Objective:To investigate the effects of single sensory impairment (SSI; visual or auditory) or dual sensory impairment (DSI; visual and auditory) on dementia and longitudinal changes of neuropsychological test scores.Methods:In this nationwide, prospective, community-based elderly cohort study, Korean Longitudinal Study on Cognitive Aging and Dementia (KLOSCAD), 6,520 elderly individuals (58-101 year) representing the general population were included. We defined visual and auditory sensory impairment via self-report questionnaire: 932 had a normal sensory function, 2957 had a SSI, and 2631 had a DSI. Demographic and clinical variables including cognitive outcomes were evaluated every two years over six years. Through logistic regression, Cox regression, and linear mixed model analysis, the relationship between SSI or DSI and dementia prevalence, dementia incidence, and change in neuropsychological scores were evaluated.Results:At baseline, DSI was significantly associated with increased dementia prevalence compared to normal sensory function (OR=2.17, 95% CI [1.17–4.02]), but SSI was not (OR=1.27, 95% CI [0.66–2.41]). During the 6-year follow-up, the incidence of dementia was significantly higher in the DSI group than in the normal sensory function (HR=1.9, 95% CI [1.04–3.46]), and neuropsychological scores significantly decreased (β=-0.87, 95% CI [-1.17–-0.58]).Conclusions:Our results suggest that coexisting visual and hearing impairments facilitate dementia prevalence, dementia incidence, and cognitive decline, but visual or hearing impairment alone do not. Additionally, visual and hearing impairment may lead to dementia or cognitive decline independent of Alzheimer’s pathology.

Abstract Objectives We aimed to determine whether self-assessed single (hearing or visual) and dual sensory (hearing and visual) impairments are associated with cognitive decline and incident possible cognitive impairment, no dementia (CIND) and probable dementia. Method Data were drawn from the 1996–2014 surveys of the Health and Retirement Study (HRS), involving 19,618 respondents who had no probable dementia and who were aged 50 years or older at the baseline. We used linear mixed models to test the association between self-assessed sensory impairment and cognitive decline followed by a Cox proportional hazard model to estimate the relative risk of incident possible CIND and probable dementia associated with the presence of sensory impairment. Results Respondents with self-assessed single and dual sensory impairment performed worse in cognitive tests than those without sensory impairment. The fully adjusted incidence of developing possible CIND was 17% higher for respondents with hearing impairment than those without hearing impairment. Respondents with visual impairment had 35% and 25% higher risk for developing possible CIND and probable dementia, respectively, than those without visual impairment. Respondents with dual sensory impairment at baseline were 38% and 26% more likely to develop possible CIND and probable dementia, respectively, than those with no sensory impairment. Discussion Self-assessed sensory impairment is independently associated with cognitive decline and incident possible CIND and probable dementia. Further studies are needed to identify the mechanism underlying this association and to determine whether treatment of sensory impairment could ameliorate cognitive decline and delay the onset of dementia among older adults.

Aims.The aims of this study were to investigate the effects of either hearing, vision or dual sensory impairment on depressive symptoms and to identify subgroups that are vulnerable and significantly affected.Methods.Data from the 2006–2014 Korean Longitudinal Study of Aging (KLoSA) were used and a total of 5832 individuals were included in this study. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression (CES-D10) scale. Sensory impairment was assessed according to the levels of self-reported hearing or vision, which were categorised as either good (excellent, very good or good) or poor (fair or poor). The changes in hearing or vision from records of previous survey were investigated. Changes from good to poor, which indicates new onset, were defined as hearing impairment or vision impairment. Interactions of changes in hearing and vision were considered in the analysis. Dual sensory impairment was indicated when hearing impairment and vision impairment both developed at the same time. Demographic, socioeconomic and health-related factors were considered as potential confounders and were adjusted for in the generalised estimating equation model.Results.Individuals with hearing impairment demonstrated significantly more severe depressive symptoms [β = 0.434, standard errors (s.e.) = 0.097, p < 0.001] than those who had good hearing. Those with vision impairment also showed significantly elevated depressive symptoms (β = 0.253, s.e. = 0.058, p < 0.001) than those with good vision. When the interactions between hearing and vision were considered, participants with dual sensory impairment showed significantly more severe depressive symptoms (β = 0.768, s.e. = 0.197, p < 0.001) than those with good hearing and vision. The effect of a single and dual sensory impairment on depressive symptoms was significant in both sexes and across age groups, except for vision impairment in male participants.Conclusions.Hearing, vision and dual sensory impairment are significantly associated with depressive symptoms. Our results suggest that treatment or rehabilitation of either hearing or vision impairment would help prevent depression.

