The prevalence figure of nearly 90% pertains to which headache type?

• A. Cluster headache
• B. Migraine
• C. Muscle tension headache
• D. Hemicrania continua

Answer: (C)

The main idea here is recognizing which headache type is the most common in the general population. Muscle tension-type headache is by far the most prevalent, with prevalence figures often cited around 90% in many studies of people with headaches or in primary care settings. That very high figure makes it the best match for a question asking which headache type has such a widespread presence. By contrast, cluster headaches are rare, migraine affects a substantial minority but not on the order of 90%, and hemicrania continua is also quite uncommon. So the nearly 90% prevalence point specifically identifies muscle tension-type headache, the most common primary headache disorder.
