The cost of caring for dementia patients would be the major subject for inquiry.

The All-party Parliamentary group (APPG) on Dementia will be set to launch an inquiry to how the funds could be spent more effectively on helping those with dementia.

It is estimated that the total cost of dementia care in the UK comes to £20 billion every year and is likely to rise to around £27billion by 2018.

A report suggested that NHS had saved nearly £80 million last year by enabling people with dementia to leave hospital a week earlier.

As the number of people with dementia rises, they still would be looking into how the money could be better spent in tackling the condition this year.

Baroness Sally Greengross, chairwomen of the APPG want to share ideas and practical examples so that the NHS, local authorities and others can deliver the best care at the right price.

Researchers from the Institute of Neurology, University College of London have found that by combining lumber puncture with MRI scan of brain, they can detect the early stages of dementia.
