Abstract

Highlights: In Arab countries, there is a huge gap in epidemiological studies focusing on epilepsy. The median lifetime prevalence of epilepsy in the Arab world was estimated to be 6.9 per 1000. Family history and consanguinity are among the most important risk factors for epilepsy in the Arab world. Abstract: Objective: To describe the prevalence, incidence, and risk factors of epilepsy in Arab countries. Methods: In this systematic review, electronic databases including PubMed, ProQuest Public Health and Cochrane Library were searched to identify relevant English articles published until April 2020. The search was conducted to cover all 22 Arab countries. Studies were eligible for inclusion if they assessed any of these epidemiological parameters of epilepsy: prevalence, incidence, and/or risk factors and focused on at least one of the Arab countries. The quality of the studies was evaluated using standardized quality assessment tools. Results: Twenty-nine articles met the inclusion criteria. Out of the 22 Arab countries, only 11 were found to have published studies reporting on the epidemiology of epilepsy. The median lifetime prevalence of epilepsy in Arab countries was found to be 6.9 per 1000. The median incidence is 89.5 per 100000. The most frequently identified risk factors were parental consanguinity, family history of epilepsy, and a history of perinatal infections/insults. Conclusion: The prevalence and incidence of epilepsy varies in Arab countries. The most frequently reported risk factor is parental consanguinity. The lack of epidemiological studies on epilepsy in half of the Arab countries calls for more studies on this aspect to identify the burden and risk factors of epilepsy in this region.
