Using Complementary and Alternative Medicine to Treat Pain and Agitation in Dementia: A Review of Randomized Controlled Trials from Long-Term Care with Potential Use in Critical Care

Perspectives on approaching pain management in patients with dementia

This paper presents a review of the latest literature and guidance regarding the assessment and management of pain in older adults with dementia. The size and nature of the problem will be presented, in terms of the increasing aging population across the globe and potential for a significant increase in adults with dementia, along with the reduction in younger counterparts who will be available to provide care in the future. We will present the latest recommendations regarding how to assess pain and which tools are recommended for use underpinned by the strongest evidence. Finally, we will present the findings of the latest national (UK) guidelines for the management of pain. Recommendations will be made for future research and clinical practice.

Assess of Combinations of Non-Pharmacological Interventions for the Reduction of Irritability in Patients with Dementia and their Caregivers: A Cross-Over RCT

Introduction: Dementia is a very common disorder that affects people over 65 years old all over the world. Apart from the cognitive decline, Behavioral and Psychological Symptoms of Dementia (BPSD) are a crucial matter in dementia, because they affect up to 90% of the patients during the course of their illness. Irritability has been found to be a common BPSD and one of the most distressing behaviors for the caregivers. The aim of the current study was to explore the efficacy of a combination of non-pharmacological interventions to treat irritability. Methods: Sixty patients with different types and stages of dementia with irritability were participated in a cross-over RCT. Three non-pharmacological interventions were used; (a) Validation Therapy (VT)/Psycho-educational program, (b) Aromatherapy/massage and (c) Music Therapy (MT). The study assessed the three non-pharmacological interventions in order to find the most effective combination of the interventions. This study did not compare pharmacological and non-pharmacological treatments. The interventions lasted for five days. There was no drop-out rate. All patients were assessed at baseline using Mini Mental State of Examination (MMSE), Addenbrooke’s Cognitive Examination Revised (ACE-R), Geriatric Depression Scale (GDS), Functional Rating Scale for symptoms in dementia (FRSSD), and Neuropsychiatric Inventory (NPI) (sub questions for irritability). Only NPI used for the assessment after each intervention. The analyses used categorical variables, Wilcoxon signed-rank test, Chi-square test and z value score. Results: The most effective combination of non-pharmacological interventions was Aromatherapy/massage (p = 0.003)-VT plus Psycho-educational program (p = 0.014) plus MT (p = 0.018). The same combination was the most effective for the caregivers’ burden, too (p = 0.026). Conclusions: The above combination of non-pharmacological interventions can reduce irritability in patients with dementia and caregivers’ burden.

The role of plant-based products in the prevention of neurological complications

BACKGROUND

Neurological complications are most likely to be fatal and cause loss of ability to function or care for self. These include Alzheimer's disease and cognitive impairment. The main aim of the review is to determine the effects of various drugs and their cognitive risk with the need to opt for herbal therapy as an adjuvant in treating neurological conditions like Alzheimer's disease with lesser-known side effects. The Methodology: Involved a detailed literature survey which was performed through an online database, such as Science Direct, Google Scholar, Scopus, Cochrane, and PubMed. The study included randomized trials and original research conducted by herbal supplements on animal models to assess expression of upregulation of signalling pathways. Various studies involved in treating dementia, neurological disorders, Alzheimer disease, cognitive dysfunction were included.

RESULTS

Found that various studies involved plant-based products were showing improvement in prevention of disease and signalling pathways with lesser-known side effects.

CONCLUSION

It was observed that plant-based products play a major role in the prevention of neurological complications. Herbal medicines could most suitably prevent Alzheimer's risk with less known side effects in contrast with the existing treatment patterns. However, to improve the utility of herbal medicines, more evidences from in vitro, in vivo, and clinical trials need to be addressed.

Population-Focused Approaches for Proactive Chronic Pain Management in Older Adults

Chronic pain, and the ethical management thereof, is the single most imperative health issue of this decade. Although a growing majority of individuals with chronic pain are middle-aged, the largest proportion of sufferers are older adults. Shifting tides in practice and research have led to population-focused approaches to pain management; however, the practice of many healthcare providers remains reactive and individualistic, limiting the discovery and implementation of long-term solutions for pain management in older adults. Yet, nurses and other health professionals have an opportune position to provide expert pain care by proactively providing evidence-based care for patients systematically. The purpose of this article is to stimulate discussion on three paradigms important to population-focused pain management: (1) prevention; (2) restoration and rehabilitation; and (3) palliation, which are in line with current national policy initiatives for improving patients' care experience, improving overall health and quality of life, and reducing associated health care costs.

