Filter by:This Doctor of Philosophy (PhD) project is part of a larger project on potentially modifiable risk factors for dementia in a life course perspective, with an overarching aim to improve prevention of dementia and thereby potentially relieve patient and caregiver distress and decrease societal load. The present PhD project will concentrate on confirming knowledge of HI as an independent risk factor for dementia and exploring potentially causative factors to explain this relationship.
This investigation is a single-centre, prospective, single-arm, post-market, non-interventional, pilot clinical investigation designed to characterize microphone sensitivity and maximum stable gain of the Cochlear Carina System.
The Auditory Nerve Test System (ANTS) is a novel device that stimulates the auditory nerve much like a cochlear implant. The purpose of this study is to demonstrate feasibility of the ANTS during translabyrinthine surgery for vestibular schwannoma resection. If the auditory nerve is kept intact, then the patients will also receive a cochlear implant at the same time potentially alleviating the morbidities caused by a vestibular schwannoma and asymmetric sensorineural hearing loss.
This is an open-labelled randomised controlled trial involving 2 groups which are Free Field voice test vs Free Field Click tests using digital hand-held devices. This study will be done at a sound-proof room in ORL clinic in Hospital Sultanah Aminah, Johor, Malaysia from January till July 2020.
The goal of the proposed project is to create an Audiobooks for Hearing Loss (HL) App - an audiobook App that has a wide array of user-selectable features designed to provide auditory training. The effects of the Audiobooks for Hearing Loss App as Auditory Training for those With CI and HA Users was measured with a 6-week trial of using the app and measuring changes in listener abilities and adherence to the program.
Although hearing aids are the most common treatment for hearing loss, and have the potential to help seniors stay active and productive, almost 50% of them who receive hearing aids rarely if ever use them, a state of affairs sometimes referred to as "the hearing aid in the drawer" syndrome. clEAR's customized auditory brain training has been shown to be effective in improving adults' abilities to recognize speech, in reducing their perceptual effort associated with listening with a hearing loss, and in increasing their confidence to engage in everyday conversations. In the proposed research, we will determine whether older adults who receive hearing aids for the first time report higher satisfaction with their new hearing aids and have longer daily use time as a result of having completed clEAR's auditory brain training program for new hearing aid users.
The study will involve the comparison of three groups with severe-profound hearing loss. Patients with a Cochlear Implant only, patients with a cochlear implant and Hearing Aid, and finally patients with two hearing aids. This will enable a comparison of standard fitting protocols against the new rationale using the same devices. Devices used for patients in all 3 groups are now available in standard of care, and can be kept afterwards should the patients wish.
One in six people in the United Kingdom and over 400 million people worldwide have disabling hearing loss. This figure will double by 2050 as predicted by the World Health Organisation. There is an urgent need to improve our knowledge regarding hearing loss, its underlying mechanisms, optimal diagnostic modalities, reliable and accurate functional and imaging biomarkers. A less-well studied condition associated with progressive hearing loss is infratentorial superficial siderosis (iSS). It results from iron deposition along the surfaces of brain structures which control hearing and balance. It is currently considered uncommon, but may well be under-recognised and therefore under-reported. Despite its severity, our current understanding of its impact on the hearing (auditory) and balance (vestibular) functions is limited, and this has an adverse impact on the treatment offered to these patients. Additionally, iSS patients have been reported to have cognitive impairment yet literature reports of cognitive assessment in iSS are few. The cognitive dysfunction may be specific to iSS or due to progressive hearing impairment or a combination of both, and further studies are required to establish this. Olfaction is also known to be affected in patients with iSS yet is rarely reported in the literature. Due to the significant morbidity and progressive nature, there is a clear need to improve our understanding of the audiovestibular dysfunction resulting from iSS. The aim of this study is to comprehensively assess audiovestibular function in iSS compared to age-related hearing loss and the controls/normative data and as a means to quantify deficits for monitoring disease progression and response to treatment, to assess the impact on the quality of life, to analyse clinically-obtained data (including imaging, cognitive and laboratory data), and correlate these with functional findings in iSS.
We recently developed a new Neuro-immersion system based on virtual reality and 3D (dimension) motion tracking. This tool makes it possible to evaluate and record the spatial localization performance of sounds and to highlight localization deficits in the three dimensions of space in deaf patients. Unfortunately, there is currently no suitable support to compensate for these localization deficits. However, the discomfort felt by the patients is clearly verbalized. Thanks to the new virtual reality system, we are now able to develop a training protocol based on spatial sound localization tasks.
Currently, the data from the literature do not evaluate the use of the middle ear implant in implanted patients in the medium term (10 years and over) but only in the short term (1-5 years). Based on the observation of the absence of these data, we considered it necessary to evaluate in the medium term the satisfaction of the patients carrying a middle ear implant and their rate of abandonment with a horizon of 10 to 20 years of apparatus.
