Prime minister David Cameron has stated attending a recent Dementia Friends session gave him a "lightbulb moment" regarding what it is like to live with the condition.
The programme, which is an initiative by the Alzheimer's Society and funded by the government, sees members of the public trained in how to help individuals affected by dementia.
Mr Cameron took part in an exercise where he had to lay out the steps involved in making a cup of tea in detail, as this is designed to show how complex even everyday tasks can be.
"If more of the interactions someone with dementia has are with people with a better understanding, they will have a better quality of life," the prime minister was quoted as saying by the Daily Mail.
Some 200 sessions are being planned around the country, with thousands of people being trained by the Alzheimer's Society in dealing with people affected by dementia.
According to the NHS, Alzheimer's disease, which is the most common form of dementia, usually affects people over 65 years of age.
