How It Works As people's dementia progresses it becomes more and more difficult to engage in a meaningful way. The combinations of both sound and scents instantly transport people to that place, stimulating memories and conversation that would otherwise have been difficult to reach. Each Scentscape comes with four scents, four smelling jars and a 30min CD with specific sounds of a particular theme. Each CD is split into 4 different sections, which relate to the four different scents.www.active-minds.org
