Reaching Those Most in Need - A Call to Action for Advanced Parkinson's Disease

Anti-Inflammatory Effect of Traditional Chinese Medicine on the Concept of Mind-Body Interface

In this chapter, we conducted a systemic literature review for the anti-inflammatory effects of Traditional Chinese Medicine (TCM) applying molecular mechanisms focusing on the neuroinflammation and gut-brain axis in three neuropsychiatric disorders: major depressive disorder, Alzheimer's disease, and Parkinson's disease. We demonstrated the anti-inflammation or immunomodulation effects of TCM, including acupuncture, from basic and clinical research, including cellular and molecular approaches. In conclusion, inflammation plays a critical role in the neuropsychopathological process. At the same time, anti-inflammation seems to be the common biological pathway for the effects of TCM and acupuncture in depression, Alzheimer's disease, and Parkinson's disease.

Clinical Phenotype of LRRK2 R1441C in 2 Chinese Sisters

Pathogenic and risk variants in the LRRK2 gene are among the main genetic contributors to Parkinson's disease (PD) worldwide, and LRRK2-targeted therapies for patients with PARK-LRRK2are now entering clinical trials. However, in contrast to the LRRK2 G2019S mutation commonly found in Caucasians, North-African Arabs, and Ashkenazi Jews, relatively little is known about other causative LRRK2 mutations, and data on genotype-phenotype correlations are largely lacking. This report is from an ongoing multicentre study in which next-generation sequencing-based PD gene panel testing has so far been conducted on 499 PD patients of various ethnicities from Malaysia. We describe 2 sisters of Chinese ancestry with PD who carry the R1441C mutation in LRRK2 (which in Asians has been reported in only 2 Chinese patients previously), and highlight interesting clinical observations made over a decade of close follow-up. We further explored the feasibility of using a brief, expert-administered rating scale (the Clinical Impression of Severity Index; CISI-PD) to capture data on global disease severity in a large (n = 820) unselected cohort of PD patients, including severely disabled individuals typically excluded from research studies. All patients in this study were managed and evaluated by the same PD neurologist, and these data were used to make broad comparisons between the monogenic PD cases versus the overall "real world" PD cohort. This report contributes to the scarce literature on R1441C PARK-LRRK2, offering insights into natural history and epidemiological aspects, and provides support for the application of a simple and reliable clinical tool that can improve the inclusion of under-represented patient groups in PD research.

Dyadic Decision-Making in Advanced Parkinson’s Disease: A Mixed Methods Study

People with advanced Parkinson’s disease (PD) are living at home being cared for by a family member. Decisions about health care and living preferences are made in a family context. The aims of the study were to (a) examine the types and timing of the decisions being made by dyads (person with Parkinson’s [PWP] and caregiver) in advanced PD; and (b) explore perceived decision quality relative to specific decisions made. A mixed methods design of semi-structured dyad interviews followed by individual completion of decision measures twice at six months apart was utilized. Decisions involved obtaining more services in the home, moving into assisted living communities, maintaining as is, and initiating hospice. There was high decision quality as reflected by low decisional conflict and regret without statistical differences within the dyad. The findings provide insight into the nature of decisions dyads face and suggest ways that health care providers can support decision-making.

Severely Affected by Parkinson Disease: The Patient's View and Implications for Palliative Care

INTRODUCTION

People severely affected by Parkinson disease (PD)/atypical parkinsonism (AP) comprise a heterogeneous group with distinct needs, which so far remain largely unexamined. The aim of our study was to analyze reasons for feeling severely affected and document unmet needs in a patient subgroup severely affected by PD/AP using solely a subjective inclusion criterion.

METHODS

Patients feeling severely affected by PD/AP were recruited via a magazine published by the German Parkinson Association. A questionnaire was sent out nationwide. Besides analyzing the closed-ended questions, a subsample of 40% was analyzed regarding the open-ended questions using content analysis. Correlations between subjectively felt severe affectedness and objective criteria were calculated.

RESULTS

Eight hundred fourteen questionnaires were analyzed. Sample characteristics were: mean age 70 years; 60.3% male; time since diagnosis up to 37 years; and Hoehn and Yahr score (if known) 3 (44.6%), followed by 4 (23.9%). Significant associations were observed between subjectively felt severe affectedness and Hoehn and Yahr ( P ≤ .05), poorer health ( P ≤ .01), higher nursing care level ( P ≤ 0.01), and having no children ( P ≤ .05). Most common reasons for feeling severely affected were mobility impairment (34.9%), coordination problems (17.0%), speech problems (12.2%), and limited day-to-day activities (7.8%). Most often expressed unmet needs were support in everyday life (28.1%), medical treatment (15.2%), help with financial services (11.6%), and social integration (9.9%).

CONCLUSIONS

To meet the complex needs, an integrated multidisciplinary and multiprofessional approach is indicated befitting palliative care principles. Herein, home-based services seem of special importance for patients in advanced disease stages.
