Progress in the research of motoric cognitive risk syndrome / 中华神经科杂志

As the population ages worldwide,dementia patients increase at a high rate of 7.7 million each year,which has a huge impact on quality of life of the elder.It is not surprising,therefore,that early detection of individuals at high risk for dementia and the development of effective interventions are major public health priorities.There is increasing evidence that gait slowing occurs early in the course of dementia,precedes declines in cognitive tests,and is a strong predictor of dementia.Hence,incorporating gait performance into risk assessments is a novel and simple approach that can help improve dementia prediction.The motoric cognitive risk syndrome (MCR) is a predementia syndrome characterized by the presence of cognitive complaints and slow gait in older individuals without dementia or mobility disability.In addition,studies have shown MCR as a predictor of other negative outcomes in older adults,including disability,falls and death.However,the concept of MCR is still in its early stage and approach to the syndrome is not yet well established in China.This review aims to demonstrate the various aspects of MCR syndrome including its pathophysiology,diagnosis,epidemiology,and relationship with other geriatric conditions.

MMSE Result of a Population aged above 55 in Rural Area of North China / 中国心理卫生杂志

Objective:to do a population study with MMSE in rural area of north China.Method:13 962 farmers aged 55 or above from four villages in Linxian of Henan province were tested with MMSE, with 3 different cut-off points according to different level of education in our sample.Result:in our sample, the average total score of MMSE was lower than Chinese norm, especially that of calculation. Those aged, with poor education, female, with low SES had lower scores in MMSE test. There was a negative correlation between score of MMSE and that of ADL (acitivity of daily living).Conclusion:female, age, poor education, low SES are risk factors for dementia.

Analysis of risk factors of dementia after stroke in elderly patients / 中国实用内科杂志

Objective\ To explore the risk factors of dementia induced by stroke.Methods\ 258 elder patients with stroke had been followed up for three months,including clinical neuropathy and neuropsychological tests.Multivariate noncondition stepwise Logistic model analysis was made after single variable analysis.Results\ There were 83 patients with dementia induced by stroke,175 patients without dementia after stroke.The morbidity was 32.2%.The following eight factors were associated with dementia i.e.,age,multiple lesions,left lesion,large area of cerebral hemorrhage or cerebral infarction,cerebral atrophy,hypertension,the history of stroke,and bilateral lesions.Conclusions\ Dementia induced by stroke is caused by multiple factors.It is closely correlated to numbers of cerebral lesions,the location of cerebral lesions and the size of brain tissue necrosis.The primary conditions of patients'cerebral function are also closely associated with the occurence of dementia.
