This study is designed to evaluate the preliminary effectiveness and safety of a digitally based multidomain intervention in patients with MCI. In addition, a portion of cognitively normal subjects and caregivers of patients with MCI will also be recruited as an exploratory cohort. We hope that the digital platform will improve the overall cognition and quality of life in patients with MCI.

3 groups of participants will be recruited. For the participants in the MCI (group A) and cognitively normal subjects (group B), they will be provided with a digital tablet and a wearable device. The digital tablet will be pre-loaded with 10 modules, 1 module per week (1 hour) for 10 weeks to be completed at home. The wearable device will be used to track and collect physiological data.

For the caregivers of the patients with MCI (group C), they will be asked to complete a questionnaire during screening visit and follow-up visit, and to use the caregiver app during the intervention period.

Patients with MCI Thirty (30) patients with MCI of the amnestic type (single or multi domain) will be recruited. MCI will be diagnosed using the Petersen's criteria and/or the NIA-AA criteria by cognitive neurologists.

1. Either male or female aged between 50 and 70 years (inclusive)
2. Diagnosis of amnestic MCI using the Petersen's criteria and/or the NIA-AA criteria

7. Willing to give informed consent

Exclusion criteria:

1. Significant hearing or visual impairment

Cognitively Normal Subjects Ten (10) cognitively normal subjects will be recruited.

Inclusion criteria:

1. Either male or female aged between 50 and 70 years (inclusive)
2. CDR of 0 and MMSE > 27

Caregivers of Patients with MCI Fifteen (15) caregivers of the 30 patients with MCI will be recruited.

Inclusion criteria:

1. Either male or female aged ≥21 years
2. Is the spouse or child of the patient and must spend at least 2 hours per week with the patient.
