The purpose of this study was to find out the effects of electroencephalograph (EEG) power and coherence on cognitive function in normal elderly, non-demented elderly with mild cognitive impairment, and demented elderly during working cognition tasks. Forty elderly women (19 demented elderly, 10 non-demented elderly with mild cognitive impairment, 11 norma1 elderly) participated in this study, All subjects performed working cognition tasks with Raven's CPM while EEG signal was recorded, EEGs were measured continuously at rest and during the working cognition task. EEG power and coherence was computed over 21 channels: right and left frontal, central, parietal, temporal and occipital region. We found that there were more correct answers among normal elderly women than in other groups Owing the working cognition task, ${\Theta}$ wave at Fp1, Fp2 and F8, a wave at Fp2, ${\beta}$ wave at Fp1, Fp2. F4 and F8 of the frontal region was increased significantly in the demented elderly group. On the other hand. ${\Theta}$ wave at Fp1, Fp2 and F7, ${\beta}$ wave at Fp1, Fp2, F3 and F7 of the frontal region was increased significantly in the group of non-demented elderly with mild cognitive impairment. In contrast. in the normal elderly group, all of the ${\Theta}$ wave and ${\beta}$ wave at Fp1, Fp2, F3, F4, F7 and F8 of the frontal region (except ${\beta}$ wave at F3) was increased significantly, These results suggest that the nerves in prefrontal and right hemisphere regions were most active in the demented elderly group during problem solving, and the nerves in the prefrontal and left hemisphere lobe were most active in the group of non-demented elderly with mild cognitive impairment. In contrast, me majority of nerves in the frontal region were active in the normal elderly group.

PURPOSE: This study examined the effects of coordinative locomotor training on the physical factors for falls in the elderly with mild cognitive impairment. METHODS: This study examined thirty subjects diagnosed with mild cognitive impairment by the radiologic findings, history, and physical examination. The subjects were assigned to a control group (n = 15) or experimental group (n = 15, coordinative locomotor training). The experimental group underwent coordinative locomotor training for four weeks, with training sessions two times per week. The control group was given a fall-prevention education for 60 minutes without coordinative locomotor training. To evaluate the physical factors for falls, the lower extremity strength and the Korean version of the Fullerton advanced balance scale and biorescue were measured for balance. These tests were conducted before and after training. RESULTS: Significant differences were observed between the two groups after the four weeks of coordinative locomotor training for the elderly with mild cognitive impairment the experimental group had a greater degree of improvement in the physical factors for falls. CONCLUSION: These findings suggest that coordinative locomotor training may have a functional effect on fall-prevention and the mobility of the elderly with mild cognitive impairment. In addition, it is expected to provide systematic and effective data that can be used as a fall prevention program for the elderly with mild cognitive impairment in each institution.

Purpose : The purpose of this study was to determine the effects of a cognitive-exercise program using step on the cognitive function, gait, and depression of elderly with mild cognitive impairment. Methods : The subjects comprised 30 elderly people with mild cognitive impairment who used elderly welfare centers in the provinces A, B, and C between March 21 and June 7, 2019. They were divided into an experimental group (n=15) and a control group (n=15) before undergoing an experiment based on a pretest-posttest control group design. The lowenstein occupational therapy cognitive assessment-geriatric population was used to assess the subjects' cognitive function, while the 4-stage balance test, 30-second chair-stand test, timed up & go test, and functional reach test were employed to evaluate their gait. In addition, the beck depression inventory was used to measure their levels of depression. Results : The cognitive-exercise program using step enhanced the subjects' cognitive function and gait and reduced their levels of depression. Furthermore, statistically significant differences were found between the experimental group and the control group. Conclusion : The cognitive-exercise program using step promoted the process of sensorimotor and cognition through the learning process of various steps taking left and right steps and cognitive activities. It improves gait by activating the coordination of the musculoskeletal and nervous systems of the body and positively affecting posture control, balance, flexibility, and lower extremity muscles. It also relieved depression by performing successful step learning and cognitive activities with forward-looking (doing) that leads to pleasure and achievement. The present study confirmed the value of a cognitive-exercise program using step to treat multiple domains of functional decline in elderly patients with mild cognitive impairment. This is therefore proposed as an intervention program for this patient group.

Purpose: This study was conducted to identify the effects of a group cognitive improvement program on cognitive function, depression and self-esteem in elderly individuals with mild cognitive impairment. Methods: This was an experimental study that employed a pre-post design of a non-equivalence control group. The subjects were 52 elderly people with mild cognitive impairment, 25 of whom were assigned to the experimental group and 27 to the control group. The program was conducted for a total of 12 sessions for 60 minutes each. Data were analyzed using the ${\chi}2-test$, Fisher's exact test, and Independent t-test with the SPSS 20.0 program. Results: After the intervention, the group who participated showed improvement in all areas of cognitive function based on MMSE-KC (F=26.37, p.<0.001), the Rey Complex Figure Test: copy (F=20.66, p.<0.001), Immediate memory of Seoul Verbal Learning Test-Elderly's version (F=29.68, p.<0.001), delayed memory (F=45.79 p.<0.001), memory recall (F=28.97, p.<0.001), Forward of Digit Span Test (F=9.25, p=.004), backward (F=8.33, p.=0.006), language comprehension (F=13.42, p.<0.001), and digit symbol coding (F=17.74, p.<0.001) relative to the control group. Moreover depression (F=24.09, p.<0.001) was decreased in program participants, whereas self-esteem (F=40.24, p.<0.001) was increased. Conclusion: The program could be a useful intervention because the results show that the group cognitive improvement program has a significant effect on cognitive function, depression and self-esteem in elderly with mild cognitive impairment.

Purpose: This study aimed to identify depression and its predictors among Korean community-dwelling elderly with mild cognitive impairment. Methods: Secondary data analyses of the data collected by the "Study on tailored integration program for reinforcing cognitive and physical function of the frail elderly. The study used data from one-to-one interviews using structured questionnaires. The subjects were 346 community-dwelling elderly who visited a healthcare center in Seoul, Korea. A descriptive correlational study design was utilized to explore depression and its predictors including physical factors and psychosocial factors among the elderly with mild cognitive impairment. Data were analyzed using t-test, Pearson's correlation, and hierarchical regression. Results: Mean score of depression was within normal limit $11.61{\pm}6.69$. Somatic symptoms, negative life events (severity), social support were shown as significant predictors of depression. The most influential predictor for depression was somatic symptoms (${\beta}$=.340, $p$ <.001). Conclusion: To prevent and relieve depression in the elderly with mild cognitive impairment, nursing intervention strategies which consider well-balanced physical and psychosocial aspects are needed. In particular, a specific nursing intervention strategy is required to improve physical health of the elderly with mild cognitive impairment.
