Cluster Headaches synonyms

The primary medical term for this condition is Cluster Headache, though it is historically and clinically referred to by several synonyms, most notably Horton’s headache and histamine cephalalgia.

Historical and Clinical Synonyms

Because Cluster Headaches were historically misunderstood, they were given various names based on the perceived cause or the patient’s physical appearance during an attack. Common synonyms found in older medical texts include:

• Horton’s headache: Named after Bayard Horton, who detailed the condition in 1939.


• Histamine cephalalgia: An outdated term based on the early, now-disproven theory that histamine release was the primary cause.


• Erythroprosopalgia: Referencing the facial redness (erythema) often seen during an attack.


• Ciliary (or migrainous) neuralgia: Older descriptive terms that are no longer used in modern clinical practice.


• Suicide headache: A non-medical, colloquial term often used by patients to describe the extreme, debilitating intensity of Cluster Headaches.

Official Classification

In formal medical documentation, the International Classification of Headache Disorders (ICHD-3) uses the term Cluster Headache. In the ICD-10 and ICD-11 systems, it is classified under codes specifically related to trigeminal autonomic cephalalgias. Orphanet recognizes the condition under ORPHA:393, while the Online Mendelian Inheritance in Man (OMIM) database tracks specific genetic associations for Cluster Headaches under entry #129100. Medical professionals prefer the current nomenclature because it accurately reflects the cyclical, clustered nature of the attacks rather than an assumed underlying biological mechanism.

Why Multiple Names Exist

The variety of names for Cluster Headaches stems from the evolution of neurological understanding. Early physicians named the condition after their own observations or suspected triggers, leading to a fragmented literature. As our understanding of the trigeminal autonomic reflex has refined, the medical community has moved toward the standardized, descriptive term Cluster Headaches to ensure consistent diagnosis and communication across global health systems.
