EFFECTS OF PHYSICAL ACTIVITY ON THE MEMORY IN 50-70 YEAR-OLD-WOMEN WITH MILD COGNITIVE IMPAIRMENT

هدف: جهان در حال پير شدن است. افزايش طول عمر و در نتيجه تعداد سالمندان ، باعث بروز نگراني درخصوص مشكلات پيش رو و اجتناب ناپذير خاص اين دوران مي گردد از هر 10 نفر بالاي 65 سال انتظار مي رود يك نفر مبتلا به بيماري الزايمر باشد و اين نسبت در افراد بالاي 85 سال به 4 نفر از 10 نفر افزايش مي يابد.الزايمر بيماري پيشرونده است كه در صورت عدم مداخله به مراحل پيشرفته تر ميرسد. برخي روش ها نشان داده اند كه ميتوانند در پيشگيري و كند كردن سير بيماري موثر باشند.هدف اين مطالعهبررسي تاثير فعاليت بدني بر سطح كاركرد حافظه زنان 70-50 سال مبتلا به اختلال حافظه است. روش بررسي:اين تحقيق نيمه تجربي است و با.16 آزمودني زن( ميانگين سن 5/6± 1/61)، 5 /0MCI = (آسيب شناختي خفيف)، بي سواد و بدون فعاليت منظم بدني و ذهني اجرا گرديد. توزيع افراد در گروه هاي تمرين(فعاليت بدني) و كنترل(بي تمريني) به روش تصادفي صورت گرفت(تعداد نفرات هر گروه=هشت نفر).طول دوره مداخله به مدت سه ماه، سه جلسهدر هفته و هر جلسه به مدت 60 دقيقه برگزار شد. آزمون سطح كاركرد مغزCDR ) ) و روش تجزيه و تحليل آنكوا، تعقيبي بونفروني و آزمون تي زوجي استفاده گرديد. يافته ها: نتايج نشان داد روش مداخله اي فعاليت بدني در افزايش سطح حافظه زنان 70-50 سال با اختلال حافظه، تاثير معناداري در سطح معناداري 05/0 داشته است و تاثير پذيرترين خرده مقياس، خرده مقياس حافظه بوده است. نتيجه گيري: اجراي برنامه هاي بدني بر حافظه بيماران با آسيب شناختي كم، تاثير دارد.

Aim and Background: The world is aging. The increase of lifetime and number of elderly people causes some concerns about the future and inevitable problems that will exist for this particular period of time. Alzheimer is a progressive disease, which reaches more advanced stages in case of non-intervention. Some of the methods including physical and mental activities have shown that they can be effective in preventing and slowing disease progression. The objective of this study is also verifying the effect of physical activities on the memory function level of the 50-70 year-old-women who are affected by memory impairment. Materials and Methods: 16 female subjects (mean age 61/1 ± 6/5) with MCI = 0.5 (mild cognitive impairment), illiterate, healthy (Based on the medical view for participation in physical activities) and without regular physical activities in Tehranelderly nursing home were selected. The randomly practices intervening: experimental group was thephysical activities and the control group (control) wasthe one without any activities. (Each group consisted of eight persons). Duration of intervening was three months, three sessions per week and each session lasted 60 minutes. For the diagnosis of dementia, the Clinical Dementia Rating (CDR) was used. Also in order to control the depression level, before and after implementation of the plan, the Geriatric Dementia Scale (GDS) was carried out. To evaluate the data,paired t-test, ANCOVA analysis method and the Bonferroni post hoc were used. Results: The results indicated that intervening method(physical exercise) had significanteffect onthe memory impairment in increasing the memory level of the 50-70 year-old-women with MCI. Being affected for subscales was the memory subscale. In this consideration, no changes were observed in the depression level and then the level of depression has not interfered in the function level of the participators. Conclusions: In this study, interventional procedure including physicalexercise caused an improvement in the memory of 50-70-year-old women with mild cognitive impairment. Therefore, doing the physical performance in patients with mild cognitive impairment is effective.
