Cortical spreading depression: origins and paths as inferred from the sequence of events during migraine aura.
Patients with migraine with aura often experience a variety of visual and somatosensory phenomena and disturbances of higher cortical functions. Analysis of these alterations may provide important information about the involvement of different cortical regions in cortical spreading depression (CSD). We report five cases of migraineurs who experience unusually abundant clinical phenomena during ...
متن کاملMigraine with aura during pregnancy.
CLINICAL HISTORY This is a 38-year-old G2 right-handed woman seen at 28 weeks gestation for headaches. At the age of 13, she started having migraines with aura that were frequent for several years and then became less so for many years. During her prior pregnancy 3 years ago, she had 3 migraines with aura. She had no other similar headaches until 2 months ago. She reports 9 episodes with 4 occu...
متن کاملActivation of meningeal nociceptors by cortical spreading depression: implications for migraine with aura.
Attacks of migraine with aura represent a phenomenon in which abnormal neuronal activity in the cortex produces sensory disturbances (aura) some 20-40 min before the onset of headache. The purpose of this study was to determine whether cortical spreading depression (CSD)--an event believed to underlie visual aura--can give rise to activation of nociceptors that innervate the meninges--an event ...
متن کاملMicroemboli may link spreading depression, migraine aura, and patent foramen ovale.
OBJECTIVE Patent foramen ovale and pulmonary arteriovenous shunts are associated with serious complications such as cerebral emboli, stroke, and migraine with aura. The pathophysiological mechanisms that link these conditions are unknown. We aimed to establish a mechanism linking microembolization to migraine aura in an experimental animal model. METHODS We introduced particulate or air micro...
متن کاملFamilial Hemiplegic Migraine and Spreading Depression
OBJECTIVE Familial hemiplegic migraine (FHM) is an autosomal dominantly inherited subtype of migraine with aura, characterized by transient neurological signs and symptoms. Typical hemiplegic migraine attacks start in the first or second decade of life. Some patients with FHM suffer from daily recurrent attacks since childhood. Results from extensive studies of cellular and animal models have i...
