Multicenter Study
Childhood maltreatment and migraine (part I). Prevalence and adult revictimization: a multicenter headache clinic survey.
To examine the prevalence of childhood maltreatment and adult revictimization in migraineurs and the association with sociodemographic factors, depression and anxiety. ⋯ Reports of childhood maltreatment, especially emotional abuse and neglect, are prevalent in outpatients with migraine. There is extensive overlap of maltreatment types and a high rate of revictimization in adulthood. All types of childhood abuse and neglect are strongly associated with remote and current depression and anxiety, and the relationship strengthens with an increasing number of maltreatment types.

To evaluate in a headache clinic population the relationship of childhood maltreatment on the prevalence of pain conditions comorbid with migraine. ⋯ The association of childhood maltreatment and pain was stronger in those reporting multiple pain conditions and multiple maltreatment types. This finding suggests that in migraineurs childhood maltreatment may be a risk factor for development of comorbid pain disorders.

Alcohol is a well-known trigger factor for cluster headache attacks during the active phases of the disease. The alcohol dehydrogenase (ADH) pathway, which converts alcohol to the toxic substance acetaldehyde, is responsible for most of the alcohol breakdown in the liver. Humans have 7 ADH genes, tightly clustered on chromosome 4q21-q25, that encode different ADH isoforms. The ADH4 gene encodes the class II ADH4 pi subunit, which contributes, in addition to alcohol, to the metabolization of a wide variety of substrates, including retinol, other aliphatic alcohols, hydroxysteroids, and biogenic amines. The purpose of this study was to investigate the association of genetic variants within the ADH4 gene with cluster headache susceptibility and phenotype. ⋯ Our data suggest that cluster headache is associated with the ADH4 gene or a linked locus. Additional studies are warranted to elucidate the role of this gene in the etiopathogenesis of the disease.
