“…Thus, the logical inference would be that a real rise of MS incidence has occurred in Tehran in the last two decades. Our prevalence found of 55.98/100,000 was lower than the figures of Greece and Turkey [10,24] but higher than in Kuwaitis, Jordanians and Chinese [8,11,25] . However, due to different inclusion criteria and variety in study methodology, a comparison of the results with these countries should be made with caution.…”

Background: The frequency of multiple sclerosis (MS) is still undetermined in Tehran. We conducted this survey to assess the incidence trend and point prevalence of MS on March 20, 2009, in Tehran province, Iran. Methods: Data for patients with a definite diagnosis of MS were obtained from the Iranian MS Society (IMSS). The annual incidence rates were calculated based on year of diagnosis. The prevalence and annual incidence rates were standardized using the WHO (2000–2025) population as a standard. Results: We detected 8,026 definite MS cases that had been registered by the IMSS till the prevalence day. The age- and sex-adjusted incidence rates increased significantly from 0.68/100,000 in 1989 to 2.93/100,000 in 2008 with its peak (4.58) in 2005. On March 20, 2009, we identified 7,896 prevalent cases (5,888 females and 2,008 males) yielding an age-adjusted prevalence rate of 50.57/100,000 (females: 77.24 and males: 25.54). The female-to-male ratio was 3.11 (95% confidence interval: 2.95–3.27). The age-specific prevalence showed a peak in the group aged 35–39 years in females and in that of 40–44 years in males with a mean (±SD) age of 35.48 (±9.9) years for females and 36.98 (±10.5) years for males. Conclusion: Tehran is a high-risk area for MS disease, and the incidence has dramatically increased over the last 20 years.

“…Table 5 shows the epidemiological studies of MS in Asia after the year 2000 ranked by prevalence. The prevalence of MS in Taiwan is lower than that of most Asian countries except China Shanghai [25] . An increase in prevalence with time is not only observed in Taiwan, but also in other Asian countries, including Japan, Hong Kong, Kuwait and Jordan [17,18,[26][27][28][29][30][31][32][33][34] .…”

Background: The purpose of the study is to investigate the epidemiology of Creutzfeldt-Jakob disease (CJD) and multiple sclerosis (MS) in Taiwan. Methods: Cases of CJD and MS were identified from the National Health Insurance Research Database from January 2000 to December 2005. Age- and sex-specific incidences of these diseases were estimated by dividing the incidence number by population data obtained from the Department of Statistics, Ministry of the Interior. Results: During the study period, 79 cases of CJD, 41 women and 38 men, were identified. The average annual incidence rate was 0.63/million. Most cases were older than 60 years. There were 1,262 cases of MS. The male-to-female ratio was 0.4. The average annual incidence rate was 0.79/100,000. The incidence reached a peak at the age group of 40–60 years for females and at the age group of over 55 years for males. The prevalence of MS was 2.96/100,000 in 2005, which is higher than those of previous studies in Taiwan. Conclusions: The annual incidence rate of CJD in Taiwan is lower than in western countries. The annual incidence rate and prevalence of MS in Taiwan are low. The prevalence of MS in Taiwan increased in recent decades.

“…In Japan, certain explanations for a decline in the mean age include more frequent utilization of MRI imaging as well as improved neurological care [17] . China Cheng et al [33] reported the MS prevalence of 1.39 per 100,000 (95% CI 1.16-1.66) in Shanghai. All studies used McDonald's criteria as diagnostic criteria among MS patients.…”

“…All studies used McDonald's criteria as diagnostic criteria among MS patients. In our reviewed studies, MS prevalence is more common among females in comparison to males [30][31][32][33]35] . In the last 2 decades, the mean age at disease onset ranged from 46.4 in 1993 to 32.6 in 2006 [31,32] .…”

Background: Multiple sclerosis (MS) is one of the most common chronic immune-mediated diseases of the human central nervous system and an important cause of non-traumatic neurologic disability among young population in several countries. Recent reports from East Asia, South East Asia and South Asia have proposed a low to moderate prevalence of MS in these countries. Methods: A literature review search was carried out in December 2014 in Medline, Embase, Scopus and Cochrane library to recover original population-based studies on MS epidemiology in East Asia, South East Asia and South Asia countries published between January 1, 1950 and December 30, 2014. We intended search strategies using the key words: multiple sclerosis, prevalence, incidence and epidemiology. Based on our inclusion criteria, 68 epidemiologic studies were included in this systematic review. Results: The most extensively used diagnostic criteria in the studies were McDonald's criteria. Most studies were performed in a multi-center hospital setting. The female to male ratio varied and ranged from 0.7 in India to 9.0 in China. The mean age at disease onset ranged from the lowest age of 25.3 in Iran to the highest age of 46.4 in China. MS prevalence ranged from 0.77 in 100,000 populations in Hong Kong (1999) to 85.80 in 100,000 in Iran (2013). Conclusions: Advances in MS registries around the globe allow nationwide population-based studies and will allow worldly comparisons between the prevalence and incidence in different regions that are provided to monitor estimation.
