Evaluation of Central Auditory Function in Migraine Patients

Abstract

igraine is an extraordinary 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 hrs. Associated with nausea, vomiting and increased sensitivity to light and sounds (Bartleson et al., 2010). Dizziness or vertigo occurs in 54.5% of patients with migraine. Clinical laboratory vestibular tests in migraine patients with or without dizziness showed a variety of abnormalities including both peripheral and central abnormalities. However, these vestibular abnormalities are more prominent in patients with migraine associated with dizziness (Ishizaki et al., 2002). Few studies were done to investigate central auditory function in migraine patients. These studies showed affection in some central auditory tests but there was need to study thoroughly and deeply the central auditory function in those patients. As migraine is commonly associated with dizziness, this study was done to investigate the central auditory processing in migraine patients with and without dizziness.
