Excerpt
In most studies, episodic migraineurs have an interictal habituation deficit of cortical evoked potentials to repeated monotonous stimuli. It has been found by applying almost every modality of sensory stimulation for evoked potentials (visual - VEP, auditory - AEP, somatosensory - SEP), as well as in visual evoked magnetoencephalographic (MEG) responses[
1], thus it is considered as a biomarker of the interictal status, which normalises during the migraine attacks and cannot be found in chronic migraine. A reduced habituation deficit, however, was not confirmed in migraineurs in some studies[
1], which was attributed to low reliability and repeatability[
2,
3], and to a reduced specificity to migraine pathophysiology. …
