Understanding patients’ and caregivers’ perspectives and educational needs in Parkinson’s disease: a multi-ethnic Asian study

Ethnoracial differences for caregiving burden in Parkinson's disease

INTRODUCTION

Caregivers play an important role in Parkinson's disease (PD) treatment, especially as the disease progresses. As the symptom profile and needs of people with PD (PwP) differ across ethnoracial groups, whether caregiving needs also differ for different ethnoracial groups should be investigated.

METHODS

Data were obtained from the Parkinson's Foundation funded Parkinson's Outcomes Project for PwP identifying as Hispanic (n = 495), non-Hispanic Asian (n = 170), non-Hispanic Black (n = 162), or non-Hispanic White (n = 7687). Cross-sectional and longitudinal total Multidimensional Caregiver Strain Index (MCSI) and domain-specific scores for caregiving burden were compared across the ethnoracial groups. Effect of demographics and clinical variables, interaction of these variables with ethnoracial groups for caregiver burden was assessed.

RESULTS

Care partners of PwP identifying as non-Hispanic Asian experienced the most burden. PwP identifying as non-Hispanic White were oldest, yet their care partners experienced the least burden. Care partners of PwP identifying as non-Hispanic Asian experienced more burden in physical and social domains, care partners of PwP identifying as Hispanic experienced more burden in financial and elder demanding/manipulative domains. Over time, burden increased similarly across the ethnoracial groups. Effect of frequency of falls, hospital admission, neuropsychiatric disorder and social support on burden over time differed across the groups.

CONCLUSION

PwP from different ethnoracial groups can experience different levels of caregiving burden. Predictors for caregiving burden, such as social support and falls can have different impacts based on ethnicity and race. Caregiver needs should also be assessed and culturally competent support should be provided to benefit all affected by PD.

A Review on Natural Antioxidants for Their Role in the Treatment of Parkinson's Disease

The neurodegenerative condition known as Parkinson's disease (PD) is brought on by the depletion of dopaminergic neurons in the basal ganglia, which is the brain region that controls body movement. PD occurs due to many factors, from which one of the acknowledged effects of oxidative stress is pathogenic pathways that play a role in the development of Parkinson's disease. Antioxidants, including flavonoids, vitamins E and C, and polyphenolic substances, help to reduce the oxidative stress brought on by free radicals. Consequently, this lowers the risk of neurodegenerative disorders in the long term. Although there is currently no cure for neurodegenerative illnesses, these conditions can be controlled. The treatment of this disease lessens its symptoms, which helps to preserve the patient's quality of life. Therefore, the use of naturally occurring antioxidants, such as polyphenols, which may be obtained through food or nutritional supplements and have a variety of positive effects, has emerged as an appealing alternative management strategy. This article will examine the extent of knowledge about antioxidants in the treatment of neurodegenerative illnesses, as well as future directions for research. Additionally, an evaluation of the value of antioxidants as neuroprotective agents will be provided.

Management of dysphagia and gastroparesis in Parkinson’s disease in real-world clinical practice – Balancing pharmacological and non-pharmacological approaches

Gastrointestinal (GI) issues are commonly experienced by patients with Parkinson’s disease (PD). Those that affect the lower GI tract, such as constipation, are the most frequently reported GI problems among patients with PD. Upper GI issues, such as swallowing dysfunction (dysphagia) and delayed gastric emptying (gastroparesis), are also common in PD but are less well recognized by both patients and clinicians and, therefore, often overlooked. These GI issues may also be perceived by the healthcare team as less of a priority than management of PD motor symptoms. However, if left untreated, both dysphagia and gastroparesis can have a significant impact on the quality of life of patients with PD and on the effectiveness on oral PD medications, with negative consequences for motor control. Holistic management of PD should therefore include timely and effective management of upper GI issues by utilizing both non-pharmacological and pharmacological approaches. This dual approach is key as many pharmacological strategies have limited efficacy in this setting, so non-pharmacological approaches are often the best option. Although a multidisciplinary approach to the management of GI issues in PD is ideal, resource constraints may mean this is not always feasible. In ‘real-world’ practice, neurologists and PD care teams often need to make initial assessments and treatment or referral recommendations for their patients with PD who are experiencing these problems. To provide guidance in these cases, this article reviews the published evidence for diagnostic and therapeutic management of dysphagia and gastroparesis, including recommendations for timely and appropriate referral to GI specialists when needed and guidance on the development of an effective management plan.

The subjective experience of family caregivers of people living with Parkinson's disease: a meta-ethnography of qualitative literature

BACKGROUND AND AIMS

Parkinson's disease patients (PwPD) rely heavily on their family caregivers. However, there remains uncertainty regarding the subjective experience of the family caregivers of PwPD. This study aims to provide an in-depth summary of the current knowledge about the subjective experiences of family caregivers caring for PwPD, to understand the factors that influence this experience and to provide the evidence for healthcare services.

METHODS

We conducted a systematic review and meta-ethnography using Noblit and Hare's approach. The search strategy used MeSH terms in combination with free-text searching of 10 databases (from their inception until July 2021). Titles and abstracts were reviewed by two reviewers and, for the studies that met the eligibility criteria, full-text articles were obtained. The Critical Appraisal Skills Program (CASP) checklist was employed to assess the quality of studies.

