The Will Erwin Headache Research Center - Cluster Headache Study

This study is gathering information from people who have cluster headache and similar conditions like paroxysmal hemicrania and SUNCT. It's an observational study, meaning researchers will collect detailed information about your condition, medical history, and other health factors over an average of five years. They want to understand more about these headaches and how they affect people, including sleep patterns, anxiety, and overall headache impact. This study is open to adults aged 18 and older who have been diagnosed with one of these specific headache types. The goal is to create a national registry to better understand these conditions and help match patients with future treatment studies.

Study design
This is an observational study aiming to enroll 1500 participants. It is not a treatment study, but rather collects information about your condition.
What's involved
Detailed evaluations and classification will be completed for each enrolled subject, including genomic and epigenomic studies, past medical history, imaging reports, and specific physical exam results. This will occur over an average of five years.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed through study completion, an average of 5 years.
