Auditory Brainstem Evoked Potentials in Patients with Migraine

Abstract

SYNOPSISAuditory brainstem evoked potentials (ABEP's) using the routine 10 per second click rate, and also a 55 per second stimulus rate, were studied in 17 migraine patients between and during attacks, and in 20 normal subjects. Only in the "migraine during attack" group did the increased stimulus rate change the ABEP's. Similar changes with increased stimulus rates may be seen in situations of ischemic synaptic dysfunction. Thus, our data support a vascular pathogenesis of migraine.

Auditory brainstem response in pediatric migraine: During the attack and asymptomatic period

“…While some authors observed no abnormalities in brainstem responses [23,25,28], others have described some alterations of brainstem functions in migrainours [7,26,27,[29][30][31]. In this study, we aimed to document if any hearing changes were present in children suffering from migraine during or/and between migraine attacks.…”

“…Auditory hallucinations, tinnitus, fluctuating hearing loss, phonophobia and sudden deafness are previously reported auditory symptoms [1,5,6,[18][19][20][21][22]. Because of ABR latency variables seem to be a sensitive measures of auditory dysfunction, hearing parameters in migraine has been studied with ABR in the relevant literature [7,13,[23][24][25][26][27][28][29][30][31]. In Table 6, we summarized findings of the studies which evaluate the auditory alterations of migrainours with ABR.…”

“…By that way they modify the activity of midline structures of brainstem that causes transitory hearing differences. In few investigations, the hearing status have been evaluated during migraine attack [27][28][29][30]. Although the manifestations of migraine initiate in infancy and proceed to late life, auditory system involvement has not been studied by ABR in pediatric age group during attack period.…”

Clinical neurophysiology in childhood headache

“…Latencies have been found to be normal during the interictal phase although asymmetries have been noted [46]. In basilar migraine, on the contrary, increased latencies have been reported [47].…”

“…Changes in cognitive event-related evoked potentials (ERPs) have been demonstrated in both children and adult migraine sufferers, although studies in childhood are a still too few to generalize the data [46]. Increased amplitude of contingent negative variation (CNV) has been detected before the onset of an attack in juvenile migraine [48]; a significant increase of this potential has been reported the day before the attack.…”
