Long-term care use, hospitalizations and mortality during COVID-19 in Finland and Sweden: A nationwide register-based study in 2020.

AIM: To describe long-term care (LTC) use in Finland and Sweden in 2020, by reporting residential entry and exit patterns including hospital admissions and mortality, compared with the 2018-2019 period and community-living individuals. METHODS: From national registers in Finland and Sweden, all individuals 70+ were included. Using the Finnish and Swedish study populations in January 2018 as the standard population, we reported changes in sex- and age-standardized monthly rates of entry into and exit from LTC facilities, mortality and hospital admission among LTC residents and community-living individuals in 2020. RESULTS: Around 850,000 Finns and 1.4 million Swedes 70+ were included. LTC use decreased in both countries from 2018 to 2020. In the first wave (March/April 2020), Finland experienced a decrease in LTC entry rates and an increase in LTC exit rates, both more marked than Sweden. This was largely due to short-term movements. Mortality rates peaked in April and December 2020 for LTC residents in Finland, while mortality peaked for both community-living individuals and LTC residents in Sweden. A decrease in hospital admissions from LTC facilities occurred in April 2020 and was less marked in Finland versus Sweden. CONCLUSIONS: During the first wave of the pandemic mortality was consistently higher in Sweden. We also found a larger decrease in LTC use and, among LTC residents, a smaller decrease in hospital admissions in Finland than in Sweden. This study calls for assessing the health consequences of the differences observed between these two Scandinavian countries as part of the lessons from the COVID-19 pandemic.

Dementia-related disability in the population aged 90 years and over: differences over time and the role of comorbidity in the vitality 90 + study.

BACKGROUND: The burden of dementia, multimorbidity, and disability is high in the oldest old. However, the contribution of dementia and comorbidities to functional ability in this age group remains unclear. We examined the combined effects of dementia and comorbidities on ADL and mobility disability and differences between dementia-related disability between 2001, 2010, and 2018. METHODS: Our data came from three repeated cross-sectional surveys in the population aged 90 + in the Finnish Vitality 90 + Study. The associations of dementia with disability and the combined effects of dementia and comorbidity on disability adjusted for age, gender, occupational class, number of chronic conditions, and study year were determined by generalized estimating equations. An interaction term was calculated to assess differences in the effects of dementia on disability over time. RESULTS: In people with dementia, the odds of ADL disability were almost five-fold compared to people with three other diseases but no dementia. Among those with dementia, comorbidities did not increase ADL disability but did increase mobility disability. Differences in disability between people with and without dementia were greater in 2010 and 2018 than in 2001. CONCLUSION: We found a widening gap in disability between people with and without dementia over time as functional ability improved mainly in people without dementia. Dementia was the main driver of disability and among those with dementia, comorbidities were associated with mobility disability but not with ADL disability. These results imply the need for strategies to maintain functioning and for clinical updates, rehabilitative services, care planning, and capacity building among care providers.

Disturbed intramitochondrial phosphatidic acid transport impairs cellular stress signaling.

Lipid transfer proteins of the Ups1/PRELID1 family facilitate the transport of phospholipids across the intermembrane space of mitochondria in a lipid-specific manner. Heterodimeric complexes of yeast Ups1/Mdm35 or human PRELID1/TRIAP1 shuttle phosphatidic acid (PA) mainly synthesized in the endoplasmic reticulum (ER) to the inner membrane, where it is converted to cardiolipin (CL), the signature phospholipid of mitochondria. Loss of Ups1/PRELID1 proteins impairs the accumulation of CL and broadly affects mitochondrial structure and function. Unexpectedly and unlike yeast cells lacking the CL synthase Crd1, Ups1-deficient yeast cells exhibit glycolytic growth defects, pointing to functions of Ups1-mediated PA transfer beyond CL synthesis. Here, we show that the disturbed intramitochondrial transport of PA in ups1Δ cells leads to altered unfolded protein response (UPR) and mTORC1 signaling, independent of disturbances in CL synthesis. The impaired flux of PA into mitochondria is associated with the increased synthesis of phosphatidylcholine and a reduced phosphatidylethanolamine/phosphatidylcholine ratio in the ER of ups1Δ cells which suppresses the UPR. Moreover, we observed inhibition of target of rapamycin complex 1 (TORC1) signaling in these cells. Activation of either UPR by ER protein stress or of TORC1 signaling by disruption of its negative regulator, the Seh1-associated complex inhibiting TORC1 complex, increased cytosolic protein synthesis, and restored glycolytic growth of ups1Δ cells. These results demonstrate that PA influx into mitochondria is required to preserve ER membrane homeostasis and that its disturbance is associated with impaired glycolytic growth and cellular stress signaling.

