Abstract
BACKGROUND Parkinson's disease (PD) drastically affects motor and cognitive function, but evidence shows that motor-cognitive training improves disease symptoms. Motor-cognitive training in the home is scarcely investigated and eHealth methods can provide continual support for PD self-management. Feasibility testing is however required. OBJECTIVE To assess the feasibility (i) Recruitment capability (ii) Acceptability and Suitability (iii) Demand and Safety of a home-based motor-cognitive eHealth exercise intervention in PD. METHODS The 10-week intervention was delivered using the ExorLive® application and exercises were individually adapted and systematically progressed and targeted functional strength, cardiovascular fitness, flexibility, and motor-cognitive function. People with mild-to moderate PD were assessed before and after the intervention regarding; gait performance in single and dual-task conditions; functional mobility; dual-task performance; balance performance; physical activity level; health related quality of life and perceived balance confidence and walking ability; global cognition and executive function. Feasibility outcomes were continuously measured using a home-exercise diary and contact with a physiotherapist. Changes from pre- and post-intervention are reported descriptively. RESULTS Fifteen participants (mean age 68.5 years) commenced and 14 completed the 10-week intervention. In relation to intervention Acceptability, 64% of the motor sessions and 52% of motor-cognitive sessions were rated as "enjoyable". Concerning Suitability, the average level of exertion (Borg RPE scale) was light (11-12). Adherence was high, with 86% of all (420) sessions reported as completed. No falls or other adverse events occurred in conjunction with the intervention. CONCLUSIONS This motor-cognitive eHealth home exercise intervention for PD was safe and feasible in terms of Recruitment capability, Acceptability, Safety and Demand. The intensity of physical challenge needs to be increased before testing in an efficacy trial. TRIAL REGISTRATION This trial is registered at Clinicaltrials.gov (NCT05027620).

Front Neurosci 2023; 17:1278817.

Abstract
Introduction Cognitive decline is common in Parkinson's disease (PD). Calculating personalized risk of cognitive decline in PD would allow for appropriate counseling, early intervention with available treatments, and inclusion in disease-modifying trials. Methods Data were from the Parkinson's Progression Markers Initiative de novo cohort. Baseline scores were calculated for Lifestyle for Brain Health (LIBRA) and the Montreal Parkinson Risk of Dementia Scale (MoPaRDS) per prior literature and preliminary Parkinson's disease Risk Estimator for Decline In Cognition Tool (pPREDICT) by attributing a point for fourteen posited risk factors. Baseline and 5-year follow-up composite cognitive scores (CCSs) were calculated from a neuropsychological battery and used to define cognitive decliners (PD-decline) versus maintainers (PD-maintain). Results The PD-decline group (n = 44) had higher LIBRA (6.76 ± 0.57, p < 0.05), MoPaRDS (2.45 ± 1.41, p < 0.05) and pPREDICT (4.52 ± 1.66, p < 0.05) scores compared to the PD-maintain group (n = 263; LIBRA 4.98 ± 0.20, MoPaRDS 1.68 ± 1.16, pPREDICT 3.38 ± 1.69). Area-under-the-curve (AUC) for LIBRA was 0.64 (95% confidence interval [CI], 0.55-0.73), MoPaRDS was 0.66 (95% CI, 0.58-0.75) and for pPREDICT was 0.68 (95% CI, 0.61-0.76). In linear regression analyses, LIBRA (p < 0.05), MoPaRDS (p < 0.05) and pPREDICT (p < 0.05) predicted change in CCS. Only age stratified by sex (p < 0.05) contributed significantly to the model for LIBRA. Age and presence of hallucinations (p < 0.05) contributed significantly to the model for MoPaRDS. Male sex, older age, excessive daytime sleepiness, and moderate-severe motor symptoms (all p < 0.05) contributed significantly to the model for pPREDICT. Conclusion Although MoPaRDS is a PD-specific tool for predicting cognitive decline relying on only clinical features, it does not focus on potentially modifiable risk factors. LIBRA does focus on potentially modifiable risk factors and is associated with prediction of all-cause dementia in some populations, but pPREDICT potentially demonstrates improved performance in cognitive decline risk calculation in individuals with PD and may identify actionable risk factors. As pPREDICT incorporates multiple potentially modifiable risk factors that can be obtained easily in the clinical setting, it is a first step in developing an easily assessable tool for a personalized approach to reduce dementia risk in people with PD.

