The vestibulo-autonomic interaction refers to the neural interplay between the vestibular and autonomic systems. In particular, the vestibular system plays an active role in adjusting blood distribution during movement and changes in posture, thereby complementing the baroreflex. This review summarizes recent clinical evidence highlighting the interaction between the vestibular and autonomic systems, including altered vestibular-evoked myogenic potentials in patients with postural orthostatic tachycardia syndrome, orthostatic hypotension, and neurodegenerative disorders. Additionally, the review introduces a model-based explanation of vestibular modulation of the autonomic system via the velocity storage mechanism. Specifically, the model demonstrates how vertigo attacks influence cardiovascular autonomic outflow by altering the estimation of gravity and inertia under pathological conditions.

Vestibular-evoked balance responses are facilitated when faced with threats to stability. However, the extent to which these sensorimotor adaptations covary with changes in emotional and autonomic state remains unclear. This study repeatedly exposed individuals to the same postural threat while vestibular-motor responses were probed using stochastic vestibular stimulation (SVS; 2-25 Hz).

Background: Motion sickness (MS) is a clinical condition that causes autonomic symptoms as a result of a mismatch in sensory inputs with unusual body and environmental movements. Although the cause of MS is not clearly established, one widely accepted theory is otolith asymmetry and canal-otolith conflict. Masseteric vestibular evoked myogenic potentials (mVEMPs) are short latency inhibitory potentials recorded from the bilateral masseter muscle in response to bilateral or unilateral galvanic/acoustic stimuli.

Background: The Vertigo Symptom Scale - short form (VSS-SF) is commonly used to measure dizziness and vertigo over the past month. This study aimed to (1) adapt the VSS-SF for the Swedish population and assess its psychometric properties, and (2) develop a modified version for measuring symptoms in the acute phase of acute vestibular syndrome (AVS).
Methods: The VSS-SF was translated into Swedish and adapted cross-culturally.

Purpose: Gamma Knife radiosurgery (GKRS) is a precise and efficacious treatment modality for vestibular schwannoma (VS) with favorable cranial nerve preservation rates. This study aims to better characterize facial nerve (FN) outcomes in VS after GKRS.
Methods: A query of six medical databases was conducted following PRISMA guidelines.
