Long-term survival and progression of disability in multiple sclerosis have not been studied previously in Australia. We report the findings in a cohort of 159 patients from Newcastle. Median survival time from onset of symptoms to death was 42 years. When expected survival rates are compared with those of the Australian population, there is approximately a 10% reduction in survival time in multiple sclerosis patients, after 20 years or more from disease onset. The expected time to reach DSS 3 and DSS 6 was 7 years and 27 years respectively. Survival time of multiple sclerosis patients and rate of progression of the disease are similar in the Northern and Southern Hemispheres.