Abstract
BACKGROUND AND PURPOSE Parkinson's disease (PD) is the most common neurodegenerative movement disorder. Symptom severity leads to devastating consequences such as falls, immobility, impaired quality of life, and reduced general activity. Adopting a sedentary lifestyle creates a vicious circle, as physical inactivity can negatively affect the clinical domains of PD. Despite the recognition of the disease-modifying potential of physical activity (PA), achieving adequate exercise levels can be challenging for individuals with PD. This study aimed to investigate the repercussions of exercise-based interventions to improve PA levels in persons with PD through a systematic review with meta-analysis. METHODS A search was conducted from database inception to February 2021 across 3 databases: PubMed, Web of Science, and Scopus. Randomized controlled trials were included if they involved persons with PD, outcome measures associated with PA levels, and an exercise-based intervention. Two reviewers performed independent data extraction and methodologic quality assessment of the studies using the Downs and Black quality checklist. RESULTS A total of 6 studies were included in the study (1251 persons with PD). Four intervention types were identified: balance, strength, aerobic, and multimodal exercise (combination of several types of exercise programs). The meta-analysis showed that exercise interventions have a positive effect on PA (standard mean difference = 0.50, 95% CI =-0.02, 1.00; P = .06). The risk of bias was generally low. CONCLUSIONS The findings support the use of exercise-based interventions (aerobic exercise, balance exercise, strength exercise, and/or multimodal exercise) to improve PA levels. However, the limited number of studies and the heterogeneity of the interventions do not allow us to draw a definitive conclusion.

Abstract
BACKGROUND Fear of falling avoidance behavior (FFAB) is common in Parkinson's disease (PD). OBJECTIVES The objectives of the study are to determine what activities are most avoided due to FFAB among people with PD and whether any associations exist with demographic factors or fall history. METHOD Cross-sectional analysis of 174 individuals with PD using the Modified FFAB Questionnaire. RESULTS Walking in dimly lit, unfamiliar places, and different surfaces, lifting and carrying objects, walking in crowded places, recreational/leisure activities, and going up/downstairs were most avoided. Fallers reported more FFAB (ps < .029). FFAB for certain activities was associated with increased or decreased odds of falling. CONCLUSION Individuals with PD avoid walking in compromised situations and engaging in recreational/leisure activities due to FFAB. While excessive FFAB may increase the odds of falling, protective forms may be associated with decreased odds. Targeting FFAB among individuals with PD may increase safe participation in meaningful occupations in the home and community.

Abstract
Gait and balance problems commonly occur in Parkinson's disease (PD). However, balance tasks with only one performance objective (e.g., sit-to-stand) may not be sufficient, compared to dual motor tasks (e.g., carrying a tray while walking), to be applied to the assessments and interventions which are designed to promote PD patients' balance functioning, physical activity (PA) and health-related quality of life (HQoL). The aim of this study, therefore, was to determine whether advanced dynamic balance, measured by a demanding motor-motor dual task, is a significant predictor of PA/HQoL in older adults with and without PD. Participants with (n = 22) and without (n = 23) PD were assessed using the Berg Balance Scale (BBS), the single leg hop and stick series task (SLHS), the Physical Activity Scale for the Elderly (PASE), and the Parkinson's Disease Questionnaire-39 (PDQ39). We calculated the R2 change, namely the incremental validity, between the multiple regression models before and after adding the scores on the BBS/SLHS. While controlling for biological and socioeconomic covariates, competence in the SLHS task provided moderate and large levels of incremental validity to PA (ΔR2 = 0.08, Cohen's f2 = 0.25, p = .035) and HQoL (ΔR2 = 0.13, Cohen's f2 = 0.65, p < .001), respectively. In particular for participants with PD, the SLHS explained significantly more variance in HQoL in relation to psychosocial functioning (ΔR2 = 0.25, Cohen's f2 = 0.42, p = .028) compared to the BBS (p = .296). Assessing advanced dynamic balance by means of a highly demanding dual-task paradigm was not only strongly associated with PA but also covered a wider spectrum of HQoL components. This approach is recommended for use in evaluations and interventions carried out in clinical and research settings in order to promote healthy living.

Abstract
OBJECTIVE This study aimed to investigate whether the physical activity scale for the elderly (PASE) is a valid tool in measuring physical activity (PA) in people with motor neuron disease (MND) and to identify the demographic and clinical factors that predict PA participation in this population. DESIGN A prospective, observational study involving 100 ambulant participants with MND. SETTING This study was conducted at a multidisciplinary specialist MND clinic. The clinic is fully funded by the local public health system and patients receiving care here are not expected to pay for their consultation. PARTICIPANTS 190 patients with MND who had a physiotherapy appointment at the specialist clinic between July and October 2018 were screened. Of these, 100 participants (mean age 67 years [SD=12], 64% [n=64] men) who were ambulant (with or without assistance) were recruited (N=100). INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES PASE questionnaire, amyotrophic lateral sclerosis functional rating scale-Revised (ALSFRS-r), forced vital capacity (FVC). RESULTS The results showed that engagement in PA is generally low, with median PASE score of 57. The PASE had fair-moderate correlation with ALSFRS-R total scores (rho=0.607; P<.000) and FVC (rho=0.250; P=.030). Standard multiple regression analyses showed that disease severity (ALSFRS-R total score) was the strongest predictor of PA levels (β= 0.54; 95% confidence interval 0.02,0.06). The most frequently selected physical activities of choice for people with MND were activities around their homes and the biggest barrier to participation is fatigue. CONCLUSION Present findings suggest that the PASE can be used to measure PA participation in people with MND. Details about activity of choice and barriers to participation present important considerations in designing exercise programs in this population to maximize compliance and therefore effectiveness.

