Clinically isolated syndromes with no further disease activity suggestive of multiple sclerosis at the age of population life expectancy

• The proportion of patients with clinically isolated syndrome (CIS) reported to convert to clinically definite multiple sclerosis varied between 30 and 75%. We studied the lifetime probability of remaining in the "CIS only" condition. The study was based on the longitudinally followed Gothenburg 1950-1964 incidence cohort (n = 306). Survival analysis revealed that 17.8% of 236 attack onset patients remained "CIS only". Patients with afferent (optic and sensory) symptoms had a better prognosis with approximately 30% of these patients remaining "CIS only". Patients who had experienced no relapse during the first 25 years remained "CIS only" for the subsequent 25 years of follow-up.
