Objective:
To compare the cognitive evolution of older adults with severe or profound hearing impairment after cochlear implantation with that of a matched group of older adults with severe hearing impairment who do not receive a cochlear implant (CI).
Design:
In this prospective, longitudinal, controlled, and multicenter study, 24 older CI users were included in the intervention group and 24 adults without a CI in the control group. The control group matched the intervention group in terms of gender, age, formal education, cognitive functioning, and residual hearing. Assessments were made at baseline and 14 months later. Primary outcome measurements included the change in the total score on the Repeatable Battery for the Assessment of Neuropsychological Status for Hearing impaired individuals score and on its subdomain score to assess cognitive evolution in both groups. Secondary outcome measurements included self-reported changes in sound quality (Hearing Implant Sound Quality Index), self-perceived hearing disability (Speech, Spatial, and Qualities of Hearing Scale), states of anxiety and depression (Hospital Anxiety and Depression Scale), and level of negative affectivity and social inhibition (Type D questionnaire).
Results:
Improvements of the overall cognitive functioning (
p
= 0.05) and the subdomain “Attention” (
p
= 0.02) were observed after cochlear implantation in the intervention group; their scores were compared to the corresponding scores in the control group. Significant positive effects of cochlear implantation on sound quality and self-perceived hearing outcomes were found in the intervention group. Notably, 20% fewer traits of Type D personalities were measured in the intervention group after cochlear implantation. In the control group, traits of Type D personalities increased by 13%.
Conclusion:
Intervention with a CI improved cognitive functioning (domain Attention in particular) in older adults with severe hearing impairment compared to that of the matched controls with hearing impairment without a CI. However, older CI users did not, in terms of cognition, bridge the performance gap with adults with normal hearing after 1 year of CI use. The fact that experienced, older CI users still present subnormal cognitive functioning may highlight the need for additional cognitive rehabilitation in the long term after implantation.
The Nijmegen Cochlear Implant Questionnaire (NCIQ) is a specific and quantifiable self-assessment health-related quality of life (QoL) questionnaire. It was developed to determine the subjective benefits of a cochlear implant (CI). The present study aimed to determine the validity and reliability of the NCIQ in Spanish. Seventy-six adult, Spanish speaking, CI users and 28 control subjects answered the NCIQ. Reliability of the questionnaire was determined using Cronbach's α coefficient and the validity established using Pearson's correlation coefficient. All questionnaire respondents performed significantly better in all sub-domains with a cochlear implant than before cochlear implantation. The Cronbach's α score exceeded 0.70 in most sub-domains and the total score. The objective measures: bisyllables tested without lip-reading and with masking; and bisyllables, tested without lip-reading and without masking were correlated with the sub-domain 'advanced sound perception'. To determine health-related QoL the NCIQ in Spanish is a reliable self-assessment questionnaire and a valuable instrument in determining the subjective benefit of a CI.
Supracricoid partial laryngectomy is an oncologically safe procedure to preserve laryngeal functions in selected patients with glottic and supraglottic carcinomas.
Elderly cochlear implant users experience an improvement in their quality of life, with outcomes similar to those achieved in younger adults. Particular attention must be paid to the possibility of age-related conditions in the elderly that may increase the risks of surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