Abstract
Since Parkinson's disease (PD) is a heterogeneous disorder with symptoms, such as tremors, gait and speech disturbances, or memory loss, individualized diagnostics are needed to optimize treatment. In their current form, the typical paper-pencil methods traditionally used to track disease progression are too coarse to capture the subtleties of clinical phenomena. For this reason, digital biomarkers that capture, for example, motor function, cognition, and behavior using apps, wearables, and tracking systems are becoming increasingly established. However, given the high prevalence of cognitive impairment in PD, digital cognitive biomarkers to predict mental progression are important in clinical practice. This pilot study aimed to identify those components of our digital version of the TMT (dTMT) that allow discrimination between PD patients with and without cognitive deficits. A total of 30 healthy control (age 66.3 ± 8.61) and 30 participants with PD (age 68.3 ± 9.66) performed the dTMT using a touch-sensitive tablet to capture enhanced performance metrics, such as the speed between and inside circles. The decomposition of cognitive abilities based on integrating additional variables in the dTMT revealed that the Parkinson's disease group was significantly more sensitive to parameters of inhibitory control. In contrast, the mild cognitive impairment group was sensitive to parameters of cognitive flexibility and working memory. The dTMT allows objective, ecologically valid, and long-term cognitive and fine-motor performance tracking, suggesting its potential as a digital biomarker in neurodegenerative disorders.

Abstract
BACKGROUND AND PURPOSE Physical activity (PA) has many known benefits for people with Parkinson disease (PD); however, many people do not meet recommended levels of frequency or intensity. We designed Engage-PD, a PA coaching program delivered via telehealth and grounded in self-determination theory to promote PA uptake and facilitate exercise self-efficacy in people with Parkinson disease. This study aimed to determine the feasibility and preliminary efficacy of Engage-PD, and to explore whether baseline characteristics were associated with outcomes. METHODS A single cohort of people with PD (n = 62, Hoehn and Yahr I-III) participated in the 3-month Engage-PD program, which consisted of up to 5 telehealth coaching sessions delivered by physical therapists. Feasibility was evaluated based on recruitment and retention rates, along with participants' feedback. Planned and unplanned PA, exercise self-efficacy (ESE), and individualized goals were assessed pre- and post-intervention. Relationships between baseline characteristics and changes in planned PA and ESE were also evaluated. RESULTS Recruitment (62%) and retention (85%) rates were high, and the intervention was well accepted and perceived by the participants. From pre- to postintervention, participants increased planned PA (d = 0.33), ESE (d = 1.20), and individualized goal performance (d = 1.63) and satisfaction (d = 1.70). Participants with lower baseline planned PA experienced greater improvements in planned PA, and those with lower baseline ESE experienced greater improvements in ESE. DISCUSSION AND CONCLUSIONS A telehealth PA coaching program for people with PD was feasible and potentially efficacious. Physical therapist-led coaching may be an important component of a consultative model of care starting early in the disease process.Video Abstract available for more insights from the authors (see the Video, Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A393).

Abstract
Background The clinical, neuropsychological, and socioeconomic factors affecting Parkinson's disease (PD) during COVID‐19 pandemic across different populations have not been systematically studied. To address this, we conducted a meta‐analysis of factors that impact the well‐being of PD patients during the pandemic. Methods Medline and Embase were searched for articles published between 2020 and 2022. We conducted random‐effects pooling of estimates and meta‐regression. Results Twenty‐seven studies involving 13,878 patients from America, Europe, Asia, and Africa were included. There is a high prevalence of decreased physical activity and exercise, and worsening motor and neuropsychiatric symptoms (17–56%). Patients in lower‐income countries more frequently reported worsening anxiety (adjusted OR [aOR] 8.94, 95% confidence interval [CI] 1.62–49.28, p = 0.012), sleep (aOR 5.16, 95% CI 1.15–23.17, p = 0.032), and PD symptoms (aOR 3.57, 95% CI 0.96–13.34, p = 0.058). Lockdown was associated with decreased exercise levels (aOR 0.13, 95% CI 0.02–0.78, p = 0.025) and worsening mood (aOR 0.48, 95% CI 0.24–0.95, p = 0.035). Younger age correlated with decreased physical activity (β −0.30, 95% CI −0.53 to −0.07, p = 0.012), exercise (β −0.11, 95% CI −0.15 to −0.07, p < 0.001), worsening PD symptoms (β −0.08, 95% CI −0.15 to −0.01, p = 0.018), and sleep (β −0.14, 95% CI −0.27 to 0, p = 0.044). Female PD patients reported a greater decrease in physical activity (β 11.94, 95% CI 2.17–21.71, p = 0.017) and worse sleep (β 10.76, 95% CI 2.81–18.70, p = 0.008). Conclusion This large meta‐analysis of PD patients in diverse populations identified a high prevalence of physical and mental worsening during the COVID‐19 pandemic, with patients in lower‐income countries being exceptionally vulnerable.

