A prospective study of the incidence, prevalence and mortality of multiple sclerosis in Leeds

“…The prevalence of multiple sclerosis in Leeds (all ages crude prevalence, 97/10 5 ) was found to be similar to that in the south of the United Kingdom ((Southampton 99/10 5 ) [14]; (South East Wales 117/10 5 ) [18]; (South Cambridgeshire 130/10 5 ) [9]; (Sutton 115/10 5 ) [19]; (Sussex 111/10 5 ) [13]; (North Cambridgeshire 118/10 5 ) [15]. However, the comparison of prevalence data is confounded by the use of different classification systems, different inclusion criteria and by the use of an inappropriate standard population to take into account differences between the populations being compared, particularly their age structures.…”

Low familial risks for multiple sclerosis in Buenos Aires, Argentina

“…Of note, we found a sibling risk of 0.28% (95% CI 0.2-0.4), around 10 times lower than rates previously reported for the northern hemisphere (3.8% in the UK [2], 3.6% in Canada [17]) and in the southern hemisphere (2.13% in Australia [13]). This finding is in agreement with the 10 times lower prevalence reported in our country (17/100,000 vs 111-240/100,000 in abovementioned countries [12,18,19]). A comparison table with selected studies in the northern and southern hemisphere is provided (see Supplementary Table 2).…”

Factors in the rising prevalence of multiple sclerosis in the north-east of Ireland

“…The mean interval between onset of first symptom and diagnosis was 4.6 years with no significant difference with gender (male 4.87, female 4.46, P = 0.82). The mean duration of disease was 17.7 years (SD 12.2), with a median duration of 14 years (IQR [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25].…”
