Hearing loss and verbal memory assessment among older adults

OBJECTIVE: Research has found that adults with hearing loss perform worse on cognitive testing than adults without hearing loss; however, heavy emphasis on tests involving auditory stimuli may overdiagnose cognitive impairment among individuals with hearing loss. This study compared visual- and auditory-verbal memory tests among adults with and without hearing loss. METHOD: Forty-one adults with hearing loss (HL) and 41 age-matched adults with normal hearing (NH) completed a neuropsychological battery that included auditory and visual versions of the Hopkins Verbal Learning Testing-Revised (HVLT-R). A RESULTS: Mixed-model ANOVA indicated significant group (HL vs. NH) by condition (visual, natural auditory, crossed auditory) interactions for HVLT-R performance, with large effect sizes. The HL group performed significantly worse than the NH group on the natural auditory version; however, the NH group performed significantly worse than the HL group on the crossed condition. The groups were equivalent on the visual condition and all other cognitive tests, showing small effect sizes. Moreover, for the HL group, visual HVLT-R correlated with other cognitive tests whereas auditory versions did not. CONCLUSION: Cognitively intact older adults with hearing loss appeared impaired on auditory-verbal memory assessment under typical administration conditions. Visual assessment of verbal memory showed evidence of superior validity and is a viable alternative method to assess memory function especially in older populations.

Characteristics of Adults With Unrecognized Hearing Loss

Purpose Early detection of hearing loss is important for providing support and intervention for adults with age-related hearing loss. However, many older adults have hearing loss that is unidentified. Because they do not present the problem at health care settings, there is a dearth of research on people with unrecognized hearing loss (URHL). This study elucidates differences between older adults with normal hearing, adults with recognized hearing loss (RHL), and adults with URHL. Method Participants included 130 adults, ages 55-85 years. Of these, 39 had hearing in the normal range (HNR), 61 had RHL, and 30 reported HNR but failed a hearing screen (i.e., URHL). Participants completed the Positive and Negative Affect Schedule (PANAS; Watson, Clark, & Tellegen, 1988 ) and a battery of neuropsychological tests. Results The URHL group reported more positive affectivity than the HNR and RHL groups on the PANAS. In addition, the URHL group was significantly older and more likely to be male compared to the HNR group. Importantly, age was not significantly correlated with PANAS. Positive affectivity accounted for unique variance in group membership even after accounting for age, gender, physical health, and cognitive health. Conclusions Older adults with URHL have more positive affectivity than older adults with HNR or RHL. This group may be prone to downplaying their difficulties; consequently, they may need to experience larger hearing deficits before seeking help. The findings highlight the need for research investigating the effectiveness of psychoeducation on the importance of formal hearing assessment verses relying on self-assessment in facilitating early and effective intervention among people with URHL
