Aging Clinical Trial
Official title:
Effects of an Integrated Intervention Program on Neurocognition in Late-Middle-Aged and Older Adults Relative to ApoE Genotypes: An ERP Study
The current project is a single-blinded, double-arm, 6-month randomized controlled trial aiming to assess the effects of a integrated intervention program on neurocognitive function with respect to event-related potential in adults aged 45-70 years. Additionally, the potential impacts of apolipoprotein epsilon-4 alleles and the brain-derived neurotrophic factor will be explored.

---|---|---|---|---|
Primary | Inhibition: Changes in Stroop test performance | The computerized Stroop test is administrated to assess participants' inhibitory function, and the changes in Stroop test performance from baseline to end of the intervention (i.e., month 6) will be examined. | 30 minutes each at the baseline and at month 6 | |
Primary | Changes in neuroelectrical activities | The neuroelectrical activities during the computerized cognitive tasks is recorded and analyzed using the Neuroscan system. Changes in the neuroelectrical activities from baseline to end of the intervention (i.e., month 6) will be examined. | 60 minutes each at baseline and at month 6 | |
Secondary | ApoE genotype | A 6 mL serum sample is drawn from the antecubital veins. Based on the genetic biomarkers (rs429358 and rs7412), participants' ApoE genotype is determined at the baseline. | 5 minutes at baseline | |
Secondary | Blood neurotrophic marker: Changes in brain-derived neurotrophic factor (BDNF) levels | A 6 mL serum sample is drawn from the antecubital veins to assess BDNF levels, and changes in BDNF levels from baseline to end of intervention (i.e., month 6) will be examined. | 5 minutes each at baseline and at month 6 | |
Secondary | Physical fitness measurements: Changes in aerobic fitness | Participants' aerobic fitness is assessed using the submaximal cycle ergometer test, and changes in aerobic fitness from baseline to end of intervention (i.e., month 6) will be examined. | 30 minutes each at baseline and at month 6 | |
Secondary | Physical fitness measurements: Changes in muscular fitness | Muscular fitness is assessed using either the push-up test/30 seconds or the chair stand test/30 seconds, and changes in muscular fitness from baseline to end of intervention (i.e., month 6) will be examined. | 15 minutes each at baseline and at month 6 | |
Secondary | Physical fitness measurements: Changes in flexibility | Flexibility is assessed using the sit-and-reach test, and changes in flexibility from baseline to end of intervention (i.e., month 6) will be examined. | 15 minutes each at baseline and at month 6 | |
Secondary | Psychosocial measures: Changes in mindfulness | Mindfulness level is assessed using the 15-items (1-6 Likert scale) Chinese version of the Mindful Attention Awareness Scale (MAAS) questionnaire. Higher mean scores of the 15 items indicate higher levels of dispositional mindfulness. Changes in mindfulness scores from baseline to end of intervention (i.e., month 6) will be examined. | 5 minutes each at baseline and at month 6 | |
Secondary | Psychosocial measures: Changes in depression | Geriatric Depression Scale (GDS-15) is utilized to assess older adults' depression levels using 15 'Yes/No' items. Scores between 5 and 9 indicate mild symptoms, and a score of 10 and above indicates moderate symptoms. Changes in depression from baseline to end of intervention (i.e., month 6) will be examined. | 5 min each at the Baseline-Assessment and at the Post-Assessment | |
Secondary | Psychosocial measures: Changes in sleeping quality | The Chinese version of the Pittsburgh Sleep Quality Index will be used to assess individual's general sleep quality over a 1-month time interval. Participants complete 9 questions, and lower scores reflect better sleep quality. Changes in sleep quality from baseline to end of intervention (i.e., month 6) will be examined. | 5 minutes each at baseline and at month 6 | |
Secondary | Psychosocial measures: Changes in health-related quality of life | Health-related quality of life via the 24-items (1-5 Likert scale) WHOQOL-OLD-Taiwan is used to measure the quality of life in older persons. The higher scores indicate better quality of life. Changes in health-related quality of life from baseline to end of intervention (i.e., month 6) will be examined. | 10 minutes each at baseline and at month 6 |
