Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Home-based cognitive training exercises

The cognitive training exercises program includes a total of 19 exercises and activities. The 19 exercises are divided into 8 groups: (1) warm up and cool down (relaxation exercise), (2) episodic memory, (3) digit span and calculation, (4) language, (5) Linking Letters \& Numbers, (6) Imagery, (7) Visuoconstructional skills, (8) linking ADL/IADL tasks.

Subjects are provided with 19 exercises and instructed to perform them at home. Home-based exercises will be assessed weekly. Subjects are provided with a logbook to track their progress with the home exercises and were given the opportunity to provide feedback, ask questions, and receive support for any difficulties encountered during the process.

All cognitive training exercises are based on the Technical Procedure Instructions issued by the Vietnamese Ministry of Health.

Group Type ACTIVE_COMPARATOR

Home-based cognitive training exercises

Intervention Type OTHER

The subjects received (i) education on lifestyle modification, (ii) home-based cognitive training exercises with physiotherapist/ physiatrist contact when needed and (iii) a physical training exercises conducted at hospital under the supervision of physiotherapist/ physiatrist (3 weekly session for 12 weeks).

This arm has a duration of 12 weeks.

Supervised cognitive training exercises

The cognitive training exercises program includes a total of 19 exercises and activities. The 19 exercises are divided into 8 groups: (1) warm up and cool down (relaxation exercise), (2) episodic memory, (3) digit span and calculation, (4) language, (5) Linking Letters \& Numbers, (6) Imagery, (7) Visuoconstructional skills, (8) linking ADL/IADL tasks.

The subjects are given exercises at the hospital under the supervision of physiotherpist/ physiatrist, and are also instructed to do the exercises at home.

Home-based exercises will be assessed weekly. Subjects are provided with a logbook to track their progress with the home exercises and were given the opportunity to provide feedback, ask questions, and receive support for any difficulties encountered during the process.
