A long-term study of rare headache disorders
Part of Brain & nervous system clinical trials.
This study is designed to learn more about a group of rare headache disorders called trigeminal autonomic cephalalgias (TACs). If you have one of these conditions, participating could help doctors better understand how they behave over time and improve care for others like you.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years old or older.
- You have been diagnosed with a specific type of headache that affects one side of the head and comes with symptoms like red or watery eyes, drooping eyelid, or a runny nose.
- You are able to sign a consent form and understand what the study involves.
- You can come back for follow-up visits and allow your health data to be collected.
- Your headaches are not caused by another medical condition (like a tumor or infection).

Other trials that look related to this one.
This study looks at people with certain severe headache disorders (cluster-type headaches or SUNCT/SUNA) or trigeminal neuralgia (sharp facial nerve pain). Researchers want to better understand these conditions and see how study testing/record review may help care.
This study looks at measurable “pain signals” (biomarkers) in people with certain headache disorders or lumbar nerve pain, and compares them with healthy people. It may help researchers better understand what drives pain and how it can be detected.
This study is a registry, meaning it collects information over time about people with headaches (including migraine, tension-type, and some dizziness-related headaches). It may help researchers better understand these conditions and plan future studies.
This trial is a registry that collects information about rare types of primary headaches in specialized Italian headache clinics. It may help researchers better understand these conditions and improve future care.
This study is a headache disorder registry that enrolls people with common, “primary” headache types such as migraine or tension headache, including some with medication-overuse headaches. It collects information to better understand these conditions and who they affect.
This trial is a registry study that tracks people with various headache disorders over time. It aims to learn more about how headaches affect patients and to improve future care.