Senior WISE intervention: Gender differences in bodily pain and trait anxiety

PURPOSE

In this secondary analysis we tested whether 12 h of Senior WISE (Wisdom Is Simply Exploration) memory or health training with older adults would produce better outcomes by gender in perceptions of anxiety and bodily pain and whether the effects of the Senior WISE training on pain were mediated by anxiety.

DESIGN

An implemented Phase III randomized clinical trial with follow up for 24 months in Central Texas. The sample was mostly female (79%), 71% Caucasian, 17% Hispanic, and 12% African American with an average age of 75 and 13 years of education.

RESULTS

The effects of the memory intervention on anxiety were consistent across time, with effects present for males but not females at post-treatment and end-of-study. Although males had more anxiety in the health promotion group, the memory training reduced males' anxiety such that no gender difference was present in this group. The Senior WISE intervention reduced pain for both males and females at post-intervention but not at end-of-study. Although gender differences did not depend on the treatment group for pain, females reported somewhat, but not significantly, less pain at post-treatment and end-of-study. Mediation analysis indicated that, for males, the memory intervention indirectly affected pain at post-treatment, in part, by reducing anxiety, which lowered pain. However, at end-of-study, no indirect effect was present. Males responded to memory training. Training tailored to gender may increase the efficacy of the programs and "buy-in" from male participants, especially if tailored to anxiety and pain.

Use of complementary medicines and lifestyle approaches by people living with dementia: Exploring experiences, motivations and attitudes

BACKGROUND

Lack of effective treatments for chronic conditions is associated with high rates of complementary medicine (CM) use. However, little is known about CM use for dementia.

AIMS AND OBJECTIVES

The aim of this study was to explore the experiences, motivations, and attitudes towards CM use by people living with dementia in an Australian setting.

DESIGN

This study had a qualitative research design; quantitative demographic information was also collected.

METHODS

In-depth interviews were conducted with people living with dementia and their caregivers (N = 18). A thematic (inductive) analysis approach was taken to interpret data.

RESULTS

Three in four participants used CM for dementia, spending ~AUD$100/month (USD$70/month). Within three overarching themes, a range of sub-themes was identified: (1) CM knowledge and use: people living with dementia and caregivers understanding of CM, types of CM used, and CM usage patterns; (2) Self-determined reasons for use/non-use: maintain or improve quality of life, hope, management of dementia symptoms, level of awareness, willingness and evidence, perceptions on efficacy and safety of CM, experiences of conventional medicine, and holistic approach to wellness; (3) External determinants of use: information on CM, relationship influences on CM use, and experiences with General Practitioners (GPs) and CM.

CONCLUSION

Findings highlight that CM use is widespread and positively viewed by people living with dementia and their caregivers. Decisions regarding CM use were based on personal opinions. Findings have important implications for conversations with health professionals regarding CM use by people living with dementia to improve communication, health literacy, and reduce the risk of adverse effects through polypharmacy.

IMPLICATIONS FOR PRACTICE

This study showed that CM is a valued approach for dementia management by people living with dementia, their families, and healthcare providers. Future international research is required to evaluate the efficacy and safety of these approaches and promote accurate advice in nursing care.

Complementary and alternative medicines for behavioral and psychological symptoms of dementia: A protocol of overview of systematic reviews

BACKGROUND

Dementia is causing a huge medical and socioeconomic burden. Along with strategies to delay cognitive decline in dementia, behavioral and psychological symptoms of dementia (BPSD) are major contributing factor to the burden of dementia, and have been an important clinical issue for successful management of dementia. However, pharmacological strategies such as antipsychotics raise concerns in terms of risk-to-benefit ratio in managing BPSD. Therefore, there is a need for an effective and safe alternative in BPSD management. From this point of view, various complementary and alternative medicines (CAMs) are attracting attention in BPSD management. Therefore, the overview will make it possible to evaluate the feasibility of using CAM as a potential treatment strategy for BPSD in terms of evidence-based medicine.

