Analysis of characteristics affecting instrumental activities of daily living in Parkinson's disease patients without dementia

Self-management interventions involving care partners of individuals with neurodegenerative movement disorders: a scoping review

PURPOSE

This scoping review aims to explore the components of existing self-management interventions involving care partners of individuals with neurodegenerative movement disorders (NMDs). The review seeks to describe the key components, categorize different types and approaches using the PRISMS taxonomy.

METHODS

A comprehensive search was conducted in five databases: SCOPUS, CINAHL, MEDLINE, PsycINFO, and Embase. Articles were included if they involved self-management interventions for adult care partners of individuals with NMDs. Data extraction was guided by the PRISMS, TEDSS and TIDieR frameworks, focusing on intervention characteristics, components, outcome measures, theories, and formats.

RESULTS

The review included 34 articles, with most interventions targeting Parkinson's Disease. Interventions varied widely in structure, delivery format, setting and content. Psychological and internal strategies were the most frequently utilized components. Notably, only 11 interventions were specifically designed for care partners.

CONCLUSION

This scoping review provides key insights into the diverse elements of self-management interventions for NMDs, including their structure, delivery format, and components. It highlights the lack of comprehensive dyadic interventions that support both individuals with NMDs and their care partners. Future research should explore the integration of personalization, communication training and dyadic coping strategies.

The feasibility of a self-regulation and mental imagery programme to enhance everyday functioning for people with Parkinson's disease: study protocol

BACKGROUND

Less dopaminergic neurons in people with Parkinson's disease result in a reliance on a slow and energy-intensive control, restricting their ability to complete routine everyday activities. Self-regulation takes an active learning approach to rehabilitation by enhancing the person's self-awareness and encourages self-reflection to overcome problems. Mental imagery assists the person to focus attention on the requirements for the task, making it a goal-directed action and allowing for faster movements. There is a growing body of evidence to support the use of self-regulation and mental imagery in rehabilitation to maintain or improve the performance of everyday activities for people with a neurological condition.

METHODS

A prospective pilot study using a single-group, pre-test and posttest design will test the feasibility and acceptability of a self-regulation and mental imagery programme to enhance performance of everyday activities and motor and cognitive function in people with Parkinson's disease. People who have a diagnosis of Parkinson's disease with mild-to-moderate severity and intact attention, comprehension and short-term memory will be recruited. The participants will receive a 6-week programme with one therapist-led session, a home programme and a telephone call each week. The programme uses self-regulation through a step-based problem-solving process and mental imagery to assist in movement planning. Appropriate rehabilitation strategies are used as solutions to tackle problems experienced, impacting performance in everyday activities. The attendance rate will be recorded to indicate the feasibility. A questionnaire will be administered post-intervention to collect feedback on programme acceptability. Patient outcomes will include Barthel index, Lawton Instrumental Activities of Daily Living Scale, Canadian Occupational Performance Measure and Timed Up and Go test. Trail Making Test and Montreal Cognitive Assessment will be collected pre- and post-intervention.

DISCUSSION

The programme aims to combine the metacognitive strategies of self-regulation and mental imagery to enable individuals with Parkinson's disease to improve the performance of everyday activities. If feasible, the programme has the potential to be further tested in a randomised controlled trial and benefit people with Parkinson's disease by enhancing their performance required in independent community living.

Cognition and Activity of Daily Living Function in people with Parkinson's disease

The ability to perform activities of daily living (ADL) function is a multifaceted construct that reflects functionality in different daily life situations. The loss of ADL function due to cognitive impairment is the core feature for the diagnosis of Parkinson's disease dementia (PDD). In contrast to Alzheimer's disease, ADL impairment in PD can be compromised by various factors, including motor and non-motor aspects. This narrative review summarizes the current state of knowledge on the association of cognition and ADL function in people with PD and introduces the concept of "cognitive ADL" impairment for those problems in everyday life that are associated with cognitive deterioration as their primary cause. Assessment of cognitive ADL impairment is challenging because self-ratings, informant-ratings, and performance-based assessments seldomly differentiate between "cognitive" and "motor" aspects of ADL. ADL function in PD is related to multiple cognitive domains, with attention, executive function, and memory being particularly relevant. Cognitive ADL impairment is characterized by behavioral anomalies such as trial-and-error behavior or task step omissions, and is associated with lower engagement in everyday behaviors, as suggested by physical activity levels and prolonged sedentary behavior. First evidence shows that physical and multi-domain interventions may improve ADL function, in general, but the evidence is confounded by motor aspects. Large multicenter randomized controlled trials with cognitive ADL function as primary outcome are needed to investigate which pharmacological and non-pharmacological interventions can effectively prevent or delay deterioration of cognitive ADL function, and ultimately the progression and conversion to PDD.

