Maar liefst 60 tot 80 procent van alle mensen met dementie heeft de ziekte van Alzheimer. Steeds meer onderzoek laat zien dat er veranderingen in de taal en motoriek zijn waar te nemen in alle stadia van de ziekte van Alzheimer. Wij willen onderzoeken of een combinatie van talige en motorische vaardigheden zou kunnen bijdragen aan de vroegdiagnostiek van de ziekte van Alzheimer.

In het herstellen en behouden van zinvolle bezigheden voor mensen met een lichte of matige vorm van van de ziekte van Alzheimer is doelstelling van groot praktisch belang. De studies gericht op dit doel hebben vertrouwd op de verschillende strategieën van zelfmanagement van instruction cues. Zeven studies werden gevonden die plaats hadden in de periode 2008-2012 (dat wil zeggen, de periode waarin onderzoek op dit gebied daadwerkelijk vorm heeft gekregen). Die strategieën bestaan uit het gebruik van (1) verbale signalen aangeboden via audiorecorders, (2) visuele signalen aangeboden via computersystemen, en (3) een combinatie van verbale en visuele signalen gepresenteerd via computersystemen. Dit artikel geeft een overzicht van de hiervoor genoemde strategieën en bespreekt de resultaten daarvan, hun algemene doeltreffendheid, op prestaties en stemmingen, en hun geschiktheid en bruikbaarheid. Thema's voor toekomstig onderzoek werden eveneens onderzocht. ABSTRACT Helping people with mild or moderate Alzheimer's disease restore and maintain constructive occupations is an objective of great practical importance. Studies targeting this goal have relied on different strategies for self-management of instruction cues. Seven studies were identified in the period 2008- 2012 (i.e. the period in which research in this area has actually taken shape). These strategies consist of the use of (1) verbal cues presented via audio recording devices, (2) pictorial cues presented via computer-aided systems and (3) combinations of verbal and pictorial cues presented via computer-aided systems. This paper reviews these strategies and discusses their outcomes, their overall effectiveness on performance and mood, and their suitability and practicality. Issues for future research are also examined.

Paratonia, a distinctive form of hypertonia in patients with dementia, causes loss of functional mobility in early stage dementia to severe contractures and pain in the late stages. The pathogenesis of paratonia is not well understood. Patients in early stage dementia with diabetes mellitus showed a significantly higher risk for the development of paratonia. Both Alzheimer disease and diabetes mellitus are related to higher concentrations of advanced glycation end-products (AGEs). The purpose of this study is to explore the association of AGEs with the prevalence and severity of paratonia in patients with Alzheimer disease.DESIGN: Observational longitudinal, 1-year follow-up cohort study with 3 assessments.SETTING: Day care centers for patients with dementia.PARTICIPANTS: A total of 144 community-dwelling patients with early stage Alzheimer or Alzheimer/vascular disease were recruited from 24 dementia day care centers in The Netherlands.MEASUREMENTS: The presence of paratonia (Paratonia Assessment Instrument), the severity of paratonia (Modified Ashworth Scale for paratonia), and AGE levels (AGE-reader).RESULTS: From the 144 participants (56.3% female and 43.7% male, with a mean [standard deviation] age of 80.7 [7.7] years), 118 participants were available for final follow-up. A significant association between AGE levels and the presence of paratonia (odds ratio 3.47, 95% confidence interval [CI] 1.87-6.44, P < .001) and paratonia severity (β = 0.17, 95% CI 0.11-0.23, P < .001) was determined. In participants who developed paratonia and those with persistent paratonia throughout the study the AGE levels (95% CI -0.38 to -0.13, P < .001 and 95% CI -0.46 to -0.06, P = .012, respectively) and the severity of paratonia (95% CI -0.60 to -0.35, P < .001 and 95% CI -0.38 to -0.12, P < .001, respectively) significantly increased, whereas the AGE levels remained stable in those participants without paratonia. Notwithstanding, change in AGE levels was not significantly (P = .062) related to change in paratonia severity, mixed model analyses provided evidence for both a significant time and between participant effect of AGEs on paratonia severity.CONCLUSIONS: This study suggests that elevated AGE levels are a contributing factor to paratonia and its severity and could be the result of peripheral biomechanical changes reducing elasticity and increasing stiffness. These results provide a new perspective on paratonia and gives rise to further research whether paratonia could be postponed or movement stiffness can be improved by reducing AGE levels.

