Abstract

Background and Aim: The number of people getting old is increasing and according to the latest reports, the highest growth will be over the next 50 years especially in low-income countries. Age-related changes in sensory sensitivity and acuity, especially in the cognitive processing, are the strongest scientific findings. The aim of the present review article was studying the effect of cognition and mild cognitive impairment on the auditory system as well as actions that can be used to improve and prevent the progression of the disease in the patients.
Methods: In the present review study, the latest articles about cognition, mild cognitive impairment, and auditory system in the databases Proquest, Scopous, Magiran, Springer, GoogleScholar, ScienceDirect, and PubMed, using related keywords were studied between 1988 and 2015.
Conclusion: Auditory and cognition are complementary and contain similar resources and processes, which are completely intertwined. The use of pure tone audiometry for the examination of the relationship between cognitive decline and auditory will not be enough, so it seems that the use of a more sensitive measure of auditory aspects such as the frequency selectivity and temporal processing, can show this relationship efficiently. On the other hand, the recent studies have shown that rehabilitation programs that are focused on increasing cognitive abilities can slow disease progression and also improves memory and cognitive function. Therefore, it is recommended that treatment interventions and cognitive rehabilitation be carried out for these people.
