Hearing concussion

CONTEXT: Collegiate athletes who are deaf or hard-of-hearing (D/HoH) are diagnosed with concussions at a similar rate as athletes who are hearing; however, little evidence exists on knowledge and attitudes of athletes who are D/HoH toward concussions. This study aimed to examine differences in knowledge of and attitudes toward concussions between athletes who are D/HoH and athletes who are hearing. DESIGN: Cross-sectional research design. METHODS: Of the 310 athletes who are D/HoH and 430 athletes who are hearing that were invited to participate, 90 athletes who are D/HoH, and 72 athletes who are hearing completed the survey...

The acute and long-term consequences of mild traumatic brain injury (mTBI) are far reaching. Though it may often be overlooked due to the now expansive field of research dedicated to understanding the consequences of mTBI on the brain, recent work has revealed that substantial changes in the vestibulo-auditory system can also occur due to mTBI. These changes, termed "labyrinthine" or "cochlear concussion", include hearing loss, vertigo, and tinnitus that develop after mTBI in the setting of an intact bony labyrinthine capsule (as detected on imaging)...

Mild traumatic brain injury (mTBI) is a significant health burden among military service members. Although mTBI was once considered relatively benign compared to more severe TBIs, a growing body of evidence has demonstrated the devastating neurological consequences of mTBI, including chronic post-concussion symptoms and deficits in cognition, memory, sleep, vision, and hearing. The discovery of reliable biomarkers for mTBI has been challenging due to under-reporting and heterogeneity of military-related mTBI, unpredictability of pathological changes, and delay of post-injury clinical evaluations...

PURPOSE: Traumatic Brain Injury (TBI) is a major cause of death and disability worldwide. Mounting evidence suggests that even mild TBI injuries, which comprise >75% of all TBIs, can cause chronic post-concussive neurological symptoms, especially when experienced repetitively (rTBI). The most common post-concussive symptoms include auditory dysfunction in the form of hearing loss, tinnitus, or impaired auditory processing, which can occur even in the absence of direct damage to the auditory system at the time of injury...

BACKGROUND: Previous studies based on death certificates have found professional soccer players were more likely to die with neurodegenerative diseases, including dementia. Therefore, this study aimed to investigate whether retired professional male soccer players would perform worse on cognitive tests and be more likely to self-report dementia diagnosis than general population control men. METHODS: A cross-sectional comparative study was conducted between August 2020 and October 2021 in the United Kingdom (UK)...

Persistent post-concussive syndrome (PPCS) outlines a complex array of neurocognitive and psychological symptoms that persist in patients after a concussion. A 58-year-old female presented reporting recurrent loss of consciousness, and retrograde and anterograde amnesia following multiple concussions. She also endorsed persistent nausea, balance insufficiencies, hearing loss, and cognitive impairment. In addition, this patient had high-risk sexual behavior without prior testing for sexually transmitted infections...

INTRODUCTION: Recent research on traumatic brain injury (TBI) has suggested that the mechanism of injury (i.e., whether the TBI was caused by high-level blast [HLB] vs. direct physical impact to the head) may be an important factor in injury severity, symptomology, and recovery because of differences in physiological effects of each type of injury on the brain. However, differences in self-reported symptomology resulting from HLB- vs. impact-related TBIs have not been thoroughly examined...

OBJECTIVE: To determine the longitudinal incidence of dizziness and its association with demographic factors, neurocognitive effects, functionality, and quality of life. STUDY DESIGN: Transforming Research and Clinical Knowledge in Traumatic Brain Injury (TRACK-TBI) is a prospective, longitudinal cohort study in which TBI patients were assessed at the emergency department and 2-week, 3-month, 6-month, and 12-month follow-up via telephone and/or in-person visits...

OBJECTIVE: Millions of people suffer from traumatic brain injuries every year with common sequelae, including dizziness, disequilibrium, compromised vision, and gait abnormalities. Individuals suffering a mild traumatic brain injury (mTBI) or concussion may be prescribed bed rest, but for some, symptoms may persist and require different treatment options. The aim of this mini-systematic review was to synthesize the best available evidence regarding the effectiveness of vestibular rehabilitation therapy (VRT) as a treatment option for adults with mTBIs...

PURPOSE: Auditory nerve injury is one of the most common nerve injury complications of skull base fractures. However, there is currently a lack of auxiliary examination methods for its direct diagnosis. The purpose of this study was to find a more efficient and accurate means of diagnosis for auditory nerve injury. METHODS: Through retrospectively analyzing the results of brainstem auditory evoked potential (BAEP) and high-resolution CT (HRCT) in 37 patients with hearing impairment following trauma from January 1, 2018 to July 31, 2020, the role of the two inspection methods in the diagnosis of auditory nerve injury was studied...