The Relationship

Abstract Hearing and vision impairment have been independently linked to accelerated cognitive decline in older adults, however there is limited evidence on the effect of dual sensory impairment (DSI) (both hearing and vision impairment) on cognition. Additionally, the impact of social isolation and loneliness, both correlates of DSI and independent risk factors for cognitive decline, on the DSI-cognition relationship has yet to be studied. Using data from the National Social Life, Health, and Aging Project (N=3,091), multivariable linear regression models were used to describe the cross-sectional relationship between self-reported functional sensory impairment (none, hearing only, vision only, DSI) and cognitive function, measured by the survey adapted Montreal Cognitive Assessment. We also included an interaction term in the model to investigate whether cognition is worse among older adults with sensory impairment who also are socially isolated or lonely. Participants in this sample are between 62-91 years with 15% reporting hearing impairment, 11% reporting vision impairment, and 7% reporting DSI. DSI was associated with significantly lower global cognitive function compared to no sensory impairment (-0.31 standard deviations (SD), 95% CI:-0.44 to-0.18), hearing impairment alone (-0.29 SD, 95% CI: -0.44 to -0.15), and vision impairment alone (-0.22 SD, 95% CI: -0.39 to -0.06). Furthermore, cognitive function was significantly worse among older adults with both DSI and smaller social networks (p-interaction <0.05). No differences in the DSI-cognition relationship were observed by level of loneliness. These findings add to the limited research on the relationship between DSI, social isolation and loneliness, and cognition.

Dual Sensory Impairment

Abstract Vision and hearing impairment are common and independently linked to dementia risk. Adults with concurrent vision and hearing impairment (dual sensory impairment, DSI) may be particularly at-risk. Data were from the National Health and Aging Trends Study (NHATS) (2011–2018, N=7,562). Functional sensory impairments were self-reported (no impairment, vision only, hearing only, and DSI). We calculated age-specific prevalence of sensory impairments. Discrete time proportional hazards model with a complementary log-log link were used to assess 7-year dementia risk. Of 7,562 participants, overall prevalence of functional vision, hearing and DSI was 5.4%, 18.9% and 3.1%, respectively. DSI prevalence increased with age, impacting 1 in 7 adults ≥90 years. DSI was associated with a 50% increased 7-year dementia risk (adjusted hazard ratio 1.50; 95% confidence interval, 1.12–2.02) compared to no impairment. Sensory rehabilitative interventions for multiple impairments may be an avenue for consideration in efforts to reduce dementia risk.

Objective: The objective of the study is to examine the association of auditory, vision, and dual sensory impairment with late-life depressive and anxiety symptoms. Method: Our study included 7,507 older adults from the National Health & Aging Trends Study, a nationally representative sample of U.S. Medicare beneficiaries. Auditory and vision impairment were determined by self-report, and depressive and anxiety symptoms were evaluated by the two-item Patient Health Questionnaire (PHQ-2) and two-item Generalized Anxiety Disorder Scale (GAD-2), respectively. Results: Auditory, vision, and dual impairment were associated with an increased risk of depressive and anxiety symptoms in multivariable analyses accounting for sociodemographics, medical comorbidity, and functional impairment. Auditory, vision, and dual impairment were also associated with an increased risk for depressive and anxiety symptoms that persist or were of new onset after 1 year. Discussion: Screening older adults with sensory impairments for depression and anxiety, and screening those with late-life depression and anxiety for sensory impairments, may identify treatment opportunities to optimize health and well-being.

