David Cameron has set out a new, long-term strategy focused on boosting research, improving care and raising public awareness about dementia.

Britain will expand its efforts to combat dementia over the next 5 years, the Prime Minister David Cameron said today as he set out a new, long-term strategy focused on boosting research, improving care and raising public awareness about the condition.

Britain has emerged as the world leader in fighting dementia since 2010 with investment in research doubled, hundreds of thousands of NHS staff given specialist training and 1 million 'Dementia Friends' taking part in awareness sessions across the country.

The Prime Minister wants to build on that momentum both in the UK and worldwide. The Prime Minister's Challenge on Dementia 2020 is the next phase in the country's effort to combat the condition and includes:

Over £300m invested in UK research

The UK government will invest over £300 million into UK research and medical innovation, backing the country's world-leading science and medical sectors to lead the way in discovering the next big breakthrough. Annual investment in UK research is expected to double by 2025. Alongside this effort, an international dementia institute will be established in England within 5 years, helping to make the UK a world leader for research on dementia and medical trials. It is hoped the number of people taking part in dementia research will double in that time and a new online and telephone service to facilitate people taking part in dementia research studies will be launched next week.

New global fund on dementia

A separate multi-million pound fund will be launched within weeks to help establish a large-scale, international investment scheme to discover new drugs and treatment that could slow down the onset of dementia or even deliver a cure by 2025. The fund will see investors from the private, public and philanthropic sectors unite under a single scheme to finance a range of research projects identified by scientists as having the best potential for future success.

One million NHS staff trained

All NHS staff – some 1.3 million people – will now be required to undergo training in dementia so that people have the know-how and understanding to provide the best possible standards in care, from hospital porters to surgeons.

Three million more 'Dementia Friends'

A world-leading call to action on dementia will see 3 million more trained to understand about dementia and how to best support people who may have the condition. Members of the public will be able to take part in free sessions in schools, church halls or their own work places. By 2020 the majority of people in England will be living in towns and cities that have been transformed into dementia-friendly communities., making shops, transport and other public places accessible to people with dementia. Business will play its part, with M&S, Asda, Argos, Homebase and Lloyd's banking group training staff to be become Dementia Friends.

Faster assessments, better care for all

Nationally, initial dementia assessments will take place in an average of 6 weeks, followed by better support post-diagnosis. GP diagnosis rates have increased from 42% to 59% in just 3 years but too many people are waiting up to 6 months for a full assessment, causing worry and uncertainty for people and their families. This will no longer be tolerated. There will also be a greater focus on the support given to people following their diagnosis such as giving people with dementia better information about the services available locally, as well as advice and support for carers.

Announcing the plan, the Prime Minister, David Cameron, said: "Dementia is one of the greatest challenges of our lifetime, and I am proud that we are leading the world in fighting it.

Because of the growing strength of our economy, we can invest in research and drug-development, as well as public understanding, so we defeat this terrible condition and offer more hope and dignity for those who suffer.

That way, we can help make Britain a country that offers security in retirement for all."

Dementia is a growing problem. In 10 years it is expected there will be one million people living with dementia in the UK.

The Prime Minister has made it a key priority to overhaul the UK's approach to dementia, launching the Prime Minister's Challenge on Dementia in 2012, and hosting the first-ever dedicated G8 event on dementia in 2013 to secure greater global cooperation between leading nations.

Significant progress has been made in improving health and care for people with dementia and carers, creating dementia friendly communities, and boosting dementia research.
