The four major types of anti-dementia medications are special drugs that are available as generics in the Hospital Authority (HA) in Hong Kong. They are prescribed by specialists for dementia patients who have been assessed as having specified clinical conditions and therapeutic needs. For dementia patients who do not have the specified clinical conditions, they must only purchase these drugs with a prescription in HA pharmacies or community pharmacies as self-financed items (Hospital Authority Drug Formulary, 2020, February 8; The Government of the Hong Kong SAR, 2015, February 25).
