Background: Dementia is rapidly increasing in Asia.

Aim: There has been an Asian forum to ascertain country-specific patterns of management of dementia and to investigate country-specific characteristics.

Methods: In 2009, 11 dementia experts on Alzheimer’s from Korea, Japan, mainland China, Hong Kong China, Taiwan, Singapore, Philippines, Malaysia, Indonesia, Thailand, and India were invited to participate in the survey. The 33-item questionnaire were answered; awareness of dementia, characteristics of patients with memory problems, referral, diagnosis of MCI and dementia, diagnostic tools including the high-technology device, pharmacological treatment of MCI and dementia, current issues on AD, barriers and challenges in the management of dementia. Since then, 3 surveys have been completed in 2009, 2012, and 2024.

Results: New revised research diagnostic criteria for AD needing spinal tapping and brain imaging might not be adopted for clinical practice in memory clinics in Asia. Brain imaging studies like CT, MRI, SPECT, or PET are applied for more than 75% of patients as a usual part of the diagnostic workup in Korea, Japan, mainland China, Taiwan, Singapore, Indonesia, and Thailand, while 51 ∼ 75% in Philippines and 25 ∼ 50% in Hong Kong, Malaysia, and India. Proportion of patients who continue pharmacological treatment after the initial diagnosis of dementia varies country by country varies. Most countries endorsed all approved anti- dementia drugs, but some others approved a few of them (i.e., only donepezil present in Japan, galantamine absent in China, memantine absent in Indonesia, rivastigmine absent in Thailand. Cholinesterase inhibitors are prescribed in more than 90% of patients in 6 countries (i.e. Korea, Japan, Taiwan, Singapore, Philippines, Malaysia). In other 5 countries, medications like memantine, huperzine, ginkgo biloba, vitamin E, herb medicine or others are being more frequently prescribed than in above 6 countries.

Conclusions: Well-organized and planned governmental policies about dementia, in collaboration with dementia experts and their organizations, will effectively reduce burden of dementia in Asia, where an epidemic tide of dementia is approaching.
