- Background: With a growing elderly population worldwide, the prevalence of dementia is rapidly increasing. Studies from high income countries have shown that belonging to a minority ethnic group increases the risk of health disadvantages. Objective: The aim of the present registry-based study was to identify potential differences in diagnostics, treatment, and care of individuals with dementia focusing on foreign-born in Sweden and the impact of country level socioeconomic position (SEP). Methods: The study was based on a large dataset from the Swedish Dementia Registry (SveDem) and the Swedish Tax Agency's population registry. Data on demographic variables, cognitive tests, clinical assessments, medication, diagnosis, and interventions initiated at diagnosis were collected. Country level SEP was determined by country of birth as classified by World Bank Country and Lending groups. Results: Of 57,982 patients with dementia registered in SveDem, 7,171 (12.4%) were foreign-born. The foreign-born were significantly younger at diagnosis (p < 0.001), had a lower MMSE score (p < 0.001), lower odds of receiving a specific dementia diagnosis (p < 0.001), lower use of acetylcholinesterase inhibitors (p < 0.001), and overall a higher use of neuroleptics compared with the Swedish-born group. The lower SEP, the greater differences to Swedish-born were seen in many of the examined variables. Conclusion: There were significant differences in dementia diagnostics, treatment, and care between foreign-born and Swedish-born, a lower SEP indicating greater differences. Further research should focus on various socioeconomic aspects and health care outcomes for a more profound analysis of equity in dementia care.

Tidskriftsartikel (refereegranskat)abstract
- The clinical diagnosis of vascular dementia (VaD) is based on imaging criteria, and specific biochemical markers are not available. Here, we investigated the potential of cerebrospinal fluid (CSF) lipocalin 2 (LCN2), a secreted glycoprotein that has been suggested as mediating neuronal damage in vascular brain injuries. The study included four independent cohorts with a total n=472 samples. LCN2 was significantly elevated in VaD compared to controls, Alzheimers disease (AD), other neurodegenerative dementias, and cognitively unimpaired patients with cerebrovascular disease. LCN2 discriminated VaD from AD without coexisting VaD with high accuracy. The main findings were consistent over all cohorts. Neuropathology disclosed a high percentage of macrophages linked to subacute infarcts, reactive astrocytes, and damaged blood vessels in multi-infarct dementia when compared to AD. We conclude that CSF LCN2 is a promising candidate biochemical marker in the differential diagnosis of VaD and neurodegenerative dementias. Diagnosis of vascular dementia is hampered by the lack of biochemical markers for this disease. Here, the authors show that vascular dementia is associated with increased lipocalin-2 in cerebrospinal fluid, compared to controls and patients with other forms of dementia.

Tidskriftsartikel (refereegranskat)abstract
- Background: The relationship between cerebrospinal fluid (CSF) biomarkers and the clinical features of idiopathic normal pressure hydrocephalus (iNPH) has been inconclusive. We aimed to evaluate CSF biomarkers reflecting Alzheimer’s disease (AD)-related amyloid β (Aβ) aggregation, tau pathology, neuroinflammation and axonal degeneration in relation to the clinical features of pre- and post-shunt surgery in iNPH patients. Methods: Mini Mental State Examination (MMSE) scores and gait velocity were evaluated pre- and postoperatively in cohorts of 65 Finnish (FIN) and 82 Swedish (SWE) iNPH patients. Lumbar CSF samples were obtained prior to shunt surgery and analysed for soluble amyloid precursor protein alpha (sAPPα) and beta (sAPPβ); amyloid-β isoforms of 42, 40 and 38 (Aβ42, Aβ40, Aβ38); total tau (T-tau); phosphorylated tau (P-tau181); neurofilament light (NfL) and monocyte chemoattractant protein 1 (MCP1). Results: Preoperative patient characteristics showed no significant differences between patients in the FIN and SWE cohorts. Patients in both cohorts had significantly improved gait velocity after shunt surgery (p < 0.0001). Low CSF T-tau and absence of apolipoprotein E ε4 predicted over 20% gait improvement postoperatively (p = 0.043 and p = 0.008). Preoperative CSF T-tau, P-tau181 and NfL correlated negatively with MMSE scores both pre- (p < 0.01) and post-surgery (p < 0.01). Furthermore, T-tau, NfL and Aβ42 correlated with MMSE outcomes (p < 0.05). Low preoperative CSF P-tau181 (p = 0.001) and T-tau with NfL (p < 0.001 and p = 0.049) best predicted pre- and postoperative MMSE scores greater than or equal to 26. Conclusions: CSF biomarkers of neurodegeneration appeared to correlate with pre- and postoperative cognition, providing a window into neuropathological processes. In addition, preoperative CSF neurodegeneration biomarkers may have potential in the prediction of gait and cognitive outcomes after shunt surgery. © 2022, The Author(s).

