Abstract

Aim: This study was conducted to determine the clinical and demographic features in Iranian multiple sclerosis (MS) patients including clinical courses, positive MS family history, disability and age of disease onset. Materials & methods: All stages of the study were reported according to the PRISMA guidelines. A systematic review of published literature in Persian and English journals with a comprehensive search was conducted on English international databases including Scopus, PubMed/Medline, Cochrane Library, Science Direct, Web of Science, Embase, PsycINFO, as well as the Google Scholar search engine and national databases. Results: The prevalence of clinical courses of relapsing remitting, primary progressive, secondary progressive and relapsing progressive in Iranian patients with MS was 77.1 (95 CI: 72.2-81.3), 6.2 (95 CI: 4.1-9.2), 9.5 (95 CI: 6.8-13.1) and 0.4 (95 CI: 0.2-0.8), respectively. Positive family history of MS in Iranian MS patients was 8.9 (95 CI: 6.9-11.4). The mean age of disease onset was 28.9 years (95 CI: 27.8-30.1). Conclusion: The results of this meta-analysis in an Iranian population can provide useful information for neurologists and healthcare.
