Frequency and clinical patterns of multiple sclerosis in Arab countries: a systematic review.

The susceptibility of various populations to multiple sclerosis (MS) and the clinical patterns of the disease are thought to be different. Nineteen articles related to incidence, prevalence and clinical patterns of MS in Arab populations were identified by keyword searching of Medline and Embase, and review of references in all relevant papers. Data were only available for the Kuwaiti, Jordanian, Libyan, Saudi, Iraqi, Palestinian (including Arabs living in Israel), and Omani populations.
