Functional Imaging in Migraine
Migraine is a common disabling condition likely to be associated with dysfunction of brain pathways involved in pain and other sensory modalities. Functional brain imaging in acute migraine has proved challenging due to the logistic problems associated with an episodic condition although it has provided us with important insights into the pathophysiology of the condition. Since the seminal obse...
متن کاملBasilar artery migraine and reversible imaging abnormalities.
We report a case of a basilar artery migraine in a 17-year-old boy with transient CT and MR abnormalities after each of two migraine episodes. A repeat MR study 6 months after the last event showed complete resolution of the lesion. Transient abnormalities on brain images similar to those shown in our case have been reported in patients with migraine and other neurologic conditions and are most...
متن کاملFunctional Neuroimaging in Migraine: Chances and Challenges.
Functional neuroimaging studies are an indispensable tool in headache research and have greatly contributed to our understanding of migraine pathophysiology. The past two decades have identified the brainstem as the target region of interest in migraine pathophysiology: Recent evidence suggests that certain areas of the central nervous system and especially the brainstem periodically change act...
متن کاملMigraine classification using magnetic resonance imaging resting-state functional connectivity data.
Background This study used machine-learning techniques to develop discriminative brain-connectivity biomarkers from resting-state functional magnetic resonance neuroimaging ( rs-fMRI) data that distinguish between individual migraine patients and healthy controls. Methods This study included 58 migraine patients (mean age = 36.3 years; SD = 11.5) and 50 healthy controls (mean age = 35.9 years; ...
متن کاملAltered functional magnetic resonance imaging resting-state connectivity in periaqueductal gray networks in migraine.
OBJECTIVE The periaqueductal gray matter (PAG), a known modulator of somatic pain transmission, shows evidence of interictal functional and structural abnormalities in migraineurs, which may contribute to hyperexcitability along spinal and trigeminal nociceptive pathways, and lead to the migraine attack. The aim of this study was to examine functional connectivity of the PAG in migraine. METH...
