Dear Friends and Colleagues,   We are proud to announce that the 6th World Congress on Controversies in Neurology (CONy), will take place in Vienna, Austria, on March 8-11, 2012.   Academically our CONy Congress will raise the most dynamic and controversial topics facing clinicians in the fields of neurology in an exciting debate forum.  The Congress will promote excellence in the field by seeking to shed light on ongoing and challenging debates and to bridge gaps between the expansion of information and its consolidation in clinical practice.   Allowing ample time for speaker-audience discussion, the Congress aims at reaching up-to-date and agreed-upon answers to ongoing debates even when data remains limited, through evidence-based medicine and expert opinion.  Participants will have the opportunity to take part in this vibrant meeting which will facilitate discussions on the shared experiences and opinions of leading local and international experts.   The CONy Congress will emphasize issues related to the region in terms of epidemiology, genetics, diagnostics and clinical management, as well as typical complications and distinctive responses to treatments. We invite you to participate in our CONy Congress in the beautiful city of Vienna. Sincerely, Prof. Michael Brainin, Austria & Prof. Amos Korczyn, Israel CONy Co-Chairpersons
