Zusammenfassung
Die Untersuchung kognitiver Fähigkeiten erlangt vor dem Hintergrund des demografischen Wandels zunehmend Relevanz. Die Frage nach dem Effekt einer Cochleaimplantation bei taub geborenen Kindern im Vergleich zu Hörgesunden stand noch bis vor wenigen Jahren im Fokus. Es stellt sich heute die Frage, ob eine Hörrehabilitation bei Älteren, z. B. mithilfe eines Cochleaimplantats (CI), einen protektiven Effekt auf die kognitiven Fähigkeiten und damit auch auf das Demenzrisiko besitzt. Die vorliegende Übersichtsarbeit behandelt die Verknüpfungen der kognitiven Fähigkeiten mit Hörstörungen und Cochleaimplantation. Historische Aspekte der Intelligenztestung werden beschrieben. In der aktuellen Literatur sind Erkenntnisse über kognitive Aspekte bei älteren hörgestörten Patienten und CI-Trägern rar. Erste Untersuchungsergebnisse weisen einen positiven Zusammenhang von Hörverbesserung und Kognition aus. Im Umgang mit kognitiven Defiziten und hörgestörten Patienten sind weitere Untersuchungen zur Erarbeitung von Handlungsempfehlungen dringend erforderlich.
Abstract
The relevance of assessing cognitive functioning is increasing against the background of the continuing demographic changes. Up to a few years ago the focus was on the effects of cochlear implantation in children born deaf in comparison to healthy individuals. Currently, the question arises whether hearing rehabilitation in the elderly, e.g. by postlingual cochlear implantation, has a protective effect on cognitive functioning and therefore on the risk of onset of dementia. This review describes the association of cognitive functioning with hearing disorders and cochlear implantation. Historical aspects of intelligence testing are illustrated. Knowledge on cognitive aspects in elderly persons with hearing disorders and cochlear implants is rare in the currently available literature. Initial findings indicate a positive correlation between hearing improvement and cognitive functioning. Further studies are urgently required in order to elucidate appropriate guidelines for the treatment of patients with cognitive deficits and hearing impairment.
