Cognition in vestibular disorders: state of the field, challenges, and priorities for the future
Vestibular disorders are prevalent and debilitating conditions of the inner ear and brain which affect balance, coordination, and the integration of multisensory inputs. A growing body of research has linked vestibular disorders to cognitive problems, most notably attention, visuospatial perception, spatial memory, and executive function. However, the mechanistic bases of these cognitive sequelae remain poorly defined, and there is a gap between our theoretical understanding of vestibular cognitive dysfunction, and how best to identify and manage this within clinical practice. This article takes stock of these shortcomings and provides recommendations and priorities for healthcare professionals who assess and treat vestibular disorders, and for researchers developing cognitive models and rehabilitation interventions. We highlight the importance of multidisciplinary collaboration for developing and evaluating clinically relevant theoretical models of vestibular cognition, to advance research and treatment
Impact and experiences of vestibular disorders and psychological distress: Qualitative findings from patients, family members and healthcare professionals.
INTRODUCTION: People with vestibular disorders frequently experience reduced quality of life and challenges with activities of daily living. Anxiety, depression and cognitive problems often co-present with vestibular disorders and can aggravate symptoms and prolong clinical recovery. We aimed to gain in-depth insights into the impact of vestibular disorders and the contribution of psychological factors by exploring multistakeholder perspectives. METHODS: Semistructured interviews were conducted between October 2021 and March 2022 with 47 participants in the United Kingdom including: 20 patients (age M = 50.45 ± 13.75; 15 females), nine family members (age M = 61.0 ± 14.10; four females), and 18 healthcare professionals. Data were analysed using framework analysis. RESULTS: Vestibular disorders impact diverse aspects of patients' lives including work, household chores, socialising, and relationships with family and friends. Being unable to engage in valued activities or fulfil social roles contributes to feelings of grief and frustration, affecting identity, confidence, and autonomy. Anxiety and low mood contribute to negative thought processes, avoidance, and social withdrawal, which can impede clinical recovery through reduced activity levels, and end engagement with treatment. Coping strategies were thought to help empower patients to self-manage their symptoms and regain a sense of control, but these require oversight from healthcare providers. CONCLUSIONS: Daily activity limitations, social participation restrictions, and psychological distress can interact to impact quality of life, sense of self, and clinical recovery amongst people with vestibular disorders. Information and resources could aid societal awareness of the impact of vestibular disorders and help patients and families feel understood. An individualised and comprehensive approach that concurrently addresses mental, physical, social, and occupational needs is likely to be beneficial. PATIENT OR PUBLIC CONTRIBUTION: Two group meetings were held at the beginning and end of the study with a patient and public involvement network formed of people with vestibular disorders and family members. These individuals commented on the study aims, interview schedule, participant recruitment practices, and interpretation of the themes identified. Two core patient members were involved at all stages of the research. These individuals contributed to the formulation of the interview schedule, development and application of the coding scheme, development and interpretation of themes, and preparation of the final manuscript

Psychological Aspects of Vestibular Disorders: A National Survey of Clinical Practice
Objective
People with vestibular disorders frequently experience psychological distress which can impede daily activities and clinical recovery. Although the need for psychological input is widely acknowledged, there are no clinical guidelines, leading to variation in care received. This study examines how psychological aspects of vestibular disorders are currently addressed highlighting any national variation.
Method
An online survey was completed by 101 UK healthcare professionals who treat vestibular disorders. The survey included open and close-ended questions covering service configurations, respondent characteristics, attitudes towards psychological aspects, and clinical practice for cognitive and mental health problems.
Results
96% of respondents thought there was a psychological component to vestibular disorders. There was a discrepancy between perceived importance of addressing psychological aspects and confidence to undertake this. Those with more years of experience felt more confident addressing psychological aspects. Mental health problems were addressed more frequently than cognitive problems. History taking and questionnaires containing one or two items about psychological distress were the most common assessment approaches. Discussing symptoms and signposting were the most frequent management approaches. Referrals for psychological support were typically to professionals within another service, via the patient’s GP. Qualitative responses highlighted the interdependence of psychological and vestibular disorders which require identification and timely intervention. Barriers to implementation included limited referral pathways and interdisciplinary expertise.
Conclusion
Clinical practice varies and relates to the confidence, experience and expertise of individual health professionals, resources, and appropriate referral pathways. Although psychological distress is frequently identified, suitable psychological treatment is not routinely offered in the UK
Noise levels within the ear and post-nasal space in neonates in intensive care
Background: Noise exposure in neonatal units has long been suspected of being a cause of hearing loss associated with such units. The noise intensity to which the neonate is exposed varies with the type of ventilatory support used. Also, the post-nasal space is an enclosed cavity that is close to the inner ear and an area of turbulent and hence potentially noisy airflow. Aim: To determine noise intensities within the ear and post-nasal space in neonates on different modes of ventilatory support using probe microphones, measures previously not undertaken. Methods: A portable instrument with a probe microphone was used for the measurements. Three groups of infants were included: (a) those receiving no respiratory support (NS); (b) those receiving conventional ventilation (CV); (c) those receiving continuous positive airways pressure (CPAP) support. Results: The mean in-the-ear noise intensities (at 1 kHz) were 41.7 dB SPL (NS), 39.5 dB SPL (CV), and 55.1 dB SPL (CPAP). The noise intensities in the post-nasal space in those receiving CPAP support were higher than in the other groups, reached mean levels of up to 102 dB SPL at some frequencies, and increased with increasing flow rates. Conclusions: The most important finding is the high noise intensities in the post-nasal space of those receiving CPAP support. Given the proximity of the post-nasal space to the inner ear, enough noise could be transmitted, especially in infants receiving the higher flow rates, to cause cochlear damage and hence hearing loss. It would therefore be wise, wherever possible, to avoid using the higher flow rates
