Evidence-Based Wayfinding for Dementia Care
Effective wayfinding in dementia care is grounded in research, not guesswork. This article reviews the evidence base for sign placement, environmental cues, and navigation systems that genuinely help residents find their way independently.
Wayfinding -- the process of navigating from one place to another -- is one of the earliest abilities affected by dementia. Research consistently shows that environmental design can either compensate for or exacerbate wayfinding difficulties. The evidence base for dementia-friendly wayfinding has grown substantially over the past two decades, led by institutions including the Dementia Services Development Centre (DSDC), the University of Worcester Association for Dementia Studies, and the Karolinska Institute in Sweden.
How Dementia Affects Navigation#
Spatial navigation relies on several cognitive functions that dementia progressively impairs. Allocentric navigation (using an internal mental map) declines early, forcing reliance on egocentric navigation (following visible cues in the immediate environment). This shift means that signage and environmental cues become not merely helpful but essential. Without visible, meaningful cues at every decision point, residents with dementia cannot navigate independently.
Key findings from wayfinding research in dementia care settings:
- Residents rely on visible landmarks rather than memorised routes after early-stage dementia
- Realistic photographic images on signs are recognised 40% more accurately than abstract icons
- Colour contrast between sign and wall is more important than sign size
- Consistency of sign design across a building improves recognition speed by up to 60%
- Signs placed at decision points (junctions) have 3x the impact of signs placed mid-corridor
- Multi-sensory cues (visual + tactile) improve wayfinding success rates compared to visual-only cues
- Familiar domestic imagery (wooden frames, home-like fonts) reduces institutional anxiety
The Landmark Theory of Wayfinding#
Landmark theory, developed by environmental psychologists, suggests that people navigate by moving between recognisable reference points rather than following a continuous path. In a care home, these landmarks can be created deliberately: a distinctive sign at the corridor entrance, a different wall colour at a junction, a recognisable artwork beside the dining room. Signs are the most reliable and cost-effective landmarks because they can be designed to be universally recognisable and placed at precisely the right decision points.
Pro Tip
Audit your care home for unintentional negative landmarks -- features that confuse rather than orient. Common culprits include mirrors at corridor ends (which create the illusion of a continuing corridor), fire doors that block sight lines, and identical-looking corridors with no distinguishing features.
Progressive Disclosure in Sign Systems#
Progressive disclosure is the principle of revealing information at the point where it is needed, rather than overwhelming the user with everything at once. In wayfinding terms, this means a directional sign at the main corridor shows only the next destination (e.g., "Dining Room with left arrow"), not every room in the building. As the resident follows the arrow, subsequent signs provide the next piece of information. Each sign answers only the question the resident has at that moment: "Which way now?"
The strongest evidence for progressive disclosure comes from hospital wayfinding studies, but the principle applies directly to care homes. Reducing the information load at each decision point decreases cognitive demand and increases navigation success rates.

Our DSDC 1A-accredited signs are designed with progressive disclosure in mind. Door signs provide detailed room information, projecting signs offer corridor-level guidance, and directional signs deliver junction-level navigation cues. Together they create a layered system supported by the evidence base.
Evidence-based wayfinding is not about installing more signs -- it is about installing the right signs in the right places, designed in the right way. The research is clear: a well-designed sign system is one of the most effective environmental interventions available in dementia care.
