NCT07039500
Impact of Severe Obstructive Sleep Apnea-Hypopnea Syndrome on Auditory-Cognitive Processing
The goal of this observational study is to learn how severe obstructive sleep apnea-hypopnea syndrome (OSAHS) affects the brain's ability to process sounds and attention in adults aged 20-60 years. The main questions it aims to answer are: 1. Does severe OSAHS change how the brain automatically detects sound changes during wakefulness? 2. Does severe OSAHS reduce people's ability to pay attention to important sounds when awake? 3. Can brainwave tests (Electroencephalogram, EEG) detect early signs of hearing-related cognitive problems in OSAHS patients before symptoms appear? Researchers will compare two groups: * 50 adults with severe OSAHS (diagnosed by sleep tests) * 50 healthy adults matched by age and gender Participants will: * Complete hearing tests (MoCA) * Undergo a 1-night sleep test (PSG) * Wear an EEG cap for 1.5-2 hours while listening to sounds in a quiet room: * Passive task: Relax (no response needed) * Active task: Press a button when hearing rare sounds * Receive ¥75/hour compensation for their time

Hearing Aids for Veterans With Functional Hearing Difficulties
Every year, approximately 100,000 Veterans seek help at VA Audiology clinics for hearing and communication difficulties only to learn that they have normal hearing sensitivity. Unfortunately, there are very few established options to improve hearing and listening for these patients. To address this need, audiologists are increasingly prescribing hearing aids set to provide a small amount of amplification. Patients may benefit from the amplification or from modern hearing aid features such as noise reduction technology and the ability to stream sounds from a desired sound source directly to their ears thus reducing the background noise. This project will help to determine if prescribing hearing aids to patients without hearing loss is, in fact, beneficial and if so, why. It will also help to determine if some patients benefit more from hearing aids than others so that in the future, rehabilitation strategies can be better targeted toward individuals.
