The Effect Of Cognitive Training On Cognitive Function In Elderly People With Mild Cognitive Impairment

Mild cognitive impairment（MCI）is a transitional disorder in the pre-morbid stage of dementia.Patients present with standard basic life skills but impaired core memory or cognitive function.Cognitive function is the human brain’s response to external environmental stimuli.Cognitive function is composed of multiple fields such as memory,orientation,and language ability.Its influencing factors include aging,demographic characteristics,socio-economic and environmental factors,health factors,and the cognitive reserve capacity of the brain.There are two kinds of interventions for MCI cognitive function,including drug interventions and non-drug interventions,of which non-drug interventions include cognitive interventions,exercise interventions,exercise-cognitive interventions,and psychological interventions.Among them,continuous mental training is the most common international intervention method.The objective of this study was to assess the effect of cognitive training in intervening cognitive function in older adults with mild cognitive impairment（MCI）.In the L community,we eventually recruited 5 seniors with MCI,and mental intervention training led by social workers was taken after signing informed consent forms.The duration of the intervention was three months,with a total of 12 lessons,1lesson per week,with an average of 90 minutes per-session.The specific content of cognitive training includes three parts: memory training,3R therapy,and sensory integration training.The data collection had baseline measurements,post-intervention measurements,and follow-up after three months,The researcher counted Mo CA cognitive scores and evaluated the effects of the intervention through in-depth interviews.The results showed that the Mo CA score of the elderly changed significantly compared with the baseline score.The follow-up score after three months also showed that the cognitive training intervention had a significant effect on the improvement of the overall cognitive function of the members（t=-5.832,P=0.004,Cohen’s d=2.6）,especially the overall memory function was significantly improved（t=-7.484,P=0.002,Cohen’s d=3.3）.According to the interview data,the elderly who participated in the cognitive training believed that the intervention gave them a complete understanding of mild cognitive impairment（MCI）,which was very helpful for the improvement of their memory and language expression ability.The fun and innovation of the activity was one of the main motivations for them to participate in the entire intervention process.In summary,cognitive training interventions have a significant effect on improving cognitive function in older people with mild cognitive impairment（MCI）;interventions should focus on three dimensions: memory training,3R therapy,and sensory integration training;and the intervention lasts at least three months,with a frequency of once a week for 90 minutes.
