Cameron's announcement is part of the Government's plans to raise awareness of the condition that affects nearly 700,000 people and help people to spot the signs of illness and help sufferers.
Willie Cruickshank, director at Norfolk & Suffolk Dementia Alliance told HR magazine that employers should train staff about the condition as doing so can bring significant business benefits. "With a significant proportion of the population suffering from dementia, employers must realise that these are customers," he said. "Training your staff to deal with and recognise the signs is vitally important."
According to the Norfolk and Suffolk Dementia Alliance the cost of caring for people with dementia is estimated to be £23 billion a year.
The Government is launching the Dementia Friends Scheme, which has been adapted from a similar programme in Japan that recruited three million volunteers.
Cameron said: "We cannot underestimate the challenge we face in dealing with dementia in our country."
Sarah Frame, director at learning solutions provider Toolwire said: "Enabling workers to experience these issues first-hand allows them to more fully understand complex issues and determine a more positive outcome through their own actions."
