“…Whilst there has been research on the combination of digital and multisensory environments (see Moyle et al, 2018 Virtual Reality Forest, for example), there has been little work conducted on creating immersive, multisensory environments tailored to the life story of the individual with dementia. To date, Snoezelen has been the most widely used approach to using immersive, sensory stimulation with people living with dementia (Pinto et al, 2020). Deriving from the Dutch terms snuffelen (to seek and explore) and doezelen (to relax), Snoezelen multisensory environments offer a choice of olfactory, auditory, visual and/or tactile stimuli to individuals so that they may explore the stimuli whilst being in a state of relaxation (Baker et al, 2001).…”

Meaningful activities in dementia care can promote the co-construction of narrative identity in caregiving relationships, helping to preserve the sense of self in people with dementia. Purpose: Informed by symbolic interactionism and Deweyan transactionalism, the aim of this study was to develop a transactional model of how narrative identity and relationships are promoted through the use of a new technological solution, SENSE-GARDEN, that uses digital technologies and multisensory stimuli to facilitate individualized, meaningful activities. Method: We conducted a qualitative interview study to explore the experiences of people with moderate to advanced dementia and their caregivers in Norway and Portugal. After using SENSE-GARDEN for 12-16 weeks, 20 participants (7 persons with dementia and 13 caregivers) were interviewed. The interviews were analysed using reflexive thematic analysis. Results: Three themes were generated: openness, learning, and connection. Findings suggest that SENSE-GARDEN can stimulate emotional experiences, preserve narrative identity, and foster interpersonal relationships. These findings are illustrated through a transactional model. Conclusion:This study highlights the complex multitude of factors affecting personenvironment interactions in which narrative identity and relationships are constructed. To better understand these factors, future work should adopt a holistic approach to studying new methods of creating meaningful activities in dementia care.

“…However, to the best of our knowledge, no study has used an olfactory test to examine the effects of interventions on the perception of olfactory function. Some studies have demonstrated that odor exposure can effectively evoke autobiographical memories and trigger strong feelings about a previous event, especially for individuals with mild Alzheimer's disease or related dementia (El Haj et al, 2017;Glachet et al, 2019;Pinto et al, 2020). Although these researchers have suggested that olfactory stimulation 10.3389/fpsyg.2022.1003325 can assist with memory retrieval, its effects on cognition improvement and the delay of dementia progression have not been verified.…”

“…Compared with pharmacotherapy, non-pharmacological interventions have been recognized as having fewer adverse effects and being a cost-effective approach for improving patients’ quality of life ( Pinto et al, 2020 ). Several well-known treatments and therapies have been proposed, such as cognitive-emotional interventions, sensory stimulation interventions, behavior management techniques, and physical exercise ( Dimitriou and Tsolaki, 2017 ).…”

“…Sensory stimulation interventions mainly target patients with moderate-to-severe dementia, because reduced intellectual reasoning, limited verbal skills, and restless or agitated behavior may result in difficulty attending traditional therapy or leisure activities ( Spaull et al, 1998 ). However, these interventions may also slow down deterioration and increase daily autonomy in patients with less severe dementia ( Pinto et al, 2020 ). Baker et al have found that adults with dementia can benefit from multisensory stimulation or traditional activities, with improvement in both their emotional and social responses ( Baker et al, 2001 , 2003 ).…”

Olfactory dysfunction can indicate early cognitive decline and is associated with dementia symptoms. We developed an olfactory-based sensory stimulation program and investigated its effects on cognition and emotion, and board game training were used as a comparison. In this parallel design pilot study, 30 participants with mild to moderate dementia were equal randomly assigned to the control (CONT), olfactory stimulation with cognitive training (OS), and board game (BG) groups. Two participants were withdrawn from CONT and OS groups, respectively. The intervention was a 12-week program with one 30-min session twice a week. We employed a blood-based biomarker technique and several cognitive and psychological tests to measure basal and after-intervention values. No significant differences were observed between the groups after intervention, as measured using the Mini-Mental State Examination, Loewenstein Occupational Therapy Cognitive Assessment (LOTCA), Top International Biotech Smell Identification Test, and Geriatric Depression Scale (GDS). The results showed that the OS group had a lower plasma Tau level than the other groups following intervention, whereas the CONT group had a significantly increased plasma amyloid ß1-42 level. OS participants had a lower concentration ratio of plasma Tau and amyloid Aß1-42 and showed more stable or improved cognition, olfactory function, and mood state. Both the OS and BG groups had a higher percentage of participants with stable or improved cognition and emotion. Taken together, these results suggest that olfactory-based sensory stimulation can be a beneficial intervention for patients with dementia.Clinical trial registration[Clinicaltrials.gov], identifier [NCT05168098].

INTRODUCTIONBehavioral and psychological symptoms in dementia (BPSD) are dynamic phenomena with a high amount of intraindividual variability. We applied a multilevel framework to identify subsyndromes (between‐person factors) that represent clinically relevant profiles of BPSD and identify symptom clusters (within‐person factors) that represent contextually driven daily symptom experiences.METHODSThis study used an intensive longitudinal design in which 68 co‐residing family caregivers to persons living with dementia were recruited to proxy report on their care recipient's daily symptom experiences of 23 different BPSD for eight consecutive days (n = 443 diaries). A multilevel exploratory/confirmatory factor analysis was used to account for nested data and separate within‐person variances from between‐level factor estimates.RESULTSExploratory factor analysis identified a 4‐between 3‐within factor structure based on fit statistics and clinical interpretability.DISCUSSIONThis study offers major methodological and conceptual advancements for management of BPSD within Alzheimer's disease and related dementias by introducing two related but distinct concepts of subsyndromes and symptom clusters.Highlights Because behavioral and psychological symptoms of dementia (BPSD) are dynamic temporal phenomenon, this introduces measurement error into aggregate group‐level estimates when trying to create subsyndromes. We propose a multilevel analysis to provide a more valid and reliable estimation by separating out variance due to within‐person daily fluctuations. Using a multilevel exploratory factor analysis with intensive longitudinal data, we identified distinct and meaningful groups of BPSD. The four factors at the between‐person level represented subsyndromes that are based on how BPSD co‐occurred among persons with Alzheimer's disease (AD). These subsyndromes are clinically relevant because they share features of established clinical phenomena and may have similar neurobiological etiologies. We also found three within‐person factors representing distinct symptom clusters. They are based on how BPSD clustered together on a given day for an individual with AD and related dementias. These clusters may have shared environmental triggers.
