ABSTRACT
The population of the developed countries is aging, thus the number of older people is increasing. At the same time the proportion of the diseases connected with the age is rising. When a person ages, his cognitive function fades away as well. Researchers have long noted that cognitive function of the elderly with defective hearing fades away faster than in normally hearing people. There are several theories explaining it, but this issue is still a matter of debate. Several researches were held recently regarding the impact of cochlear implantation on the level of cognitive function in the preoperative and postoperative periods. Controversial results were received which require further study of the issue. HI-MoCA and RBANS-H special test systems have been developed lately for the hearing impaired. These tests allow you to evaluate the change in cognitive function in people with hearing impairment, up to complete deafness. The tests are original MoCA and RBANS, but are adapted for people with hearing impairment. Thanks to these new instruments we will be studying the change of cognitive function in preoperative and postoperative periods which will allow us to evaluate the role of hearing in the decline in cognitive function of the elderly.
