Dementia is a global health timebomb – global health expert Professor Peter Piot

7 March 2012, London

Global health expert Professor Peter Piot will announce dementia is one of the largest global health challenges and call for the condition to become a top world health priority at an international conference in London today.

Professor Piot, Director of the London School of Hygiene and Tropical Medicine, former Under-Secretary General of the United Nations and former Executive Director of UNAIDS, will take to the world stage at the opening ceremony of the Alzheimer’s Disease International (ADI) conference. He will challenge the World Health Organisation to declare dementia a health priority alongside cancer, diabetes, lung disease and heart disease. He will also call for a UN General Assembly special session on mental health and dementia, and ask world leaders to sign up to an action plan to transform millions of lives.

Professor Piot said:

‘Dementia is one of the largest neglected global health challenges of our generation, with 36 million people living with the condition today. By 2050 115 million people – almost twice the current population of the UK - will be living with dementia worldwide. What we must learn from the AIDS movement is that by investing now, we will save later. Having a global action plan to defeat dementia is the first step to making a difference to millions of people.’

The action plan proposed by ADI will call on leaders of the world’s nations to commit to the following:

  1. Invest in research and coordinate research efforts with other countries
  2. Educate the public and health practitioners to ensure they recognise the signs of dementia. Provide information, support and access to treatment to ensure people can live well with dementia
  3. Record diagnosis rates in their own countries to create an accurate picture of dementia
  4. Conduct coordinated studies on the economic and social impact of dementia
  5. Develop and share health strategies to help people reduce their risk of developing dementia.

Under Professor Piot’s leadership of UNAIDS, the organisation put AIDS on the global agenda, mobilised resources, and helped provide prevention and treatment for HIV infection worldwide.

Marc Wortmann, Executive Director at Alzheimer’s Disease International said:

'Dementia is already a pressing challenge across the world, and one that the world can no longer ignore. As the global population ages, the problem will only get bigger. What's more, over half of people with dementia live in lower and middle-income countries where there is no money to support them. Governments are not prepared to deal with this spiralling problem and they must all take action today.'

There are over 36 million people living with dementia across the world. This number is set to double every 20 years. As the brain slowly shuts down, people with dementia struggle with everyday tasks including washing, eating and going to the toilet. The global economic cost of dementia is $604 billion dollars, which makes it the equivalent of the world’s 18th largest economy.

Author Sir Terry Pratchett will also speak at the opening ceremony of the ADI conference, which will be held at London’s Excel Centre from Wednesday 07 March to Saturday 10 March. Record numbers of people with dementia will attend, alongside politicians, celebrities and scientists. The conference will feature presentations by leading scientists on groundbreaking research, and workshops led by people with dementia. For more information, visit
