IntroductionAlthough there are recommendations regarding dementia-friendly architecture, studies on design features and their impact on quality of life of patients with dementia are quasi-nonexistent. The design of the environment is one of the non-pharmacological methods in the assistance of patients with dementia.ObjectivesSetting a checklist of design principles in order to assess centers for elderly with dementia; identifying the types of centers where will be applied the checklist; implementation of the checklist and determining results of assessment.AimsOur aim is to challenge the contemporary architecture of centers for elderly to be friendly with dementia patients.MethodsAfter studying literature we built a check-list of 8 principles: providing a comfortable space and also a therapeutically environment; functionality and efficiency; flexibility and accessibility; optimal design of circulation routes in order to avoid disorientation and to reduce agitation; security and safe; aesthetics; sanitation; sustainability. We then performed a case-study on two types of settings, day care centers and respite centers, and we applied the check list on three examples: two urban Day Care Centers for patients with Alzheimer Dementia (2006, Pontevedra, Spain and 2011, Alicante, Spain) and a Respite Center (2009, Dublin, Ireland).ResultsIn general, the centers are verifying the proposed checklist. Four architectural tools were identified: light, form, colour and texture. Form is more recognizable than colour and colour more recognizable than function.ConclusionsArchitecture contributes to increase quality of life in people with dementia. The proposed checklist is a promising tool for assessing dementia-friendly design.Disclosure of interestThe authors have not supplied their declaration of competing interest.
