Chronic Daily Headache (CDH) is uncommon in Indian children compared to their adult counterpart. This is a retrospective study looking at the headache phenomenology of CDH in Indian children and adolescents. The validity of the case definitions of subtypes of chronic primary headaches mentioned in the IHS 2004 classification have been evaluated. 22 children (age range 8-15 years; M : F-16 : 6) diagnosed as having primary CDH using a modified definition seen between 2002 and 2003 have been studied. CDH has been defined as daily or near daily headaches > 15d/month for > 6 weeks. The rationale for this modified definition has been discussed. Majority of children (15/22) had a more or loss specified time of onset of regular headache spells resembling New Daily Persistent Headache (NDPH) but did not fulfil totally the diagnostic criteria of NDPH as laid down by IHS 2004. In all cases headache phenomenology included a significant vascular component. Headache phenomenology closely resembled Chronic Tension Type Headache (CTTH) in 4 patients and Chronic Migraine in 3 patients. However, in no patient in these groups, a history of evolution from the episodic forms of the diseases could be elicited. Heightened level of anxiety mostly related to academic stress and achievement was noted in the majority (19/22). Only a minority of patients (3/22) had anxiety and depression related to interpersonal relationships in the family. Medication overuse was not implicated in any patient. CDH in children in India is very much different from CDH in adults with the vast majority of patients exhibiting overlapping features of migraine and tension-type headache. There is need for a modified diagnostic criteria and terminology for chronic primary headaches in children.

Chronic daily headache (CDH) is one of the more frequently observed headache syndromes at major tertiary care centers. CDH is defined as headache occurring >15 days/month. Different mechanisms are involved in the development of CDH but what factors specifically contributing to the transformation from episodic into CDH remain largely unknown. Analgesic overuse is commonly identified as the most important factor for such transformation. Hypertension, allergy, asthma, arthritis, diabetes, obesity and hypothyroidism were associated with CDH in clinical series. The objective of this study is to identify risk factors of chronicity in patients with headache. A total of 1,483 consecutive patients were studied. We collected information on age, gender, headache type and comorbidity. Patients were divided into three diagnostic groups: migraine and tension-type headache (CTT) diagnosis were made according to ICHD-II, and CDH fulfilling the Proposal Headache Classification for Chronic Daily Headache described by Silberstein and Lipton (in Chronic daily headache including transformed migraine, chronic tension-type headache, and medication overuse, 2001). We used descriptive statistics and Chi-square test. Our data show that age, gender and headache onset were similar in the three groups. Diabetes, hypercolesterolaemia, smoke and cardiopathy prevalence did not differ in the three groups (P > 0.05). Hypertension prevalence in CDH group (16.2%) was significantly higher than in the other two groups (migraine 7.3%; CTT 6.6%; P < 0.01). There were no differences (P > 0.05) in hypertension prevalence between CDH with and without medication overuse. CDH patients (mean age 41.8 +/- 14) referred to the Headache Center later than migraine and CTT patients (mean age 37 +/- 12) (P > 0.05). According to previous studies we found that hypertension is more frequent in CDH than in migraine and CTT. Examining this result it is possible to conclude that there exists an association between CDH and hypertension, but not that a causal relationship necessarily exists. Considering the other somatic conditions we did not find any correlation. The potential role of somatic comorbidity in CDH has to be studied in further clinical trials.

Episodic Migraine and Chronic Daily Headache are common disorders affecting millions of Americans, with a significantly disproportionate affect on women. West Virginia, due to its high obesity rates and lower socioeconomic status, is likely more heavily affected by these conditions. Prevention of episodic migraine goes well beyond the limited scope of medications and includes many areas which physicians need to be knowledgeable, including lifestyle modifications, trigger avoidance, and relaxation therapies. The prevention of progression of episodic headaches to chronic headaches includes a number of options, possibly most importantly the prevention of medication overuse from either over-the-counter or prescription medications. Despite limited evidence based pharmacologic options for the prevention of headaches, there are many safe and effective mechanisms in which physicians can help their patients limit the burden of migraine and prevent the progression toward chronic daily headache.

Chronic Daily Headache is a descriptive term that includes disorders with headaches on more days than not and affects 4% of the general population. The condition has a debilitating effect on individuals and society through direct cost to healthcare and indirectly to the economy in general. To successfully manage chronic daily headache syndromes it is important to exclude secondary causes with comprehensive history and relevant investigations; identify risk factors that predict its development and recognise its sub-types to appropriately manage the condition. Chronic migraine, chronic tension-type headache, new daily persistent headache and medication overuse headache accounts for the vast majority of chronic daily headaches. The scope of this article is to review the primary headache disorders. Secondary headaches are not discussed except medication overuse headache that often accompanies primary headache disorders. The article critically reviews the literature on the current understanding of daily headache disorders focusing in particular on recent developments in the treatment of frequent headaches.
