Background/aims: Recent evidence has shown that Alzheimer's Disease (AD) patients have reduced vestibular function relative to healthy controls. In this study, we evaluated whether patients with Mild Cognitive Impairment (MCI) also have reduced vestibular function relative to controls, and compared the level of vestibular impairment between MCI and AD patients.
Methods: Vestibular physiologic function was assessed in 77 patients (26 MCI, 51 AD) and 295 matched controls using 3 clinical vestibular tests. The association between vestibular loss and cognitive impairment was evaluated using conditional logistic regression models.
Results: Individuals with vestibular impairment had a 3 to 4-fold increased odds of being in the MCI vs. control group (p-values < 0.05). MCI patients had a level of vestibular impairment that was intermediate between controls and AD.
Conclusion: These findings suggest a dose-response relationship between vestibular loss and cognitive status, and support the hypothesis that vestibular loss contributes to cognitive decline.

Paragangliomas are slow-growing, extra-adrenal neuroendocrine tumors with rare intracranial presentation. Although benign, they can be locally aggressive tumors causing bone destruction and compression related symptoms. We report the case of a 19 years old, normotensive female who presented with headache and vertigo for the past six months.

Purpose: To investigate how adults with unilateral vestibular hypofunction and healthy controls incorporate visual and auditory cues for postural control in an abstract visual environment.
Methods: Participants stood on foam wearing the HTC Vive, observing an immersive 3-wall display of 'stars' that were either static or dynamic (moving front to back at 32 mm, 0.2 Hz) with no sound, static white noise, or moving white noise played via headphones.
