The aim of the study was to generate design criteria in order to encourage and facilitate wayfinding for advanced Alzheimer’s patients. Two sources of data were used: interviews with the staff of a typical urban nursing home, and a wayfinding experience with its residents. The results show that even patients with severe cognitive deterioration are able to reach certain destinations. Wayfinding decisions have to be based on environmental information that is readily accessible, so that the patient can proceed from decision point to decision point. Monotony of architectural composition and the lack of reference points render wayfinding difficult. The elevators are seen to be a major anxiety-causing barrier. Visual access to the main destinations increases their use and facilitates wayfinding. Signage has an important function, creating redundancy in wayfinding communication and compensating for the loss of memory and spatial understanding. Floor patterns and dark lines or surfaces can disorient the patients and cause anxiety.