Assessment of cardiorespiratory fitness in Chinese patients with early to mid-stage Parkinson's disease

PURPOSE

To evaluate cardiorespiratory fitness in patients with early to mid-stage Parkinson's disease by cardiopulmonary exercise test (CPET) on a stationary cycle ergometer.

METHODS

To compare the differences in each index of the cardiopulmonary exercise test between the two groups of subjects; general data such as disease duration, medication use and exercise habits were also collected.

RESULTS

(1) Finally, 36 Parkinson's disease patients and 12 healthy controls successfully completed the cardiopulmonary exercise test without any adverse events. (2) The V'O2peak, Metspeak, RERpeak, MVVpeak, Wpeak, HRpeak, HRpeak/pre, percentage of HRR-1 min decay > 12 bpm, SBPpeak in the Parkinson's disease group were lower than those in the control group (p < .05, each). Detailed data: V'O2peak (15.7 ± 4.5vs21.5 ± 3.6 ml/kg/min, p < .01), Metspeak (4.5 ± 1.3 vs 6.1 ± 1.0, p < .01), RERpeak (1.04 ± 0.10 vs 1.15 ± 0.10, p = .001), MVVpeak (37.22 ± 11.58 vs 53.00 ± 16.85L/min, p = .009), Wpeak (49.17 ± 29.72 vs 49.17 ± 29.72W, p < .01), HRpeak (111.08 ± 16.67 vs 111.08 ± 16.67bpm, p < .01), HRpeak/pre (71.19 ± 10.06 vs 96.00 ± 21.13, p = .002), percentage of HRR-1min decay > 12bpm (33.3% vs 100%, p < .01), systolic blood pressure (155.81 ± 31.83 vs 175.83 ± 17.84 mmHg, p = .01). (3) Divided Parkinson's disease patients into high V'O2peak group (V'O2peak ≥ 15 mL/kg/min) and low V'O2peak group (V'O2peak < 15 mL/kg/min). The age of patients, Hoehn-Yahr grade and incidence of symptom fluctuation in high V'O2peak group were lower (p < .05, respectively), percentage of males and percentage of HRR-1 min decay > 12 bpm were higher (p < .05, respectively); p < .05 is considered a statistically significant difference. Detailed data: age of patients(61.05 ± 6.93 vs 68.57 ± 7.99 years, p = .005), Hoehn-Yahr grade(1.75 ± 0.48 vs 2.18 ± 0.64, p = .028), incidence of symptom fluctuation (59.1 vs 92.9%, p = .03), percentage of males (77.7 vs 42.9%, p = .041), percentage of HRR-1 min decay > 12 bpm (50 vs 7.1%, p = .008).

CONCLUSIONS

Cardiopulmonary exercise test was safe to perform and the cardiorespiratory fitness is significantly reduced in patients with early and middle stage Parkinson's disease. Patients with Parkinson's disease presented blunted heart rate and systolic blood pressure responses to exercise test. Females, older age, fluctuating symptoms, high H-Y staging and higher activities of daily living may be associated with lower oxygen uptake.

Frailty and Parkinson's disease: the role of diabetes mellitus

Parkinson's disease (PD) is a chronic neurodegenerative disease associated with a progressive loss of dopaminergic neurons, clinically characterized by motor and non-motor signs. Frailty is a clinical condition of increased vulnerability and negative health outcomes due to the loss of multiple physiological reserves. Chronic hyperglycemia and insulin resistance, which characterize diabetes mellitus (DM), have been reported to alter dopaminergic activity, increase the risk of PD, and influence the development of frailty. Even though diabetes may facilitate the development of frailty in patients with PD, this relationship is not established and a revision of the current knowledge is necessary. Furthermore, the synergy between DM, PD, and frailty may drive clinical complexity, worse outcomes, and under-representation of these populations in the research. In this review, we aimed to discuss the role of diabetes in the development of frailty among patients with PD. We summarized the clinical characteristics and outcomes of patients with concomitant DM, PD, and frailty. Finally, interventions to prevent frailty in this population are discussed.