- The present study explored the nature of the semantic deterioration normally displayed in the course of Alzheimer’s disease (AD). The aim was to disentangle the extent to which semantic memory problems in patients with AD are best characterized as loss of semantic knowledge rather than difficulties in accessing semantic knowledge.A longitudinal approach was applied. The same semantic tests as well as same items were used across three test occasions a year apart. Twelve Alzheimer patients and 20 matched control subjects, out of a total of 25 cases in each group, remained at the final test occasion.Alzheimer patients were impaired in all the semantic tasks as compared to the matched comparison group. A progressing deterioration was evident during the study period. Our findings suggest that semantic impairment is mainly due to loss of information rather than problems in accessing semantic information.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: Care managers and professional caregivers of home care services are sometimes unaware of the psychosocial approaches to the challenging behaviour of dementia. Therefore, we developed a Behaviour Analytics & Support Enhancement (BASE) programme. We investigated the effects of the programme on the attitudes towards dementia care among professionals. Method: Forty-six participants in Japan received training in August 2016. The ongoing monitoring and assessment system was introduced to the participants for repeated measures of challenging behaviour. A 1-day follow-up meeting for debriefing was also performed after two months. A baseline and follow-up questionnaire survey was administered to the participating caregivers using a Japanese version of the Approaches to Dementia Questionnaire (ADQ) and the Zarit Burden Interview (ZBI). Results: A significant improvement was observed in the total ADQ score among the participating caregivers from baseline to follow-up assessment. There was no significant difference between the baseline and follow-up assessment in the ZBI scores. In the follow-up meeting, several participants reported challenges and suggested solutions in facilitating a discussion on an action plan among professionals from various organizations. Conclusion: The implementation of the programme resulted in enhanced attitudes towards dementia care among the participants without an increased burden of care. Future studies should examine the programme's effectiveness on the challenging behaviour of persons with dementia.

Tidskriftsartikel (refereegranskat)abstract
- Background: Concern has been raised that the COVID-19 pandemic and consequent social distancing measures may increase neuropsychiatric symptoms in people with dementia. Thus, we developed and delivered an e-learning training course to professional caregivers on using a web-based tool for psychosocial interventions for people with dementia. Objective: The aim of our study was to evaluate the feasibility and efficacy of an e-learning course in combination with a web-based tool in addressing neuropsychiatric symptoms of dementia. Methods: A quasi-experimental design was used in Tokyo, Japan. The e-learning course was delivered three times to professional caregivers between July and December 2020. Caregivers who completed the course assessed the level of neuropsychiatric symptoms in people with dementia using the total score from the Neuropsychiatric Inventory (NPI) via a web-based tool. The primary outcome measures were the number of caregivers who implemented follow-up NPI evaluations by March 2021 and the change in NPI scores from baseline to their most recent follow-up evaluations. As a control group, information was also obtained from professional caregivers who completed a face-to-face training course using the same web-based tool between July 2019 and March 2020. Results: A total of 268 caregivers completed the e-learning course in 2020. Of the 268 caregivers, 56 (20.9%) underwent follow-up evaluations with 63 persons with dementia. The average NPI score was significantly reduced from baseline (mean 20.4, SD 16.2) to the most recent follow-up evaluations (mean 14.3, SD 13.4). The effect size was assumed to be medium (Cohen drm [repeated measures]=0.40). The control group consisted of 252 caregivers who completed a face-to-face training course. Of the 252 caregivers, 114 (45.2%) underwent follow-up evaluations. Compared to the control group, caregivers who completed the e-learning course were significantly less likely to implement follow-up evaluations (χ2 1=52.0, P<.001). The change in NPI scores did not differ according to the type of training course (baseline-adjusted difference=-0.61, P=.69). Conclusions: The replacement of face-to-face training with e-learning may have provided professionals with an opportunity to participate in the dementia behavior analysis and support enhancement (DEMBASE) program who may not have participated in the program otherwise. Although the program showed equal efficacy in terms of the two training courses, the feasibility was suboptimal with lower implementation levels for those receiving e-learning training. Thus, further strategies should be developed to improve feasibility by providing motivational triggers for implementation and technical support for care professionals. Using online communities in the program should also be investigated.

