Age-related Hearing Loss and Lexical Disorders

In France, Alzheimer's disease accounts for 70 to 80% of the causes of neurocognitive disorders, i.e. 600,000 to 800,000 patients. It is a neurodegenerative pathology that causes evolutionary cognitive dysfunction, mainly affecting memory functions. The inability to name familiar objects (lack of the word) is one of the most commonly noted symptoms at an early stage of the disease. Presbyacusis, or age-related hearing loss, is the most common sensory deficit in the elderly which is manifested socially by a progressive discomfort of verbal communication. Presbyacusis remains underdiagnosed and undertreated: 2/3 of the patients are not using hearing aid. In recent years, a link between neurocognitive disorders and hearing loss has been shown by investigating general cognition. In this study, the investigators are investigating lexical disorders.
