Incidence and prevalence of neurological disorders in the United Arab Emirates: a systematic review

Abstract

Background/Objectives: The United Arab Emirates (UAE) is a rapidly developing country. With the increase in average life expectancy, high rates of consanguinity, and the adoption of a Western lifestyle, the burden of neurological disorders is expected to increase over the next few decades. Despite the importance of neurological disorders, there has not been a systematic review of published studies on the epidemiology of neurological disorders in the UAE.

Methods: We searched for studies of incidence and/or prevalence of neurological disorders in the UAE published in English in MEDLINE, Google Scholar, Embase, and Scopus databases with no date restrictions up until 01 October 2023. Two authors independently assessed abstracts and full texts of possibly relevant papers, followed by data extraction from studies satisfying the eligibility criteria.

Results: Eight articles (N=2067 patients) were included, half reported incidence and prevalence of multiple sclerosis, with an average crude prevalence 56/100,000 and related demyelinating disorders. Others were related to headache, meningitis, cerebral venous thrombosis, and brain tumours.

Conclusion: There is a distinct lack of data on the epidemiology of diferent neurological diseases in the UAE. Large population-based studies, ideally longitudinal, are required to provide accurate and reliable estimates of the incidence and prevalence of neurological disorders to help inform healthcare capacity planning.
