Purpose: Recent advances in imaging techniques have significantly enhanced the diagnosis of spontaneous intracranial hypotension (SIH). However, these developments have been reported mostly in Europe and the United States. This study aimed to evaluate the availability and utilization of diagnostic and treatment modalities for SIH in Asia, through a survey of regional headache specialists.
Methods A literature search was conducted using PubMed, and members of the Asian Regional Consortium for Headache were contacted. Participants completed a two-step survey evaluating the availability, accessibility, and frequency of SIH diagnostic and treatment methods in their countries and institutions. Descriptive statistics were used to analyze the data.
Results Twenty physicians from eight countries completed both rounds of the survey. Lumbar puncture, brain magnetic resonance imaging (MRI), and spinal MRI are widely available across Asia, but real-time imaging techniques—such as dynamic computed tomography myelography and digital subtraction myelography—that precisely localize cerebrospinal fluid leaks are less accessible. Blind or semi-targeted epidural blood patches (EBPs) are available at most centers, but are easily accessible in only about half of cases. Surgical interventions are rarely available.
Conclusion Most diagnostic methods for SIH are available in Asia, despite some regional disparities. The utilization of EBP and surgical interventions remains somewhat limited. This highlights the need for greater awareness and standardization of diagnostic methods in Asia.
Tension-type headache (TTH) is the most common type of headache, characterized by mild to moderate intensity, bilateral, with a pressing or tightening (non-pulsating) quality. Migraine and TTH can occur in the same person, and their risk factors and treatments can overlap. However, TTH receives less attention than migraine. Furthermore, despite the expanding market for migraine treatments targeting calcitonin gene-related peptide (CGRP) mechanisms, the lack of evidence regarding mechanisms related to CGRP-related mechanisms in TTH continues to be neglected. There remains a need to develop effective preventive treatments for chronic TTH, which imposes a very high burden of disease. From this perspective, this review aims to provide the latest evidence on TTH.
Purpose: Cognitive decline is a common complaint in young patients with migraine, especially those with depression. Independent of psychiatric factors such as depression, subjective cognitive decline (SCD) is associated with an elevated risk of progression to dementia. This study aimed to investigate patterns of subjective cognitive complaints between migraineurs with or without depression and non-depressed older adults.
Methods This retrospective study included 331 outpatients with SCD (293 from a headache clinic and 38 from a memory clinic). SCD was diagnosed as “yes” based on two questions about SCD. The Mini Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) were used to assess cognitive function. The SCD Questionnaire (SCD-Q) with three subdomains was analyzed to compare SCD between groups.
Results Among patients with SCD, significant differences in duration of education were found among the groups—specifically, migraineurs with depression (12.39 years) had longer education than non-depressed older adults (10.50 years) and shorter education than migraineurs without depression (14.28 years). The total MMSE and MoCA scores did not differ between migraineurs with and without depression. Regarding SCD-Q scores, migraineurs with depression showed higher scores overall and in all cognitive domains than migraineurs without depression, with no significant difference compared to non-depressed older adults.
Conclusion Although the depressed migraineurs with SCD were younger and more educated than the non-depressed older adults with SCD, both groups reported similarly high levels of SCD. Higher levels of surveillance for cognitive decline are warranted for migraineurs with depression who have SCD.
Purpose: Cluster headache (CH) is characterized by circadian rhythmicity of the attacks, and it is known to respond exceptionally well to oxygen therapy. Furthermore, obstructive sleep apnea (OSA) frequently co-occurs with CH, and both conditions may be parallel outcomes of hypothalamic dysfunction rather than being causally related. The aim of this study was to analyze the association between CH characteristics and polysomnographic factors stratified by the severity of OSA in patients diagnosed with CH and OSA.
Methods We retrospectively analyzed the data of OSA patients with CH who were enrolled in the Korean Cluster Headache Registry and underwent polysomnography due to clinical suspicion of OSA. Basic demographic data, headache-related parameters, and polysomnographic parameters were analyzed according to the severity of OSA (apnea-hypopnea index: <15 or ≥15 per hour).
Results Twelve CH patients with OSA were evaluated. The onset age of CH was higher (38.5 years vs. 19.0 years, p=0.010), and the maximal duration of cluster bouts was longer (156.5 days vs. 47.0 days, p=0.037) in the moderate-to-severe OSA group than in the mild OSA group. Unlike other polysomnographic parameters, the apnea-hypopnea index and respiratory arousal index during rapid eye movement (REM) sleep were comparable across different OSA severity levels.
Conclusion The onset age and duration of cluster bouts were associated with the severity of OSA in CH patients. Additionally, the relatively high susceptibility to hypoxia during REM sleep in patients with mild OSA implies that interventions may be potentially advantageous, even in CH patients with mild OSA.

Chronic paroxysmal hemicrania, short-lasting unilateral neuralgiform headache attacks, and hemicrania continua are rare headache disorders characterized by severe unilateral headache accompanied by ipsilateral autonomic symptoms. Accurate diagnosis and specific treatment approaches for these conditions are crucial for appropriate management. This article covers the clinical features, diagnostic criteria, and treatment strategies of each disorder, aiming to differentiate them from other major headaches and provide targeted treatment strategies to improve patient outcomes.
Headache disorders and sleep problems are common conditions with a high prevalence in the general population, and impose a considerable socio-economic burden. They show a close association with headache disorders through various relationship. The prevalence of sleep problems is elevated in individuals with headache, especially for migraine. In most headache disorders, sleep problems are accompanied by the deterioration of clinical characteristics
of headache disorders. The sharing brain structures and neurotransmitters involved in the pathogenesis of headache disorders and sleep disorders may be an explanation for the close relationship between two disorders. In this article, we briefly review the relationship of headache disorders with sleep disorders including insomnia, sleep-related breathing disorders, central disorders of hypersomnolence, circadian rhythm sleep-wake disorders,
parasomnias, and sleep related movement disorders.
Spontaneous intracranial hypotension is characterized by orthostatic headache caused by cerebrospinal fluid (CSF) leakage. However, clinical presentation of SIH is variable, and normal or high intracranial pressure in CSF study is not uncommon. Infratentorial superficial siderosis (ISS) shares similar pathomechanism with SIH, as developed after chronic CSF leakage, whilst several years of latency after SIH onset. Here, we report a 47-year-old male patient who had experienced prominent orthostatic headache twenty years before, and presented reverse-orthostatic headache in this time, accompanying with radiological features of SIH and ISS in brain magnetic resonance imaging (MRI). CSF leakage was confirmed by spinal MRI and MR myelography, and his headache was aggravated after epidural blood patch.
