Chronic Daily Headache


By definition, chronic daily headaches occur 15 or more days per month for at least 3 months. But, as the name suggests, some headache patients suffer almost daily with headaches.

Risk factors for developing CDH:

  • Previous history of frequent headaches
  • Women
  • Obesity
  • History of minor head trauma
  • Association with psychiatric disorders, such as depression and anxiety
  • Major life changes
  • Sleep changes
  • Smoking

CDH does not fit into any specific criteria, but the major primary headaches can become CDH. These include:

  • Chronic migraine (CM)
  • Chronic tension-type headache (CTTH)
  • New daily persistent headache (NDPH)
  • Hemicrania continua
  • Medication overuse headache (MOH)

Chronic migraine Patients who suffer from episodic migraine can develop chronic migraines, where the headaches occur for more than 8 days per month. The other characteristics of the pain and associated symptoms are similar to the episodic migraine.
