The Migraine Trust is dedicated to helping people affected by migraine. We are the only UK migraine charity providing information and support, campaigning for awareness and change, and funding and promoting research.

One in seven people in the UK live with migraine, and this complex and debilitating neurological disorder significantly affects their lives. We have been leading and bringing the migraine community together to change this since 1965.

Every year over two million people visit our website and thousands contact our helplines for information and support on all aspects of migraine and for help in managing it at work, in education, and in accessing healthcare.

We campaign for increased awareness and understanding of migraine, and national policy change to improve the lives of people who get it.