Tidskriftsartikel (refereegranskat)abstract
- Background: A psychosocial dementia care programme for challenging behaviour (DEMBASE®) was developed in collaboration with a Swedish BPSD-registry team for in-home care services use in Japan. The programme consisted of a web-based tool for the continued assessment of challenging behaviours and interdisciplinary discussion meetings. Effectiveness of the adapted programme was verified through a cluster-randomised controlled trial. The Tokyo Metropolitan Government provided municipal funding to introduce the programme into daily practice beginning in April 2018. Objectives: To investigate both facilitators and barriers associated with programme implementation. Design: A secondary analysis of qualitative and quantitative data. Settings: Data were collected in naturalistic long-term care settings from April 2018 to March 2019. Participants: A total of 138 professionals and 157 people with dementia participated in the programme. Methods: Challenging behaviour in persons with dementia was assessed by professionals using a total Neuropsychiatric Inventory score. Data on expected facilitators and barriers were extracted for qualitative analysis from a debriefing meeting between professionals. Results: Of the 157 persons with dementia, 81 (51.6%) received follow-up behavioural evaluations by March 2019. The average level of challenging behaviour was significantly reduced for 81 persons from baseline to their most recent follow-up evaluations. Facilitators included ‘programme available for care managers’, ‘visualised feedback on professionals’ work’, ‘affordable for providers and professionals’ and ‘media coverage’. Barriers included ‘professionals from different organisations’, ‘unpaid work’, ‘operation requirement for municipalities’ and ‘conflict with daily benefit-oriented framework’. Conclusions: A follow-up evaluation was not fully achieved. Further strategies to address barriers may include the development of a benefit-rewarding scheme for interdisciplinary discussion meetings, an e-learning system capable of substituting training course portions and a cross-municipality training course.

- Little is known about the effectiveness of a psychosocial behaviour management programme on home-dwelling people with dementia. We developed a Behaviour Analytics & Support Enhancement (BASE) programme for care managers and professional caregivers of home care services in Japan. We investigated the effects of BASE on challenging behaviour of home-dwelling people with dementia. Methods: A cluster-randomized controlled trial was conducted with home care providers from 3 different districts in Tokyo. Each provider recruited persons with dementia aged 65 years or older to receive home care in the BASE programme in August 2016. An online monitoring and assessment system was introduced to the intervention group for repeated measures of challenging behaviour with a total score of the Neuropsychiatric Inventory. Care professionals in both the intervention and control groups evaluated challenging behaviour of persons with dementia at baseline (September 2016) and follow-up (February 2017). Results: A majority of persons with dementia had Alzheimer disease (59.3%). One-hundred and forty-one persons with dementia were included in the intervention group and 142 in the control group. Multilevel modelling revealed a significant reduction in challenging behaviour in the intervention group after 6 months (mean score, 18.3 to 11.2) compared with that of the control group (11.6 to 10.8; P <.05). Conclusion: The implementation of the BASE programme resulted in a reduction of challenging behaviour of home-dwelling people with dementia. Future research should examine the long-term effects of behaviour management programmes on behaviour, nursing home placement, and hospital admission of home-dwelling people with dementia.
