What is the trend of dementia in Singapore? Examining Prevalence and Projections

According to the Well-being of the Singapore Elderly (WiSE) 2023 study, the weighted prevalence of dementia among older adults is 8.8%, a non-significant decrease from 10% a decade earlier. Understanding what is the trend of dementia in Singapore is critical for healthcare planning and preparing for the demands of a rapidly aging society.

Quick Summary

Despite a decade of prevention efforts showing a stable age-specific prevalence of dementia among older adults, the total number of cases in Singapore is expected to grow significantly due to its rapidly aging population. Government initiatives focus on awareness, early diagnosis, and supporting caregivers to manage this growing public health challenge.

Key Points

• Stable Age-Specific Prevalence: Recent studies suggest the age-specific prevalence of dementia among older adults in Singapore has remained relatively stable over the past decade.

• Increasing Total Cases: Due to a rapidly aging population, the overall number of people living with dementia in Singapore is projected to rise significantly, estimated to reach 152,000 by 2030.

• Decreasing Undiagnosed Cases: The proportion of undiagnosed dementia cases has decreased substantially over the last decade, indicating improved public awareness and early help-seeking behavior.

• Protective and Risk Factors: Higher education and employment levels are associated with a reduced risk, while factors like chronic health conditions and lifestyle habits are linked to a higher risk.

• Government Initiatives: Singapore has implemented comprehensive strategies, such as Dementia-Friendly Communities and increased support for caregivers, to address the growing needs of its aging population.

• Focus on Prevention and Early Detection: The ongoing focus is on preventive care, public education, and enhancing early diagnosis through initiatives like memory clinics.

Prevalence of Dementia: A Decade of Data

From a recent nationwide study, the Well-being of the Singapore Elderly (WiSE) 2023, the weighted prevalence of dementia in Singapore among adults aged 60 and above was 8.8%. This figure is a decrease from the 10% recorded in the WiSE 2013 study, though this reduction was not statistically significant. This stability in the age-specific prevalence suggests that awareness campaigns and preventative health measures may be having a positive effect on delaying onset. However, it is crucial to interpret this finding in the context of Singapore's demographic shift towards an aging population.

Factors Influencing Prevalence Trends

The WiSE 2023 study identified several factors associated with the stable dementia prevalence. Increased education levels and higher employment rates among older adults were positively associated with the decline, suggesting protective effects. Conversely, factors like chronic health conditions (e.g., stroke) and potentially the indirect impacts of events like the COVID-19 pandemic on cognitive health introduced complexities to the trend analysis.

Future Projections and the Impact of an Aging Population

While the rate of dementia prevalence may be stabilizing, the total number of people with dementia in Singapore is expected to rise sharply. This is a direct consequence of the city-state's rapid demographic aging. Singapore is on track to become a 'super-aged society' by 2026, where over 20% of its population is aged 65 or older. Projections estimate that the number of people with dementia could increase to 152,000 by 2030. This trend is not unique to Singapore, with similar patterns seen in other aging Asian countries like Japan and South Korea.

Risk Factors and Prevention

Several modifiable and non-modifiable risk factors contribute to dementia. Public health initiatives in Singapore promote a holistic approach to reduce risk. Some key factors include:

• Non-Modifiable Factors: Age (over 65) and a family history of dementia.
• Modifiable Factors:
  • Physical Inactivity: A sedentary lifestyle is linked to a higher risk.
  • Lifestyle Diseases: Managing chronic conditions like diabetes, hypertension, and high cholesterol is crucial.
  • Mental Well-being: Depression and social isolation are associated with increased cognitive decline.
  • Diet: A healthy diet rich in fruits, vegetables, and omega-3s can be protective.
  • Hearing Loss: Untreated hearing loss is linked to a higher risk of cognitive decline.

Government Initiatives and Support Systems

The Singaporean government, through agencies like the Agency for Integrated Care (AIC) and the Ministry of Health (MOH), has implemented extensive programs to address the rising tide of dementia. These initiatives focus on awareness, early detection, and caregiver support.

1. Dementia-Friendly Singapore (DFSG): This national initiative works to build supportive networks and communities for persons with dementia and their caregivers.
2. Community Outreach Teams (CREST): These teams raise public awareness, promote early recognition, and provide emotional support and service linkages.
3. Caregiver Support: Enhanced financial assistance, training courses, and respite care options are available to support caregivers.
4. Memory Clinics: Public hospitals offer memory clinics for early assessment and diagnosis, and the number of these is increasing.

Comparing Dementia Trends: Singapore vs. Global Context

Understanding Singapore's trend requires a look at international data. While some Western countries have seen a decrease in age-specific dementia prevalence, other Asian nations mirror Singapore's challenge with rising total case numbers due to aging populations.

Indicator	Singapore (WiSE 2023)	Japan (Nakahori et al., 2021)	South Korea (Shin, 2022)
Age 60+ Prevalence	8.8%	15.7% (2014)	9.95% (2016, 65+)
Undiagnosed Cases	51.5%	N/A	N/A
Projection by 2030	152,000 cases	N/A	N/A
Key Context	Population aging drives total case increase	Prevalence increasing with aging	Prevalence increasing with aging

Conclusion: Looking Ahead

What is the trend of dementia in Singapore? It is a complex picture of stabilization in age-specific prevalence, likely aided by health promotion and awareness efforts, set against the backdrop of a significant increase in the total number of individuals with the condition. This growing demand on the healthcare system and families underscores the importance of continued investment in preventive programs, early diagnosis, and robust support systems.

Frequently Asked Questions

What is the primary factor driving the increase in total dementia cases in Singapore?

The main factor is Singapore's rapidly aging population. Although the rate of dementia among older adults has been relatively stable, the sheer increase in the number of seniors means the total number of cases will rise.

How do Singapore's dementia trends compare to other countries?

While some Western countries have seen a decrease in age-specific dementia prevalence, many other Asian countries with aging populations, like Japan and South Korea, are seeing similar increases in overall dementia cases, mirroring Singapore's situation.

What are some of the modifiable risk factors for dementia in Singapore?

Modifiable risk factors include physical inactivity, uncontrolled lifestyle diseases (hypertension, diabetes), depression, social isolation, and an unhealthy diet. Addressing these can help reduce or delay the onset of dementia.

What is a 'Dementia-Friendly Community' in Singapore?

A Dementia-Friendly Community is a national initiative (DFSG) aimed at building supportive networks for people with dementia. It involves public awareness campaigns, establishing 'Go-To Points' for assistance, and equipping the public with knowledge to help those with dementia.

Where can caregivers of people with dementia find support in Singapore?

Caregivers can find support through various government and non-profit channels. This includes support groups, specialized community outreach teams (CREST-Caregivers), respite care services, and financial assistance schemes like the Home Caregiving Grant.

Has the rate of undiagnosed dementia changed in Singapore?

Yes, studies have shown a significant decrease in the proportion of undiagnosed dementia cases over the last decade. This is attributed to increased public awareness and better access to memory clinics.

Are there financial subsidies available for dementia care in Singapore?

Yes, the Singapore government offers various subsidies. These include means-tested subsidies for hospital care, schemes like CHAS for outpatient treatment, and grants to help with caregiving expenses.
