Abstract
BackgroundMigraine is a neurological disease associated with abnormal excitability in visual, somatosensory, and motor cortex. This study aimed to verify and compare auditory processing performance in migraine patients with and without dizziness and healthy controls.ResultsSixty subjects were divided into 3 groups: control group, twenty normal healthy subjects, and study group I (twenty subjects diagnosed with migraine) and study group II (twenty subjects diagnosed with vestibular migraine). They were evaluated using the Central Auditory Processing Questionnaire for adults, tympanometry, pure tone audiometry, Psychophysical Central Auditory Tests, including Arabic Speech Intelligibility in Noise Test for adults, Arabic Dichotic Digit Test [version II], Gap in Noise Test, Duration Pattern Test, and Arabic Memory Tests. No significant difference was found between the two study groups I and II, but the significant difference was found between the study groups and the control group in all central auditory test results. Statistically significant difference was found between the control group and study groups I and II regarding all memory tests. The highest percentage of abnormality was present in temporal resolution and selective auditory attention in both study groups. There was no significant statistical correlation between the number of attacks/month and central auditory test results. There was no significant statistical correlation between the frequency of attacks in VM patients and central auditory test results.ConclusionsPatients with migraine and vestibular migraine had an inferior performance in all psychophysical central auditory tests when compared with control. Also, there was no significant difference between the 2 study groups regarding central auditory test results which may support that both migraine with and without dizziness have the same pathophysiology.
Highlights
Migraine is a neurological disease associated with abnormal excitability in visual, somatosensory, and motor cortex
The mean age of study group 1 was 34.8 years and that of study group II was 33.8 years (Table 1). This agreed with the data reported by Burstein et al [15] who reported that the mean age of migraine patients in their study was 32 years
Further analysis of the ANOVA test results using the post hoc test revealed that no significant difference was found between the two study groups 1 and 2, but the significant difference was found between the study groups and the control group in all central auditory test results *One-way ANOVA test cases of migraine with and without vertigo revealed no statistically significant difference
Summary
Migraine is a neurological disease associated with abnormal excitability in visual, somatosensory, and motor cortex. Migraine is a common disabling primary headache disorder. It is an inherited neurovascular disorder that recurs in its typical form as disabling attacks of unilateral throbbing headache, worsened by movements and routine daily activities. It lasts from 4 to 72 h associated with nausea, vomiting, and increased sensitivity to light and sounds [1]. In migraine without aura [MoA], headache is commonly unilateral and pulsating, may be associated with nausea and vomiting, and lasts for one or several days. While in migraine with aura [MA], headache is preceded by transient focal neurological symptoms such as photophobia and phonophobia. Most migraine attacks start in the brain, as suggested by the premonitory symptoms such as difficulty with speech and reading and sensory hypersensitivity that in many patients are highly predictive of the attack and by nature of some typical migraine triggers such as stress, sleep deprivation, oversleeping, hunger, and prolonged sensory stimulation [2]
