In pace of the rapid growth of ageing population, the number of dementia sufferer increases steadily at the same time. It was reported that more than 425,000 Australians are affected by dementia, which becomes the second-ranked cause of death overall (Macpherson, 2018). Old age, certainly, is the main risk factor of dementia. About one-third of people aged over 85 live with dementia. The treatments for the dementia sufferer are increasingly concerned as the pharmacological approach had been found minimally effective according to many findings.
