Memory, executive functions and cognitive impairment in elderly population

Abstract

Cognitive functions refer to the superior brain or mental function. These processes are usually first to suffer cognitive impairment associated with ageing. The aim of this study was: to analyse the state of memory and executive functions in a sample of elder population with and without cognitive impairment; and compare the cognitive state between elder who live in a public home for the elderly and elder who live in their homes. Therefore, a screening test was carried out to check the cognitive impairment level (Cognitive Mini Test MEC-35), and after that, the Memory Alteration Test (T@M) and the Ring Test were applied. The participants were 24 subjects, 12 of which belonged to a public home for the elderly and the other 12 lived in their homes. The average age of the participants was 78. The study has allowed us to establish the significant relation between the cognitive deterioration level and the state of the memory and executive functions. Besides, sex was indifferent in memory as a variable, but not in executive functions. Finally, the fact of the people living in a public home show us no significant differences in the state of memory and executive functions compared to people who live in their homes.
