[Social and economic impact of multiple sclerosis]

The evolution of multiple sclerosis is unforeseeable; it can induce disability and fatigue; thus, it has a socio-economical impact. Married and family life, relationships and work are the most affected areas. Financial problems can also occur. Counselling and aid services must be provided. All these social impacts induce an indirect cost which is the major component of the total cost of multiple sclerosis. Data show that there are great differences between countries and that the cost increases when there is a disability. The economic impact of the "new" drugs is unknown and must be assessed.
