Brief Summary

The aims of this study is to evaluate the effectiveness of non-pharmacological interventions program in preventing progression from mild cognitive impairment to dementia in patients with mild cognitive impairment in the short term, at Nhân dân Gia Định Hospital, Hồ Chí Minh City.

Detailed Description

A non-pharmacological interventions program in dementia prevention is highly promising because: (i) the results of using drugs (e.g. cholinesterase inhibitors) have not been successful, so non-pharmacological interventions may be a promising and risk-free alternative; (ii) people with mild cognitive impairment still maintain memory capacity that allows them to learn and apply new information and skills; (iii) interventions at an early stage of the cognitive decline process will bring maximum benefits; (iv) there is evidence that cognitive training exercises have a positive effect on cognitive decline and are one of protective factors against dementia.

Although studies on non-pharmacological prevention programs with cognitive training exercises as a key component are not uncommon, we found that there are still some unclear points. First and foremost, there has been no cognitive training exercises in Vietnamese that has been studied. Most use foreign language communication, making language-related stimuli inapplicable in Vietnam. Next, the exercise design either focuses on improving thinking and flexibility, which is more suitable for younger people, or only prioritizes impacting certain cognitive domains. Finally, many current programs are integrated as technology applications on phones, which, although convenient, are not really user-friendly for the elderly in Vietnam due to habits, operating system response delays, and equipment costs.

Primary Outcome Measures

Name	Time	Method
Effectiveness of Intervention Program	Measured at month 3 and 6 after randomisation	Evaluating the effectiveness of preventing progression from mild cognitive impairment to dementia using the Montreal Cognitive Assessment (The MoCA Test) in patients with mild cognitive impairment in the short term. Higher scores mean a better outcome. The following result ranges may indicate cognitive impairment: 18-25 points: Mild cognitive impairment. 10-17 points: Moderate cognitive impairment. Fewer than 10 points: Severe cognitive impairment.

Secondary Outcome Measures

Name	Time	Method
Change in mental health	Baseline, Week12, Week24	Evaluating improvement using Geriatric Depression Scale-15 (GDS15). Higher scores mean a worse outcome.
Change in Activities of Daily Living	Baseline, Week12, Week24	Evaluating improvement using The Lawton Instrumental Activities of Daily Living Scale (IADL). Higher scores mean a better outcome.
Patient Attendance	Week12	Attendance rate is calculated as a percentage of the number of exercise sessions completed by participants by the full amount of sessions they are expected to perform throughout the study. Not achieved \< 90%
Change in physical fitness	Baseline, Week12, Week24	Evaluating improvement using The Senior Fitness Test Kit (Chair stand test, Arm curl test, Step in place test, Up and go test). Higher scores mean a better outcome (except Up and go test).
Patient Adherance	Week12	Adherence is assessed considering the number of individuals who have accepted to participate in the study relative to the number of participants who are recruited. Low \< 80%, moderate 80-90%, high \> 90%
