Abstract
Background Hearing can be impaired in many neurological conditions and can even represent a forme fruste of specific disorders. Auditory function can be measured by either subjective or objective tests. Objective tests are more useful in identifying which auditory pathway (superior or inferior) is most affected by disease. The inner ear's perilymphatic fluid communicates with the cerebrospinal fluid (CSF) via the cochlear aqueduct representing a window from which pathological changes in the contents of the CSF due to brain inflammation could, therefore, spread to and cause inflammation in the inner ear, damaging inner hair cells and leading to hearing impairment identifiable on tests of auditory function. Methods A systematic review of the literature was performed, searching for papers with case-control studies that analyzed the hearing and migraine function in patients with neuro-inflammatory, neurodegenerative disorders. With data extracted from these papers, the risk of patients with neurological distortion product otoacoustic emission (DPOAE) was then calculated. Results Patients with neurological disorders (headache, Parkinson's disease, and multiple sclerosis) had a higher risk of having peripheral auditory deficits when compared to healthy individuals. Conclusion Existing data lend credence to the hypothesis that inflammatory mediators transmitted via fluid exchange across this communication window, thereby represents a key pathobiological mechanism capable of culminating in hearing disturbances associated with neuroimmunological and neuroinflammatory disorders of the nervous system.

Grove CR, Wagner A, Yang VB, Loyd BJ, Dibble LE, Schubert MC. Greater Disability Is Associated with Worse Vestibular and Compensatory Oculomotor Functions in People Living with Multiple Sclerosis. Brain Sci 2022; 12:1519. [PMID: 36358444 PMCID: PMC9688247 DOI: 10.3390/brainsci12111519] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 11/01/2022] [Accepted: 11/06/2022] [Indexed: 08/15/2023] Open
Abstract
Globally, there are nearly three million people living with multiple sclerosis (PLW-MS). Many PLW-MS experience vertigo and have signs of vestibular dysfunction, e.g., low vestibulo-ocular reflex (VOR) gains or the presence of compensatory saccades (CSs), on video head impulse testing (vHIT). We examined whether the vestibular function and compensatory oculomotor behaviors in PLW-MS differed based on the level of MS-related disability. The VOR gain, CS frequency and latency, and gaze position error (GPE) were calculated from the individual traces obtained during six-canal vHIT for 37 PLW-MS (mean age 53.4 ± 12.4 years-old, 28 females) with vertigo and/or an imbalance. The subjects were grouped by their Expanded Disability Status Scale (EDSS) scores: PLW-min-MS (EDSS = 1.0-2.5, n = 8), PLW-mild-MS (EDSS = 3.0-4.5, n = 23), and PLW-moderate-MS (EDSS = 5.0-6.0, n = 6). The between-group differences were assessed with Kruskal-Wallis tests. The VOR gains for most of the canals were higher for PLW-min-MS compared to PLW-mild- and mod-MS, respectively. CS occurred less often in PLW-min-MS versus PLW-mild- and mod-MS, respectively. No clear trend in CS latency was found. The GPE was often lower for PLW-min-MS compared to PLW-mild- and mod-MS, respectively. Thus, our data demonstrate that worse VOR and compensatory oculomotor functions are associated with a greater MS-related disability. PLW-MS may benefit from personalized vestibular physical therapy.

