Investigating the Factors Affecting Cognitive Impairment in the Elderly

As people age, numerous physical and cognitive illnesses appear in the elderly and their quality of life declines sharply. One of the most common problems in this period is cognitive impairment in the elderly. The purpose of this study is to review the factors affecting cognitive impairment in the elderly in order to assist physicians, nurses, families and the relatives of elderly in preventing, controlling and treating these disorders.

In this review, the PubMed, Scopus and Wiley Online Library databases were searched by the end of 2019, and finally 10 papers were selected among 47 publications, and investigated.

The total number of subjects studied in this study was 21163 in 10 publications, which included 6 cohort studies, 2 Interventional studies and 2 A randomized controlled trial studies.

Stress, distress and depression, snoring and inadequate sleep, can affect the hippocampus, and cause cognitive impairments, memory impairment or even dementia. Regular exercise and daily intake of foods containing omega-3 and other antioxidant compounds delay the process of cognitive impairment in the elderly.
