Introduction: Today's multicultural society has resulted in major changes, with healthcare undergoing significant modifications. Healthcare workers and patients are increasingly confronted with "cultural" backgrounds other than their own. The world's population is ageing, and the number of people with dementia is growing, resulting in a growing number of older people with a foreign background whose care needs have increased at different rates. Migration does not only mean moving from one place to another; it also involves the transition of an individual's lifestyle, life views, social and economic adjustments that may lead to certain changes. These transitions from the "old" to the "new" way of life and from a life without dementia to a life with dementia involve making sense of life's changes. Aim: The aim of study I was to explore the experiences and perceptions of dementia among Iranian staff working in a culturally profiled nursing home (CPNH). The aim of studies II and III was to explore relatives' decisions to end caregiving at home, and Iranian families' and relatives' attitudes towards CPNHs in Sweden. The aim of study (IV) was to explore how the residents with dementia at the CPNH expressed the feeling of "home". Method: This thesis is based on more than one year's fieldwork. The empirical material is based on interviews and observations. Three groups of participants were interviewed and observed: 10 people with dementia (IV), 20 family caregivers and relatives (II and III, respectively) and 34 staff members (I). The interviews were conducted in Persian/Farsi, Azerbaijani, English and Swedish. The choice of language was always up to the participants. All the interviews were audio-recorded, transcribed verbatim in the respective languages and then translated later into Swedish. The analysis of the material was based on content analysis blended with ethnography. Results: Study I shows that people from different culturally and linguistically diverse backgrounds could have different perceptions of what dementia entails. A lack of knowledge concerning dementia affects how staff approach these people. Study II shows that the CPNH is crucial when deciding to cease caregiving at home. It is important to ensure that relatives with dementia are Dementia across cultural borders 2 cared for by someone who speaks the same mother tongue. The results indicate that positive feelings of relief or comfort are dominant responses among the participants, some of whom even feel pride in the high standard of care provided by the home. In Study III, most participants based their views on a comparison between the CPNH and Iranian nursing homes after the Islamic Revolution. Negative views of the nursing home were evaluated alongside what the respondents considered to be typically Iranian. In Study IV, the results show that people with dementia's personal experiences of home played a great role, and although none of the participants felt at home, all of them stated that the CPNH was a place to live in. Conclusion: Perceptions of d...
