Cluster Headache Awareness Day 2020 - 21 March

Download our Media Kit

IHS is running a global campaign for the awareness of Cluster Headache and we will focus on the diagnosis, treatments and cause of this debilitating condition.

We hope this advocacy campaign brings together the global community to disseminate cluster headache diagnosis and prevention strategies to clinicians, researchers and patients in the hope of achieving better patient outcomes and contributing to the IHS mission statement of working toward headache relief worldwide.

We invite you to participate in this campaign and share the facts about Cluster Headache through our social media accounts. To join the conversation, use #ClusterHeadacheDay2020 and #ClusterDay20 on Twitter, Facebook, Instagram and LinkedIn. Use our media kit, including logos, to elevate the conversation of Cluster Headache awareness and help spread the word about this important advocacy campaign.

As headache professionals, it is our duty to communicate diagnostic and preventive methods to our colleagues, patients and the general public in order to ensure proper care at the proper time and hopefully avoid or, at the very least, lessen the impact it has on daily functioning and quality of life.

Throughout this year, IHS will be offering a variety of materials dedicated to communicating diagnostic and treatment methods geared toward clinicians, researchers and those living with Cluster Headache. We plan an exciting lineup of fact sheets, webinars and other communications to share with you, and we encourage you to share the information widely.

Together, we can provide the latest research, clinical practices, treatments and self-management techniques to work toward a world with better understanding of Cluster Headache.
