There are four major types of anti-dementia medications approved by the Hospital Authority Drug Formulary in Hong Kong (Hospital Authority Drug Formulary, 2020, April 10; Institute of Mental Health Castle Peak Hospital, 2020), including Donepezil (Aricept), Rivastigmine (Exelon), Galantamine (Reminyl), and Memantine (Ebixa). They are commonly used in treating dementia for slowing down disease progression, maintaining functioning, deferring decline, and alleviating behavioural and emotional problems. Apart from that, other drugs may be also used to ease some distressing symptoms relating to dementia at different stages, such as depression, anxiety, sleeping disorder, and antipsychotics (Social Welfare Department, 2018).
