Age-related Hearing Loss and Lexical Disorders

Study Overview
=================
Brief Summary
-----------------
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.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Link Between Lack of Word and Presbycusis | The Batterie Informatisée du Manque du Mot (BIMM) is a computerized assessment instrument for denominational disorders. It provides information on level of lexical impairment, type of error (phonological, semantic, visual perceptual) and response time. It comprises two tests: denomination of nouns (42 items, score range from 0 to 42) and of verbs (28 items, score range from 0 to 28). The results are presented in a report including scores, description of qualitative errors, and results per item. A global score of less than 40 indicates a lack of words. The score range is between 0 and 70. The hearing questionnaire consists in 14 questions about concrete situations and a direct question about what the patient thinks of his hearing. Answers are quoted 0, 2 or 4 points. An overall score greater than 14 indicates presbycusis. | at inclusion |
