BACKGROUND: Spatial disorientation and declining wayfinding abilities are among the early symptoms of dementia, limiting a person\'s ability to perform activities of daily living (ADLs) independently and ultimately, perhaps leading to institutionalization. A prerequisite to maintaining residents\' quality of life in a nursing home is their ability to orient themselves within their new environment.
METHODS: The available literature on wayfinding design for people with dementia in nursing homes was reviewed. Two aspects of interventions for residents\' wayfinding abilities were identified: the design of the floor plan typology and environmental cues.
RESULTS: The design of the physical environment plays a major role in supporting the wayfinding abilities of people with dementia. The floor plan design of a nursing home in particular has a significant influence on residents\' spatial orientation and wayfinding. Additional interventions such as signage, furnishing, lighting, and colors are additional supporting features but they cannot compensate for an adverse architectural design.
CONCLUSIONS: For the creation of a supportive, dementia-friendly environment, both aspects of architectural design must be considered. Design guidelines to support the wayfinding abilities of people with dementia were developed to synthesize both.
