Active clinical trials for "Deafness"

The rationale is to determine (in individuals with limited perceived bimodal benefit) whether the CROS device may be a better solution for obtaining two-sided input. If yes, this study would be practice-changing.

The world population has been growing and aging dramatically, with a rising prevalence of dementia. Worldwide, around 50 million people have dementia, with 10 million new cases added every year. Despite the epidemic scale of dementia, until now no cure or disease-modifying therapy has been identified. Therefore, the World Health Organization (WHO) has recognized dementia as a public health priority. Several large studies have demonstrated that hearing impairment is associated with a greater risk of cognitive impairment. Hearing rehabilitation could potentially provide a disease-modifying therapy to delay cognitive decline. Although auditory behavioral research has not yet revealed a reliable indicator of early cognitive impairment, cortical-evoked auditory potentials (CAEP) have shown promising evidence as a non-invasive way to identify early-stage cognitive impairment. The peripheral vestibular apparatus is located in the inner ear and codes rotation and translation of the head to preserve a stable view. Increasing evidence suggests that bilateral vestibular function loss, also known as bilateral vestibulopathy (BVP), leads to hippocampal atrophy and reduced spatial cognitive skills, as well as structural and functional alterations in parieto-insular and parieto-temporal regions. Many studies have demonstrated that vestibular function declines with age. Vestibular dysfunction can be linked to reduced topographical orientation and memory and has been suggested as a risk factor to AD, due to increased risk of falling and deficits in activities of daily life (ADL). Our first aim is to study the effect of SNHL and vestibular decline on CAEP, spatial and non-spatial cognitive functioning and trajectories in cognitively healthy older subjects, as well as patients with mild cognitive impairment (MCI) and AD. Our second aim is to study if MRI brain volume changes can be observed in the hippocampus, entorhinal cortex, and auditory and vestibular key regions in these populations and correlate with CAEP and cognitive functioning. The expected outcome is important to society because it will provide data from a cognitive assessment protocol adapted for a potentially hearing-impaired population, objective outcome measures (incl. CAEP and MRI brain volume changes) to identify older subjects with SNHL and BVP at risk for cognitive decline, and will support screening and interventional studies to assess the impact of rehabilitation on slowing down cognitive decline.

The deaf children showed deficits in speech processing and temporality. They badly apprehend temporal concepts and perceptions of deficit so the acoustic phenomena marking the time course linguistically. Their prediction capabilities and anticipation multisensory events are thereby affected, thus impacting their ability to adapt to multiple and complex interaction possibilities that arise during a conversation.The project aim it is to measure the impact of a musical rhythmic stimulation of neuronal activity and the temporal prediction capabilities of older deaf children 5 to 8 years and its impact on their language skills in a conversational task. A matched control group of age will be examined for each of the proposed tasks. We first measure the capacity to anticipate a situation of language interaction. For this purpose, we will use an alternate naming paradigm with a virtual partner, already developed and tested in children with normal hearing. This paradigm approaches the conversational situation while allowing control of the time parameter of speech (speed of trade) and by controlling the bias (temporal) inherent linguistic programming difficulties of children in a spontaneous conversation situations . Then we will couple behavioral measurements with measurements of eye movements and the electroencephalogram (EEG) in deaf children. For this, we use a dialog observation task already developed for normal hearing children. This task will allow us firstly to analyze the anticipation level of speaking turns by analyzing eye movements (which "precedes" the speaker). Secondly, it will allow us to study the effects of manipulation of the acoustic parameters of auditory evoked potentials (AEP) and the oscillatory activity of the motor system (EEG, mu rhythm and beta). The audiomoteur coupling would seem to be the key point of anticipatory processes and convergence in conversational interaction will also be studied using cortico-cortical coherence techniques to assess the dynamics of connectivity between remote networks (system here auditory and motor system).

The majority of studies about bimodal hearing advantages have been conducted on adults but scant relevant studies into pediatric users, therefore more comparative studies are required to compare the effect of bimodal stimulation to unilateral cochlear implant use in children with severe to profound sensori-neural hearing loss .

Hearing impairment in older adults is becoming a common health problem as the population ages. The impact of hearing impairment in older adults includes not only physical function and cognitive performance, but also depression, loneliness and social isolation, as well as having a negative impact on quality of life and financial status. Therefore, an audiological rehabilitation program intervention is recommended. The purposes of this study are to examine the effects of an audiological rehabilitation program (Hear-Talk-Activity audiological rehabilitation program) intervention on communication abilities, depression, loneliness and quality of life outcomes in older adults with hearing impairment. The single-blind, randomized control trial will include older adults aged 65 years or older with hearing impairment and aid user. Participants will be randomized to either intervention groups or control groups.

This study aims to investigate the effect of Hericium Erinaceus on clinical patients with hearing impairment and possible mechanisms. Subjects with hearing impairment will be enrolled and randomly divided into experimental or control group supplemented with Hericium Erinaceus (430 mg/kg/day) or placebo, respectively for eight months. Basic characteristics will be evaluated at baseline by questionnaire. The hearing, liver and kidney functions, and neurotrophic factors will be examined at baseline, 4th month and 8th month.

The purpose of this study is to test the effectiveness of a community health worker intervention to expand access to hearing health care among older adults facing health disparities.

The following research questions will be investigated: What is the knowledge of medical interventions for moderate to severe hearing loss and what is the knowledge of the reimbursement criteria for hearing implants of otorhinolaryngologists in a secondary setting in Brabant. This will be evaluated by means of a specific questionnaire that will be systematically gone over with the participants during an interview in the first and third phase. In a second phase, the investigators will investigate how the knowledge of medical interventions for moderate to severe hearing loss and the knowledge of the reimbursement criteria for hearing implants of otorhinolaryngologists in a secondary setting in Brabant can be increased by training the otorhinolaryngologists in a secondary setting in Brabant. In the third phase, the investigators will evaluate the knowledge of hearing implant interventions and reimbursement criteria among otorhinolaryngologists in a secondary setting.

To test the effectiveness of body-worn, digital hearing aids, model 02 which is developed by the National Electronics and Computer Technology Center, Thailand.

In this study, the investigators will evaluate whether auditory training with speech-related acoustic features in psychophysical testing will help CI subjects improve speech recognition. The primary endpoint is the speech recognition measures.