Unmet care needs are common among community-dwelling older people with memory problems in Finland.

Aims: Ageing in place has become a policy priority. Consequently, residential care has been reduced, and more older people with multiple care needs reside at home with the help of informal care and home care services. An increasing share of these people has memory disorders. We examined the extent to which memory problems, in addition to other individual characteristics, are associated with unmet care needs among community-dwelling older people. Methods: The study employed cross-sectional survey data from community-dwelling people aged 75+ collected in 2010 and 2015, analysed using binary logistic regression analysis. The study population consisted of people who had long-term illnesses or disabilities that limited their everyday activities (N = 1928). Nine per cent reported substantial memory problems. Of these, 35.7% had a proxy respondent. Results: People with memory problems have more care needs than those with other types of disability or illness. They receive more care but still have more unmet needs than others. About a quarter of people with memory problems reported that they did not receive enough help. This result did not change significantly when the proxy responses were excluded. Even a combination of informal and formal home care was insufficient to meet their needs. Conclusions: Insufficient care for people with memory problems implies a serious demand for further development of home care services. The care needs of this population are often complex. Unmet needs represent a serious risk to the well-being of people with memory disorders, and may also create an extensive burden on their informal caregivers.

Comorbidities in dementia during the last years of life: a register study of patterns and time differences in Finland.

BACKGROUND: Comorbidities have major implications for the care of people with dementia. AIM: To investigate the patterns of comorbidities in dementia in the last five years of life and how these patterns differed between three cohorts. METHODS: The study included people who died at age 70 and above in 2001 (n = 13,717), 2007 (n = 34,750) and 2013 (n = 38,087) in Finland. ICD-10 morbidity data for a five-year period prior to death were extracted from national registers. Principal component analysis was employed to identify patterns for several morbidities. The associations of principal component scores with dementia were analysed using binary logistic regression. Linear regression was used to examine changes in the number of morbidities in patterns over time. RESULTS: The morbidity patterns identified in the last years of life were (1) cardiometabolic disorders, (2) neurological, (3) cerebrovascular diseases and (4) musculoskeletal, thyroid and psychiatric disorders. Among the patterns, neurological and musculoskeletal, thyroid and psychiatric disorders were associated with dementia. The number of diagnoses in the cerebrovascular pattern increased and those in the musculoskeletal, thyroid and psychiatric pattern decreased over time. DISCUSSION: Comorbidity patterns identified in this nationwide register study are largely in line with previous evidence. Time difference in these patterns provide crucial information for service planning. CONCLUSIONS: Comorbidities in dementia in the last years of life occur in patterns and change over time. More systematic monitoring and updated clinical guidelines are needed for the care of comorbidities with dementia.

Place of death among older people in Finland and Norway.

Aims: This study aimed to find out how place of death varied between countries with different health and social service systems. This was done by investigating typical groups (concerning age, sex and end-of-life trajectory) of older people dying in different places in Finland and Norway. Methods: The data were derived from national registers. All those who died in Finland or Norway at the age of ⩾70 years in 2011 were included. Place of death was analysed by age, sex, end-of-life trajectory and degree of urbanisation of the municipality of residence. Two-proportion z-tests were performed to test the differences between the countries. Multinomial logistic regression analyses were performed separately for both countries to find the factors associated with place of death. Results: The data consisted of 68,433 individuals. Deaths occurred most commonly in health centres in Finland and in nursing homes in Norway. Deaths in hospital were more common in Norway than they were in Finland. In both countries, deaths in hospital were more common among younger people and men. Deaths in nursing homes were commonest among frail older people, while most of those who had a terminal illness died in health centres in Finland and in nursing homes in Norway. Conclusions: Both Finland and Norway have a relatively low share of hospital deaths among older people. Both countries have developed alternatives to end-of-life care in hospital, allowing for spending the last days or weeks of life closer to home. In Finland, health centres play a key role in end-of-life care, while in Norway nursing homes serve this role.

Ageing populations in the Nordic countries: Mortality and longevity from 1990 to 2014.

