A further prevalence study of multiple sclerosis in north-east Scotland

Abstract

A second epidemiological study of multiple sclerosis (MS) in north-east Scotland has confirmed that the area has the highest prevalence rate in the world for any population of comparable size. On 1 December 1973 the prevalence was 144 per 100,000 population. The age and sex specific prevalence rates are the highest ever recorded, one in every 306 of the population aged 40 to 59 years being affected. All patients have been tabulated in the National Health Service Central Register to facilitate future studies. The MS mortality rate in north-east Scotland is similar to the rate for the whole of Scotland. Throughout most of Scotland, therefore, MS probably is as prevalent as it is in the north-east.
