Updating Training Can Improve The Daily Living Abilities Of The Elderly With Mild Cognitive Impairment

The important early symptoms of elderly people with mild cognitive impairment(MCI)are executive functions(EFs)deficits and impaired working memory.Older adults with mild cognitive impairment show impairments in instrumental activities of daily living(IADL).Some studies have found that executive function can better predict the changes in the ability of daily living of the elderly,but which component has a decisive role in the ability of daily life of the elderly with mild cognitive impairment,so far no research has conducted direct discussion.Therefore,in the first experiment of this research,58 elderly people with mild cognitive impairment over 65 years of age in Northwest China were selected to perform tasks related to executive functions(inhibition tasks,digital conversion tasks,updating tasks),daily life ability scale,and found that The updating ability of the elderly with mild cognitive impairment is significantly related to daily living ability,especially instrumental daily living ability,but has nothing to do with inhibition and conversion ability.Experiment 2 Based on Experiment 1,62 elderly people with mild cognitive impairment over 65 years old were selected and divided into training group and control group,and 32 subjects in the training group were trained with N-back updating function.Before and after training,digital updating task,suppression task,conversion task,and spatial working memory breadth task were used to evaluate the two groups of subjects,and the training effect and the daily life ability migration effect were analyzed.The results show that compared with the control group,the training group The updating ability training improves the instrumental daily life ability.These results indicate that working memory updating training can improve the ability of daily living of elderly people with mild cognitive impairment,especially instrumental daily life,and updating function tasks have certain effects on cognitive intervention in elderly with mild cognitive impairment.
