WHO estimates that dementia affects around 47 million people worldwide (or roughly 5% of the world’s elderly population). It is one of the major causes of disability and dependency among older people.
Globally nearly 10 million people develop dementia each year; one new case every three seconds.
The number of people with dementia is set to triple between 2015 and 2050.
Nearly 60% of people with dementia currently live in low- and middle-income countries and most new cases (71%) are expected to occur in those countries.
In 2015, the estimated costs of dementia to society were US$ 818 billion.
This is expected to more than double by 2030, to US$ 2 trillion.
Dementia is underdiagnosed worldwide and when it is diagnosed, it is generally late in the progression of the disease.
The gap between the need for treatment and care for dementia, and the provision of these services is substantial.
Families and friends provide most of the care. Caring for someone with dementia without training and support network can be mentally and financially difficult.
Diagnostics, treatment, care and cure
There is no treatment currently available to cure dementia or to alter its progressive course.
Research involving the pharmaceutical industry, governments and academics is ongoing for better diagnostics and a cure. Many studies are ongoing and many different products are in the pipeline.
Much can be done, however, to improve the lives of people with dementia and their carers and families. The principal goals for dementia care are:
Optimizing physical health, cognition, activity and well-being
Identifying and treating accompanying physical illness
Detecting and preventing or coping with challenging behaviour
Providing information, skills training and long-term support, such as enabling them to take time out for themselves.
What WHO is doing
Developed the Global action plan on the public health response to dementia, adopted by the World Health Assembly in May this year.
The Plan provides guidance to governments, development agencies, research institutions and civil society on the development of policies on dementia across health, social and other sectors, and prevention and promotion strategies.
Establishing the Global Dementia Observatory to function as an international surveillance platform for policy-makers and researchers to facilitate and enable monitoring and sharing of information on dementia policies, service delivery, epidemiology and research. Launch is planned for the end of 2017.
Developing a Dementia Friendly Initiative Toolkit to provide practical guidance on how to assess and improve dementia-friendliness of physical and social environments.
Countries at the forefront of creating dementia-friendly communities – from local initiatives to country-wide programmes - include Australia, Japan and the UK.
The UK and Japan have agreed to take forward:
Promotion of policies on age- and dementia-friendly communities and dementia friends programmes
Creation of a network to support information sharing
Support for international joint research on the benefits and effectiveness of dementia-friendly communities and dementia friends programmes
Developing dementia risk reduction guidelines for countries to increase behaviours that can prevent or delay dementia.
Developed iSupport, www.isupportfordementia.org, an e-health solution that provides information and skills training for carers of people living with dementia. The first study of the usability and effectiveness of iSupport is currently ongoing in India.
Dementia is an umbrella term for several progressive diseases affecting memory, cognitive abilities and behaviour that interfere significantly with a person’s ability to maintain usual daily activities.
The most common types of dementia are Alzheimer’s disease and vascular dementia.
Dementia is not an inevitable consequence of ageing.