Aims: Cross-country comparisons of mortality and longevity patterns of Nordic populations could contribute with novel insights into the compositional changes of these populations. We investigated three metrics of population ageing: the proportion of the population aged 75+ and 90+ years, the proportion of birth cohorts reaching 75 and 90 years, and life expectancy (LE) at age 75 and 90 years in Sweden, Norway, Iceland, Denmark and Finland, in the period 1990-2014. Methods: Demographic information was collected from national statistical databases and the Human Mortality Database. Results: All metrics on population ageing increased during the study period, but there were some cross-country variations. Finland experienced a notably steep increase in the proportion of 75+ and 90+ year olds compared to the other countries. Regarding the proportion reaching old ages, the Finnish lagged behind from the beginning, but females decreased this difference. The Danes were more similar to the other countries at the beginning, but did not experience the same increase over time. Gender-specific LE at age 75 and 90 years was similar overall in the five countries. Conclusions: Developments in cross-country variation suggest that survival until old age has become more similar for Finnish females and more different for Danish males and females compared with the other countries in recent decades. This provides perspectives on the potential to improve longevity in Denmark and Finland. Similarities in LE in old age suggest that expected mortality in old age has been more similar throughout the study period.

Predictors of long-term care among nonagenarians: the Vitality 90 + Study with linked data of the care registers.

BACKGROUND: The need for long-term care services increases with age. However, little is known about the predictors of long-term care (LTC) entry among the oldest old. AIMS: Aim of this study was to assess predictors of LTC entry in a sample of men and women aged 90 years and older. METHODS: This study was based on the Vitality 90 + Study, a population-based study of nonagenarians in the city of Tampere, Finland. Baseline information about health, functioning and living conditions were collected by mailed questionnaires. Information about LTC was drawn from care registers during the follow-up period extending up to 11 years. Cox regression models were used for the analyses, taking into account the competing risk of mortality. RESULTS: During the mean follow-up period of 2.3 years, 844 (43%) subjects entered first time into LTC. Female gender (HR 1.39, 95% CI 1.14-1.69), having at least two chronic conditions (HR 1.24, 95% CI 1.07-1.44), living alone (HR 1.37, 95% CI 1.15-1.63) and help received sometimes (HR 1.23, 95% CI 1.02-1.49) or daily (HR 1.68, 95% CI 1.38-2.04) were independent predictors of LTC entry. CONCLUSION: Risk of entering into LTC was increased among women, subjects with at least two chronic conditions, those living alone and with higher level of received help. Since number of nonagenarians will increase and the need of care thereby, it is essential to understand predictors of LTC entry to offer appropriate care for the oldest old in future.

Long-term care is increasingly concentrated in the last years of life: a change from 2000 to 2011.

Background: The use of long-term care (LTC) is common in very old age and in the last years of life. It is not known how the use pattern is changing as death is being postponed to increasingly old age. The aim is to analyze the association between the use of LTC and approaching death among old people and the change in this association from 2000 to 2011. Methods: The data were derived from national registers. The study population consists of 315 458 case-control pairs. Cases (decedents) were those who died between 2000 and 2011 at the age of 70 years or over in Finland. The matched controls (survivors) lived at least 2 years longer. Use of LTC was studied for the last 730 days for decedents and for the same calendar days for survivors. Conditional logistic regression analyses were performed to test the association of LTC use with decedent status and year. Results: The difference in LTC use between decedents and survivors was smallest among the oldest (OR 9.91 among youngest, 4.96 among oldest). The difference widened from 2000 to 2011 (OR of interaction of LTC use and year increased): use increased or held steady among decedents, but decreased among survivors. Conclusions: The use of LTC became increasingly concentrated in the last years of life during the study period. The use of LTC is also common among the oldest survivors. As more people live to very old age, the demand for LTC will increase.

Trends in the use and costs of round-the-clock long-term care in the last two years of life among old people between 2002 and 2013 in Finland.