METHODS AND ANALYSIS

Comprehensive searching will be performed in 13 bibliographic databases from their inception dates to November 2021. Systematic reviews and/or meta-analyses that examined the effectiveness and safety of CAM modalities including herbal medicine, acupuncture, acupressure, aromatherapy, meditation, and relaxation on BPSD, will be included. The methodological quality of included reviews will be assessed by using the A MeaSurement Tool to Assess systematic Reviews-2. Two independent researchers will conduct study search, study selection, data extraction, and quality assessment processes.

RESULTS

The results of overview will be disseminated by the publication of a manuscript in a peer-reviewed journal or presentation at a relevant conference.

CONCLUSION

The findings of this overview will help to solve the major public health problem related to dementia, and will provide patients with dementia, their caregivers, clinicians, and health policy makers credible evidence in mitigating the burden of dementia.

ETHICS AND DISSEMINATION

As this protocol is for an overview of systematic reviews and meta-analyses, ethical approval is not required.

Integrative therapies in intensive care units: A scoping review

AIM

We reviewed literature describing the incorporation of integrative therapies in intensive care units. We aimed to elicit an overall picture of research and find existing knowledge gaps on this topic.

DESIGN

We conducted a scoping review guided by Arksey and O'Malley's methodological framework and were guided by the PRISMA-ScR Checklist.

METHODS

Various databases were searched for relevant literature. English language articles published between 1999 and 2019 were retrieved. Data were extracted based on sample, sample size, methodology, findings and implications for practice.

RESULTS

From 275 studies retrieved, 30 were included, based on the inclusion criteria. Three key themes related to integrative therapies in intensive care units emerged from the literature: 1) general information on integrative therapies; 2) interventions using integrative therapies; and 3) perceptions and attitudes of nurses on integrative therapies. Positive outcomes were observed in ICUs, and nurses showed positive attitudes towards using integrative therapies.

Experimentally evoked pain in Alzheimer's disease

BACKGROUND

Pain continues to be underrecognized and undertreated in Alzheimer's disease (AD) while existing guidance about pain assessment and management in dementia is not widespread. Brain regions involved in pain processing and modulation are damaged during AD, and the pain experience in AD is not well understood. Experimental pain studies using psychophysics can further our understanding of the pain experience in AD, which may lead to improved assessment and management of pain in people living with AD.

OBJECTIVE

A systematic review was conducted to explicate the current understanding of experimentally evoked pain in AD from primary research using psychophysical methods.

DATA SOURCES

Peer-reviewed publications were found via PubMed, CINAHL, and PsycINFO. A total of 18 primary research, peer-reviewed full articles that met inclusion criteria were included, representing 929 total participants.

CONCLUSIONS

Experimentally evoked pain in people with AD demonstrates that despite cognitive impairment and a reduced ability to effectively communicate, individuals with AD experience pain similar to or more unpleasant than cognitively intact older adults. This may mean amplified pain unpleasantness in people with AD.

IMPLICATIONS FOR PRACTICE

Our current best practices need to be widely disseminated and put into clinical practice. Self-report of pain continues to be the gold standard, but it is ineffective for noncommunicative patients and those unable to understand pain scales or instructions because of memory/cognitive impairment. Instead, pain treatment should be ethically initiated based on patient reports and behaviors, caregiver/surrogate reports, review of the medical record for painful conditions, analgesic trials, and regular reassessments.

Determining the impact of age and sex on the psychophysical and neurophysiological response to thermal pain across the adult lifespan

AIMS

Determine sex- and age-associated psychophysical and neurophysiological differences in the processing of pain across the adult lifespan.

DESIGN

Preliminary, exploratory, cross-sectional study.

METHODS

Using psychophysics (to measure intensity and unpleasantness) and functional magnetic resonance imaging blood oxygenation level dependent methods (to measure stimulus-evoked brain activation), we will examine sex- and age-associated differences in thermal pain processing and their underlying neurophysiology in a broad range of healthy adults (ages 30-89). We will acquire resting state functional connectivity data for secondary analyses exploring whether resting state connectivity predicts psychophysical and neurophysiological responses to thermal pain. To examine the effects of altered blood flow, we will acquire resting-state arterial spin labeling magnetic resonance imaging data to quantify resting cerebral blood flow. We will interpret findings in the context of a proposed neural model of pain, ageing, and sex. Study funding was received in June of 2014. Ethical approval was obtained from the Vanderbilt University IRB prior to study initiation.

