Cluster Headache Clinical Phenotypes: Tobacco Nonexposed (Never Smoker and No Parental Secondary Smoke Exposure as a Child) versus Tobacco‐Exposed: Results from the United States Cluster Headache Survey

Abstract: Cluster headache sufferers who were never exposed to tobacco (personal or secondary as a child) appear to present uniquely compared to the tobacco exposed subgroup. The tobacco exposed clinical phenotype appears to have a more severe syndrome based on attack frequency, cycle duration, and headache related disability. Tobacco exposure is associated with cluster headache chronification. The nonexposed subtype appears to have an earlier age of onset, higher rate of familial migraine, and less circadian periodicit… Show more

“…The clinical CH phenotype in tobacco smokers appears to be more severe, based on attack frequency, cycle duration, and headache‐related disability. Tobacco exposure is associated with a chronic state of CH . Some patients have smoked to manage pain attacks (eg, to distract from the pain) while others decreased their consumption to avoid exacerbation .…”

“…81,82 When acrolein is applied to the nasal mucosa in rats it will enhance meningeal blood flow via TRPA1 channel activation and the release of CGRP. 17 Thus, males predominated in the tobacco exposed subgroup whiles females predominated in the tobacco nonexposed subgroup and as the presentation of the subgroups differed clinically their underlying pathology may also be disparate. This may neuroanatomically link the central hypothalamic pathway alterations from cigarette toxin exposure with the more peripheral trigeminalautonomic complex pathway alterations that would be required for a tobacco/CH pathogenesis theory.…”

“…There are multiple studies suggesting a relationship between cigarette smoking and CH. 17 The tobacco exposed subgroup had a later age of onset of CH and a fixed diurnal and seasonal cycle pattern, suggesting a syndrome resulting from the delayed effects of toxin exposure over time that resulted in damage to the hypothalamus/ suprachiasmatic nucleus, the presumed generator or modulator of CH. That, in those CH patients who never smoked, the majority were exposed to cigarette smoke as a child via secondary smoke exposure by one or both parents suggests an almost requirement for tobacco exposure to develop CH in most sufferers.…”
