中国老年人增龄性记忆改变
Objective Explore the characteristics of age related memory changes of older Chinese adults living in the community and memory changes relative to age,education,gender,and occupation.Methods The Multi dimensional Memory Assessment Scale(MMAS) was administered 50 young adults aged between 20 and 30,as well as 280 older adults between 50 and 91 years of age and from three counties and Changsha city of Hunan province,China.Results Comparing with young adults,the memory functions of Chinese adults over 50 decreased with aging and went down abruptly after 65 years old,except for everyday life memory.The explicit memory of older adults declined with age more significantly than implicit memory.For explicit memory,the impairment of associate learning occurred more early and severely than free recall and recognition.The age,education,occupation,and gender were significant predictors of the explicit memory,the implicit memory was predicted only by age,and education and gender were significant predictors of the everyday life memory.Conclusion The older Chinese adults perform poorly on the memory tests as compared with young adults,the rates of decline of different memory functions are different,and the age,education,occupation,and gender have effects on the different types of memory.