Abstract
BACKGROUND Due to the clinical impact of exercise in patients with Parkinson's disease (PD), management should include personalized and effective exercises according to patient's PD stage. We investigated the detailed exercise behaviors of patients with mild to advanced PD and compared their patterns between PD with and without postural instability (PI). METHODS We enrolled PD patients from September to December 2019. Clinical data on parkinsonism, exercise behaviors, and Physical Activity Scale of the Elderly (PASE) scores were collected and compared between mild PD without PI (Hoehn-Yahr (HY) stages 1 and 2) and advanced PD with PI (HY stages 3 and 4). RESULTS In total, 263 PD patients were recruited. The mean exercise frequency was 4.7 ± 2.1 times/week, and the average duration was 7.8 ± 6.7 hours/week. The most common exercise was an aerobic exercise (71.9%) of mild-to-moderate intensity, with active walking being the most common (49.0%). The mild PD patients demonstrated a higher duration and intensity of exercise and more physical activity than the advanced PD patients. However, the frequency of exercise was not significantly different between the two groups. The PASE score was significantly higher in mild PD patients than in advanced PD patients (p < 0.001). CONCLUSION PD patients focused mostly on aerobic exercises, especially active walking. With the disease progression, the amount and intensity of exercise decreased while frequency remained. Higher intensity of exercise is needed in the mild PD group, while the advanced PD group requires the increment of duration for each exercise session.

[PMID: 35426538 PMCID: PMC9011371 DOI: 10.1007/s00702-022-02501-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2022] [Accepted: 04/06/2022] [Indexed: 11/27/2022]
Abstract
Parkinson’s disease (PD) is the fastest growing neurodegenerative disease, but disease-modifying or preventive treatments are lacking. Physical activity is a modifiable factor that decreases the PD risk and improves motor symptoms in PD. Understanding which dimensions of gait performance correlate with physical activity in PD can have important pathophysiological and therapeutic implications. Clinical/demographic data together with physical activity levels were collected from thirty-nine PD patients. Gait analysis was performed wearing seven inertial measurement units on the lower body, reconstructing the subjects’ lower body motion using 3D kinematic biomechanical models. Higher physical activity scores were significantly correlated with MDS-UPDRS part III scores (r = − 0.58, p value = 9.2 × 10−5), age (r = − 0.39, p value = 1.5 × 10−2) and quality-of-life (r = − 0.47, p value = 5.9 × 10−3). Physical activity was negatively associated with MDS-UPDRS part III scores after adjusting for age and disease duration (β = − 0.08530, p value = 0.0010). The effect of physical activity on quality-of-life was mediated by the MDS-UPDRS part III (62.10%, 95% CI = 0.0758–1.78, p value = 0.022). The level of physical activity was correlated primarily with spatiotemporal performance. While spatiotemporal performance displays the strongest association with physical activity, other quality-of-movement dimensions of clinical relevance (e.g., smoothness, rhythmicity) fail to do so. Interventions targeting these ought to be leveraged for performance enhancement in PD through neuroprotective and brain network connectivity strengthening. It remains to be ascertained to which extent these are amenable to modulation.

Abstract
BACKGROUND Physical activity (PA) level is decreased in individuals with Parkinson´s disease (PD). To increase the PA level improves both motor and non-motor symptoms of this population. It is known that gait performance and five times sit-to-stand (FTSTS) are associated with PA level; therefore, it is of great relevance for rehabilitation purposes to understand whether these variables may predict PA level of individuals with PD. OBJECTIVE To investigate whether gait performance and FTSTS are predictors of PA level. METHODS Cross-sectional study with individuals with idiopathic PD modified Hoehn and Yahr staging scale between 1.0 and 3.0. The gait performance was measured by Functional Gait Assessment (FGA) and PA level was measured by an accelerometer for one week, during day and night through their time spend in locomotion (locomotion time-LT). Multiple linear regression was conducted with gait performance and FTSTS as independent variables and PA level (LT) as dependent variable. RESULTS Twenty-two participants were included, mean age 64.82 (8.39) and the mean storage of accelerometer time was 9.866 min (0.33). Both gait performance and FTSTS have moderate significant correlation with PA level (r = - 0.538 p < 0.01 and r = 0.625 p < 0.001, respectively). The linear regression model with FGA and FTSTS was significant (p < 0.05) and predicted 41% of LT. CONCLUSION Gait performance and FTSTS have important interaction with PA level measured by LT in individuals with PD, and it provides insights on the importance of these variables in predicting the PA level of its population.