CONCLUSION

Exploring the biological reasons for age- and sex-associated differences in pain processing will increase our understanding of pain in older adults. The paucity of neurobiological evidence to support best practice pain management in older adults places these individuals at risk for poor pain management.

IMPACT

Poorly treated pain in older adults is a critical public health problem associated with a poor quality of life and increased healthcare costs. Understanding how age and sex have an impact on central processing of pain across the lifespan is a critical step toward improving personalized pain medicine.

Are Chronic Pain Patients with Dementia Being Undermedicated?

In dementia, neuropathological changes alter the perception and expression of pain. For clinicians and family members, this knowledge gap leads to difficulties in recognizing and assessing chronic pain, which may consequently result in persons with dementia receiving lower levels of pain medication compared to those without cognitive impairment. Although this situation seems to have improved in recent years, considerable geographical variation persists. Over the last decade, opioid use has received global attention as a result of overuse and the risk of addiction, while the literature on older persons with dementia actually suggests undertreatment. This review stresses the importance of reliable assessment and the regular evaluation and monitoring of symptoms in persons with dementia. Based on current evidence, we concluded that chronic pain is still undertreated in dementia.

Pain-Reducing Effects of Physical Therapist-Delivered Interventions: A Systematic Review of Randomized Trials Among Older Adults With Dementia

BACKGROUND AND PURPOSE

Pain is common among older adults with dementia. There are nonpharmacological options for managing pain in this population. However, the effects of physical therapist-delivered interventions have not been summarized. The purpose of this systematic review was to summarize the literature on physical therapist-delivered interventions in randomized trials for reducing pain among older adults with dementia.

METHODS

A systematic search of MEDLINE/PubMed, CINAHL, PsycINFO, and Web of Science was conducted for randomized trials of pain management in individuals 60 years or older with medically diagnosed dementia of any severity. Included studies addressed the effects of nonpharmacological physical therapist-delivered interventions on pain outcomes. Pain outcomes included patient or caregiver self-report, observational or interactive measures. Independent reviewers extracted relevant data and assessed methodological quality using the PEDro scale.

RESULTS AND DISCUSSION

Three studies (total = 222 participants; mean age range = 82.2-84.0 years; 178 [80.2%] females) met inclusion criteria. PEDro scores ranged from 4 to 8/10. Interventions included passive movement and massage. Pain outcomes included the observational measures Pain Assessment Checklist for Seniors with Limited Ability to Communicate (PACSLAC), Pain in Advanced Dementia (PAINAD), and Doloplus-2 Scale. Passive movement did not show better results when compared with no treatment, while massage showed pain-reducing effects in 1 study compared with no treatment.

CONCLUSIONS

The evidence supporting pain-reducing physical therapy interventions for patients with dementia is limited. There is a clear gap in knowledge related to evidence-based physical therapy for managing pain in this population. Future studies should examine active physical therapist-delivered interventions and utilize interactive pain measures.

Calming Effects of Touch in Human, Animal, and Robotic Interaction-Scientific State-of-the-Art and Technical Advances

Small everyday gestures such as a tap on the shoulder can affect the way humans feel and act. Touch can have a calming effect and alter the way stress is handled, thereby promoting mental and physical health. Due to current technical advances and the growing role of intelligent robots in households and healthcare, recent research also addressed the potential of robotic touch for stress reduction. In addition, touch by non-human agents such as animals or inanimate objects may have a calming effect. This conceptual article will review a selection of the most relevant studies reporting the physiological, hormonal, neural, and subjective effects of touch on stress, arousal, and negative affect. Robotic systems capable of non-social touch will be assessed together with control strategies and sensor technologies. Parallels and differences of human-to-human touch and human-to-non-human touch will be discussed. We propose that, under appropriate conditions, touch can act as (social) signal for safety, even when the interaction partner is an animal or a machine. We will also outline potential directions for future research and clinical relevance. Thereby, this review can provide a foundation for further investigations into the beneficial contribution of touch by different agents to regulate negative affect and arousal in humans.

Adults' Self-Management of Chronic Cancer and Noncancer Pain in People with and Without Cognitive Impairment: A Concept Analysis

AIM

To report a concept analysis of adult self-management of chronic pain.