Sports-related injuries, such as concussion, during childhood may result in considerable morbidity, including a range of negative developmental consequences. Auditory dysfunction is generally recognized to be a possible sequela of sports-related concussion; however, few epidemiologic studies have quantified the association between hearing quality and sports-related activity in the pediatric population. The National Health and Nutrition Examination Survey for the 2015-2016 cycle was utilized to determine the association of sports activities and hearing quality...

Because traumatic brain injury (TBI)-most often caused by exposure to high-level blast (HLB)-is a leading cause of medical evacuations of deployed U.S. service members in recent conflicts, researchers seek to identify risk factors for TBI. Previous research using self-reported data has identified low-level blast (LLB) as one such risk factor and suggests an association with susceptibility to and symptoms associated with TBI. This article presents a population-based study of all branches of military service that examines the association between occupational risk for LLB and both clinically diagnosed TBIs-from concussions to severe and penetrating TBIs-and conditions commonly comorbid with concussion...

OBJECTIVE: Auditory event-related potential (ERP) correlates of pre-dementia in late-life may also be sensitive to chronic effects of mild traumatic brain injury (mTBI) in mid-life. In addition to mTBI history, other clinical factors may also influence ERP measures of brain function. This study's objective was to evaluate the relationship between mTBI history, auditory ERP metrics, and common comorbidities. METHODS: ERPs elicited during an auditory target detection task, psychological symptoms, and hearing sensitivity were collected in 152 combat-exposed veterans and service members, as part of a prospective observational cohort study...

Concerns surrounding concussions from impacts to the head necessitate research to generate new knowledge about ways to prevent them and reduce risk. In this paper, we report the relative temporal characteristics of the head resulting from neck muscle co-contraction and postural changes following a sudden force applied to the head in four different directions. In the two "prepared" conditions (i.e., co-contraction and postural), participants experienced impulsive forces to the head after hearing a warning. The warning given for the postural condition informed both the direction and timing of the impulsive force...

Based on autoethnography, this article adopts a (neuro)phenomenological lens to explore sensory experiences following a traumatic brain injury (TBI). Although focussing particularly on pain, vision, hearing, and somatic experiences connected with sleep, we also touch on how these are interwoven with other symptoms associated with TBIs. We use these experiences to enliven, and thereby enrich, clinical constructions and understandings of 'sensitivity' to light and to noise, as well as 'sleep disturbance'. We conclude with a discussion of how these sensory experiences can be understood in relation to embodied dynamics of vibration, oscillation, and (stochastic) resonance...

The use of explosive devices in war and terrorism has increased exposure to concussive blasts among both military personnel and civilians, which can cause permanent hearing and balance deficits that adversely affect survivors' quality of life. Significant knowledge gaps on the underlying etiology of blast-induced hearing loss and balance disorders remain, especially with regard to the effect of blast exposure on the vestibular system, the impact of multiple blast exposures, and long-term recovery. To address this, we investigated the effects of blast exposure on the inner ear using a mouse model in conjunction with a high-fidelity blast simulator...

INTRODUCTION: Hearing loss and insomnia emerged as preeminent sources of morbidity among military service members and veterans who served in the recent Iraq and Afghanistan conflicts. Significant threshold shift (STS), an early indicator of hearing loss, has not been studied in relation to insomnia. This study's objective was to examine the co-occurrence of STS and insomnia among U.S. military personnel with blast-related injury. MATERIALS AND METHODS: A total of 652 service members who were blast-injured during military operations in Iraq or Afghanistan between 2004 and 2012 were identified from the Blast-Related Auditory Injury Database...

Purpose College students with concussion are often ill-equipped to manage their health and learning needs, and college campuses are slow to react. We present the development of a peer mentoring program for college students with concussion: Success in College after Concussion with Effective Student Supports (SUCCESS), focusing on the process by which student needs and preferences drove development of the program for testing. Method Principles of person-centered design were used to guide program development, engaging stakeholders at each stage of development and resulting in the intervention package presented to student participants here...

Traumatic brain injury (TBI) is the leading cause of acquired long-term disability during childhood, and it may result in wide range of negative developmental consequences. Auditory dysfunction is generally recognized to be a possible sequela of pediatric TBI. Unfortunately, few contemporary studies have quantified the association between head injury and hearing loss in the pediatric population. The National Survey of Children's Health (NSCH) for the combined years 2017-2018 was used to determine the association of hearing loss with TBI...

OBJECTIVES: Recent retrospective studies report differences in auditory neurophysiology between concussed athletes and uninjured controls using the frequency-following response (FFR). Adopting a prospective design in college football players, we compared FFRs before and after a concussion and evaluated test-retest reliability in non-concussed teammates. DESIGN: Testing took place in a locker room. We analysed the FFR to the fundamental frequency (F0) (FFR-F0) of a speech stimulus, previously identified as a potential concussion biomarker...
