Active clinical trials for "Presbycusis"

The purpose of this study is to compare the outcomes for two different hearing-aid delivery models. In one model, the audiologist selects and fits the hearing aid and, in the other model, the consumer does this directly.

This is a Phase 1b, prospective, randomized, double-blind, placebo-controlled, single-dose, multicenter, safety study of FX-322, administered by intratympanic injection, in adults with age-related sensorineural hearing loss.

Technological advances in hearing aids and telecommunications, including the widespread availability of telehealth (referred to in this proposal as "e-Audiology") applications, have the potential to expand both access and affordability of hearing aids for those with age-related hearing loss (ARHL). E-Audiology is used by clinicians in a variety of settings, including private practice, university clinics, and the Veterans Administration. The American Speech-Language-Hearing Association recently updated the Scope of Practice guidelines for audiology to include telehealth as "an alternative method of service delivery that en-compasses both diagnostics and intervention services.", including all aspects of hearing aid selection, fitting, and follow-up counseling and rehabilitation. However, given the paucity of evidence of comparative efficacy between office-based service delivery and e-Audiology in real-world settings, patients and relevant stakeholders are faced with a major decisional dilemma when determining which mode of service delivery would be optimal for addressing the needs, preferences, and lifestyles of those with ARHL. Thus, the purpose of this study is to determine the benefits, drawbacks, and patient satisfaction associated with e-Audiology delivery of hearing aid fitting, services, and supports for older adults with mild to moderate ARHL. We plan to use data collected in this pilot study for a future R01 submission to the NIH.

This study aims to demonstrate that the investigational drug AUT00063 is effective and safe in the treatment of age-related hearing loss.

The purpose of this study is to investigate the effectiveness of an auditory training program used at home with the subject's own hearing aids.

Hearing in noisy environments is a perceptual problem that is ubiquitous in modern industrialized societies. This particular listening context offers a particular challenge to individuals living with hearing impairment (30 million in US alone) even after treatment with hearing aids or cochlear implants. The ability of the brain to extract regularities from the environment and suppress distracting information can be improved with intensive cognitive training. The investigators will test whether the hearing in noise abilities of adults living with hearing impairment can be improved with a cognitive training paradigm.

This is a 12-months' randomized clinical trial that aims at studying the benefit of bilateral hearing aids in hearing impaired patients suffering from a slight to moderate stage Alzheimer disease. The benefit of this intervention will be studied in the cognitive, behavioural, quality of life and economic fields. 2groups are involved in this trial: Intervention group: 12 months' treatment with active hearing aids, fitted hearing impairment Control group: 6 months' treatment with placebo hearing aids, followed with 6 months' active hearing aids, fitted hearing impairment

In this study, patients with aged-related hearing loss with depression and without depression were evaluated by audiometry (pure tone audiometry and speech audiometry), cognitive function assessment (MMSE scale for simple mental state test, MoCA Scale for Montreal Cognitive Assessment), and depressive symptoms assessment (GDS-15 and HAMD), resting state EEG. The ananlysis of resting state EEG included power spectral density, traceability analysis, functional connectivity, microstate, clustering coefficient, characteristic path length, characteristic path permeability, and compatibility coefficient. EEG signals were used to explore the activation of brain regions and poor connectivity of brain regions affected by cognitive reserve dissonance on the level of brain imaging. This paper innovatively explores the influence of cognitive reserve dissonance on depressive mood in senile deafness by means of audiological assessment, cognitive function assessment, depression symptom assessment, resting state electroencephalography (EEG) and other technical means. Auditory and cognitive cortical activation, functional connectivity of brain regions, small-world attributes and microstates were analyzed in senile deafness with or without depression at the brain imaging level.

The study aims to investigate if the level of hearing aid (HA) technology has an impact on self-reported outcomes in patients with presbycusis in terms of overall IOI-HA scores, Factor 1, Factor 2 scores, SSQ scores, and the SSQ domains. The study explores if presbycusis patients report better outcomes with premium level HA technology compared to basic level HA technology. Further, the study investigates if premium level HAs provide more high-frequency gain than basic HAs using Real Ear Measurements.

Age-related hearing loss, or presbyacusis, is one of the most common chronically handicapped conditions for the elderly. Many factors including genetics, diet, diseases, drugs, socioeconomic factors and environmental variables were considered to be related to the development of presbyacusis. Evidences have shown that genetic factors play an important role on presbyacusis. However, which genes or their genotypes are associated with presbycusis remain unknown. The aim of this project was to evaluate the association between the genotype of candidate genes and presbyacusis by cross-section and case-control study. In the first stage, the investigators plan to select 700 healthy subjects older than 50 with symmetric, sensorineural hearing loss. The subjects will receive basic otologic examination, pure tone audiometry, questionnaire, and genotype analysis. Because gender and age would affect hearing loss significantly, The investigators will convert the hearing level of all subjects into a gender and age independent Z-score according to ISO 7029 standard. And, The investigators define subjects within higher 30 % of Z-score as the presbyacusis group, and subjects within lower 30% of Z-score as the control group. Finally, The investigators perform Chi square analysis to test the association between genotype of candidate genes or their combinations in both groups, and calculate the odds ratio for presbyacusis between different genotype of candidate genes. Further more, we will evaluate the effect of genotype of candidate genes, environment factors, and gene-environmental interaction on the severity of presbyacusis by multivariate logistic regression. In the second stage, The investigators wish to know the pattern of genotype and hearing level in the high risk families, according to results from the first stage, by description and case-control study. The investigators will perform t-test to evaluate the difference of Z-score in both groups. Besides, The investigators try to evaluate the effects of genotypes, environment factors, and gene-environmental interaction on hearing level in high risk families by multivariate logistic regression.
