Statistical Data of Dementia in the Asia Pacific Region

News Source: Alzheimer’s Disease International Report 2014

The 18 member associations of ADI in the Asia Pacific region are located in Australia, Bangladesh, China, Chinese Taipei, Hong Kong SAR, India, Indonesia, Japan, Macau SAR, Malaysia, Nepal, New Zealand, Pakistan, The Philippines, Singapore, Republic of Korea, Sri Lanka and Thailand. The APRO is based in Singapore. There are 21 other countries or territories in the region that either do not have Alzheimer associations or are not members of ADI. The population of the Asia Pacific region is estimated as 4 billion people based on ADI’s categorization of the region. Accordingly, estimates show that the population over 60 years in the region is estimated at more than 11%. It is expected that in 2050 a quarter of the total population in the Asia Pacific region will be aged 60 years or older. The increase in ageing also extends to the oldest-old or those aged 80 and over. The proportion of the oldest-old in the Asia Pacific region has increased dramatically; in 1990, the proportion of those aged 80 years and over was 0.8% which rose to 1.4% in 2012 with projections indicating this will increase to 4.4% by 2050

Prevalence in the Asia Pacific region

Prevalence refers to the percentage of people with dementia in a population at a given point in time or over a certain time period. International epidemiological studies make it clear that dementia occurs in every country of the world. The results of prevalence studies conducted globally vary due to the differing methods employed by researchers. However, all studies have shown a rise in the prevalence rates with age. Although dementia can occur at any age, it is rare for people under the age of 60 years to be affected. As the global population continues to age, there will be relatively more people in the age groups most at risk of dementia. In the absence of effective prevention and treatment, the increase in the number of people with dementia will come about as a simple consequence of an increase in the size of the population most at risk i.e. those aged 60 years and over. In 2013, ADI adjusted its prevalence estimates due to the availability of further data from several countries. Globally, the estimated number of people with dementia in 2013was 44 million. By 2030 there will be 76 million people with dementia and 135 million by 2050. In the Asia Pacific Region, the number of people with dementia will increase from 23 million in 2015 to almost 71 million by 2050. That means by 2050 more than half of the people with dementia worldwide (135 million) will live in this region.

The Table above summarizes the prevalence and number of people with dementia in individual countries of the Asia Pacific region.