Validation of the Italian version of the Parkinson's Disease- Cognitive Functional Rating Scale

A key distinguishing factor between mild cognitive impairment (MCI) and dementia in Parkinson's disease (PD) lies in the notable decrease in functioning due to cognitive impairment. The Parkinson's Disease-Cognitive Functional Rating Scale (PD-CRFS) was developed to assess functional limitations caused by cognitive impairment, while reducing the influence of motor impairment. The aim of this multicenter study was to (i) validate the Italian version of the PD-CFRS in PD, (ii) determine optimal cut-off scores for detecting MCI and dementia in PD, (iii) compare its performances with the most established functional assessment tool (IADL). Six hundred and sixty nine PD participants were recruited from 4 Italian Movement Disorders centers (Venice, Milan, Gravedona, and Salerno). They underwent Level-II cognitive evaluation, which resulted in 282 PD-NC, 310 PD-MCI, and 77 PDD. The PD-CFRS's psychometric and clinimetric properties, applicability, and responsiveness were analyzed. The PD-CFRS showed high acceptability. Floor and ceiling effects were acceptable. It also displayed strong internal consistency (Cronbach's α = 0.738), and test-retest reliability (ICC = .854). The PD-CFRS demonstrated higher coefficient of variation to detect dysfunction in PD-MCI patients in comparison to the IADL scale (PD-CFRS 96% vs IADL 22.5%). Convergent validity with the IADL was r = - 0.638 and - 0.527 in males and females, respectively. PD-CFRS total score negatively correlated with global cognition (MoCA corrected score r = - 0.61; p < 0.001). A cut-off score > 6.5 identified PDD with a sensitivity of 90% and specificity of 88% (AUC = .959). A cut-off value of > 1 detected PD-MCI with a sensitivity of 68% and specificity of 69% (AUC = .695). The Italian version of the PD-CFRS demonstrated to be an easy, valid and reliable tool that properly captures functional impairment due to cognitive decline in PD. It also proved to be particularly effective in the advanced stages of PD, and would be a useful support for the diagnosis of PD-MCI and PDD.

The importance of a multidisciplinary approach to improve the life quality for patients with Parkinson's disease

Parkinson's disease is defined as a complex degenerative neurological disease with progressive evolution, which is part of motor system of the brain disorders, being the second degenerative disease as a frequency after Alzheimer's disease. It is characterized by tremor when muscles are at rest (rest tremor), increased muscle tone (stiffness), slow voluntary movements and difficulty maintaining balance (postural instability). Occupational therapy helps Parkinson's patients im-prove their ability to perform daily tasks. The intervention consists in assisting patients in deve-loping a self-care routine, taking into account the limitations of functional mobility, encoura-ging patients to maintain maximum function of daily activities for as long as possible, learning adaptive techniques to reduce tremor. Materials and methods. The devices used for this purpose are commercially available but they are quite expensive, which is why we wanted to make devi-ces made of material as cheap and affordable as possible. Some of the devices can be successfully made of material that every person has in their home. We also took into account the variant of making them without the need to use complicated tools and devices that are not available to pa-tients. Starting from these premises, we thought and made in our occupational therapy laborato-ry various devices designed to offer patients a variety of techniques and exercises and also a fle-xible work environment. On a pallet plate we fixed a series of elements such as zippers, snap button, hook-and-eye closure, systems that patients use on a regular basis. We also manufactu-red a device designed to help patients with household chores such as dish washing. The device is provided at one end with a washing sponge, its handle being a detergent tank. The size and sha-pe have been adapted to the needs of patients with Parkinson's disease. Results and discussions. In order to obtain the devices, cheap materials were used at the disposal of every person eager to make them. It started with simple objects that any patient uses for personal hygiene and more. The technique of making the devices was a very simple one, from the very beginning the steps that must be followed in order to make them were clearly established. Conclusions. Using the devices made during the physiotherapy sessions, significant improvements of the life quality for patients with Parkinson's disease were observed.

Comparison of Mini-Mental State Examination and Montreal Cognitive Assessment Ratings Across Levels of Parkinson's Disease Severity

BACKGROUND

Cognitive impairment (CI) is common in Parkinson's disease (PD) and an important cause of disability. Screening facilitates early detection of CI and has implications for management. Preclinical disability is when patients have functional limitations but maintain independence through compensatory measures.

OBJECTIVE

The objective of this study was to investigate the relationship between scores on the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) with levels of PD severity and disability.

METHODS

PD patients (n = 2,234) in a large observational study were stratified by disease severity, based on Total Unified Parkinson's Disease Rating Scale (Total UPDRS) and Hoehn and Yahr (HY) stage. Using MMSE (n = 1,184) or MoCA (n = 1,050) and basic (ADL) and instrumental activities of daily living (IADL) scales for disability, linear regression analysis examined associations between cognitive status and disability.