Background. There is an increase in dual sensory impairment (DSI) (hearing and visual) with increase in elderly population. Most causes of DSI among elderly are treatable. This study determines the prevalence and characteristics of dual sensory impairment among elderly of a rural community. Material and Methods. A cross-sectional study conducted among 175 rural elderly. Visual acuity for distant vision was measured using Snellen E chart. Hearing ability was measured using pure tone audiometry. Results. The prevalence of hearing impairment was 72% and that of visual impairment was 48%. The overall prevalence of DSI among the study subjects was 17.7% and 32.6% depending on whether traditional pure tone average or high-frequency pure tone average was used to define moderate or worse degree of hearing impairment. DSI prevalence increased significantly with increase in age. DSI was higher among widow/ers and illiterates, who did not have any source of income and those who were financially dependent on others compared to their counter groups. Conclusion. Prevalence of DSI is high among community dwelling rural Indian elderly. Individuals with DSI produce unique challenges in rehabilitation. A team approach at primary health care level is necessary to diagnose and rehabilitate elderly thereby enabling them to easily lead an independent life.

Abstract Using data from 46,029,364 Medicare beneficiaries included in the 2015 Current Beneficiary Survey (MCBS), we examined the relationship between dual sensory impairment (DSI) – concurrent vision impairment (VI) and hearing impairment (HI) – and accompaniment to physician visits. Analyses examined reasons for accompaniment and self-reported sensory impairment was categorized as: no sensory impairment (89%), hearing impairment (HI) only (5%), vision impairment only (4%), and DSI (1%). There was no difference in odds of accompaniment among HI compared to those without sensory impairment (odds ratio [OR] = 1.04; 95% Confidence Interval [CI]: 0.84,1.29); however, VI and DSI were associated with accompaniment: (OR=2.14; [CI]:1.6,2.8 and [OR]= 2.70; [CI]:1.55,4.72, respectively). Our study further demonstrates that older adults with sensory impairment are accompanied to physician visits more often than those without sensory impairment, and transportation is the most frequently reported reason for accompaniment among adults with VI and communication for those with HI.

Abstract Objectives Although visual and hearing impairments have been found to be associated with cognitive decline in the old age, the mechanism underlying this relationship remains unclear. This study aimed at assessing the predictive role of visual and hearing difficulties on subsequent cognitive functioning. Method From the cohort of the first (2002) and fifth waves (2010) of the English Longitudinal Study of Ageing (ELSA), 3,508 individuals aged 60 and older were included in the study. Five self-reported visual and hearing functioning items were used to assess sensory functioning at baseline. Cognition was assessed 8 years later by means of four measured tests covering immediate and delayed recall, verbal fluency, and processing speed. A Multiple Indicators Multiple Causes approach was used to assess the longitudinal associations of visual and hearing functioning with cognitive difficulties. A multigroup longitudinal measurement invariance was used to estimate latent change in cognitive difficulties across groups of participants presenting either visual, hearing, or dual sensory impairment (i.e., those reporting difficulties in both visual and hearing functioning items). Results Visual (β = 0.140, p < .001) and hearing (β = 0.115, p < .001) difficulties predicted cognitive difficulties 8 years later. The latent increase in cognitive difficulties was steeper in people with visual impairment (d = 0.52, p < .001), hearing impairment (d = 0.50, p < .001), and dual-sensory impairment (d = 0.68, p < .001) than those non-impaired (d = 0.12, p < .001). Discussion Visual and hearing difficulties were identified as predictors of subsequent cognitive decline in the old age. Interventions to prevent visual and hearing difficulties may have a substantial impact to slow down subsequent age-related cognitive decline.
