Migraine and audiovestibular dysfunction: is there a correlation?
PURPOSE To study the audiovestibular functions in cases of migraine with or without vertigo. MATERIALS AND METHODS This was a prospective study involving 50 cases of migraine who were divided into 2 groups: patients with vertigo and those without. All patients underwent a detailed otological and neurootological examination followed by full audiological and vestibular investigation including p...
متن کاملReduced insula habituation associated with amplification of trigeminal brainstem input in migraine.
Background Impaired sensory processing in migraine can reflect diminished habituation, increased activation, or even increased gain or amplification of activity from the primary synapse in the brainstem to higher cortical/subcortical brain regions. Methods We scanned 16 episodic migraine (interictal) and 16 healthy controls (cross-sectional study), and evaluated brain response to innocuous air-...
متن کاملCortical sensory plasticity in a model of migraine with aura.
The migraine attack is characterized by alterations in sensory perception, such as photophobia or allodynia, which have in common an uncomfortable amplification of the percept. It is not known how these changes arise. We evaluated the ability of cortical spreading depression (CSD), the proposed mechanism of the migraine aura, to shape the cortical activity that underlies sensory perception. We ...
متن کاملCognitive processing of visual images in migraine populations in between headache attacks.
BACKGROUND AND OBJECTIVE People with migraine headache have altered interictal visual sensory-level processing in between headache attacks. Here we examined the extent to which these migraine abnormalities may extend into higher visual processing such as implicit evaluative analysis of visual images in between migraine events. METHODS Specifically, we asked two groups of participants--migrain...
متن کاملIncreased Functional Activation of Limbic Brain Regions during Negative Emotional Processing in Migraine
Pain is both an unpleasant sensory and emotional experience. This is highly relevant in migraine where cortical hyperexcitability in response to sensory stimuli (including pain, light, and sound) has been extensively reported. However, migraine may feature a more general enhanced response to aversive stimuli rather than being sensory-specific. To this end we used functional magnetic resonance i...
