Abstract
Background: Patients with vestibular migraine (VM) describe having both vestibular and migraine symptoms. Patients with migraines have been known to have imbalance, intolerance to head movement, rotational vertigo, and positional vertigo as dizzy symptoms. Objective: To evaluate patients' cognitive function and characterize the clinical vestibular characteristics of vestibular migraine. Subjects and Methods: The 106 people in this study were split into two groups: 53 adults with VM in the cases group and 53 age and gender-matched normal adults in the control group. Every subject underwent a comprehensive history taking, a basic audiological evaluation, video nystagmography (VNG), water-based caloric irrigation, the Mini-Mental State Examination (MMSE), the Subjective Visual Vertical Test (SVV), the Cervical Vestibular Erupted Myogenic Potentials Test (c-VEMP), and the Symbol Digits Modality Test (SDMT). Result: In eighteen (34%) of the cases with upbeating tortional nystagmus in the Dix-Hallpike position (unilateral and bilateral), positional nystagmus was the most common finding during the VNG test. Nine cases (17%) of horizontal nystagmus had positional nystagmus, which was either constant in direction or changed with changes in head position. Seven instances (15%) exhibited unilateral caloric hypofunction during caloric testing. The static SVV values at the upright posture showed a statistically significant difference between the two groups (P=0.001). When VM patients were compared to their normal controls, there was a statistically significant delay in P13, N23 latency, and amplitude. In VM patients, C-VEMP anomaly represents the vestibulospinal reflex consequences of migraine. When compared to the control group, the MMSE and SDMT results indicated lower scores, which indicate cognitive impairment. Conclusions: Vestibular migraine (VM) cannot be diagnosed with a typical fixed profile in vestibular testing; instead, patients with VM exhibit spatial disorientation and dysfunction of the otolithic pathway. The duration of migraines is an unavoidable risk factor that may be linked to a decline in cognitive function.