BACKGROUND: The structure of long-term care (LTC) for old people has changed: care has been shifted from institutions to the community, and death is being postponed to increasingly old age. The aim of the study was to analyze how the use and costs of LTC in the last two years of life among old people changed between 2002 and 2013. METHODS: Data were derived from national registers. The study population contains all those who died at the age of 70 years or older in 2002-2013 in Finland (N = 427,078). The costs were calculated using national unit cost information. Binary logistic regression and Cox proportional hazard models were used to study the association of year of death with use and costs of LTC. RESULTS: The proportion of those who used LTC and the sum of days in LTC in the last two years of life increased between 2002 and 2013. The mean number of days in institutional LTC decreased, while that for sheltered housing increased. The costs of LTC per user decreased. CONCLUSIONS: Use of LTC in the last two years of life increased, which was explained by the postponement of death to increasingly old age. Costs of LTC decreased as sheltered housing replaced institutional LTC. However, an accurate comparison of costs of different types of LTC is difficult, and the societal costs of sheltered housing are not well known.

Endometrial cancer risk factors among Lynch syndrome women: a retrospective cohort study.

BACKGROUND: Lynch syndrome (LS) is associated with a significant lifetime risk of endometrial cancer (EC). There are limited data on factors modifying the EC risk in LS patients. METHODS: The study cohort included 136 LS mutation-positive women. Exposure data were collected by postal questionnaires. Cox regression model was used to estimate the associations between lifestyle, hormonal, reproductive and medical factors and the risk of EC. RESULTS: Increased EC risk was associated with type II diabetes and hypercholesterolaemia in univariable (HR 3.21, (95% CI 1.34-7.78), P=0.009 and HR 2.08, (95% CI 1.11-3.90), P=0.02; respectively) and with diabetes and duration of hormone replacement therapy (HRT) in multivariable analysis (HR 4.18 (95% CI 1.52-11.52), P=0.006 and HR 1.07 (95% CI 1.02-1.13), P=0.010; respectively). CONCLUSIONS: Prevention of diabetes and avoiding long-duration HRT are potential targets for reduction of EC risk in women with LS.

Defects in mitochondrial fatty acid synthesis result in failure of multiple aspects of mitochondrial biogenesis in Saccharomyces cerevisiae.

Mitochondrial fatty acid synthesis (mtFAS) shares acetyl-CoA with the Krebs cycle as a common substrate and is required for the production of octanoic acid (C8) precursors of lipoic acid (LA) in mitochondria. MtFAS is a conserved pathway essential for respiration. In a genetic screen in Saccharomyces cerevisiae designed to further elucidate the physiological role of mtFAS, we isolated mutants with defects in mitochondrial post-translational gene expression processes, indicating a novel link to mitochondrial gene expression and respiratory chain biogenesis. In our ensuing analysis, we show that mtFAS, but not lipoylation per se, is required for respiratory competence. We demonstrate that mtFAS is required for mRNA splicing, mitochondrial translation and respiratory complex assembly, and provide evidence that not LA per se, but fatty acids longer than C8 play a role in these processes. We also show that mtFAS- and LA-deficient strains suffer from a mild haem deficiency that may contribute to the respiratory complex assembly defect. Based on our data and previously published information, we propose a model implicating mtFAS as a sensor for mitochondrial acetyl-CoA availability and a co-ordinator of nuclear and mitochondrial gene expression by adapting the mitochondrial compartment to changes in the metabolic status of the cell.

Place of living at end-of-life according to cause of death: a comparative analysis of all decedents 70 years or older in 2009-2013 in Finland and Norway.

BACKGROUND: Time at home at end-of-life is perceived as valuable to individuals. Increasing home care is therefore often a political goal. Yet, little is known about where individuals live towards their end-of-life. Our aim was to describe where individuals reside their last 6 months of life in Finland and Norway, and how this differed by cause of death, sex, age, marital status, and income. METHODS: We used individual-leveled national registry data on all decedents aged >70 years in 2009-2013 to describe the number of days individuals spent at home, in hospital, in long-term care (LTC) and short-term care (STC) facilities. We described the place of residence for all and by causes of death: cancer, diseases of the circulatory system, disease in the respiratory system, and mental and behavioral disorders (primarily dementia). We analyzed how age, marital status (indicating informal care), and income associated with place of residence. Analyses were stratified by sex and country. RESULTS: During the last 6 months of life, decedents in Finland (n=186,017) and Norway (n=159,756) spent similar amounts of days in hospital (8 and 11 days) and in STC facilities (15 and 13 days). Finnish decedents spent more days at home (96 vs. 84 days) and fewer days in LTC facilities (64 vs. 80 days). Living arrangement differed similarly by cause of death in the two countries, e.g., decedents from cancer and mental and behavioral disorders spent 123 [113] vs. 29 [21] days at home in Finland (Norway). In both countries, for all causes of death, lower age and marital status were associated with more days at home, for both males and females. While those with higher income spent more days at home in Norway, the opposite was found in Finland. CONCLUSIONS: Older individual's living arrangements in the last 6 months of life were similar in Finland and Norway but differed by cause of death. Younger individuals and those with access to informal care spent more days at home, compared to their counterparts. With aging populations, more individuals will likely need LTC at their end of life. Policies should align with these needs when developing future health care services.

