| BackgroundWith the rapid increase of our elderly population in our country, the prevalence rateof dementia is also gradually increased. Mild cognitive impairment(MCI) refers to thetransition clinical state between normal aging and dementia, is the early signal ofdementia.It is important to study early diagnosis and intervention of mild cognitiveimpairment for preventing and delaying the dementia.Objects1. Through the epidemiological investigation, to determine the prevalence anddistribution of MCI in the elderly over60years old in rural areas of Taicang City;Toestablish MoCA norm of Taicang country,provide references for the research on eldlypeople’s cognitive level in differrent areas or with different characteristics.2.Based on the assessment and diagnosis of mild cognitive impairment, We usedthe cognitive training, physical exercise, mental intervention, social interaction andother means of intervention to search the measures and effective evaluation methods forcommunity elderly cognitive impairment group intervenetion.Subjects and methods1. Epidemiological cross-sectional investigation: an epidemiological survey andMoCA Version Scale Test among2063rural elders of over60years old in Taicang Cityunder the layered, obtained1954valid questionnaires. The investigation includes basicsurvey, mode of life, disease and MoCA Version Scale Test.2．Norm of MoCA: based on the results of the investigation situation, four normswere established:the whole norm,the gender norm,the education norm and the agesnorm. 3. Mild cognitive impairment comprehensive intervention: The epi-demiologicalinvestigation in the selection of elderly patients divided into intervention group andcontrol group, the intervention group299people, control group280people, takephysical training, memory training, implementation training, calculation training,language training etc.To observe the changes of the cognitive situation by MoCAVersion Scale test after one year of the intervention.Results1.Epidemiological cross-sectional investigation：the average score MoCA VersionScale test was16.16±6.53in the elderly over60years old in rural areas of TaicangCity, ordinary low scores. The MCI dramatically varied in the aspects of sex, age, livingconditions, income, education background, etc. Yet high incidence of MCI related toadvanced age, female, solitude, low income and educational level, etc.2. Norm of MoCA: in MoCA Version Scale test of7aspects and the total scoredramatically varies in the aspects of sex, age, education education background in theelderly over60years old in rural areas of Taicang City.In genders, Male in MoCAVersion Scale test of7aspects and the total score were significantly higher thanfemale;In age groups, with the increase of age, MoCA Version Scale test of7aspectsand the total score had been declined;In education background, With the degree ofreduction MoCA Version Scale test of7aspects and the total score had been declined.3.Mild cognitive impairment comprehensive intervention: we used physicaltraining, memory training, executive training, counting training, language training andother comprehensive means to intervent the mild cognitive impairment in the elderly.But because of the intervention in a relatively short time, we have not achieved theexpected results.Conclusion1．The prevalence of MCI in the elderly over60years old in rural areas of TaicangCity were associated with advanced age, female, solitude, low income and educationallevel. 2．Significant main effects of MoCA existed in different age groups, gender andeducation level.Accordingly,we founded4norms:the whole norm,the gender norm,theage norm and the education norm,which could serve as reference for further research3．We used physical training, memory training, executive training, countingtraining, language training and other comprehensive means to improve the cognitivestatus of the mild cognitive impairment in the elderly. But had not been achieved theexpected results. |
