Pathophysiology of migraine pdf files

It is now believed that vasodilation and vasoconstriction are probably epiphenomena and that neuronal dysfunction is the possible primary driver in the pathophysiology of the disorder. Other potential causes of headache such as intracranialspinal pathology, musculoskeletal pathology. Migraine has a strong inherited component, and a large genetic study suggests the involvement of glutamate pathways in migraine pathogenesis. Migraine is a common disabling brain disorder whose pathophysiology is now being better understood. As a result, migraine is now mainly considered to be a disorder of the brain, rather than one of the vasculature or the meninges. Advances in knowledge involving genetics, epidemiology, clinical observations,pharmacology,neuroimaging,and physiology have shown that the clinical manifestations of migraine cannot be accounted for simply by changes in blood vessels. Migraine is an episodic disorder, the centerpiece of which is a severe headache generally associated with nausea andor light and sound sensitivity. This causes permanent damage to the brain, and can have longlasting physical, cognitive and emotional effects. Some people with infrequent or relatively mild attacks may prefer simply to rest while the migraine attack settles naturally,rather than take medication. The pathophysiology of migraine has emerged from a historical consideration of the humors through mid20th century distraction of the now defunct vascular theory to a clear place as a neurological disorder. Understanding the anatomy and physiology of migraine can enrich clinical practice. Identification of premonitory symptoms could enable behavioural and treatment approaches that could mitigate or prevent the headache phase of.

Migraine pathophysiologymigraine pathophysiology neuroanatomical correlates of the migraine attack vulnerability to migraine triggering migraine migraine aura migraine pain the frequency with which migraine attacks occur may vary from once in a lifetime to almost daily, an indication that the degree of migraine predisposition varies individually. It is one of the most common complaints encountered by neurologists in daytoday practice. But since migraine pathophysiology has been shown to be not solely vascular, and is now thought to be a combination of altered vascular and neural processes, migraine related vestibulopathy is easier to accept and to treat. The study of anatomy and physiology of pain producing structures in the cranium and the central nervous system modulation of the input have led to the conclusion that migraine involves alterations in the subcortical aminergic sensory modulatory systems that influence the brain widely. Understanding of migraine pathophysiology has substantially improved over the last two decades. It is important to differentiate between acute rescue, and prevention using lifestyle or drugs. Migraine epidemiology and pathophysiology vu research portal.

The current article overviews the wide array of data associated with the biological underpinnings of migraine and. Migraine pathophysiology migraine was considered to be vascular in origin for much of the 20th century 6, but today it is considered to be a disorder of the brain, with abnormalities in the vasculature occurring secondary to the primary neuronal events. But since migraine pathophysiology has been shown to be not solely vascular, and is now thought to be a combination of altered vascular and neural processes, migrainerelated vestibulopathy is easier to accept and to treat.