ESYT1 tethers the ER to mitochondria and is required for mitochondrial lipid and calcium homeostasis.

Mitochondria interact with the ER at structurally and functionally specialized membrane contact sites known as mitochondria-ER contact sites (MERCs). Combining proximity labelling (BioID), co-immunoprecipitation, confocal microscopy and subcellular fractionation, we found that the ER resident SMP-domain protein ESYT1 was enriched at MERCs, where it forms a complex with the outer mitochondrial membrane protein SYNJ2BP. BioID analyses using ER-targeted, outer mitochondrial membrane-targeted, and MERC-targeted baits, confirmed the presence of this complex at MERCs and the specificity of the interaction. Deletion of ESYT1 or SYNJ2BP reduced the number and length of MERCs. Loss of the ESYT1-SYNJ2BP complex impaired ER to mitochondria calcium flux and provoked a significant alteration of the mitochondrial lipidome, most prominently a reduction of cardiolipins and phosphatidylethanolamines. Both phenotypes were rescued by reexpression of WT ESYT1 and an artificial mitochondria-ER tether. Together, these results reveal a novel function for ESYT1 in mitochondrial and cellular homeostasis through its role in the regulation of MERCs.

Effects of municipality factors on care transitions.

AIMS: To analyse whether transitions between care settings differ between municipalities in the last 2 years of life among older people in Finland. METHODS: Data were derived from Finnish national registers, and include all those who died in 2002 and 2003 at the age of 70 or older except those living in very small municipalities (n=67,027). Data include admissions and discharges from health and social care facilities (university hospitals, general hospitals, health centres, residential care facilities) and time spent outside care facilities for 730 days prior to death. Three-level negative binomial regression analyses were performed to study the effect of municipal factors on (1) the total number of all care transitions, (2) the number of transitions between home and different care facilities, and (3) transitions between different care facilities. RESULTS: The municipality of residence had only a minor effect on the total number of care transitions, but greater variation between municipalities was found when different types of care transition were examined separately. Largest differences were found in care transitions involving specialised care. Age structure, urbanity, and economic situation of the municipality had an impact on several different care transitions. CONCLUSION: The total number of care transitions in 2 final years of life was approximately similar irrespective of the municipality of residence, but the findings imply differences in transitioning specialised care. Potentially, this may suggest inequality between the municipalities, but more detailed studies are needed to confirm the factors underlying these differences.

Identification of Proximity Interactors of Mammalian Nucleoid Proteins by BioID.

Mitochondrial nucleoids are compact nucleoprotein complexes, in which mtDNA is located, replicated, and transcribed. Several proteomic approaches have been previously employed to identify nucleoid proteins; however, a consensus list of nucleoid-associated proteins has not been generated. Here we describe a proximity-biotinylation assay, BioID, which allows identification of proximity interactors of mitochondrial nucleoid proteins. It uses a promiscuous biotin ligase fused to a protein of interest which covalently attaches biotin to lysine residues of its proximal neighbors. Biotinylated proteins can be further enriched by a biotin-affinity purification and identified by mass-spectrometry. BioID can identify transient and weak interactions and can be used to identify changes in the interactions upon different cellular treatments, for different protein isoforms or for pathogenic variants.

Perceived benefits of digital health and social services among older adults: A population-based cross-sectional survey.

