4、1) Genetic Basis of MigraineThe aggregation of migraine within families has long beeen recognized, although consistent mendelian patterns of inheritance have not been found among the collective group of familial migraineurs. Presumably this reflects a variety of inheritance patterns, variable penetr

5、ance, and possibly multiple genes interacting with enviromental factors in the multigenic/multifactorial pattern charateristic of complex disease. Concordance rates in monozygotic twins of only 28-52 attest to the genetic component, but also predict a significant environmental contrivution.A rare su

6、btype of migraine with aura, familial hemiplegic migraine, has a straightforward autosomal dominant, highly penetrant inheritance pattern indicative of a strong genetic component. Three genetic loci for familial hemiplegic migraine have been identified:one on Chr19p13(associated with missense mutati

This theory rec

8、eived support from the efficacy of vasoconstrictive ergot alkaloids (eg,ergotamine) in aborting the acute migraine attack and vasodilators such as amyl nitrite in abolishing the migraine aura. More recent studies of regional cerebral blood flow during migraine attacks have demonstrated a reduction i

The “spreading depression” in cerebral blood flow, however, proceeds according to cytoarchitectural patterns in the cerebral cortex and does not reflect the distribution of major vascular territories.In addition, the areas

10、of decreased blood flow may remain depressde after focal neurologic symptoms have resolved and headache has begun. Later in the headache phase, blood flow increases to parts of the cortex (cingulate, auditory, and visual association areas) and the brainstem (serotonergic dorsal raphe nucleus and adr

11、energic nucleus ceruleus); treatment with effective agents (sumatriptan, ergotamine) attenuates the cortical but not brainstem changes.These date imply that vascular abnormalities in migraine may be secondary to a primary disturbance in neuronal function in the brainstem.(3) The Neuronal Theory of M

These observations suggest that neuron abnormalities could be the cause of a migraine attack.Physiologically,electrical stimulation ne

There are projections from

These various serolo nergic projections may repres

Serotonin in platelets decreases and urinary serotonin increases during theacute phase of a migraine attack. Depletion of serotonin by reserpine may precipitate migraine, The headache and othe

18、r manifestations of migraine may thus reflect a disorder of central serotonergic neurotransmission. The link between neuronal initiation and trigemino-vascular-mediated pain may be calcitonoin gene-related peptide(CGRP).which is a potent vasodilator in venous blood during migraine and decreased by serotonin antagonists(sumatriptan)Pharmacologic and other data point to the involvement of the neurotransmitter 5-HT in migraine.Approximately 40 years ago,methysergide was found to antagonize certain peripheral action of 5-HT and was introduced as the first drug capable of preventing mig
