Chronic migraine and other types of chronic daily headache
Abstract
Chronic daily headache is a common and disabling condition. It is usually due to primary headache, most often migraine, but other causes must be kept in mind. A simple approach to diagnosis is required.
Key Points
- Chronic daily headache is a common condition.
- Establishing the presence of chronic daily headache requires documentation of more than 15 days per month of prolonged headache (lasting more than four hours).
- Most cases of chronic daily headache are due to primary headache, but other causes such as structural lesions must be considered; most cases of primary headache that are troublesome are due to chronic migraine.
- Treatments for patients with chronic migraine are now available.
- Medication overuse is a common complication of headache treatment and makes successful treatment more difficult.