BACKGROUND

Self-management of chronic pain has received increasing attention in the clinical research literature. Although with only limited conceptual work. Despite the pervasiveness of pain in adults, there has been a lack of conceptual work to elucidate meaning of adult's self-management of chronic pain.

DESIGN

Concept Analysis.

METHOD

Rodgers (2000) evolutionary approach of concept analysis was used to systematically analyze 44 articles from different databases. Only 12 articles used the concept of chronic pain self-management. Data were extracted using standardized forms and analyzed using thematic analysis.

RESULTS

This concept analysis identified six attributes of adult self-management of chronic pain: (1) multimodal interventions; (2) patient-provider relationship; (3) goal setting; (4) decision making; (5) resource utilization; and (6) chronic pain problem solving.

Palliative Care in Advanced Dementia

Dementia syndrome is common and expected to increase significantly among older people and characterized by the loss of cognitive, psychological and physical functions. Palliative care is applicable for people with dementia, however they are less likely to have access to palliative care. This narrative review summarizes specifics of palliative care in advanced dementia. Most people with advanced dementia live and die in institutional care and they suffer a range of burdensome symptoms and complications. Shortly before dying people with advanced dementia suffer symptoms as pain, eating problems, breathlessness, neuropsychiatric symptoms, and complications as respiratory or urinary infections and frequently experience burdensome transitions. Pharmacological and nonpharmacological interventions may reduce symptom burden. Sensitive observation and appropriate assessment tools enable health professionals to assess symptoms and needs and to evaluate interventions. Due to lack of decisional capacity, proxy decision making is often necessary. Advanced care planning is an opportunity establishing values and preferences and is associated with comfort and decrease of burdensome interventions. Family carers are important for people with advanced dementia they also experience distress and are in need for support. Recommendations refer to early integration of palliative care, recognizing signs of approaching death, symptom assessment and management, advanced care planning, person-centered care, continuity of care, and collaboration of health care providers.

Pain in dementia

The ageing revolution is changing the composition of our society with more people becoming very old with higher risks for developing both pain and dementia. Pain is normally signaled by verbal communication, which becomes more and more deteriorated in people with dementia. Thus, these individuals unnecessarily suffer from manageable but unrecognized pain. Pain assessment in patients with dementia is a challenging endeavor, with scientific advancements quickly developing. Pain assessment tools and protocols (mainly observational scales) have been incorporated into national and international guidelines of pain assessment in aged individuals. To effectively assess pain, interdisciplinary collaboration (nurses, physicians, psychologists, computer scientists, and engineers) is essential. Pain management in this vulnerable population is also preferably done in an interdisciplinary setting. Nonpharmacological management programs have been predominantly tested in younger populations without dementia. However, many of them are relatively safe, have proven their efficacy, and therefore deserve a first place in pain management programs. Paracetamol is a relatively safe and effective first-choice analgesic. There are many safety issues regarding nonsteroidal anti-inflammatory drugs, opioids, and adjuvant analgesics in dementia patients. It is therefore recommended to monitor both pain and potential side effects regularly. More research is necessary to provide better guidance for pain management in dementia.

A Scoping Review of Dementia Symptom Management in Persons with Dementia Living in Home-based Settings

Background

A large proportion of our older adults live with Alzheimer's Disease and Related Dementias and the number of those diagnosed in the future is expected to increase dramatically as the population ages. Persons with dementia bring unique healthcare challenges due to the manifestation of behavioral and psychological symptoms associated with the disease. The lack of geriatric clinicians as well as a properly trained non-geriatric specialist workforce capable of addressing the symptoms persons with dementia exacerbate the challenge of providing effective care. Pharmacological interventions are contraindicated for treatment of most behavioral psychological symptoms of dementia (BPSD). The Centers for Medicare and Medicaid Services now requires that nonpharmacological interventions be used as a first-line treatment. It has not been determined what nonpharmacological intervention for BPSD are most effective and what the infrastructure would entail for such interventions for PWD living at home.

Purpose of Review

The purpose of this study is to examine the literature focusing on interventions aimed towards managing persons' symptoms of dementia living in home-based settings. A scoping review examining the literature published on this topic over the last three years was conducted.

Recent Findings

One thousand twenty four articles were found, of which nine met inclusion criteria. Five articles used occupational based therapy, two used exercise therapy and one article was found utilizing aromatherapy and music therapy.
