“…64 The findings with regard to the interrelationship between visual performance and cognition are, in many ways, similar to the findings reported between hearing and cognition. Visual impairment has been shown by some 65,66 to be a risk factor for cognitive decline among the elderly. Visual acuity in participants aged 20 to 80 years predicted about half of the agerelated variance in a general cognition factor, 67 and artificially blurring the near vision of young healthy participants resulted in poorer performance on nonverbal cognitive tests.…”

and visual impairment. Herein, we focus on the difficulties experienced by those who have acquired hearing and vision loss associated with age-related changes and pathologic conditions. Most individuals with age-related DSI experience gradual onset of mild to moderate sensorineural hearing loss and vision loss. Awareness of late-onset DSI among older individuals is increasing, presumably because the size of this population is growing rapidly. However, there is almost no research on rehabilitation for this population; therefore, there is a tremendous imperative to develop and test rehabilitation strategies.Although there are clear definitions of degrees of vision impairment and hearing impairment, definitions of DSI are lacking, and determination of a standardized definition is complex. Proposed definitions are functional in nature and tend to be nonspecific, with few implications for clinical practice. For instance, Davenport 5 suggests that DSI is "any combination of hearing and vision loss that interferes with access to communication and the environment and requires interventions beyond those necessary for hearing or vision loss alone." This generality is in part due to the fact that there is an unknown, and presumably variable, interaction between the two impairments. As D ual sensory impairment (DSI) refers to the presence of both hearing loss and vision loss. According to the Centers for Disease Control and Prevention, 1 at least 1.7 million people report DSI. Studies show that between 9% and 21% of adults older than 70 years have some degree of DSI [2][3][4] and that the prevalence increases with age. As pointed out by Desai et al, 1 as the population ages, so will the number of individuals with DSI.Individuals with DSI can be classified into the following 4 groups: congenital deafblindness, congenital visual impairment with acquired hearing impairment, congenital hearing impairment with acquired visual impairment, and acquired hearing Dual sensory impairment (DSI) refers to the presence of both hearing loss and vision loss. The occurrence of DSI is particularly prevalent among the aging population, with studies showing between 9% and 21% of adults older than 70 years having some degree of DSI. Despite this, there is little direction regarding recommended clinical practice and rehabilitation of individuals with DSI. It is assumed that the problems encountered by individuals with DSI are considerably greater than the effects of vision impairment or hearing impairment alone, because when these two sensory impairments are combined, the individual is seriously deprived of compensatory strategies that make use of the nonimpaired sense. In this article, the literature available regarding DSI is summarized, and research needs regarding rehabilitation strategies are outlined and discussed. Simple suggestions for addressing DSI are provided that use available tools and technology.

“…In the recent Singapore Malay Eye Study (Ong et al 2012), people with visual impairment both before and after refractive correction were significantly more likely to have cognitive dysfunction. In a study on 2140 non-institutionalized Mexican Americans aged 65 and older with a follow-up of up to 7 years, near vision impairment, but not distance vision or hearing impairments, was associated with cognitive decline (Reyes-Ortiz et al 2005). A magnetic resonance imaging study showed a regional expansion of grey matter volume in area V2 contralateral to the eye operated on cataract, at 6 weeks after cataract surgery (Lou et al 2013).…”

“…First, the study design was cross-sectional, so caution must be used in the interpretation of the observed associations. However, there is emerging evidence from large-cohort longitudinal studies regarding the role of oral health in cognitive status, which may help to elucidate the mechanism [11,13,14,[23][24][25]. Secondly, cognitive status and mastication performance were ascertained by use of self-reported measures.…”

“…Poor oral health and nonoptimal mastication have been introduced as potential modifiable risk factors for cognitive impairment [9][10][11][12][13][14]. In fact, the regular sensory stimulation in the course of mastication increases the cerebral blood flow and the number of pyramidal cells in the hippocampus [15][16][17][18][19][20].…”