RESULTS

Cognition and disability were highly correlated, with the strongest correlation between IADL and MoCA. Only 16.0% of mean MMSE scores were below threshold for CI (28) and only in advanced PD (Total UPDRS 60+, HY≥3). MoCA scores fell below CI threshold (26) in 66.2% of the sample and earlier in disease (Total UPDRS 30+, HY≥2), corresponding with impairments in ADLs.

CONCLUSION

In a large clinical dataset, a small fraction of MMSE scores fell below cutoff for CI, reinforcing that MMSE is an insensitive screening tool in PD. MoCA scores indicated CI earlier in disease and coincided with disability. This study shows that MoCA, but not MMSE is sensitive to the emergence of early cognitive impairment in PD and correlates with the concomitant onset of disability.

Quantifying activities of daily living impairment in Parkinson's disease using the Functional Activities Questionnaire

OBJECTIVE

Cognitive-driven activity of daily living (ADL) impairment in Parkinson's disease (PD) is increasingly discussed as prodromal marker for dementia. Diagnostic properties of assessments for this specific ADL impairment are sparsely investigated in PD. The ability of the Functional Activities Questionnaire (FAQ) for differentiating between PD patients with normal cognition and with mild cognitive impairment (PD-MCI), according to informant and self-reports, was examined. Global cognitive function in groups with and without mild ADL impairment was compared according to different cut-offs.

METHODS

Multicenter data of 589 patients of an international cohort (CENTRE-PD) were analyzed. Analyses were run separately for informant-rated and self-rated FAQ. Receiver operating characteristic (ROC) analysis was conducted to define the optimal FAQ cut-off for PD-MCI (≥ 1), and groups were additionally split according to reported FAQ cut-offs for PD-MCI in the literature (≥ 3, ≥ 5). Binary logistic regressions examined the effect of the Montreal Cognitive Assessment (MoCA) score in PD patients with and without mild ADL impairment.

RESULTS

Two hundred and twenty-five (38.2%) patients were classified as PD-MCI. For all three cut-off values, sensitivity was moderate to low (< 0.55), but specificity was moderately high (> 0.54) with a tendency of higher values for self-reported deficits. For the self-report, the cut-off ≥ 3 showed a significant effect of the MoCA (B =  - 0.31, p = 0.003), where FAQ ≥ 3 patients had worse cognition. No effect for group differences based on informant ratings was detected.

CONCLUSION

Our data argue that self-reported ADL impairments assessed by the FAQ show a relation to the severity of cognitive impairment in PD.

Occupational Therapy Interventions for Instrumental Activities of Daily Living for Adults With Parkinson's Disease: A Systematic Review

IMPORTANCE

Instrumental activities of daily living (IADLs) are important for independence, safety, and productivity, and people with Parkinson's disease (PD) can experience IADL limitations. Occupational therapy practitioners should address IADLs with their clients with PD.

OBJECTIVE

To systematically review the evidence for the effectiveness of occupational therapy interventions to improve or maintain IADL function in adults with PD.

DATA SOURCES

MEDLINE, CINAHL, PsycINFO, OTseeker, and Cochrane databases from January 2011 to December 2018. Study Selection and Data Collection: Primary inclusion criteria were peer-reviewed journal articles describing Level 1-3 studies that tested the effect of an intervention within the scope of occupational therapy on an IADL outcome in people with PD. Three reviewers assessed records for inclusion, quality, and validity following Cochrane Collaboration and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

FINDINGS

Twenty-two studies met the inclusion criteria and were categorized into four themes on the basis of primary focus or type of intervention: physical activity, specific IADL-focused, cognitive rehabilitation, and individualized occupational therapy interventions. There were 9 Level 1b, 9 Level 2b, and 4 Level 3b studies. Strong strength of evidence was found for the beneficial effect of occupational therapy-related interventions for physical activity levels and handwriting, moderate strength of evidence for IADL participation and medication adherence, and low strength of evidence for cognitive rehabilitation.

CONCLUSIONS AND RELEVANCE

Occupational therapy interventions can improve health management and maintenance (i.e., physical activity levels, medication management), handwriting, and IADL participation for people with PD. Further research is needed on cognitive rehabilitation. This review is limited by the small number of studies that specifically addressed IADL function in treatment and as an outcome. What This Article Adds: Occupational therapy intervention can be effective in improving or maintaining IADL performance and participation in people with PD. Occupational therapy practitioners can address IADL function through physical activity interventions, interventions targeting handwriting and medication adherence, and individualized occupational therapy interventions.
