Eligibility
Key inclusion criteria
Community-living older adults aged 60 years and above will be screened using Chinese version of the Mini-Mental State Examination (CMMSE). Those who score between 13 and 23 will be further clinically adjudicated by a panel of clinical experts. Criteria for a diagnosis of dementia will be based on the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). Severity of dementia will be determined using Clinical Dementia Rating (CDR). Only subjects with mild to moderate dementia (CDR 1 or 2) will be invited to participate.
Minimum age
60 Years
Maximum age
No limit
Gender
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Subjects will be excluded if they have medical conditions severe enough to affect the patient’s ability to complete the treatment course and/or follow-up.

Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
This is a single blind randomized controlled trial. After eligibility check, subjects and their carergivers who agree to join the study will be randomly allocated into either the control or intervention group. Simple randomization will be adopted using computer-generated random numbers, sealed in an opaque envelope. Treatment assignment will be done by an independent person by opening the envelopes with consecutive numbers for eligible subjects. Subjects and their carergivers will aware of the treatment assigned. The outcome assessors will remain blinded to treatment allocation until the data entry is complete.

Summary
Brief summary
With the substantial increase of dementia in older adults, computer assisted intervention using touch-screen video game technology would be a novel and potential alternative intervention for older people with mild to moderate dementia in enhancing cognitive function and reducing behavioural and psychological symptoms, therefore reducing nursing / healthcare worker loads. The information obtained will promote the awareness to health professionals that touch-screen video game training is a useful cognitive and behaviour intervention in older people with mild to moderate dementia and could be incorporated as part of routine programs amongst the elderly in both community care and hospital settings in Hong Kong.