Abstract
INTRODUCTION Vestibular system damage in patients with multiple sclerosis (MS) may have a central and/or peripheral origin. Subsequent vestibular impairments may contribute to dizziness, balance disorders and fatigue in this population. Vestibular rehabilitation targeting vestibular impairments may improve these symptoms. Furthermore, as a successful tool in neurological rehabilitation, immersive virtual reality (VRi) could also be implemented within a vestibular rehabilitation intervention. METHODS AND ANALYSIS This protocol describes a parallel-arm, pilot randomised controlled trial, with blinded assessments, in 30 patients with MS with vestibular impairment (Dizziness Handicap Inventory ≥16). The experimental group will receive a VRi vestibular rehabilitation intervention based on the conventional Cawthorne-Cooksey protocol; the control group will perform the conventional protocol. The duration of the intervention in both groups will be 7 weeks (20 sessions, 3 sessions/week). The primary outcomes are the feasibility and safety of the vestibular VRi intervention in patients with MS. Secondary outcome measures are dizziness symptoms, balance performance, fatigue and quality of life. Quantitative assessment will be carried out at baseline (T0), immediately after intervention (T1), and after a follow-up period of 3 and 6 months (T2 and T3). Additionally, in order to further examine the feasibility of the intervention, a qualitative assessment will be performed at T1. ETHICS AND DISSEMINATION The study was approved by the Andalusian Review Board and Ethics Committee, Virgen Macarena-Virgen del Rocio Hospitals (ID 2148-N-19, 25 March 2020). Informed consent will be collected from participants who wish to participate in the research. The results of this research will be disseminated by publication in peer-reviewed scientific journals. TRIAL REGISTRATION NUMBER NCT04497025.

Systematic Review and Discussion of Potential Pathogenesis. Front Neurol 2021; 12:707207.

Abstract
Patients affected by COVID-19 present a series of different symptoms; despite some of these are common, other less likely appear. Auditory symptoms seem to be less frequent, maybe because rarer or, alternatively, because they are underestimated during the clinical investigation. The hearing impairment might be related to the central or peripheral involvement of the auditory pathways; in particular, the likelihood of thrombosis might be one of the causes. To date, the prevalence of auditory symptoms such as sudden or progressive sensorineural hearing loss and tinnitus is unclear in COVID-19 patients. However, their presence might be an early sign of thrombosis or spread of the infection into the brain. In this systematic review of the literature we investigated the presence of auditory symptoms in COVID-19 patients and discussed their potential origin and causal relationship with SARS-CoV-2. Results showed that, despite rarely, auditory impairment can appear in patients with COVID-19 and should always be investigated for an early treatment and potential indicator of involvement of the central nervous system.

ENT-MS-12 questionnaire: A novel tool to investigate otolaryngology symptoms in patients with relapsing-remitting multiple sclerosis. Results from a pilot study. Mult Scler Relat Disord 2020; 47:102660. [PMID: 33291034 DOI: 10.1016/j.msard.2020.102660] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Revised: 11/26/2020] [Accepted: 11/28/2020] [Indexed: 11/17/2022]
Abstract
BACKGROUND Multiple sclerosis (MS) is associated with otolaryngology-related manifestations including vestibular or auditory symptoms; facial motor or sensory disorders; voice or swallowing impairment; and snoring/sleep apnea. Because these symptoms are nonspecific, their significance in MS is seldom recognized by patients with MS and their physicians; yet, presence of these symptoms may be a harbinger of impending relapse or disease progression. We developed and investigated a survey instrument, the ENT-MS-12, to standardize reporting of otolaryngology symptoms in patients with MS, correlating its scoring with disability and lesions. METHODS The ENT-MS-12 was administered to 40 patients with relapsing-remitting MS in different phases of their disease. We collected data using the Expanded Disability Status Scale (EDSS) and analyzed patient brain MRIs to evaluate the state (active or non-active) of brain lesions based on gadolinium enhancement. Odds ratios for diverse otolaryngology symptoms across the EDSS scores and brain lesions were calculated. RESULTS Higher EDSS scores were associated with auditory and vestibular symptoms (Odd Ratio (OR): 3.06; p: 0.0003); voice and swallowing symptoms (OR: 6.8; p=0.007); and snoring/sleep apnea (OR: 5.1; p=0.03). Presence of active brain lesions was also associated with auditory and vestibular symptoms (OR: 6.7); voice and swallowing symptoms (OR: 5.7); and snoring/sleep apnea (OR: 5). CONCLUSIONS The ENT-MS-12 survey instrument standardizes reporting of otolaryngology symptoms in patients with MS and documents association between symptoms and phase of disease in this series. Because ear, nose and throat (ENT)- related symptoms (i.e., sensory symptoms, such as numbness) are under-reported in MS, further investigation is warranted, as such data may improve clinical management of MS.
