The key to designing for dementia is to understand the condition and how those living with dementia perceive the healthcare environment around them.
Dementia affects memory and cognitive functionality, so misinterpretation and confusion is common. Be aware of changes in floor colour as it may be perceived as a step, toilets need to contrast with the floor and surrounding walls to make them more visible, the edges of stairs should have a ‘high hue and value contrast’ to minimise falls. There is much to consider, and while it can sound technical it’s really not too complicated.
Colour differentiation plays a critical role in making sure anything important to the patient stands out and can also be used to divert residents from areas they are not supposed to access. A blue door against a blue wall is going to be ignored whereas using bold hues to identify handrails against quieter tones makes them distinctive.
Using clear contrasts in colour to mark spaces that have different uses, such as the toilet, library and dining area, is essential.
