Cognitive skills affect outcome of CI in children: A systematic review

Abstract

The degree of preoperatively cognitive disabilities is associated with the outcome after CI, thereby emphasizing why accurate cognitive tests are an important part of the preoperative evaluation of CI and pre-requisite for shared decision making. Furthermore, individual postoperative rehabilitation programs must be created depending on the child's cognitive ability.

Cognitive and outcome measures seem suboptimal in children with cochlear implants – a cross‐sectional study

“…Our study population was selected on the basis of voluntary participation in group 1, and there is a relatively large number of syndromic hearing loss in group 2 in our study. Nevertheless, our study population seems comparable to those described in the previous literature with regard to the occurrence of cognitive disabilities among children with CI . Thus, 30%–40% exhibit cognitive levels below the age mean.…”

“…Another potential source of differences between our study and previous ones relates to the many different cognitive tests being applied that make comparison rather complicated. A systematic review of the literature about the impact of cognitive capabilities on the outcome of CI identified more than 30 different tests in the included literature . The multiplicity of tests hampers comparison of the interventions in the different studies.…”

“…Nevertheless, our study population seems comparable to those described in the previous literature with regard to the occurrence of cognitive disabilities among children with CI. [1][2][3][4][5][6][7]21 Thus, 30%-40% exhibit cognitive levels below the age mean. The percentage may vary between studies due to the different representation of children with syndromes who are often also cognitively impaired.…”

Cognitive improvement after cochlear implantation in deaf children with associated disabilities

“…One problem is that the literature on monitoring longitudinal cognitive skills is often retrospective and does not evaluate the role that restored auditory functions have on non-verbal cognitive development. [10][11][12][13] Specifically, the purpose of our study was to monitor functional auditory and non-verbal cognitive skills over a 24-month period. A second aim was to define how cochlear implantation restored functional auditory skills may influence non-verbal cognitive functions at 12 and 24 months post-cochlear implantation.…”
