Filter by:Alzheimer disease is a neurodegenerative disease. Recent studies suggest that subjects with hearing loss are more likely to develop Alzheimer's disease. Hearing loss can be consecutive to presbycusis and/or to central auditory dysfunction. Standard audiometric measures with pure tone and speech intelligibility allow the diagnosis of presbycusis. However, to demonstrate central auditory dysfunction, specific audiometric tests as noisy and/or dichotic tests, are needed. Actually, no consensus exists to investigate hearing loss in people with Alzheimer's disease; therefore hearing loss may be an early manifestation of Alzheimer's disease. Until now, investigations and clinical procedure related to the diagnosis of Alzheimer's disease ignored the hearing ability of the patient. However, the major part of care management and investigations implies the patient's communication ability with caregivers. Hearing loss may be one of the most unrecognized deficit in subjects with Alzheimer's disease. Auditory rehabilitation with hearing aids could benefit to the patient to decrease cognitive decline but this management must be investigate during longitudinal studies in order to demonstrate their efficiency and need to be compared with a placebo.
The ability to predict post-operative outcomes after implantation is important for a number of reasons, including being able to advise candidates of appropriate expectations using evidence based guidance. The approved study involves investigation of the ability to predict outcomes in the implanted ear alone and in the best-aided binaural listening conditions, examining a number of measured factors both pre-, peri- and post-operatively. The study incorporates a range of functional outcome measures through questionnaires to ascertain social, functional and demographic factors that may be predictive of outcomes. Questionnaires are also administered to determine the degree of benefit obtained after implantation for each individual, since this forms a key component of providing pre-operative counselling to candidates.
The objectives of the clinical study are to implant five deaf patients (those with Neurofibromatosis Type II, NF2) with a new two-shank auditory midbrain implant array (AMI; developed by Cochlear Limited) into the central nucleus of the inferior colliculus in order to assess the safety, reliability, consistency of placement, and performance of the AMI device. The clinical trial is being performed at Hannover Medical School in Germany in collaboration with University of Minnesota (USA) and Cochlear Limited (Australia). The clinical trial is being managed by Hannover Clinical Trial Center in Germany.
Recent studies have reported successful reduction of tinnitus after cochlear implantation (CI) in most CI users, but the mechanisms of reduction and the amount of improvement is not fully understood. Especially, the relative role of peripheral and central auditory pathways is not clearly known. This study assessed the effect of CI electrical stimulation on tinnitus in subjects with unilateral tinnitus related to a single-sided deafness (SSD), and relative contributions of peripheral and central auditory pathways in tinnitus reduction.
This feasibility study evaluates whether children with unilateral, moderate to profound sensorineural hearing loss experience an improvement in speech perception, hearing in noise, localization, and quality of life with a cochlear implant as compared to an unaided listening condition.
Twenty patients with tinnitus and a typical noise-induced hearing loss (NIHL) audiogram were included. Each subject underwent an otoscopic examination, distortion product otoacoustic emissions, tinnitus-match testing, Tinnitus Handicap Inventory (THI) and serum zinc level analyses. After 2 months of treatment with zinc, all tests were repeated.
The purpose of the study is to assess the efficacy and the safety profile of the Neuro Cochlear Implant System (CIS) in adults with severe-to-profound hearing loss.
Cortical mastoidectomy and posterior tympanotomy is a classic approach for cochlear implant. Intimate knowledge of the relevant surgical anatomy of the temporal bone and facial recess is important to safely perform the posterior tympanotomy. Anatomical variation of facial nerve such as lateral or anterior position of vertical segment of facial nerve, will render this approach challenging. In this research, investigators proposed a Radiological Classification system of the position of vertical segment of facial nerve in relation to the lateral semicircular canal to predict difficult cases with narrow facial recess.
The primary objective to this study is to describe bilateral auditory information processing in profoundly deaf patients with bilateral cochlear implants compared with normal hearing patients. Assumption used is that due to the central consequences of bilateral deafness on binaural auditory information central processing, time between activation of the two cochlear implants is a decisive factor in bilateral implantation compared to unilateral implantation
