A multidisciplinary Japan–UK Network identified cross-cultural and cross-national lessons for research aimed at improving the design of homes for people living with dementia. Previous research has suggested that improved, multidimensionally sustainable design may improve quality of life for people living with dementia and meet societal challenges of increasing populations of people with the condition. Adopting a social citizenship perspective, the paper argues that people living with dementia are considered equal citizens with rights to enjoy the life they choose. On this basis, research on home design must be underpinned by understanding the concept of home. The definition of good outcomes should be led by people living with dementia. Conceptualisation of costs of design innovations is complex and will involve judgements from a societal perspective. Methodologically, an ethnographic approach is desirable, underpinned by co-production. These points are suggested to inform further research. In conclusion, the paper confirms the value of cross-cultural insights.

Management of Behavioral and Psychological Symptoms of Dementia (BPSD) is a key challenge in geriatric dementia care. A multimodal comprehensive care methodology, Humanitude, with eye contact, verbal communication, and touch as its elements, was provided to three geriatric dementia patients for whom conventional nursing care failed in an acute care hospital. Each episode was evaluated by video analysis. All patients had advanced dementia with BPSD. Failure of care was identified by patient’s shouting, screaming, or abrupt movements of limbs. In this case series, conventional care failed for all three patients. Each element of care communication was much shorter than in Humanitude care, which was accepted by the patients. The average of the elements performed during the care was eye contact 0.6%, verbal communication 15.7%, and touch 0.1% in conventional care and 12.5%, 54.8%, and 44.5% in Humanitude care, respectively. The duration of aggressive behavior of each patient during care was 25.0%, 25.4%, and 66.3% in conventional care and 0%, 0%, and 0.3% in Humanitude, respectively. In our case series, conventional care was provided by less eye contact, verbal communication, and touch. The multimodal comprehensive care approach, Humanitude, decreased BPSD and showed success by patients’ acceptance of care.