RESULTS

A total of 3318 studies were screened and 29 qualitative studies were included in this review. These studies recorded the experience of 399 participants across 12 countries, most were females. Five themes emerged: (a) feelings related to PD; (b) challenges to family life; (c) external challenges; (d) adjustment and adaptation; (e) external support. We propose a new conceptual model that highlights that the experiences of caregivers for PwPD are dynamic and influenced by a variety of internal and external factors.

CONCLUSION

Our findings illustrate the complex and dynamic experiences of family caregivers for PwPD. It is necessary to explore how the influencing factors can be modified to improve the lived experience of family caregivers.

Exploring Unmet Information Needs of People with Parkinson's Disease and Their Families: Focusing on Information Sharing in an Online Patient Community

This study aimed to examine the unmet information needs of people with Parkinson’s disease and their family members by analyzing Parkinson’s disease-related posts in online communities. Data were collected from one of the largest online people with Parkinson’s disease communities used in South Korea. The word cloud, the main questions from the free-posting messages, as well as the frequently asked symptoms and side effects of the medication, were analyzed using content analysis. The commonly mentioned main questions from the free-posting messages have pertained to treatment-related information, such as effects and side effects of medication, deep brain stimulation, and complementary and alternative medicine. People with Parkinson’s disease and their families depend not only on health care providers but also on using online communities to find the information that they need. However, there is a need for treatment-specific information, such as anti-Parkinson drugs, deep brain stimulation, and complementary alternative therapies. As for the method of providing information for people with Parkinson’s disease and their families, it will be effective to provide tailored education services using online communities and social media by using their information needs and preferred resources.

Exploring the perceptions and stigmatizing experiences of Israeli family caregivers of people with Parkinson's disease

Providing care to people with Parkinson's disease (PD) poses challenges for family carers, including experiencing stigmatic beliefs -i.e., family stigma. However, to the best of our knowledge, there is no empirical study examining the stigmatic experiences of family members of people with PD. This was the aim of the present study. Three focus groups with 22 Israeli spouses of people with PD were conducted. Data were analyzed using theory-led thematic analysis. Overall, the spouses in our study shared mainly experiences of the stigma attached to the illness and/or to their loved ones, and not to themselves as carers. Three major themes emerged: the stereotypes that typify PD, stigmatizing behaviors towards the person with the disease, and structural stigma. Our findings highlight the profound stigma confronting carers of persons with PD, particularly when it comes to structural stigma.

Shear wave elastography characteristics of upper limb muscle in rigidity-dominant Parkinson's disease

BACKGROUND

Rigidity is one of the major manifestations of Parkinson's disease (PD), but no quantitative and objective imaging method has been developed to measure rigidity. Ultrasound shear wave elastography (SWE) can reflect the stiffness of tissue by providing a quantitative index. Thus, we conducted this study to evaluate the potential clinical value of SWE in assessing rigidity in PD.

METHODS

A total of 63 subjects (44 patients with rigidity-dominant PD and 19 right-dominant-hand normal controls with matched age) were enrolled, and each underwent ultrasound SWE testing. The tests were conducted on the brachioradialis (BR) and biceps brachii (BB) on the more affected side in patients with PD and on the right side in normal controls. Differences in quantitative shear wave velocity (SWV) between patients with PD and normal controls were determined. The relationship of muscle SWV with joint rigidity, UPDRSIII, disease duration, sex, and age in patients with PD was analyzed. The intraclass correlation coefficient (ICC) was used to evaluate the reliability of SWE in assessing muscle stiffness in patients with PD.

RESULTS

The mean SWVs of the BB and BR were higher in the PD group (3.65±0.46 and 4.62±0.89 m/s, respectively) than in normal controls (2.79±0.37 and 3.26±0.40 m/s, respectively). Stiffness in BR and BB was correlated with the upper-limb joint rigidity, UPDRSIII, and disease duration but not with sex or age in the PD group. The intraobserver correlation coefficients (ICCs) for interobserver and intraobserver variations in measuring SWV were 0.85 (95% confidence interval 0.56-0.95) and 0.85 (95% confidence interval 0.58-0.95), respectively, for BR and 0.90 (95% confidence interval 0.73-0.97) and 0.86 (95% confidence interval 0.61-0.95), respectively, for BB.

CONCLUSIONS

SWV is associated with joint rigidity and disease duration, indicating that SWE can be potentially used as an objective and quantitative tool for evaluating rigidity.

Establishing apomorphine treatment in Thailand: understanding the challenges and opportunities of Parkinson's disease management in developing countries

INTRODUCTION

The increasing global burden of Parkinson's disease (PD) poses a particular challenge for developing countries, such as Thailand, when delivering care to a geographically diverse populace with limited resources, often compounded by a lack of expertise in the use of certain PD medications, such as device-aided therapies (DAT).

AREAS COVERED

A panel of local, regional, and international PD experts convened to review the unmet needs of PD in Thailand and share insights into effective delivery of DAT, focusing on experience with apomorphine infusion. Despite its proven efficacy and safety, implementation of apomorphine infusion as a new option was not straightforward. This has prompted a range of health-care professional and patient-focused initiatives, led by the Chulalongkorn Center of Excellence for Parkinson's Disease and Related Disorders in Bangkok, to help establish a more coordinated approach to PD management throughout the country and ensure patients have access to suitable treatments.

EXPERT OPINION

Overcoming the challenges of education, proficiency, resource capacity and standard of care for PD patients in developing countries requires a coordinated effort both nationally and beyond. The best practices identified in Thailand following the introduction of apomorphine infusion might be helpful for other countries when implementing similar programs.