Abstract
Importance The protective effects of physical activity (PA) against Parkinson disease (PD) development have been suggested; however, the association of PA with mortality in PD has rarely been investigated. Objective To evaluate the association between PA and mortality in individuals with PD and determine how the amount and maintenance of PA are associated with mortality. Design, Setting, and Participants This nationwide population-based cohort study used Korean National Health Insurance System data. Participants were included from January 1, 2010, and December 31, 2013, and were followed up until December 31, 2017. Data were analyzed from September 2020 to March 2021. Individuals who were newly diagnosed with PD were selected using the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision code G20 and registration code V124 in the program for rare intractable diseases in 2010 through 2013. Individuals who underwent health checkups within 2 years before and after the PD diagnosis were enrolled. Those aged younger than 40 years or with missing data were excluded. Exposures Physical activity levels were collected using self-reported questionnaires. Main Outcomes and Measures All-cause mortality. Results A total of 45 923 individuals were identified; 10 987 were enrolled, and 34 individuals younger than 40 years and 254 with missing data were excluded. A total of 10 699 individuals with PD were included; 4925 (46%) were male and 5774 (54%) were female, and the mean (SD) age was 69.2 (8.8) years. During the 8-year follow-up period, there were 1823 deaths (17%). The mortality rate was lower among individuals who were physically active vs inactive at all PA intensities (vigorous: hazard ratio [HR], 0.80 [95% CI, 0.69-0.93]; moderate: HR, 0.66 [95% CI, 0.55-0.78]; light: HR, 0.81 [95% CI, 0.73-0.90]). There was a significant inverse dose-response association between the total amount of PA and mortality (HRs: vigorous, 0.80 [95% CI, 0.69-0.93]; moderate, 0.66 [95% CI, 0.55-0.78]; light, 0.81 [95% CI, 0.73-0.90]; P < .001). Moreover, maintenance of PA was associated with the mortality rate. Individuals with PD who were physically active both before and after the PD diagnosis had the greatest reduction in mortality rate across all PA intensities (HRs: vigorous, 0.66 [95% CI, 0.50-0.88]; moderate, 0.49 [95% CI, 0.32-0.75]; light, 0.76 [95% CI, 0.66-0.89]). Individuals who started PA after receiving the PD diagnosis had a lower mortality rate than those who remained physically inactive (HRs: vigorous, 0.82 [95% CI, 0.70-0.97]; moderate, 0.69 [95% CI, 0.57-0.83]; light, 0.86 [95% CI, 0.78-0.98]). Conclusions and Relevance This analysis found a dose-response association between PA and all-cause mortality in PD. Reverse causality may exist, and future prospective randomized clinical trials are warranted to determine the effect of PA on mortality in PD.

Abstract
BACKGROUND People with Parkinson's disease are less physically active than controls. It is important to promote physical activity, which can be assessed using different methods. Subjective measures include physical activity questionnaires, which are easy and cheap to administer in clinical practice. Knowledge of the psychometric properties of physical activity questionnaires for people with Parkinson's disease is limited. The aim of this study was to evaluate the test-retest reliability of physical activity questionnaires in individuals with Parkinson's disease without cognitive impairment. METHODS Forty-nine individuals with Parkinson's disease without cognitive impairment participated in a test-retest reliability study. At two outpatient visits 8 days apart, the participants completed comprehensive questionnaires and single-item questions: International Physical Activity Questionnaire-Short Form (IPAQ-SF), Physical Activity Scale for the Elderly (PASE), Saltin-Grimby Physical Activity Level Scale (SGPALS) and Health on Equal Terms (HOET). Test-retest reliability was evaluated using the intraclass correlation coefficient (ICC), standard error of measurement (SEM), limits of agreement, weighted kappa or the Svensson method. RESULTS Several of the physical activity questionnaires had relatively low test-retest reliability, including the comprehensive questionnaires (IPAQ-SF and PASE). Total physical activity according to IPAQ-SF had an ICC value of 0.46 (95% confidence interval [CI], 0.21-0.66) and SEM was 2891 MET-min/week. The PASE total score had an ICC value of 0.66 (95% CI, 0.46-0.79), whereas the SEM was 30 points. The single-item scales of SGPALS-past six months (SGPALS-6 m) and HOET question 1 (HOET-q1) with longer time frames (6 or 12 months, respectively) showed better results. Weighted kappa values were 0.64 (95% CI, 0.45-0.83) for SGPALS-6 m and 0.60 (95% CI, 0.39-0.80) for HOET-q1, whereas the single-item questions with a shorter recall period had kappa values < 0.40. CONCLUSIONS Single-item questions with a longer time frame (6 or 12 months) for physical activity were shown to be more reliable than multi-item questionnaires such as the IPAQ-SF and PASE in individuals with Parkinson's disease without cognitive impairments. There is a need to develop a core outcome set to measure physical activity in people with Parkinson's disease, and there might be a need to develop new physical activity questionnaires.

Abstract
Mitochondrial dysfunction is one of the crucial factors involved in PD’s pathogenicity, which emerges from a combination of genetic and environmental factors. These factors cause differential molecular expression in neurons, such as varied transcriptional regulation of genes, elevated oxidative stress, α‐synuclein aggregation and endogenous neurotoxins release, which induces epigenetic modifications and triggers energy crisis by damaging mitochondria of the dopaminergic neurons (DN). So far, these events establish a complicated relationship with underlying mechanisms of mitochondrial anomalies in PD, which has remained unclear for years and made PD diagnosis and treatment extremely difficult. Therefore, in this review, we endeavored to discuss the complex association of epigenetic modifications and other associated vital factors in mitochondrial dysfunction. We propose a hypothesis that describes a vicious cycle in which mitochondrial dysfunction and oxidative stress act as a hub for regulating DA neuron's fate in PD. Oxidative stress triggers the release of endogenous neurotoxins (CTIQs) that lead to mitochondrial dysfunction along with abnormal α‐synuclein aggregation and epigenetic modifications. These disturbances further intensify oxidative stress and mitochondrial damage, amplifying the synthesis of CTIQs and works vice versa. This vicious cycle may result in the degeneration of DN to hallmark Parkinsonism. Furthermore, we have also highlighted various endogenous compounds and epigenetic marks (neurotoxic and neuroprotective), which may help for devising future diagnostic biomarkers and target specific drugs using novel PD management strategies.

