Neuroimmunological diseases often have a chronic course and a high socio-economic impact, as most of them occur in younger patients and result in progressing disability and loss of work force.

Treatment decision should primarily be guided by evidence from high quality clinical studies and-if available-from direct head-to-head trials and cost-effectiveness analysis.
