“…Each question was measured on a 4-point Likert scale, with total scores ranging from 0 to 27. The depressive symptoms were classified into five levels: minimal (0-4), mild (5-9), moderate (10)(11)(12)(13)(14), moderately severe (15)(16)(17)(18)(19), and severe (20)(21)(22)(23)(24)(25)(26)(27). In this study, the Cronbach's alpha of the PHQ-9 was 0.803.…”

“…According to the results of previous studies, age, education level, and degree of depression had an effect on mild cognitive impairment [12] and subjective cognitive decline in older adults [13,14]. In addition, activity ability, diabetes, smoking, exercise, subjective health status, and social relationships affected cognitive decline [15][16][17].…”

The purpose of this study was to identify the factors affecting subjective cognitive impairment. We analyzed data from the 2019 Korea Community Health Survey and enrolled 68,546 middle-aged adults, aged 50 to 64 years, and 74,547 older adults, aged 65 years and older, in this study. Multiple logistic regression analysis was performed to identify factors influencing subjective cognitive impairment. Of the participants, 11,926 (17.4%) middle-aged and 21,880 (29.4%) older adults living in the community reported subjective cognitive impairment. Major factors that influenced subjective cognitive impairment in both middle-aged and older adults were gender, subjective stress, depressive symptoms, and alcohol drinking. In contrast to middle-aged adults, the marital status of older adults affected subjective cognitive impairment. Therefore, the factors affecting subjective cognitive impairment in middle-aged and older adults need to be considered for screening and management to prevent cognitive impairment and dementia. In particular, it is necessary to evaluate and manage stress and depressive symptoms from middle age to prevent subjective cognitive impairment.

Based on the secondary data analysis, this study aimed to identify quality of life and factors that affect quality of life among Korean elderly with mild cognitive impairment. Demographic characteristics, physical factors, and psychosocial factors as well as quality of life of the elderly with mild cognitive impairment were comprehensively measured. The research subjects consisted of 348 home-resident elderly and their quality of life scores were relatively high at 29.86. Their quality of life varied according to education and gender, and instrumental activities of daily living (actual, latent), somatic symptoms, sleep quality, depression, and social support affected their quality of life. Depression and social support were predictors of quality of life. The most powerful predictor was depression (β = -.583, p < .001). To improve the quality of life among elderly with mild cognitive impairment, nursing interventions to alleviate depression and to enhance social support from family, friends, and relevant neighbors are needed.

PURPOSE The purpose of this study was to examine the effects of an eye movement exercise intervention on cognitive function and prefrontal cortex connectivity in the elderly with mild cognitive impairment.METHODS Ten older adults with mild cognitive impairment participated in eye movement exercise consisting of saccadic eye movement, pursuit eye movement, vestibular-ocular eye movement, and vergence eye movement for 4 weeks. Cognitive function (MoCA-K), reaction time during stroop task, and prefrontal cortex connectivity were measured using the functional near-infrared spectrometric analyzer (fNIRS) before and after the intervention.RESULTS First, cognitive function of the elderly with mild cognitive impairment showed significant improvement after the eye movement exercise (p < .05). Second, reaction time decreased significantly from 1.16 to 0.91 ms after eye movement exercise. Third, the strength of prefrontal cortex connectivity (left OFC - right FPC, right OFC - right FPC) increased after the intervention in the older adults with mild cognitive impairment.CONCLUSIONS The results of this study suggest that eye movement exercise is an effective intervention for improving cognitive function through improvement of brain functional connection in the elderly patients with mild cognitive impairment.
