Epilepsy in Older People in Sub-Saharan Africa: A Systematic Review

Epilepsy among the older population of sub-Saharan Africa: Analysis of the global burden of disease database

INTRODUCTION

Epilepsy is considered one of the most burdensome neurologic diseases by the World Health Organization due to the high risk of morbidity and mortality. Few studies have investigated the epidemiology of idiopathic epilepsy in Sub-Saharan Africa (SSA). This study aims to characterize the disease burden of epilepsy among the older population in SSA via a large international database.

METHODS

Descriptive epidemiological data from the Global Burden of Disease (GBD) database was collected for idiopathic epilepsy in all regions of SSA. The "older" population was defined as 55 years of age and above. The variables of interest included mortality, incidence, prevalence, and disability-adjusted life years (DALYs) rates per one hundred thousand populations.

RESULTS

The average mortality rate was highest in Western SSA (6.34 per 100,000), and all regions were significantly higher than the global average (p < 0.001). DALYs and incidence rates of idiopathic epilepsy in all regions of SSA were significantly higher than the global averages (p < 0.01). Globally, the older population had a significantly higher mortality rate than the younger population (2.78 vs 1.62, respectively; p < 0.01). The older population had a higher mortality rate than the younger population in each region of SSA (p < 0.01). Conversely, for DALYs, the younger population had a higher disease burden than the older population globally and in each region of SSA (p < 0.01).

CONCLUSION

This study is the first to examine the epidemiologic profile of idiopathic epilepsy in the older population in SSA. Our results indicate that, when compared with the global population, older adults in SSA suffer a greater disease burden and mortality. This study reports the immense need for increased resources and awareness regarding epilepsy in the elderly population of Africa.

Unlocking the hidden burden of epilepsy in Africa: Understanding the challenges and harnessing opportunities for improved care

Background

Epilepsy is a common neurological disorder that affects many people in Africa, yet the burden of the disease is often hidden. The management of epilepsy in Africa is often inadequate due to a lack of awareness and education, limited access to diagnostic tools and treatments, inadequate coordination of care, and the stigma associated with the condition.

Method

A comprehensive literature review was conducted to gather information on the epidemiology, diagnosis, management, and outcomes of epilepsy in Africa. The review included studies from peer-reviewed journals, government reports, and gray literature.

Results

The review revealed a high burden of epilepsy in Africa. The studies also showed a significant gap in the availability and accessibility of diagnostic tools, antiepileptic drugs, and specialized therapies such as physical, occupational, and speech therapy. Additionally, the review found that cultural beliefs and practices, socioeconomic factors such as poverty and lack of access to healthcare, and the stigma associated with the condition, also pose significant challenges to managing epilepsy in Africa.

Conclusion

The study highlights the urgent need for improved epilepsy management in Africa. Additionally, the study calls for further research on epilepsy in Africa and collaboration between all stakeholders to improve the management of epilepsy in Africa.

Status of epilepsy in the tropics: An overlooked perspective

Epilepsy is one of the most common serious chronic neurological diseases affecting people of all ages globally. It is characterized by recurrent seizures. About 50 million people worldwide have epilepsy. Indubitably, people with epilepsy (PWE) may be without access to appropriate treatment. Many studies have examined the molecular mechanisms and clinical aspects of epilepsy; nonetheless, the treatment gap exists in some special areas. In the tropics, the specific geographical and ecological conditions and a lack of medical resources result in neglect or delay of diagnosis for PWE. Herein, we summarized the epidemiology of epilepsy in the tropics and discussed the disease burden and existing problems, aiming to offer a medical environment for patients in need and highlight the importance of reducing the epileptic disease burden in tropical countries.

Cognitive functioning and prevalence of seizures among older persons in Uganda: A hospital-based, cross-sectional study

There is limited data on the prevalence of seizures and dementia among older persons in Uganda. We evaluated cognitive functioning, and the prevalence and factors associated with seizures among older persons attending an outpatient medical clinic in Uganda. We randomly selected older adults (60 years and above) attending Kiruddu National Referral Hospital medical outpatient clinics between October 2020 and March 2021. We excluded individuals with a history of head injury, brain tumors, mental retardation, co-morbidity with HIV and patients who have had recent brain surgery. Cognitive functioning was assessed using the Identification for Dementia in Elderly Africans (IDEA) tool. We enrolled 407 participants, with a median (inter-quartile range) age of 67 (64-73) years. Majority were female (n = 292, 71.7%). The prevalence of seizure was 1.5% (95% confidence interval [CI]: 0.7-3.3). All 6 participants reported generalized tonic-clonic seizure type. Self-reported seizure was associated with being female (adjusted prevalence ratio [aPR]: 0.79, 95%CI: 0. 67-0.93, P = .02) and residing in Mukono district (aPR: 17.26, 95%CI: 1.64-181.55, P = .018). Overall, 114 (28.1%) participants had cognitive deficit; 9 (2.2%) dementia and 105 (25.9%) impaired cognition. Cognitive deficit was independently associated with female gender (aPR: 0.61, 95%CI: 0.44-0.85, P = .003), formal employment (aPR: 0.53, 95%CI: 0.35-0.81, P = .003), age 70-74 (aPR: 1.69, 95%CI: 1.00-2.86, P = .049), and ≥ 75 years (aPR: 2.81, 95%CI: 1.71-4.61, P = .001). Prevalence of seizures among participants with cognitive deficit was 5.3% (6/114). Among older persons attending a medical clinic in Uganda, almost one-third had cognitive deficit with seizure prevalence being higher among these individuals.