Abstract
BACKGROUND Fatigue is common in Parkinson's Disease, but few effective treatments are available for it. Exploring triggers and alleviating factors, including effects of exercise, could inform development of management strategies for Parkinson's Disease fatigue. OBJECTIVES To examine triggers and alleviating factors for fatigue reported by individuals with Parkinson's Disease, including perceived effect of exercise. METHODS A sample of individuals with self-reported Parkinson's Disease participating in the study Fox Insight were administered an online survey. The survey included the Parkinson's Fatigue Scale, the Physical Activity Scale for the Elderly, and multiple-choice questions about triggers and alleviating factors for fatigue. RESULTS Among the sample of 1,029 individuals with Parkinson's disease, mean (standard deviation (SD)) age was 67.4 (9.3) years, 44.0% were female. Parkinson's Fatigue Scale score ranged from 16-80, mean (SD) 48.8 (16.2). Poor sleep (62.1%) and physical exertion (45.1%) were frequently reported triggers for fatigue. Coping strategies including sitting quietly (58.1%), laying down with or without napping, and exercise (20%). Physical Activity Scale for the Elderly scores were higher in those who reported that exercise alleviated their fatigue (49.7%) compared to those who reported it worsened their fatigue (18.9%) (mean (SD) score 158.5 (88.8) vs 119.8 (66.6) respectively; p<0.001). CONCLUSIONS Several behavioral and environmental triggers and alleviating strategies for fatigue are reported by individuals with Parkinson's disease. Many feel that exercise alleviates fatigue, though the relationship between exercise and fatigue in Parkinson's Disease appears complex. This exploratory study may inform future development of treatments or coping strategies for Parkinson's disease fatigue.

Abstract
Parkinson’s disease (PD) exhibits systemic effects on the human metabolism, with emerging roles for the gut microbiome. Here, we integrate longitudinal metabolome data from 30 drug-naive, de novo PD patients and 30 matched controls with constraint-based modeling of gut microbial communities derived from an independent, drug-naive PD cohort, and prospective data from the general population. Our key results are (1) longitudinal trajectory of metabolites associated with the interconversion of methionine and cysteine via cystathionine differed between PD patients and controls; (2) dopaminergic medication showed strong lipidomic signatures; (3) taurine-conjugated bile acids correlated with the severity of motor symptoms, while low levels of sulfated taurolithocholate were associated with PD incidence in the general population; and (4) computational modeling predicted changes in sulfur metabolism, driven by A. muciniphila and B. wadsworthia, which is consistent with the changed metabolome. The multi-omics integration reveals PD-specific patterns in microbial-host sulfur co-metabolism that may contribute to PD severity. Longitudinal metabolomics reveal disturbed transsulfuration in Parkinson’s disease Metabolic modeling of gut microbiomes show altered microbial sulfur metabolism Changed microbial sulfur metabolism is linked to B. wadsworthia and A. muciniphila Taurine-conjugated bile acids are associated with incident Parkinson’s disease

Abstract
Increasing evidence points to biological sex as an important factor in the development and phenotypical expression of Parkinson’s disease (PD). Risk of developing PD is twice as high in men than women, but women have a higher mortality rate and faster progression of the disease. Moreover, motor and nonmotor symptoms, response to treatments and disease risk factors differ between women and men. Altogether, sex-related differences in PD support the idea that disease development might involve distinct pathogenic mechanisms (or the same mechanism but in a different way) in male and female patients. This review summarizes the most recent knowledge concerning differences between women and men in PD clinical features, risk factors, response to treatments and mechanisms underlying the disease pathophysiology. Unraveling how the pathology differently affect the two sexes might allow the development of tailored interventions and the design of innovative programs that meet the distinct needs of men and women, improving patient care.

What Determines Spontaneous Physical Activity in Patients with Parkinson's Disease? J Clin Med 2020; 9:jcm9051296.

