“…A previous multicenter, cross-sectional registry study found that a diagnosis of probable primary headache disorder, based on ICHD-3β, was given to 21.3% of first-visit patients due to incomplete or atypical presentations of the headaches. The proportions of probable primary headache disorders differed among the subtypes as follows: migraines (16.1%), tension-type headaches (33%), TACs (40.9%), and other primary headache disorders (14%) ( 12 ). Although a difference is noticeable, it is difficult to make a direct comparison because the number of patients included and the method of investigation used differed.…”

“…According to two population-based surveys, the most common unmet criterion preventing a definitive migraine diagnosis was headache duration (61.1 and 82.0%, respectively); a separate multicenter study identified the number of attacks (41.9%) and associated symptoms (33%) as the most common unmet symptoms ( 6 , 10 , 12 ). Number of attacks (65.3%) was also the most commonly unmet criterion among cases of probable tension-type headache ( 12 ). In terms of unmet criteria, the prevalence of diagnostic stability was lower in subgroups lacking data on time-based criteria, such as number of attacks or total headache period.…”

“…However, epidemiological data assessing probable diagnoses of CH or trigeminal autonomic cephalalgia (TAC) remain limited. Previously, a study found the prevalence of suspected CH in 32 of 1,145 (2.7%) cases included in a community-based survey, whereas the prevalence of probable TAC among all TAC cases was 40.9% in a multicenter study of first-visit headache outpatients at neurology clinics ( 12 , 13 ). Furthermore, neither the clinical characteristics of probable CH nor its effects on the quality of life of sufferers have been reported.…”

Background: Epidemiological data of probable cluster headaches (CH) are scarce in the relevant literature. Here, we sought to assess the prevalence and clinical characteristics of probable CH in comparison with definite CH.Methods: Data used in this study were obtained from the Korean Cluster Headache Registry (KCHR), a prospective, cross-sectional, multicenter headache registry that collected data from consecutive patients diagnosed with CH.Results: In total, 159 patients were enrolled in this study; 20 (12.6%) were diagnosed with probable CH. The most common unfulfilled criterion in patients with probable CH was the duration of attack, which was found in 40% of patients with probable CH. Among clinical characteristics, the number of autonomic symptoms tended to be lower in probable CH than in definite CH (1.7 ± 1.2 vs. 2.4 ± 1.5, p = 0.051) and conjunctival injection and lacrimation showed an increased odds ratio (OR) [OR = 3.03; 95% confidence interval (CI): 1.03–8.33] in definite CH. The groups did not differ with regard to baseline demographic characteristics, disability, impact on life, or treatment response.Conclusions: Probable CH is relatively common among CH disorders, with a clinical impact similar to that of definite CH.

Background and PurposeChronic daily headache (CDH) is defined as a headache disorder in which headaches occur on a daily or near-daily basis (at least 15 days/month) for more than 3 months. Chronic migraine (CM) and medication overuse headache (MOH) are very disabling headaches that remain underdiagnosed. The aim of this study was to establish the frequency of CDH and its various subtypes, and examine the associations with MOH among first-visit headache patients presenting at neurology outpatient clinics in Korea.MethodsEleven neurologists enrolled first-visit patients with complaints of headaches into outpatient clinics for further assessment. Headache disorders were classified according to the International Classification of Headache Disorder (third edition beta version) by each investigator.ResultsPrimary CDH was present in 248 (15.2%) of the 1,627 included patients, comprising CM (143, 8.8%), chronic tension-type headache (CTTH) (98, 6%), and definite new daily persistent headache (NDPH) (7, 0.4%). MOH was associated with headache in 81 patients (5%). The association with MOH was stronger among CM patients (34.5%) than patients with CTTH (13.3%) or NDPH (14.3%) (p=0.001). The frequency of CDH did not differ between secondary and tertiary referral hospitals.ConclusionsThe frequencies of CDH and MOH diagnoses were 15.2% and 5%, respectively in first-visit headache patients presented at secondary or tertiary referral hospitals in Korea. CM was the most common subtype of CDH and was most frequently associated with MOH.

“…This was a substudy of the headache registry using ICHD-3β for the first-visit patients (HEREIN) study using prospectively collected multicenter data obtained from consecutive first-visit headache outpatients in the headache clinics of 11 hospitals in Korea between August 2014 and February 2015 [ 11 – 13 ]. The study design of the HEREIN study was proposed and reviewed at regular educational meeting of the Korean Headache Society after a request regarding the application of ICHD-3β; study members were board-certified neurologists with special interests in the headache field.…”

BackgroundA “Probable headache disorder” is diagnosed when a patient’s headache fulfills all but one criterion of a headache disorder in the 3rd beta edition of the International Classification of Headache Disorder (ICHD-3β). We investigated diagnostic changes in probable headache disorders in first-visit patients after at least 3 months of follow-up.MethodsThis was a longitudinal study using a prospective headache registry from nine headache clinics of referral hospitals. The diagnostic change of probable headache disorders at baseline was assessed at least 3 months after the initial visit using ICHD-3β.ResultsOf 216 patients with probable headache disorders at baseline, the initial probable diagnosis remained unchanged for 162 (75.0 %) patients, while it progressed to a definite diagnosis within the same headache subtype for 45 (20.8 %) by fulfilling the criteria during a median follow-up period of 6.5 months. Significant difference on the proportions of constant diagnosis was not found between headache subtypes (P < 0.935): 75.9 % for probable migraine, 73.7 % for probable tension-type headache (TTH), and 76.0 % for probable other primary headache disorders (OPHD). Among patients with headache recurrence, the proportion of constant diagnosis was higher for probable migraine than for probable TTH plus probable OPHD (59.2 vs. 23.1 %; P < 0.001). The proportions of constant diagnosis did not significantly differ by follow-up duration (>3 and ≤ 6 months vs. > 6 and ≤ 10 months) in probable migraine, probable TTH, and probable OPHD, respectively.ConclusionsIn this study, a probable headache diagnosis, based on ICHD-3β, remained in approximately three-quarters of the outpatients; however, diagnostic stability could differ by headache recurrence and subtype. Probable headache management might have to consider these differences.

Prevalence and Features of a Probable Diagnosis in First‐Visit Headache Patients Based on the Criteria of the Third Beta Edition of the International Classification of Headache Disorders: A Prospective, Cross‐Sectional Multicenter Study

Abstract: A probable diagnosis was given to 21.3% of the first-visit PHD patients due to incomplete or atypical presentations of the headaches. The incorporation of a probable diagnosis into the ICHD-3β may be useful for reducing the diagnoses of unspecified headaches.
