OBJECTIVE To determine whether hearing loss is associated with incident all-cause dementia and Alzheimer disease (AD). [] Key MethodDESIGN Prospective study of 639 individuals who underwent audiometric testing and were dementia free in 1990 to 1994. Hearing loss was defined by a pure-tone average of hearing thresholds at 0.5, 1, 2, and 4 kHz in the better-hearing ear (normal, <25 dB [n = 455]; mild loss, 25-40 dB [n = 125]; moderate loss, 41-70 dB [n = 53]; and severe loss, >70 dB [n = 6]).

Background Age-related peripheral hearing impairment (HI) is prevalent, treatable, and may be a risk factor for dementia in older adults. In prospective analysis, we quantified the association of HI
Hearing Loss and Risk of Mild Cognitive Impairment and Dementia: Findings from the Singapore Longitudinal Ageing Study
TLDR
Hearing loss is independently associated with prevalent dementia and incident mild cognitive impairment, dementia and MCI or dementia (all cases).
Relationship of Hearing Loss and Dementia: A Prospective, Population-Based Study
TLDR
Elderly individuals with HL have an increased rate of developing dementia and more rapid decline on 3MS-R scores than their nonhearing impaired counterparts, suggesting that hearing impairment may be a marker for cognitive dysfunction in adults age 65 years and older.
Longitudinal Changes in Hearing and Visual Impairments and Risk of Dementia in Older Adults in the United States
TLDR
Findings suggest that assessment of both hearing and vision may help to identify older adults who are at high risk of developing dementia.
The Impact of Hearing Loss on Clinical Dementia and Preclinical Cognitive Impairment in Later Life.
TLDR
A significant correlation between different types of hearing loss and cognitive impairment was revealed and Noise-induced hearing loss is especially important because it occurs earlier than other types of Hearing loss and has large effects on cognitive impairment.
Neuropathological Findings of Dementia Associated With Subjective Hearing Loss.
TLDR
Subjective hearing loss was not found to be associated with significantly different dementia neuropathology, which counters hypotheses on hearing loss causing permanent neurodegeneration and cognitive decline, suggesting a potential neuroprotective effect of hearing aids.
Hearing loss and cognitive decline in older adults.
TLDR
Hearing loss is independently associated with accelerated cognitive decline and incident cognitive impairment in community-dwelling older adults and the mechanistic basis of this association is and whether hearing rehabilitative interventions could affect cognitive decline is investigated.
Age-Related Hearing Loss, Neuropsychological Performance, and Incident Dementia in Older Adults.
TLDR
The observed association between Untreated HL and lower cognitive ability that improved when hearing aids were worn may reflect an inability to hear the test instructions.
Hearing Impairment and Cognition in an Aging World
TLDR
Current research on the association between hearing loss and dementia is summarized and potential casual mechanisms behind the association are reviewed, to emphasize key areas of research which might best inform the investigation of this potential casual association.

Relationship of hearing impairment to dementia and cognitive dysfunction in older adults.
TLDR
An association between hearing impairment and dementia is demonstrated and support is lent to the hypothesis that hearing impairment contributes to cognitive dysfunction in older adults.
Hearing Impairment and Cognitive Decline in Senile Dementia of the Alzheimer's Type
TLDR
Data from a longitudinal study suggest that hearing impairment may be a prognostic indicator for subsequent cognitive dysfunction in senile dementia of the Alzheimer's type (SDAT).
Hearing Impairment as a Predictor of Cognitive Decline in Dementia
TLDR
Division of subjects by diagnosis showed that only in the Alzheimer's group did hearing impairment predict more rapid cognitive decline at follow‐up, and this difference persisted after adjustment for the greater age of hearing impaired subjects.
The impact of hearing loss on quality of life in older adults.
TLDR
Severity of hearing loss was significantly associated with having a hearing handicap and with self-reported communication difficulties, and decreased function in both the Mental component Summary score and the Physical Component Summary score of the SF-36 as well as with six of the eight individual domain scores.
Mild cognitive impairment: clinical characterization and outcome.
TLDR
Patients who meet the criteria for MCI can be differentiated from healthy control subjects and those with very mild AD, and appear to constitute a clinical entity that can be characterized for treatment interventions.
Age, neuropathology, and dementia.
TLDR
The association between the pathological features of Alzheimer's disease and dementia is stronger in younger old persons than in older old persons, and age must be taken into account when assessing the likely effect of interventions against dementia on the population.
Generational differences in the prevalence of hearing impairment in older adults.
TLDR
The results suggest that 1) older adults may be retaining good hearing longer than previous generations and 2) modifiable factors contribute to hearing impairment in adults.
Age-specific incidence rates of Alzheimer’s disease
TLDR
Incidence rates for AD in the Baltimore Longitudinal Study of Aging are consistent with published rates in other studies, and the longitudinally followed subjects of the BLSA offer a unique opportunity to prospectively investigate the antecedents of AD.
Hearing and cognition in the elderly. New findings and a review of the literature.
TLDR
There was no evidence for a major effect of hearing acuity on cognitive function over time in this group of healthy elderly and review of published studies suggests that hearing ability is related to cognitive status in demented subjects, but there is little to suggest that in the normal elderly, hearing impairment leads to cognitive decline.
Characteristics and Comorbidities of Rural Older Adults with Hearing Impairment
TLDR
The Rural Health Promotion Project was a Medicare-funded demonstration project under which beneficiaries were offered health screenings and disease risk factor interventions at no cost and whether such services lead to decreased use of other health care services and to assess their impact on long-term health outcomes.