Abstract
Physical activity (PA) is a factor that may have an influence on the symptoms of Parkinson's disease (PD). The aim of this study was to identify the potential determinants of spontaneous PA in a PD patient group. A total of 134 PD patients aged 65.2 ± 9.2 years with a Hoehn-Yahr scale score ≤4 and a Mini Mental State Examination (MMSE) score ≥24 were examined. For the study's purposes, the authors analyzed age, sex, education, history of PD, dopaminergic treatment, the severity of PD symptoms using Unified Parkinson's Disease Rating Scale (UPDRS), and Hoehn-Yahr scale. Additionally, all participants were evaluated through a set of scales for specific neuropsychiatric symptoms including depression, anxiety, apathy, fatigue, and sleep disorders. A linear regression analysis was used with backward elimination. In the total explanatory model, for 12% of the variability in activity (R2 = 0.125; F(16.133) = 2.185; p < 0.01), the significant predictor was starting therapy with the dopamine agonist (DA) (β= 0.420; t= 4.068; p = 0.000), which was associated with a longer duration of moderate PA. In the total explanatory model, for more than 13% of the variance in time spent sitting (R2 = 0.135; F(16.130) = 2.267; p < 0.01), the significant predictors were secondary education and the results of the UPDRS. The patients with secondary and vocational education, those starting treatment with DA and those with a less severe degree of Parkinson's symptoms (UPDRS), spent less time sitting in a day. It is possible to identify determinants of spontaneous PA. It may elucidate consequences in terms of influence on modifiable conditions of PA and the proper approach to patients with unmodifiable PA factors.

Abstract
The evidence demonstrating the benefits of exercise is indisputable for healthy subjects, and more recently, it is growing for Parkinson's disease (PD) patients. Due to its easy access, low cost, social facilitation and, above all, the symptomatic effect, clinical exercise may have a profound impact on PD management. Especially considering that in recent decades there have been no major advances from the pharmacological point of view. Despite this, clinical exercise use it stills limited by the existent flaws in the available evidence supporting its use and guiding its prescription as a PD therapeutic intervention. We believe that a approach from the most relevant scientific and clinical fields is crucial to establish the use of clinical exercise in PD patients' routine care. Therefore, in this viewpoint, we aim to highlight the importance of clinical exercise as a therapeutic intervention in PD, and particularly of the benefits of applying sports science principles to potentiate the use of clinical exercise as a therapeutic intervention in PD management.

Abstract
Mild cognitive impairment (MCI) is a common feature in Parkinson's Disease (PD), even at the time of diagnosis. Some levels of heterogeneity in nature and severity of cognitive impairment and risk of conversion to Parkinson's Disease Dementia (PDD) exist. This brief overview summarized the current understanding of MCI in PD, by considering the following major points: historical development of the clinical entity, evaluation, epidemiology, predictors and outcomes, neuroimaging findings, pathophysiology, treatment, and pharmacological and non-pharmacological intervention. MCI in PD represents a concept in evolution and plays a pivotal role in advancing our understanding of the disease mechanisms, with the ultimate goal of building effective strategies to prevent conversion into PDD. Challenges for future research are also discussed.

Abstract
BACKGROUND Exercise improves balance in Parkinson disease (PD), yet the majority of people with the diagnosis are physically inactive. Insights gained from understanding how people with PD (PwPD) make sense of their symptoms and their ability to control them may inform the communication strategies and motivational approaches adopted by physical therapists. To our knowledge, no previous study has qualitatively explored how PwPD perceive the concept of balance and the beliefs they hold concerning their ability to affect balance. OBJECTIVE This study aimed to explore the meaning of balance for PwPD and the beliefs they hold regarding their ability to influence their balance in everyday life. DESIGN The design was a qualitative study with an inductive approach. METHODS In-depth interviews were conducted with 18 participants with PD (age range 46-83 years, Hoehn and Yahr range 1-4), and transcripts were analyzed using qualitative content analysis. RESULTS Five main themes emerged from the analysis: remaining in control over the body, adapting behavior to deal with uncertainty, directing focus to stay 1 step ahead, resilience as a defense, and exercise beliefs and reservations. Interpretation of the underlying patterns in the main themes yielded the overarching theme of focus and determination to regain control over shifting balance. CONCLUSIONS The concept of balance was perceived as both bodily equilibrium and mind-body interplay and was described in the context of remaining in control over one's body and everyday life. Cognitive resources were utilized to direct focus and attention during balance-challenging situations in a process involving internal dialogue. Even participants who did not express beliefs in their ability to affect balance through exercise used psychological resilience to counter the challenges of impaired balance.

A secret that underlies Parkinson's disease: The damaging cycle. Neurochem Int 2019; 129:104484.

Abstract
Parkinson's disease (PD) is a movement disorder, and its common characteristics include the loss of dopaminergic neurons and the accumulation of a special type of cytoplasmic inclusions called Lewy bodies in the substantia nigra pars compacta, which are more prevalent in the elderly. However, the pathophysiology of PD is still elusive. In this review, we summarized five common factors involved in PD, namely, (i) oxidative stress, (ii) mitochondrial dysfunction, (iii) inflammation, (iv) abnormal α-synuclein, and (v) endogenous neurotoxins, and proposed a hypothesis involving a damaging cycle. Oxidative stress-triggered aldehydes react with biogenic amines to produce endogenous neurotoxins. They cause mitochondrial dysfunction and the formation of inflammasomes, which induce the activation of neuroglial cells and the infiltration of T lymphocytes. The synergistic effect of these processes fosters chronic inflammation and α-synuclein aggregation and further exacerbates the impact of oxidative stress to establish a damaging cycle that eventually results in the degeneration of dopaminergic neurons. This damaging cycle provides an explanation of progressive neuronal death during the pathogenesis of PD and provides new potential targets beneficial for developing new drugs and approaches for clinical neuroprotection.

