Insights
Chronic daily headache (CDH) affects 4% of adults, causing significant suffering and economic costs. Accurate diagnosis of specific CDH subtypes, like chronic migraine, is crucial for effective management.
Area of Science:
- Neurology
- Headache Medicine
Background:
- Chronic daily headache (CDH) affects approximately 4% of adults.
- CDH significantly impacts quality of life and incurs substantial societal economic costs.
- While often chronic migraine or tension-type headache, CDH can also stem from secondary causes.
Purpose of the Study:
- To review the diagnosis and management of primary CDH entities.
- To emphasize the importance of differentiating specific CDH subtypes for targeted treatment.
- To highlight the role of medication overuse headache in the context of primary CDH.
Main Methods:
- Review of literature on diagnosis and management of CDH subtypes.
- Emphasis on differentiating primary and secondary causes of daily headaches.
- Discussion of chronic migraine, chronic tension-type headache, new daily persistent headache, and hemicrania continua.
Main Results:
- Accurate diagnosis of specific CDH subtypes is essential for effective treatment.
- Ruling out secondary headaches is a critical first step in CDH management.
- Medication overuse headache frequently co-exists with primary CDH.
Conclusions:
- Proper investigation is necessary to exclude secondary headaches presenting as CDH.
- Specific diagnosis of primary CDH subtypes (e.g., chronic migraine) guides appropriate therapeutic strategies.
- Understanding the interplay between primary CDH and medication overuse headache is vital for comprehensive patient care.
Abstract:
Chronic daily headache (CDH) is a descriptive term that encompasses multiple headache diagnoses and affects approximately 4% of the general adult population. Chronic daily headache results in significant pain and suffering with substantial impact on quality of life, and enormous economic costs to society. Although most patients with primary CDH suffer from chronic migraine or chronic tension-type headache, other primary and secondary headache disorders can also manifest as a CDH syndrome. For CDH management to succeed, secondary headaches need to be ruled out with proper investigations when judged necessary. If the diagnosis of primary CDH is established, diagnosis of the specific CDH subtype is imperative to institute appropriate treatment. The diagnosis and management of distinct CDH entities, chronic migraine, chronic tension-type headache, new daily persistent headache, and hemicrania continua, are the primary forms of CDH and the emphasis of this review. Although, strictly speaking, medication overuse headache is a secondary form of CDH, it is also highlighted in this review given its frequent association with primary CDH.
