Brief Summary

Evidence showed that both TENS and passive body heating are potential treatment strategies for improving cognitive functions in people with dementia. It is hypothesized that hat device (Warmth +TENS) over the 4 acupuncture points would induce a greater improvement in cognitive functions and behavioural symptoms when compared with other hat devices (Warmth + placebo-TENS; TENS only; Warmth alone) and Control (hat device with no warmth and no TENS).

Detailed Description

Acupuncture, a primary therapeutic method in traditional Chinese medicine, has been used for patients with dementia to improve memory, orientation, calculation, and self-managing ability in patients having dementia and prevent decline of cognitive functions. Results of animal studies have demonstrated that electroacupuncture on the head region is effective in managing the symptoms associated with dementia, including vascular dementia.

A review of 8 studies on effects of TENS on non-pain related cognitive and behavioural functioning in patients with Alzheimer's disease and non-demented patients concluded that TENS could improve memory, affective behaviour and rest-activity rhythm in patients having Alzheimer's disease.

Passive body heating is another novel physical intervention strategy which potentially can relieve the symptoms of dementia. A previous study demonstrated that the attention function of 15 elderly, measured by the reaction time in the Rapid Visual Processing Test, improved after passive body heating via a thermal suit. Moreover, 30 minutes of hot-water immersion improved the sleep quality in 13 people with vascular dementia.

Primary Outcome Measures
NameTimeMethod
The Hong Kong version of Montreal Cognitive Assessment (HK-MoCA) - BaselineBaseline (0 week)

The HK-MoCA will be used to assess the level of cognitive impairment. The scores of HK-MoCA ranging from 0 to 30, with a higher score indicates a higher level of cognitive function. This instrument was designed to evaluate 7 domains of cognitive functions which are key determinants of the functional performance of the participants, namely visuospatial/executive functions, naming, verbal memory registration and learning, attention, abstraction, delayed verbal memory.

Secondary Outcome Measures
NameTimeMethod
Chinese version of Disability Assessment for Dementia (C-DAD) - long term followup62 weeks

C-DAD will be used to assess the participant's ability to perform a spectrum of functional activities, such as going on an outing and housekeeping. During the assessment, a caregiver is asked to indicate if the participant was able to perform 47 daily activities within the previous weeks with the responses of 'yes', ''no' or 'not applicable'. The result will then be converted into a scale ranging from 0 to 100, with a higher score indicates a higher level of functioning.