Objective: The aim of this study was to describe the benefits of digital health and social services perceived by older adults and to examine factors associated with perceiving these benefits. Several factors related to (a) sociodemographic characteristics, (b) area of residence, (c) physical, cognitive, psychological, and social functioning, and (d) Internet use, were examined. Methods: The present sample included 8019 respondents aged between 75 and 99 years. The inverse probability weighting method was used to correct for bias. Linear regression analyses were used to examine the associations. Results: The ease of use of the services regardless of the time and location was perceived as the most beneficial. Convenient distance to local health or social services (parameter estimate = 0.15 [0.08-0.23]), good functional ability (PE = 0.08 [0.01-0.14]), good vision (PE = 0.15 [0.04-0.25]), ability to learn (PE = 0.05 [0.01-0.10]) and living with someone (PE = 0.08 [95% CI 0.04-0.13]) were associated with perceiving more benefits. In addition, access to the Internet (PE = 0.12 [0.06-0.19]) and independent use of the Internet (PE = 0.23 [0.17-0.29]) were associated with perceiving more benefits. Conclusions: Older adults who are healthier, have a social relationship in their everyday life or have easier access to traditional services seem to perceive more benefits from digital health and social services. Digital services should be developed to correspond with special needs caused by disadvantages in health and the social environment. To facilitate the use of digital health and social services, more efforts should be made to enhance older adults' perceptions of their benefits.

Loss of mitochondrial Chchd10 or Chchd2 in zebrafish leads to an ALS-like phenotype and Complex I deficiency independent of the mitochondrial integrated stress response.

Mutations in CHCHD10 and CHCHD2, encoding two paralogous mitochondrial proteins, have been identified in cases of amyotrophic lateral sclerosis, frontotemporal lobar degeneration, and Parkinson's disease. Their role in disease is unclear, though both have been linked to mitochondrial respiration and mitochondrial stress responses. Here, we investigated the biological roles of these proteins during vertebrate development using knockout (KO) models in zebrafish. We demonstrate that loss of either or both proteins leads to motor impairment, reduced survival and compromised neuromuscular junction integrity in larval zebrafish. Compensation by Chchd10 was observed in the chchd2-/- model, but not by Chchd2 in the chchd10-/- model. The assembly of mitochondrial respiratory chain Complex I was impaired in chchd10-/- and chchd2-/- zebrafish larvae, but unexpectedly not in a double chchd10-/- and chchd2-/- model, suggesting that reduced mitochondrial Complex I cannot be solely responsible for the observed phenotypes, which are generally more severe in the double KO. We observed transcriptional activation markers of the mitochondrial integrated stress response (mt-ISR) in the double chchd10-/- and chchd2-/- KO model, suggesting that this pathway is involved in the restoration of Complex I assembly in our double KO model. The data presented here demonstrates that the Complex I assembly defect in our single KO models arises independently of the mt-ISR. Furthermore, this study provides evidence that both proteins are required for normal vertebrate development.

The impact of dementia on care transitions during the last two years of life.

BACKGROUND: Dementia is one of the main challenges to our health and social care. This study compares the number and timing of transitions between care settings in the last 2 years of life among older people with and without dementia. METHODS: Data were derived from Finnish national registers, and include all those who died in 2002 and 2003 at the age of 70 or older (n = 70,366). Negative binomial regression analyses were used to analyse the impact of dementia on number of transitions among people with and without dementia and to adjust the number for age, gender and other diagnoses. RESULTS: In the group that lived at home 2 years before death people with a dementia diagnosis had 32% more care transitions than people without dementia, while the group that was in residential care facility 2 years before death people with dementia had 12% fewer moves than those without dementia The average number of transition was highest in last 3 months of life. People with dementia had their last move more often between care facilities and hospitals offering basic health care than people without dementia. CONCLUSION: Dementia has a significant impact on the number and type of transitions. As the number of people with dementia increases, the quality and equity of care of these patients in their last years constitute a special challenge.

Through Thick and Thin: The Meaning of Dementia for the Intimacy of Ageing Couples.

As the population ages, the number of people with dementia increases. An emerging body of research is focusing on living with dementia and understanding the experience of caring and the care burden. There is much less research on the meaning of dementia from the perspective of an older couple's spousal relationship and related intimacy. This qualitative study explores the meanings of emotional and physical intimacy and the changes brought by dementia in the couplehood of persons with dementia and their spousal carers. The data comprise semi-structured interviews with 35 persons. The interviews were analysed using inductive qualitative content analysis. Four themes describing the meanings of relational intimacy were identified: intimacy as a striving force, intimacy turning into worrisome behaviour, intimacy as physical and emotional dependency, and intimacy turning into one-sided caring for a partner. Dementia changes the intimate relationship in many ways, but shared affection and long-term partnership help maintain the spousal relationship. While dementia may bring about conflicts and behavioural challenges in an intimate relationship, the couple's shared intimacy and a sense of responsibility for one another may serve as a resource and support the continuity of couplehood.
