  • What is Cluster Headache?
    Cluster headache, nicknamed "suicide headache", is a neurological disease that involves, as its most prominent feature, an immense degree of pain. "Cluster" refers to the tendency of these headaches to occur periodically, with active periods interrupted by spontaneous remissions. The cause of the disease is currently unknown. We could go into great detail, but maybe it's better if you hear from real patients.
  • What are Shadows?
    Although not part of the official diagnostic criteria, many people living with cluster headache describe a low-level persistent headache that can be a precursor to full-blown cluster headache attacks. We call these "shadows." Read patient descriptions of this unique symptom.

  • Finding the Right Doctor
    Cluster headache is rare, but not as rare as many doctors think.  It is also more common in men than women. Some female patients have reported decades of improper medical treatment due to an inaccurate diagnosis simply because the doctor believed it was impossible for a woman to have cluster headache. The best way to minimize the risk of misdiagnosis is to seek help from a specially-trained neurologist who is board-certified in headache medicine.  There are a few ways to find a good specialist.
  • Getting the Right Diagnosis
    For cluster headache, the average time from onset of symtpoms to accurate diagnosis is 8 years. Unbelieveable, right? Whatever the reason, it is important to get the right diagnosis as quickly as possible. Given the hundreds of possible headache disorders, that can be challenging, even for the most skilled doctor. Take a look at these common headache diagnoses to understand the complexity.
