ABSTRACT

Background: One third of older people have hearing loss, in Mexico 67% of people over 60 have it, in the United Kingdom 50%. Soon hearing loss will be one of the most frequent diseases. On the other hand, cognitive impairment affects millions of people, causing disability and dependence. It has been shown that hearing loss induces changes in brain function and structure, accelerating cognitive impairment. Objective: Describe the frequency of hearing loss in Mexican older people with and without a diagnosis of dementia and evaluate its association with cognitive impairment. Material and methods: Cases: adults over 65 with Alzheimer’s disease, unspecified dementia and dementia. Controls: healthy older people. Tests: Mini-Mental State Examination, Montreal Cognitive Assessment, tonal audiometry, Hearing Handicap Inventory for the Elderly-Screening. Analysis: descriptive, association and qualitative; identifying average, standard deviation and percentages, using Statistical Package for the Social Sciences. Statistical test: odds ratio. Results: Ten cases and 17 controls were studied. There is no statistically significant difference between age, sex, schooling, education degree or occupation. Half of the patients with cognitive impairment presented moderate to severe hearing loss. There is an association between the degree of hearing loss and the degree of cognitive impairment in the MMSE (p = 0.009) a greater hearing loss is related to a greater cognitive impairment. Conclusions: Hearing loss is considered a modifiable risk factor for cognitive impairment. In the studied population was found a high frequency of cognitive impairment.
