The Effects of Exercise-Cognitive Combined Dual-Task Program on Cognitive Function and Depression in Elderly with Mild Cognitive Impairment

Abstract

Purpose: This study was to develop and verify the effects of the exercise-cognitive combined dual-task training program on cognitive function and depression of the elderly with mild cognitive impairment (MCI). Methods: A non-equivalent control group pretest-posttest design was used. The participants were assigned into two groups: an experimental group receiving an exercise-cognitive combined dual-task (n=20) and a control group receiving a simple-task (n=18). After 8 weeks of intervention (2 days per week), the change in depression and cognitive functions were compared between the groups. Results: General cognitive function (t=-2.81, p=.011), frontal cognitive function (Z=-3.50, p＜.001), attention/working memory function (U=-2.91, p=.004), depression (t=4.96, p＜.001) of the experimental group were significantly increased than those of the control group. Conclusion: The findings of the study showed that an exercise-cognitive combined dual-task program for MCI was effective in improving general cognitive function, frontal and executive function, attention/working memory function, and reducing depression.

Changes in Depression and Stress of the Middle-Aged and Elderly through Participation in a Forest Therapy Program for Dementia Prevention

“…The KGDS is used in studies determining the depression relief effect of Gestalt group therapy on remarried elderly women (Kim and Kim, 2011), proving the depression level of the elderly with mild cognitive impairment (Kim and Song, 2019), measuring the depression level to determine the key factors that affect elderly depression (Huh and Yoo, 2002), and verifying the utility of elderly depression tests for elderly patients with cognitive impairment and their guardians (Sohn et al, 2011). The SRI-MF is used in studies verifying the relationship between elderly stress and obesity (Kim, 2018), proving the effect of body scan meditation on stress of female adults (Park.…”

“…Cognitive function and walking ability are benchmarks for assessing the degree of dementia, and dysfunction in these areas may cause depression in dementia patients (Kim & Hyun, 2013;Kim & Kim, 2015). In fact, 86.2% of dementia patients experienced depression, the most important factor influencing suicide intentions (Kim & Hyun, 2013).…”

“…In fact, 86.2% of dementia patients experienced depression, the most important factor influencing suicide intentions (Kim & Hyun, 2013). Depression also broadly aggravates decline in cognitive abilities in the brain (Kim & Kim, 2015). Thus, dementia requires multidimensional and interdisciplinary interventions, due to its complex combination of cognitive functions and emotional symptoms.…”

“…Moreover, various studies have been conducted to confirm the efficacy of single-task exercise programs such as "Otago Exercise," which includes retraining mild dementia patients in muscular strength and balance (Lee et al, 2011), exercise integrating aerobic and strength workouts (Hong, 2014), and circular task-oriented exercise (Jung & Kim, 2014). However, preceding research has shown that rather than single-task exercise, dual-task training (Kim & Kim, 2015) or multiple-task training, in which two or more tasks are performed simultaneously and continuously (Yokokawa et al, 2015) may be more effective for older adults with various problems, because performing multiple tasks shows extensive brain activation and prefrontal lobe stimulation compared to single-task performance (Al-Yahya et al, 2016).…”
