A Feasibility Study Evaluating the Performance of Focused Multipolar Stimulation and Sound Coding...
Hearing ImpairmentSensorineuralThe purpose of this early feasibility study is to explore several facets of hearing performance that may show improvements for alternative modes of stimulation compared to Monopolar (MP stimulation) in cochlear implant recipients. This study will iteratively evaluate different parameter sets that intend to maximize hearing performance benefits within technical requirements. This study is exploratory in nature and will achieve its objectives through ongoing review and adjustment of device parameters and fitting
Single-Sided Deafness and Asymmetric Hearing Loss
Hearing LossUnilateral2 moreThe purpose of the study is to evaluate the long-term safety and effectiveness of cochlear implantation of the approved population in adults and children with single-sided deafness and asymmetric hearing loss.
Cochlear Implantation in Children With Asymmetric Hearing Loss or Single-Sided Deafness Clinical...
Asymmetric Hearing LossSingle-sided Deafness1 moreThis is a two-phase study that compares performance growth pre-implant with current hearing aid (HA) technology versus post-implant with a cochlear implant (CI) in children with either asymmetric hearing loss (AHL) or single-sided deafness (SSD). Post-implant performance with a CI alone is expected to outperform pre-implant performance with a HA. The study also evaluates the effectiveness of bimodal hearing defined as a CI in the poor ear and a HA in the better ear for AHL or a CI in the poor ear and normal hearing in the better ear for SSD compared to pre-implant performance. The study examines factors contributing to CI outcomes.
Eyes On Lips? Speechreading Skills and Facial Expression Discrimination in Children With and Without...
Hearing ImpairmentHearing Impaired ChildrenThe goal of this clinical trial is to find out the role of background factors and gaze use in children's speechreading performance. The main questions it aims to answer are: Which background factors and eye gaze patterns are associated with the best speechreading results in hearing children and those with hearing impairment/loss? Are children's gaze patterns and facial expression discrimination associated with interpretation of emotional contents of verbal messages in speechreading? What is the efficacy of intervention that is based on the use of a speechreading application to be developed? Participants will be tested with linguistic and cognitive tests and tasks tested with a speechreading test and tasks with or without simultaneous eye-tracking about half of the participants with hearing impairment/loss will train speechreading with an application Researchers will compare the different age groups and the results of hearing children to those of children with impaired hearing to see if there are differences.
Retrieval Practice for Word Learning for Deaf and Hard of Hearing Children
Hearing LossLanguage ImpairmentThis study is designed to advance the promising yet underutilized research on retrieval practice by evaluating the effectiveness and efficiency of two key retrieval practice features (feedback and spacing). The study uses four single case adapted alternating treatments studies, each with four 5- to 8-year-old children who are deaf and hard of hearing to evaluate the effects of feedback and spacing on the efficiency of word learning and retention.
The Role of Migraine Prophylaxis Agent Topiramate in Treating Patients With Sudden Sensorineural...
Sudden DeafnessSudden Sensorineural Hearing LossMigraine and sudden sensorineural hearing loss(SSNHL) are two related disorders. A systemic steroid is usually used to treat SSNHL but the role of migraine prophylaxis medication remained unknown. Mehdi Abouzari et al. found a better improvement when combining topiramate and nortriptyline with steroids in a retrospective study. However, a prospective study with randomization is needed to elucidate the efficacy of these agents. This is a clinical study using medication approved and currently prescribed in the clinic. The included patients were those who came to the clinic and were diagnosed with SSNHL within 14 days of onset. Those patients were asked whether they agreed to participate in this clinical trial. Patients who were diagnosed with SSNHL but were later found to be other diseases such as Meniere's disease and cerebellopontine angle will be excluded from this study. The involved patients were randomized divided into two groups. Both groups received systemic steroids with/without intratympanic steroids. The experimental group receives additional oral topiramate for 6 weeks. Follow-up time is at least 3 months. This study is multi-center. Location of the study is performed at Chang gung memorial hospital Linkou branch, Taipei branch, Taoyuan branch, and New Taipei Municipal Tucheng Hospital.
Effect of Donepezil on Speech Recognition in Cochlear Implant Users
Bilateral Sensorineural Hearing LossHearing loss is a major cause of disability that affects over 48 million Americans. There are currently no medications used to treat sensorineural hearing loss. Cochlear implants can significantly restore hearing in adults with moderate to profound sensorineural hearing loss, but their utility is limited by the wide variability in hearing outcomes. Differences in cochlear implant outcomes may be explained by neuroplasticity, as neural networks must reorganize to process the new auditory information provided by the implant. The investigators predict that cholinergic enhancement with donepezil (an acetylcholinesterase inhibitor) may facilitate cortical reorganization in cochlear implant users, leading to functional improvements in speech recognition and cognition. In addition to taking donepezil, study participants will be asked to increase their daily processor use. Studies suggest that increasing daily device use can improve speech recognition, and this study will explore whether this effect can be augmented further with donepezil. In this randomized, double-blind controlled trial, the investigators aim to assess the effects of donepezil on speech recognition, cortical plasticity, and cognition. Participants will start daily treatment with either donepezil 5 mg or placebo. Participants will be followed longitudinally at 1 month and 3 months after starting the study. The findings from this study will provide important insight into the mechanisms of hearing restoration and could potentially improve hearing and cognitive outcomes for future cochlear implant users.
Auditory-Cognitive Training to Optimize Outcomes for Older CI Users
Hearing LossDeafnessThe proposed study will investigate whether an auditory brain training program can improve cochlear implant (CI) outcomes in older post-lingually deafened CI users. The study will evaluate the potential benefit of training on speech recognition performance, psychosocial and cognitive function.
A Prospective Cohort Study On Change of Cognitive Function In Aged-related Hearing Loss With Hearing...
Age-related Hearing LossHearing Loss3 moreBackground: Deafness is one of the nine potentially modifiable risk factors for dementia simulated by the Lancet dementia Prevention, intervention and Care Committee in 2017. Some studies have found that the risk factors of dementia in deafness system, with the increase of the degree of deafness, the risk of cognitive decline increases, while after long-term wear of hearing aids, the deterioration of immediate and delayed memory is less, and the possibility of cognitive decline slows down. Therefore, it is necessary for us to improve the auditory ability of patients with deafness through auditory intervention, so as to slow down its effect on dementia and reduce the incidence of dementia. At present, auditory intervention methods include hearing aid wearing and cochlear implant. However, there are few studies on cognitive function of presbycusis patients in China, and there is no research on how many years of auditory intervention can effectively slow down the incidence of dementia in presbycusis patients with MCI. Therefore, we intend to conduct a prospective cohort study on the changes of cognitive function of presbycusis under hearing aid intervention.
