Objective: The purpose of this study is to conduct a preliminary research for the development of a Performance-Based Cognitive Function Test (PCFT) to screen the elderly for cognitive function impairment, and examine the reliability and validity of the test. Methods: A draft version of the Performance-Based Cognitive Function Test (PCFT) was developed and utilized in nine healthy elderly individuals. In order to verify its reliability, we analyzed the internal consistency of the PCFT. In order to verify the concurrent validity of the PCFT, this study analyzed the correlation between motor-cognitive dual task assessments and the Korean version of the Mini-Mental State Examination (MMSE-K). Results: The internal consistency of the PCFT for motor and cognitive tasks was 0.871 and 0.959 (Cronbach's ${\alpha}$), respectively. Concurrent validity of the PCFT, which was performed through motor-cognitive dual task assessments, ranged from 0.755 to 0.964 (Spearman's rho statistic, p < 0.05). In addition, correlation between the cognitive assessment tool and the MMSE-K ranged from 0.849 to 0.943 (p < 0.01). Conclusion: This study verified, and established the reliability and validity of the PCFT. Further studies are required to examine other psychometric properties in a modified PCFT, for screening cognitive function impairments in the elderly.

Imaging studies using MRI, PET, and/or MEG have been primary evaluation methods to quantitatively assess cognitive function. Recent advances in computational technology and information technology may allow a novel evaluation methodology to quantitate cognitive function more cost-effectively. In this study, we developed a software package composed of a series of tests to evaluate cognitive ability combined with a user-friendly touch screen input device. This cognitive assessment tool can quantitate concentration, numeric memory, associative memory, topological memory, visual and muscular reaction, and acoustic reaction over a relatively short testing time. We performed an empirical study on eighty normal subjects aged 20 and 59 years old using the developed evaluation methods. Age-related cognitive deterioration after 40 years old was confirmed. There was no difference in cognitive ability between male and female in the same age group. This study demonstrates the feasibility of a simple but effective evaluation software tool to quantitatively assess cognitive ability. This methodology may provide improved accessibility and reduced costs to perform cognitive function studies to compare between various subject groups.

The purpose of this study is to investigate the Effects of the Integrative Cognitive Training Program on Cognitive Function of the community elderly. Nonequivalent control group pretest-posttest design was used. 28 subjects were assigned to each of the group. 24 sessions of the integrative Cognitive Training Program were applied to the experimental group from September to December. The program was provided twice per week for 12weeks, total 24 sessons to the experimental group. Cognition scale for older adults(CSOA) was used to measure cognitive function of the groups before and after the Intervention. The score of Cognition Scale for Older Adults was significantly increased in experimental group than in control group(p< .05). The results of the study that Integrative Cognitive Training Program can be vey useful to improve the cognitive ability for the community elderly.

Objectives: The purpose of this study was to investigate whether longitudinal changes in positive and negative symptoms affect cognitive functioning in chronic schizophrenia. Methods: Sixty-eight patients diagnosed with DSM-IV schizophrenia were examined on two occasions over 6 months for symptoms and cognitive changes. Symptoms were measured by PANSS. Cognitive functions were examined for sustained attention, executive function, concentration and attention, and verbal memory and learning using Degraded Stimulus Continuous Performance Test, Wisconsin Card Sorting Test, Digit Span, and Rey Auditory Verbal Learning Test, respectively. Twenty control subjects were assessed to compare the cognitive scores of remitted schizophrenic patients. Results: Patients showed significant improvement in symptoms and all cognitive tests after 6 months treatments. Significant improvements in positive and negative symptoms did not predict improvements in any aspect of cognitive functioning measured. Normal controls performed significantly better than remitted schizophrenic patients on all cognitive tests. The results show no relationship between change in symptoms and change in cognition in chronic schizophrenia. Conclusion: We suggest that symptomatic and cognitive impairment may be a distinct construct. These findings highlight the importance of treating cognitive impairment in addition to the clinical symptoms of schizophrenia.

The purpose of this study was to analyze the relationship between social participation activities, cognitive function, and depression of middle and old single-person households in consideration of social problems such as aging population and increasing single-person households. For the analysis, path analysis and multi-group analysis were conducted. As a result of the analysis, it was found that social participation activities of middle and old single-person households reduced depression through increased cognitive function, and the positive effects of social participation activities were stronger in groups of dementia. Based on these results, we discussed ways to promote social participation activities, implications for developing programs that can help cognitive function or mental health, and suggested the need for programs or treatment methods to promote social participation rather than isolated treatment in nursing facilities.

This study was undertaken to determine the correlation between β-amyloid, serum lipid levels, and cognitive function in the elderly with mild Alzheimer's dementia. The study was conducted in December 2018, enrolling 45 elderly people with mild Alzheimer's disease. Blood analysis measured the β-amyloid and serum lipid levels, and cognitive function was measured using MMSE-K. The correlation between β-amyloid, serum lipid levels and cognitive function was determined using Pearson's correlation analysis. A significantly negative correlation was observed between the β-amyloid level and cognitive function (p<0.05). Furthermore, serum lipid levels and cognitive function also revealed a significantly negative correlation between TC and LDL levels (p<0.05). These results indicate that increasing levels of β-amyloid, TC, and LDL augments a negative correlation that decreases the cognitive function, signifying that management of pathologic factors related to dementia is important for the prevention and improvement of cognitive function in dementia patients.

This study identifies the moderating effects of cognition on the relationship between self-care confidence and self-care behavior in the diabetic elderly. The participants were 205 elderly subjects with diabetes, who visited a citizen health center located in D city, Korea. Data were collected from 20th April to 31st August 2015, and were analyzed by t-test and multiple regression. Our results reveal no significant differences between the depressive and non-depressive groups, when considering diabetes self-management confidence, knowledge, behavior and cognitive function. Cognitive function had a moderating effect in the relationship between self-care confidence and self-care behavior only in the depressed group. Our results indicate that it is therefore necessary to apply individual nursing intervention based on cognitive function and depression level, and to develop various programs for improving the cognitive function and depression amongst the diabetic elderly.
