Headache disorders like migraine show geographic and ethnic differences between Asian and European/North American countries. In cluster headache, these differences are rarely mentioned and discussed. This article aimed to review the characteristics of cluster headache in Asian countries and compare the clinical features to those in European and North American populations.
Learn More >The analysis of particular (electroencephalographic) EEG frequency bands has revealed new insights relative to the neural dynamics that, when studying the EEG spectrum as a whole, would have remained hidden. This study is aimed at characterizing spectral resting state EEG patterns for assessing possible differences of episodic and chronic migraine during the interictal period. For that purpose, a novel methodology for analyzing specific frequencies of interest was performed.
Learn More >Headache sufferers in need of professional health care often do not utilize the care available, and factors influencing headache-specific physician consultation are not yet understood. Objectives of this study are (1) to assess self-reported headache-specific physician consultations and (2) to identify headache-related and sociodemographic predictors.

Learn More >When treating migraine patients in the current era of Coronavirus Disease 2019 (COVID-19), many institutions have moved away from face-to-face procedures like onabotulinumtoxinA injections, sometimes transitioning to the newer CGRP antibodies for migraine prevention. However, despite our best efforts to mitigate viral transmission, many of our migraine patients may eventually be exposed to SARS-CoV2. While most patients will have mild to moderate symptoms, a subset will become severely ill, with possible complications including respiratory failure and acute respiratory distress syndrome (ARDS). Given the possibility of this level of severe respiratory illness, we should consider what effect blocking calcitonin gene-related peptide (CGRP) might have on these patients.
Learn More >Subjective cognitive dysfunction is common among migraineurs. The aim of this review is to evaluate the usefulness of psychophysiology by means of the P300 component of the event-related potential in the understanding of subtle and sub-clinical changes in cognition that may occur during and between migraine episodes. Some P300 studies suggest a potential impairment of information processing, as reflected by only few findings of interictal decreased amplitude and prolonged latency, ictal augmented amplitude and prolonged latency, changes in cognitive habituation, and limited capacity to relocate attention away from painful stimuli. P300 may represent a valuable aid for clinicians to identify patients at risk of chronicization and cognitive weakening due to neurovascular complications; in this perspective a research agenda may be planned involving larger numbers of patients undergoing psychophysiological studies.
Learn More >Cluster headache is a rare form of headache associated with sleep and even speculated to be a manifestation of a sleep disorder rather than a primary headache. Cluster headache exhibits both circadian and circannual rhythmicity. While attacks often occur during sleep, the implication that cluster headaches might be involved with rapid eye movement (REM) sleep phases has neither been fully established nor refuted. The regulatory mechanisms governing sleep including hypothalamic activity and the autonomic nervous system response may play a role. Hypothalamic activation has been observed in cluster headache patients during positron emission tomography testing, but only during attacks. While sleep apnea is associated with morning headaches in general, the link between sleep-disordered respiration and cluster headache remains elusive. Hypoarousal during sleep and periods of hypoxia are associated with cluster headache, the latter likely involving inflammatory processes rather than apnea. Further study is needed, as cluster headaches represent a serious primary cephalgia that is incompletely understood.
