“…However, hearing aid use was reported to be similarly high in studies that reported using behind-the-ear style aids. Allen et al (2003), Nguyen et al (2017) and Adrait et al (2017) reported a tendency for greater improvement in hearing disability, general quality of life and cognition among those who used hearing aids more often compared to those who used them less frequently.…”

“…All remaining studies were of low-tomoderate quality, and consisted of low-level evidence, such as single case reports, small case series or uncontrolled and underpowered treatment trials. Only five papers (Adrait et al, 2017;Hopper et al, 2016;Mamo et al, 2017;Nguyen et al, 2017;Whitson et al, 2013) The most commonly included outcome measures were hearing/vision-related disability and behavioural and psychological symptoms of dementia. Addressing sensory impairments may have additional benefits in other areas (e.g.…”

“…Hearing interventions mostly involved provision of a hearing aid, with five studies reporting on provision of a hearing aid (Adrait et al, 2017;Allen et al, 2003;Ghiringhelli and Iorio, 2013;Hutchinson et al, 2012;Hutchison et al, 2012;Nguyen et al, 2017;Palmer et al, 1999;Palmer et al, 1998), and one additional study reporting on the impact of hearing aid 'trouble shooting' (Haque, 2012) (Aazh et al, 2015). Palmer et al (1999; reported selecting a harder to remove in-the-ear style hearing aid rather than a behind-the-ear style aid.…”

“…The benefits of assistive listening devices on communication may be apparent in more realistic adverse listening conditions. Nguyen et al (2017), Adrait et al (2017) and Allen et al's (2003) studies were the only studies that reported outcomes related to cognitive function, activities of daily living and caregiver burden. However, none of these studies reported any benefit of hearing aids in relation to these outcomes.…”

Background:Age-related hearing and vision problems are common among people with dementia and are associated with poorer function, reduced quality of life and increased caregiver burden. Addressing sensory impairments may offer an opportunity to improve various aspects of life for people with dementia.Methods:Electronic databases were searched using key terms dementia, hearing impairment, vision impairment, intervention, and management. Database searches were supplemented by hand searching bibliographies of papers and via consultation with a network of health professional experts. Studies were eligible for inclusion if they included adults aged over 50 with dementia with adult-onset hearing or vision impairment who had received a hearing or vision intervention in relation to cognitive function, rate of decline, psychiatric symptoms, hearing/vision-related disability, quality of life, and/or caregiver burden outcomes. A range of study designs were included. Results were summarized descriptively according to level of evidence and effect sizes calculated where possible. Risk of bias was assessed using Downs and Black's (1998) checklist. The development of the intervention was summarized according to the CReDECI2 scheme. PROSPERO review registration number 2016:CRD42016039737.Results:Twelve papers describing hearing interventions and five papers describing vision interventions were included. Most were of low to moderate quality. One high quality randomized controlled trial of a hearing aid intervention was identified. Hearing interventions included provision of hearing aids, assistive listening devices, communication strategies, hearing aid trouble shooting, and cochlear implantation. Vision interventions included prism lenses, rehabilitation training, and cataract surgery. There was no consistent evidence for the positive impact of hearing/vision interventions on cognitive function, rate of cognitive decline, quality of life, or caregiver burden.Conclusion:Sensory interventions may promote better outcomes, but there is a need for properly powered, controlled trials of hearing and vision interventions on outcomes relevant to people living with dementia.

“…In the few studies that have been conducted that assessed the cognitive abilities of adults with dementia following HA fitting, results have not shown substantial improvements in cognitive function. Nguyen and colleagues 78 and Adrait and colleagues 79 described a multicenter randomized control trial to determine if the use of HAs improves cognition and behavior in 51 individuals with probable Alzheimer's disease and hearing loss. In their companion papers, participants were randomly assigned to either active HA group or a placebo HA group for 6 months.…”

Dementia and Hearing Loss: Interrelationships and Treatment Considerations

Hearing loss is common among typically aging older adults and those with dementia. In recent years, there has been a renewed interest in the relationship between hearing and cognition among older adults, and in hearing loss as a modifiable risk factor for dementia. However, relatively less attention has been focused on the management of hearing loss among individuals with dementia and the key roles of speech-language pathologists and audiologists in providing such care. In this article, the authors review the literature on hearing loss and dementia, and analyze the research evidence for treatment of hearing loss in the context of major neurocognitive disorders, such as Alzheimer's disease. This article provides an up-to-date review of research evidence for hearing interventions, as well as recommendations for speech-language pathologists and audiologists to work together to ensure access to hearing health care and increased opportunities for meaningful life engagement for people with dementia and hearing loss.

T A B L E O F C O N T E N T S A B S T R A C TThis is the protocol for a review and there is no abstract. The objectives are as follows:To evaluate the effectiveness of hearing aids for mild to moderate hearing loss in adults who have been prescribed at least one hearing aid. B A C K G R O U N D Description of the conditionHearing loss is the most prevalent sensory deficit (Mathers 2000); it represents a major public health issue with substantial economical and societal costs. Untreated, adult hearing loss results in communication difficulties that can lead to social isolation and withdrawal, depression and reduced quality of life (Davis 2007). Hearing loss is also associated with an increased risk of dementia (Lin 2011). According to the World Health Organization hearing loss is the 13th most common global disease burden and the third leading cause of years living with disease (WHO 2008). Disabling hearing loss is estimated to affect 360 million persons globally (5.3% of the world's population) (WHO 2012a). The prevalence of hearing loss increases with age (Akeroyd 2014), and given the ageing society it is predicted that by 2030 adult-onset hearing loss will be the seventh largest disease burden, above diabetes and human immunodeficiency virus (HIV) (WHO 2008). Epidemiological data suggest that the majority of cases of hearing loss in adults are sensorineural (92%) and bilateral (94.8%) (Cruickshanks 1998). There are numerous definitions of hearing loss across different countries and organisations (Timmer 2015). In this review, hearing loss is defined according to pure-tone thresholds averaged across 0.5 kHz, 1.0 kHz, 2.0 kHz and 4.0 kHz in the better-hearing ear, consistent with the World Health Organization grades of hearing impairment (Mathers 2000). The majority of hearing losses (92%) are those that are defined as mild or moderate (AoHL 2015). Mild (or slight) hearing loss is indicated as 26 to 40 dB hearing level (HL) and described as the ability to hear and repeat words spoken in a normal voice at one metre. Moderate hearing loss is indicated as 41 to 60 dB HL and described as the ability to hear and repeat words using a raised voice at one metre (Mathers 2000). In addition to a loss of hearing sensitivity, there may be additional sensory deficits of temporal and spectral pro-

Do Hearing Aids Influence Behavioral and Psychological Symptoms of Dementia and Quality of Life in Hearing Impaired Alzheimer’s Disease Patients and Their Caregivers?

Abstract: These findings do not provide evidence of improvement in behavioral symptoms, functional status, or QoL of hearing impaired AD patients and their caregivers after 6 months of HA use. However, we cannot exclude that HAs may have a positive effect in patients aged less than 75 years.
