International Headache Society

The International Headache Society is a London-based charity founded in 1981 to support professionals working with headache and facial pain disorders. It became a company limited by guarantee in 1994 and a registered charity in 1995. Professor Cristina Tassorelli, a neurology professor at the University of Pavia, serves as its current president. The society has around 1,000 ordinary members and 1,000 associated members worldwide. Its official journal, *Cephalalgia*, publishes peer-reviewed research on headache disorders. The society organises the International Headache Congress, a biennial event hosted by a national member society. This congress brings together researchers, clinicians and healthcare professionals to share advances in headache medicine. Past events have featured leading experts presenting the latest findings on migraine, cluster headaches and other conditions. The congress provides a platform for collaboration and the exchange of ideas across borders. Visitors to the society’s London office will find a professional setting dedicated to advancing headache research and care. The organisation’s work supports global efforts to improve diagnosis and treatment for patients. Its publications and events help shape international guidelines and standards. The society’s presence in London reflects its commitment to fostering connections among professionals in the field.
