Insights
Chronic daily headache (CDH) is a frequent headache occurring daily or almost daily without a clear pattern. This article discusses CDH and its similarities to hemicrania continua, which are often difficult to differentiate.
Area of Science:
- Neurology
- Headache Medicine
Background:
- Chronic daily headache (CDH) is characterized by frequent headache occurrence.
- CDH lacks a well-defined attack pattern and constitutes most daily headaches.
Purpose of the Study:
- To define Chronic Daily Headache (CDH).
- To discuss Hemicrania Continua and its resemblance to CDH.
- To highlight the diagnostic challenges in distinguishing CDH from Hemicrania Continua.
Main Methods:
- Literature review and clinical presentation analysis.
- Comparative analysis of diagnostic criteria for CDH and Hemicrania Continua.
Main Results:
- CDH is defined by its frequency and lack of specific attack patterns.
- Hemicrania continua shares significant clinical similarities with CDH.
- Distinguishing between CDH and Hemicrania Continua based solely on presentation is challenging.
Conclusions:
- Accurate diagnosis of chronic daily headache requires careful consideration of differential diagnoses like Hemicrania Continua.
- Further research may be needed to establish clearer diagnostic markers.
Abstract:
Chronic daily headache (CDH) refers to the daily or almost daily occurrence of headache for a prolonged period of time, with lack of a well-defined attack pattern. It constitutes the vast majority of daily headaches. Hemicrania continua, a condition that closely resembles CDH, will be discussed as part of this article because the two are difficult, if not impossible, to distinguish solely on the basis of their presentations.