Pianist Misha Mengelberg (79) wordt beschouwd als de meest invloedrijke jazzmusicus binnen de Nederlandse jazzmuziek. Maar Mengelberg heeft dementie en kampt de laatste jaren met toenemende geheugen- en taalproblemen. Al zal de rol van muziek in zijn leven nooit veranderen, ook niet nu hij de ziekte van Alzheimer heeft. Psycholoog Frans Hoogeveen beaamt dit: “Muziek brengt herinneringen en emoties tot leven. Daar kunnen mensen met dementie ook nog steeds van genieten.”

This paper presents a study of sensor data from a person who developed Alzheimer’s disease during a 4-year monitoring period and who is monitored with simple ambient sensors in her home. Our aim is to find data analysis methods that reveal relevant changes in the sensor pattern that occur before the diagnosis. We focus on the quantification of regularity, which is identified as a relevant indicator for the assessment of a disease such as Alzheimer’s. Two unsupervised methods are studied. Restricted Boltzmann Machines are trained and the resulting weights are visualized to see whether there arechanges in regularity in the behavioral pattern. Fast Fourier Transformation is applied to the sensor data and the spectral characteristics are determined and compared with the same purpose. Both methods reveal changes in the pattern between different periods. Both methods therefore are useful in quantifying and understanding changes in the regularity of the daily pattern.

Ageing-in-place is the preferred way of living for older individuals in an ageing society. It can be facilitated through architectural and technological solutions in the home environment. Dementia poses additional challenges when designing, constructing, or retrofitting housing facilities that support ageing-in-place. Older adults with dementia and their partners ask for living environments that support independence, compensate for declining and vitality, and lower the burden of family care. This study reports the design process of a demonstration home for people with dementia through performing a literature review and focus group sessions. This design incorporates modifications in terms of architecture, interior design, the indoor environment, and technological solutions. Current design guidelines are frequently based on small-scale studies, and, therefore, more systematic field research should be performed to provide further evidence for the efficacy of solutions. The dwellings of people with dementia are used to investigate the many aspects of supportive living environments for older adults with dementia and as educational and training settings for professionals from the fields of nursing, construction, and building services engineering.

Background: This paper presents the researchers’ experiences with recruiting people living with dementia for a field study aimed to test or develop non-pharmacological interventions. Performing this kind of research is necessary to be able to provide appropriate and effective interventions for people with dementia. Research aim/questions: The aim is to find out the pros and cons of recruiting PwD for field studies comprising technological innovations. Methods: This short paper is based on the experiences of researchers during their studies, combined with a rapid literature search. Results: Incorporating technological innovations as a non-pharmacological intervention poses a challenge to recruitment success. Several influencing factors influence the success of the recruitment process. For example, personal contact or recruitment via welfare and care organizations can be helpful. Conclusion: Collaboration and different strategies can be helpful for the recruitment process.

Light therapy for older persons with dementia is often administered with light boxes, even though indoor ambient light may more comfortably support the diverse lighting needs of this population. Our objective is to investigate the influence of indoor daylight and lighting on the health of older adults with dementia living in long-term care facilities. A systematic literature search was performed within PubMed, CINAHL, PsycINFO, Web of Science and Scopus databases. The included articles (n=37) were published from 1991 to 2020. These articles researched the influence of existing and changed indoor light conditions on health and resulted in seven categories of health outcomes. Although no conclusive evidence was found to support the ability of indoor light to decrease challenging behaviors or improve circadian rhythms, findings of two studies indicate that exposure to (very) cool light of moderate intensity diminished agitation. Promising effects of indoor light were to reduce depressive symptoms and facilitate spatial orientation. Furthermore, there were indications that indoor light improved one’s quality of life. Despite interventions with dynamic lighting having yielded little evidence of its efficacy, its potential has been insufficiently researched among this study population. This review provides a clear and comprehensive description of the impact of diverse indoor light conditions on the health of older adults with dementia living in long-term care facilities. Variation was seen in terms of research methods, (the description of) light conditions, and participants’ characteristics (types and severity of dementia), thus confounding the reliability of the findings. The authors recommend further research to corroborate the beneficial effects of indoor light on depression and to clarify its role in supporting everyday activities of this population. An implication for practice in long-term care facilities is raising the awareness of the increased lighting needs of aged residents. Original article at: https://doi.org/10.2147/CIA.S297865
