MULTIPLE-SCLEROSIS WITH VERY LATE-ONSET - REPORT OF 6 CASES AND REVIEW OF THE LITERATURE

Multiple sclerosis (MS) usually starts in young adulthood. However, the disease may appear late or very late in life. We report 6 cases with onset after the age of 59 years and review the literature. As in early onset disease, the diagnosis is mainly clinical. Laboratory findings and paraclinical evidence may support the diagnosis if clinical data are not sufficient. In elderly patients clinical history and laboratory data should be thoroughly appraised to exclude conditions more common in old age such as vascular diseases.
