsy in this region of Cameroon.

Knowledge of Pregnant Women on Mother-to-Child Transmission of HIV in Yaoundé.

INTRODUCTION: Mother-to-child transmission of HIV is a major public health problem in Cameroon. The aim of this study was to assess knowledge of pregnant women on HIV transmission and prevention, particularly the four pillars of mother-to-child transmission. MATERIALS AND METHODS: This was a descriptive cross-sectional study from October 2008 to January 2009 at the Yaoundé Gynaecology-Obstetrics and Pediatric Hospital. All women presenting at the Ante-Natal Care (ANC) Clinic for the first time were included in the study after obtaining a verbal informed consent. RESULTS: The ages of the 260 women included in the study ranged from 15 to 42 years. Almost 99% (257/260) of the women interviewed had heard about HIV. Respectively, 80.5% (209/260), 89.3% (232/260) and 81.2% (211/260) of the women cited pregnancy, delivery, and breastfeeding as risk periods for HIV transmission from mother to child. Use of the male condom, the female condom, abstinence, and faithfulness to a single partner were considered as effective methods of HIV prevention by 73% (190/260), 76% (198/260), 88% (229/260) and 46% (120/260) of respondents respectively. About 79% (64/81) of participants with higher education considered HIV infection to be contagious as opposed to 45.5% (5/11) of women with no formal education (P = 0.008). CONCLUSION: Our data suggest that women have some good knowledge on the Prevention of Mother-To-Child Transmission (PMTCT) of HIV. Nevertheless, improving the formal educational level of these women may contribute to a further reduction of HIV transmission.

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 God's 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.

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.

A survey of public knowledge, attitudes, and practices with respect to epilepsy in Badissa village, centre region of Cameroon.

OBJECTIVE: The aim of this study was to assess knowledge, attitudes, and practices (KAP) with respect to epilepsy in Badissa, as part of a series of studies mandated by the Cameroon Ministry of Public Health. METHOD: We interviewed 164 subjects face-to-face during a door-to-door survey. RESULTS: All of the subjects had heard about epilepsy; 98.8% knew at least one patient with epilepsy, and 97.6% had seen at least one epileptic seizure. With respect to attitudes, 16% and 32% would respectively prevent their children from associating with and marrying, people with epilepsy; 55.5% would offer people with epilepsy equal employment. The independent determinants of attitudes were the belief that epilepsy is a form of insanity (P=0.004) or is caused by a mental illness (P=0.003), having read about epilepsy (P=0.018), and being married (P=0.007). CONCLUSIONS: Our study demonstrates a high level of awareness and fairly good knowledge of epilepsy, a lower level of misconceptions, and better attitudes, in the study area confirming our hypothesis of a regional variation in these characteristics. This model of care may be useful in scaling up the epilepsy education program in Cameroon.

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.

Public awareness, perceptions, and attitudes with respect to epilepsy in Ebolowa and Sangmelima--Urban Cameroon.

Within the framework of a series of studies mandated by the Ministry of Public Health of Cameroon to obtain baseline data for an epilepsy education program adapted to our communities, we interviewed 456 subjects without epilepsy in the Ebolowa Regional and Sangmelima District Hospitals. We found that 99.6 and 72.6% had heard or knew a person or people with epilepsy (PWE) and 76.8% had seen a seizure. About 58% of respondents would offer equal employment opportunities to PWE; 39.6% and 33.6% would respectively object to their children associating with or marrying PWE; 13% associated epilepsy with insanity and witchcraft, whereas 82.5% would recommend modern treatment for epilepsy. Predictors of negative attitudes were the beliefs that epilepsy is hereditary (26.3%) and epilepsy is a form of insanity (13%). Familiarity with epilepsy in Ebolowa and Sangmelima is high, and attitudes toward PWE are better there than in other areas of Cameroon. These results demonstrate a regional variation in public awareness and attitudes toward epilepsy and suggest that urban populations may constitute targets as well as channels for epilepsy sensitization campaigns in Cameroon.

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 Health's 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.

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.
