The European Stroke Organisation (ESO) is a pan-European society of stroke researchers and physicians, national and regional stroke societies and lay organisations that was founded in December 2007. The aim of the European Stroke Organisation (ESO) is to reduce the incidence and impact of stroke by changing the ways that stroke is viewed and treated. This can only be achieved by professional and public education, and by making institutional changes. The ESO provides assistance in achieving this goal and in harmonising stroke management across the whole of Europe.
