Hemicrania Continua synonyms

Hemicrania continua is a strictly unilateral, persistent headache disorder that is officially classified under the International Classification of Headache Disorders (ICHD-3). While "hemicrania continua" is the universally accepted clinical term, you may encounter older or descriptive terms in medical records, such as chronic hemicrania or indomethacin-responsive headache, which highlight its defining clinical feature.

What are the common synonyms for Hemicrania Continua?

In medical literature and historical archives, Hemicrania Continua has been referred to by several names. Before its formal classification, it was often described based on its response to medication or its persistent nature. Common synonyms include:

• Chronic hemicrania


• Indomethacin-responsive hemicrania


• Continuous unilateral headache


• Chronic paroxysmal hemicrania (though this is technically a distinct, separate diagnosis)

Why does Hemicrania Continua have multiple names?

The naming of Hemicrania Continua has evolved as clinical understanding improved. Historically, physicians identified the condition by its near-total response to the medication indomethacin. As diagnostic criteria became more standardized through the International Headache Society, the term Hemicrania Continua was adopted to distinguish it from other trigeminal autonomic cephalalgias. Today, medical professionals prioritize the term Hemicrania Continua because it accurately reflects the continuous, one-sided nature of the pain, ensuring consistency across global electronic health records.
