Cognitive functions in episodic vestibular disorders: Meniere's disease and vestibular migraine
BACKGROUND: Cognitive deficits have been defined in patients with bilateral and unilateral vestibular loss. OBJECTIVE: To investigate cognitive functions in patients with episodic vestibular disorders. METHODS: Nineteen patients with Meniere's disease (MD), 19 patients with vestibular migraine (VM) and 21 age and education matched healthy controls were studied. Mini Mental State Examination assessing global mental status, Reading Span Test and the Stroop Test evaluating working memory, cognitive processing, reading comprehension and attention, Trail Making Test and Benton's Judgment of Line Orientation Test investigating visual processing, visuospatial skills, processing speed were used. Beck depression and anxiety inventories were given to evaluate the emotional status. RESULTS: Cognitive test results of the MD and VM patients were not significantly different from the healthy controls (p > 0.05) as well as Beck depression scores (p = 0.14). Beck anxiety scores showed significant difference (p = 0.003). VM patients had significantly higher scores than the healthy controls (p = 0.002) on pairwise comparisons. The scores of the MD patients did not reach statistical significance (p = 0.15). CONCLUSION: Episodic vestibular disorders like MD and VM without inter-ictal vestibular deficits do not seem to be associated with cognitive impairment. Patients with VM have significantly higher anxiety scores than the healthy controls and MD patients
Vestibular test results in patients with vestibular migraine and Meniere's Disease
BackgroundVestibular migraine (VM) and Meniere's Disease (MD) are episodic vestibular disorders, sometimes difficult to differentiate from each other on clinical grounds.ObjectiveTo evaluate vestibular test results of the two groups that may help in the differential diagnosis.MethodsTwenty-two patients with VM, 21 patients with definite MD and 21 healthy volunteers (HC) were studied. Pure tone hearing thresholds (PTHT), cervical vestibular evoked myogenic potentials (cVEMPs), video head impulse test (vHIT) and functional head impulse test (fHIT) were performed.ResultsPTHT of the MD-affected ears were significantly higher than VM and HC groups (p .001 for both) when cVEMP amplitudes were lower (p = .005 for HC), (p = .006 for VM). Lateral canal vHIT gain of the MD-affected ears were lower than VM patients (p = .003) and the HC (p .001). The percentage of correctly identified optotypes (CA%) on fHIT was low for both patient groups when compared with the HC (p .001).ConclusionIn addition to hearing loss, low cVEMP amplitudes on the affected side with decreased gain on vHIT indicate disturbed saccular and lateral semicircular canal functions in MD patients differentiating them from VM. A functional deficit in gaze stabilization detected by fHIT is the only abnormality found in patients with VM
Comparison of clinical features in patients with vestibular migraine and migraine
Vestibular migraine (VM) is accepted as the most common cause of spontaneous episodic vertigo. In most patients, vestibular symptoms follow migraine headaches that begin earlier in life. The aim of this multicenter retrospective study was to find out the differences between migraine patients without any vestibular symptoms (MwoV) and VM patients and to delineate the specific clinical features associated with VM. MwoV and VM patients were compared regarding demographic features, migraine headache years, headache attack frequency, intensity, symptoms associated with headache and vertigo attacks, presence of menopause, history of motion sickness and family history of migraine. Four-hundred and forty patients with MwoV and 408 patients with VM were included in the study. Migraine with aura was more frequent in patients with MwoV (p = 0.035). Migraine headache years was longer (p 0.001) and headache intensity was higher in patients with VM (p = 0.020). Aural fullness/tinnitus was more common in patients with VM (p 0.001) when all other associated symptoms were more frequent in patients with MwoV (p 0.001) as well as attack triggers (p 0.05). Presence of menopause and motion sickness history was reported more frequently by VM patients (p 0.001). Logistic regression analysis indicated that longstanding history of migraine with severe headache attacks, aural fullness/tinnitus accompanying attacks, presence of menopause, previous motion sickness history were the differentiating clinical features of patients with VM
