Welcome to the 4th European Headache and Migraine Trust International Congress 2014, in Copenhagen, the premier international event for neurologists, physicians, scientists, researchers, and international experts and healthcare professionals with an interest in migraine and headache disorders.The four day programme continues to build on its basic and clinical science content by covering the latest available research, therapies, and developments from internationally recognised leaders in the field. The aim of this Congress is to provide a better understanding of migraine, tension-type headache, trigeminal autonomic cephalalgias and other headache disorders as well as trigeminal pain worldwide and to give participants the opportunity to gather new scientific evidence and understanding for improving diagnosis and treatment for patients.Poster presentations are a key feature of EHMTIC2014 and the programme has been planned to allow ample time for poster viewing and chaired discussions with an emphasis on interaction across all sessions. We will feature the best of our developing researchers in the New Scientist lectures, an opportunity to hear what is happening at the absolute cutting edge.Three Teaching Courses are scheduled prior to the start of the main programme offer focused updates for primary care practitioners and others with special interest in the field of headache; an educational case-based interactive session aimed at clinical staff to update their knowledge and learn about new therapies; and a course aimed at trainees interested in novel techniques and developments in migraine research.We will finish with a public session for patients with migraine and headache disorders, providing an overview of the Congress presentations.The sponsored satellite symposia are also an important part of the programme and we encourage you to attend these sessions to learn about the latest developments from our healthcare industry partners.On behalf of the International Scientific Advisory Committee, we would like to express our grateful thanks to the exhibitors and generous sponsors of the Congress, the EHMTIC Board, The Migraine Trust, EHF Board, the abstract reviewers, session chairs, the presenters who are sharing their research and experience with us and to our delegates who continue to support the Congress.Please take every opportunity within the Congress to learn, familiarise yourself with new ideas and hear about the latest study results. Share your knowledge with others, build new friendships and meet old acquaintances. We also hope you find time to enjoy the wonderful city of Copenhagen.
