Dementia victims to triple in 30 years: WHO

GENEVA, 9 days ago

As the global population ages, the number of people living with dementia is expected to triple from 50 million to 152 million by 2050, said the World Health Organisation (WHO).

"Nearly 10 million people develop dementia each year, six million of them in low- and middle-income countries," said Dr Tedros Adhanom Ghebreyesus, director-general of WHO. "The suffering that results is enormous. This is an alarm call: we must pay greater attention to this growing challenge and ensure that all people living with dementia, wherever they live, get the care that they need."

The estimated annual global cost of dementia is $818 billion, equivalent to more than 1 per cent of global gross domestic product. The total cost includes direct medical costs, social care and informal care (loss of income of carers). By 2030, the cost is expected to have more than doubled, to $2 trillion, a cost that could undermine social and economic development and overwhelm health and social services, including long-term care systems.

First global monitoring system launched

The Global Dementia Observatory, a web-based platform launched by WHO today, will track progress on the provision of services for people with dementia and for those who care for them, both within countries and globally. It will monitor the presence of national policy and plans, risk reduction measures and infrastructure for providing care and treatment. Information on surveillance systems and disease burden data is also included.

"This is the first global monitoring system for dementia that includes such a comprehensive range of data," said Dr Tarun Dua, of WHO’s Department of Mental Health and Substance Abuse. "The system will not only enable us to track progress, but just as importantly, to identify areas where future efforts are most needed."

To date, WHO has collected data from 21 countries of all income levels. By the end of 2018, it is expected that 50 countries will be contributing data.

Initial results indicate that a high proportion of countries submitting data are already taking action in areas such as planning, dementia awareness and dementia-friendliness (such as facilitating participation in community activities and tackling the stigmatization of people living with dementia) and provision of support and training for carers, who are very often family members.

Of the countries reporting data so far:

•    81 per cent have carried out a dementia awareness or risk reduction campaign
•    71 per cent have a plan for dementia
•    71 per cent provide support and training for carers
•    66 per cent have a dementia-friendly initiative.

All of these activities are recommended by WHO in the Global action plan on the public health response to dementia 2017-2025. The Plan provides a comprehensive blueprint for action, in areas including: dementia awareness and dementia-friendliness; reducing the risk of dementia; diagnosis, treatment and care; research and innovation; and support for dementia carers.

It suggests concrete actions that can be taken by policy-makers, health- and social-care providers, civil society organizations and people with dementia and their careers. The Plan has been developed with attention to the importance of respecting the human rights of people with dementia and engaging them in planning for their care. Targets against which progress can be measured are included.

Diagnosis and research require significant effort

Just 14 per cent of countries reporting data could indicate the number of people being diagnosed with dementia. Previous studies suggest that as many as 90 per cent of people with dementia in low- and middle-income countries are unaware of their status.

The data also highlight the need for rapid scale-up of research. There have been some encouraging signs in funding available for investment in research for a cure for dementia in recent years, but much more needs to be done. The number of articles in peer-reviewed journals on dementia in 2016 was close to 7,000. This compares with more than 15,000 for diabetes, and more than 99,000 for cancer during the same year. Research is needed not only to find a cure for dementia, but also in the areas of prevention, risk reduction, diagnosis, treatment and care.

The Observatory will provide a knowledge bank where health and social care authorities, medical professionals, researchers and civil society organizations will be able to find country and regional dementia profiles, global reports, policy guidance, guidelines and toolkits on dementia prevention and care.

Dementia

Dementia is an umbrella term for several diseases that are mostly progressive, affecting memory, other cognitive abilities and behaviour and interfering significantly with a person’s ability to maintain the activities of daily living. Women are more often affected than men. Alzheimer’s disease is the most common type of dementia and accounts for 60–70 per cent of cases. The other common types are vascular dementia and mixed forms. – TradeArabia News Service
