ABOUT THE PROGRAMME
The IHC 2025 Scientific Programme Committee has put together a programme focused on the most up-to-date scientific discoveries covering neurology: from a new understanding of pathophysiology to new molecular targets for the development of future drugs.
In addition, the programme expands the range of medical specialties involved in the care of people with headache, meets the most current educational needs and provides relevant treatment guidelines for the whole world.
More than 150 experts from over 30 countries are participating in the Congress to share knowledge by presenting the results of their research. In addition, they will challenge participants to think beyond current constraints to provide the most advanced headache treatment possible.
The event will feature several plenary and parallel sessions, interactive workshops, meet-the-specialist sessions and symposia.
