The origin, density, and distribution of sympathetic nerve fibers in the supratentorial dura mater of the rat were examined in detail in the current study by using wheat germ agglutinin horseradish peroxidase (WGA-HRP) retrograde tracing procedures, glyoxylic acid-induced fluorescence, and dopamine beta-hydroxylase (DBH) immunocytochemical staining of dural whole mount preparations. Application of WGA-HRP to the superior sagittal sinus and adjacent areas of the supratentorial dura mater labeled numerous neurons in each of the left and right superior cervical ganglia. Glyoxylic acid and DBH immunocytochemical staining of fixed dural whole mount preparations revealed prominent plexuses of sympathetic nerves about the middle meningeal artery and its branches, about the superior sagittal and transverse sinuses, and "free" within the dura mater, i.e., apparently unassociated with any vasculature. Significantly, in all of these areas, the density of sympathetic innervation revealed in this study was considerably greater than that previously demonstrated by other workers. An impressive population of mast cells also was observed within the dura mater of the glyoxylic acid-treated preparations. The majority of these cells were perivascular; however, a significant number were also present within the dura unrelated to the vasculature, and occasional cells were seen in close apposition to fluorescent sympathetic nerve fibers. Taken together, the identification of a robust sympathetic plexus and prominent mast cell population associated with a dura mater that also receives significant sensory projections from the trigeminal system raises interest regarding the functional interactions of these elements. These observations warrant further consideration regarding their role in the pathogenesis of vascular headache and head pain.

Migraine has been considered a manifestation of sympathetic dysfunction. Serum dopamine beta-hydroxylase (D beta H) has been shown to be an index of peripheral sympathetic activity by some workers and there are two reports of elevated activity of the enzyme during the migraine headache as well as in the headache-free interval. We studied the enzyme in seven women complaining of regular attacks of menstrual migraine and eleven controls during the mid-follicular (days 10 +/- 2) and premenstrual (days 28 +/- 2) phases of the menstrual cycle. Although levels were on average 26% and 10% higher respectively than in control subjects, the difference failed to reach statistical significance because of the large normal range for enzyme activity. However, the premenstrual results were significantly lower (p less than 0.001) than the mid-follicular measurements in the migraine group, little difference being found in controls. This finding, and the effects of successful therapy with anovulatory doses of oestradiol implants in not only significantly lowering serum D beta H but also significantly reducing the difference in enzymic activity between the early and late phases of the menstrual cycle, suggest that if this enzyme is an index of sympathetic activity, it is excessive fluctuations of the sympathetic nervous system that may be relevant in menstrual migraine.

Plasma levels of adrenaline, noradrenaline, cAMP, free fatty acids and serum DBH, were estimated in a group of ten migrainous patients before, during and after a migraine attack. All parameters, apart from adrenaline, showed a statistically significant elevation during the headache period. As the blood concentration of the above substances taken in combination is the most reliable index of sympathetic activity available at present, these findings indicate that there is considerable sympathetic dysfunction during the migraine attack.

Migraine is a debilitating neurological disorder characterized by recurrent attacks of severe headache. The disorder is highly prevalent, affecting approximately 12% of Caucasian populations. It is well known that migraine has a strong genetic component, although the type and number of genes involved is not yet clear. However, the calcium channel gene, CACNA1A, on chromosome 19 contains mutations responsible for familial hemiplegic migraine, a rare and severe subtype of migraine. There is also evidence to suggest that serotonin- and dopamine-related genes may be involved in the pathogenesis of migraine. This study employed a linkage and association approach to investigate neurotransmitter-related migraine candidate genes. Polymorphisms within the dopamine beta-hydroxylase (DBH) gene, serotonin transporter gene (SERT), and dopamine receptor gene (DRD2) were tested in 177 unrelated Caucasian migraineurs and 182 control individuals. In addition, an independent sample of 82 families affected with migraine was examined. Unrelated case-control association analysis of a DBH intragenic dinucleotide polymorphism indicated altered allelic distribution between migraine and control groups (chi2 = 16.53, P=0.019). Furthermore, the transmission/disequilibrium test, which was implemented on the family data, also indicated distortion of allele transmission for the same DBH marker (chi2 = 4.44, P=0.035). Together, these results provide evidence for allelic association of the DBH gene with typical migraine susceptibility (Fisher's combined P value =0.006) and indicate that further research into the role of the DBH gene in the etiology of migraine is warranted.
