Background: An imbalance of the cerebrovascular response during functional activation of the brain has been postulated as a factor in the pathophysiology of migraine. The purpose of this study was to determine the transcranial doppler sonography (TDS) diagnostic value for the cerebral flow velocity changes in the interictal phase of classic migraine. Methods: This study was carried out on 46 pa...

THE CLINICAL SYNDROME of migraine is estimated to affect 23 to 29% of women and 15 to 20% of men.' This very common condition is characterized by recurrent attacks of headache associated with photophobia, anorexia, nausea, vomiting, and other autonomic disturbances and frequently by striking focal neurological manifestations. The episodes are distinctly varied in frequency, severity, and durati...

Background: Visual evoked potential (VEP) is regarded as a useful, reliable and non-invasive technique for the diagnosis of lesions in the optic pathway. This technique was used to investigate visual function in migraine. Materials and Methods: 53 migraine patients (27 migraine cases with aura and 26 common migraine cases) and 55 controls were prospectively enrolled in this study. Visual evoked...

Migraine Relief After Patent Foramen Ovale Closure: Should Vascular Risk Factor Control Be Achieved First? To the Editor: We have read with interest the article recently published in Stroke, “Shunt-associated migraine responds favorably to atrial septal repair”, by Anzola and colleagues.1 In their study, the authors focus on migraine course after transcatheter closure of patent foramen ovale (P...

BACKGROUND Trace amines, including tyramine, octopamine, and synephrine, are closely related to classic biogenic amines. They have been hypothesized to promote migraines and other types of primary headaches, but there is no direct evidence supporting this hypothesis. METHODS Using a multichannel electrochemical high-performance liquid chromatography system, the authors evaluated whether chang...

By Albert Yeung Types of Headache in Hypertensive Individuals More than 90% of people experience headache of some kind at least once in their lifetime. Many patients and physicians still believe headache to be a common symptom of hypertension. Pathophysiologically, a headache arises when the primary afferent fibers that innervate the meningeal or cerebral blood vessels are activated; most of th...
