Use of multisensory stimulation interventions in the treatment of major neurocognitive disorders

Abstract

OBJECTIVE: Behavioral and psychological symptoms of dementia (BPSD) are a heterogeneous constellation of non-cognitive symptoms and behaviours that can cause significant patient distress and present complex management challenges. Behavioural and pharmacological treatments are used to decrease the symptoms, preserve function and increase quality of life. In the treatment of individuals with a major neurocognitive disorder, non-pharmacological interventions are often preferred as first-line treatment over pharmacological interventions, which often have modest efficacy, notable side effects and significant risks. Multisensory stimulation (MSS) interventions have become increasingly popular in the treatment of BPSD, particularly with disease progression. The objective of this review paper is to provide a brief overview of the types of MSS interventions currently used in the treatment of major neurocognitive disorders. METHODS: Searches for papers published in this area were conducted using PubMed and the Web of Science Core Collection. The searches were done for the period covering the past 20 years, and key phrases used were "multisensory stimulation for treatment of BPSD," "multisensory stimulation for treatment of major cognitive disorders," "multisensory stimulation for treatment of dementia" and "multisensory stimulation for treatment of neurodegenerative disorders." RESULTS: Multisensory environments, multisensory tools and multisensory group therapies are discussed. There is growing support for the use of MSS interventions to improve mood, behaviour and quality of life in seniors with dementia and BPSD. However, currently the utilization of these interventions is highly variable and strong evidence for their use is limited. CONCLUSION: MSS interventions in the form of multisensory environments, tools and group therapies present tremendous potential as first-line treatments or as adjuncts to pharmacological interventions in the treatment of major neurocognitive disorders. However, the body of quality evidence that currently exists is limited. A lack of evidence does not necessarily mean a lack of efficacy, and there is a pressing need for studies with improved power and study design to determine the effectiveness of specific MSS interventions and to ascertain for whom they may be most beneficial.

Can you hear the Colour? Towards a Synaesthetic and Multimodal Design Approach in Virtual Worlds

“…While there is limited research in VR for explicitly embedding 'novel' multimodal approaches, there is a good body of research that acknowledges the value of multisensory design in interventions that support healthcare and promote wellbeing. Multisensory VEs have been used to reduce stress levels (Putrino et al, 2020), have shown potential for improved quality of life for people with dementia (Cheng, Baker & Dursun, 2019;Sánchez et al, 2013) and provided interventions for anxiety symptoms (Rajasekaran et al, 2011) and the profoundly disabled (Brooks, 2021). Although multisensory design has been embedded in VR/MR there is limited research focus on embedding or facilitating 'fused' sensory experiences, for example, synaesthetic approaches.…”

Non-Drug Treatment Methods Used in Alzheimer Patients

“…Çoklu duyusal uyaran yöntemi, demanslı bireylerin bilişsel ve ruhsal belirtilerini azaltmak ve iyilik halini sürdürmek amacıyla görsel, dokunsal, işitsel veya koku uyaranları yoluyla iki veya daha fazla uygulamanın aynı anda kullanılması sonucu ortaya çıkan bir müdahale yöntemidir (Cheng et al, 2019). Bu yöntemin uygulanması için kullanılan yeni tekniklerden biri olan Snoezelen, 1970'lerde Hollanda'da ilk olarak öğrenme güçlüğü çeken bireylerde uygulanmıştır.…”

Conceptul de mediu construit activator pentru persoane vârstnice cu tulburări neurocognitive într-o perspectivă interdisciplinară

“…Ca spații activatoare putem cataloga spațiile proiectate pentru a stimula memoria senzorială și pe cea procedurală, care vor antrena, la rândul lor, memoria episodică și reconectarea cu sine, cu istoria personală și cu prezentul. Aici putem include și spațiile care mimează domenii ale orașului și satului din tinerețe (Baxter, 2018;Kotecki, 2018;Keenan, 2014), mediile multisenzoriale (Snoezelen.2020;Cheng, 2019).…”
