Every three seconds, someone in the world develops dementia. With approximately 50 million people affected by dementia disease worldwide and 10 million new cases being diagnosed every year, dementia is one of the most pressing health issues facing societies across the globe today. It is estimated that 82 million people will be living with the disease in 2030 followed by 152 million in 2050. Besides affecting the patients, their families and caregivers both emotionally and financially, dementia also has a direct effect on the world’s economy. In 2018, the cost of dementia was a staggering trillion dollars, a figure that increases every day.
Dementia is not a normal part of ageing
Although dementia mainly affects older people, it is not a normal part of ageing. Dementia is a syndrome, usually of a chronic or progressive nature, caused by a variety of brain illnesses that affect memory, thinking, behaviour and ability to perform everyday activities.
Approximately 50 million people live with dementia
The total number of people with dementia worldwide is estimated to approximately 50 million. In 2018, up to 66 % of them were living in low- and middle-income countries. This figure is set to rise to 71% by 2050.
A new case of dementia is diagnosed every 3 seconds
The total number of new cases of dementia each year worldwide is nearly 10 million, implying one new case every three seconds. The number of people with dementia is expected to reach 152 million by 2050.
Huge economic impact; US$ 1 trillion per year
The high cost of the disease will challenge health systems to deal with the predicted future increase of cases. The costs are estimated at US$ 1 trillion per year at present and are set to increase even more quickly than the prevalence.
Caregivers of people with dementia experience high strain
Caring for people with dementia is overwhelming for caregivers. The stressors include physical, emotional and economic. Caregivers will require support from the health, social, financial and legal systems.
Early diagnosis improves the quality of life of people with dementia and their families
The principal goals for dementia care are:
- Diagnosing cases early
- Optimizing physical health, cognition, activity and well-being
- Detecting and treating behavioural and psychological symptoms; and
- Providing information and long-term support to caregivers.
People with dementia and their families are often discriminated against
People with dementia are frequently denied the basic rights and freedom available to others. For example, physical and chemical restraints are used extensively in aged-care facilities and acute-care settings.
Awareness and advocacy are needed
Improving the awareness and understanding of dementia across all levels of society is needed to decrease discrimination and to improve the quality of life for people with dementia and their caregivers. More research is needed to develop new and more effective treatments and to better understand the causes of dementia. Research that identifies the modifiable risk factors of dementia is still scarce.
Dementia is a public health priority
To address this important health priority there are actions that can be taken:
- Make dementia a public health and social care priority everywhere
- Improve attitudes, and understanding of dementia
- Invest in health and social systems to improve care and services for people with dementia and their caregivers; and
- Increase research on dementia.
