[Prognosis after diagnosis of multiple sclerosis].

- Even at a young age, multiple sclerosis often profoundly impacts a patient's daily activities.- Treatment is complicated because disease course is different for each patient.- Early treatment has the best results, in the short term as well as the long term, but the most effective treatments can have severe and sometimes irreversible side effects and are very costly.- It is therefore important to determine the prognosis at an early stage, in order to limit increasing future invalidity with appropriate treatment.- For this literature review, we have examined short- and long-term disease course as well as possible prognostic factors.