Parkinsonism Relat Disord 2019; 62:68-72.

Abstract
OBJECTIVE Associations between cognition and nigrostriatal dopaminergic deficits in Parkinson's disease have been documented in the literature, but are incompletely understood. Here we studied the extent to which physical activity mediates the relationship between striatal dopamine transporter availability and global cognition among patients with Parkinson's disease. METHODS Data from 174 patients from a multi-center study were analyzed using regression-based mediation analysis. Striatal dopamine transporter binding ratio (SBR), Physical Activity Scale for Elderly (PASE), and Montreal Cognitive Assessment (MoCA) were used to evaluate patients' dopamine transporter availability (DAT), physical activity, and global cognition respectively at the time of testing. Confidence intervals (CI) of 95% were established using a bootstrapping approach to test the statistical significance of the direct, indirect (i.e., mediation), and total effects of the mediation model. RESULTS As hypothesized, the positive mediating effect of physical activity in the association between DAT and global cognition was significant, while adjusting for age (95% CI [0.0030, 0.3942]). Specifically, higher SBRs were positively associated with PASE scores, which in turn, were positively associated with MoCA scores. Secondary analyses revealed a similar positive mediation effect of physical activity for DAT in the caudate and putamen separately (95% CI [0.0377, 0.4231] and [0.0211, 1.1000], respectively). CONCLUSION We report that the relationship of dopamine transporter availability with global cognition in Parkinson's disease is mediated by physical activity. Pending further research for specific recommendations, interventions to increase physical activity as tolerated should be considered in patients with Parkinson's disease.

Effect of NAC treatment and physical activity on neuroinflammation in subchronic Parkinsonism; is physical activity essential? J Neuroinflammation 2018; 15:328. [PMID: 30477535 PMCID: PMC6260767 DOI: 10.1186/s12974-018-1357-4] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2018] [Accepted: 10/31/2018] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND Neuroprotective strategies are becoming relevant to slow down dopaminergic cell death and inflammatory processes related to the progressive neurodegeneration in Parkinson's disease (PD). Interestingly, among others, physical activity (PA) or anti-oxidant agents (such as N-acetyl-L-cysteine, NAC) are common therapeutic strategies. Therefore, this study aims to analyze if there is a synergistic effect of physical activity along with NAC treatment on dopaminergic degeneration and neuroinflammatory response in a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced Parkinsonism model after subchronic intoxication. METHODS To ascertain this possibility, 48 8-week-old male mice (C57BL/6 strain) were used. Twenty four of them were placed individually in cages where voluntary physical activity was automatically monitored during 30 days and were divided into groups: (i) control; (ii) NAC; (iii) MPTP, and (iv) MPTP+NAC. The other 24 mice were divided into the same four groups but without physical activity. RESULTS The data collected during the treatment period showed that there was an overall increase in the total running distance in all groups under physical activity, including Parkinsonian animals. However, the monitoring data per day showed that the activity routine by MPTP and MPTP+NAC groups was disrupted by alterations in the circardian rhythm because of MPTP intoxication. Results from post-mortem studies in the substantia nigra pars compacta (SNpc) showed significant decrease in the number of TH+ cells in all MPTP groups. Moreover, TH+ expression in the striatum was significantly decreased in all MPTP groups. Thus, PA + NAC treatment do not protect dopaminergic neurons against a subchronic intoxication of MPTP. Regarding glial response, the results obtained from microglial analysis do not show significant increase in the number of Iba-1+ cell in MPTP+NAC and MPTP+PA + NAC. In the striatum, a significant decrease is observed only in the MPTP+NAC group compared with that of the MPTP group. The microglial results are reinforced by those obtained from the analysis of astroglial response, in which a decrease in the expression of GFAP+ cells are observed in MPTP+NAC and MPTP+PA + NAC compared with MPTP groups both in the SNpc and in the striatum. Finally, from the study of the astroglial response by the co-localization of GFAP/S100b, we described some expression patterns observed based on the severity of the damage produced by the MPTP intoxication in the different treated groups. CONCLUSIONS These results suggest that the combination of physical activity with an anti-oxidant agent does not have a synergistic neuroprotective effect in the nigrostriatal pathway. Our results show a potential positive effect, only due to NAC treatment, on the neuroinflammatory response after subchronic MPTP intoxication. Thus, physical activity is not essential, under these conditions. However, we believe that physical activity, used for therapeutic purposes, has a beneficial long-term effect. In this line, these results open the door to design longer studies to demonstrate its promising effect as neuroprotective strategy.

Treadmill Exercise Attenuates L-DOPA-Induced Dyskinesia and Increases Striatal Levels of Glial Cell-Derived Neurotrophic Factor (GDNF) in Hemiparkinsonian Mice. Mol Neurobiol 2018; 56:2944-2951.

Abstract
Exercise can act as a disease-modifying agent in Parkinson's disease (PD), and we have previously demonstrated that voluntary exercise in running wheels during 2 weeks normalizes striatopallidal dopaminergic signaling and prevents the development of L-DOPA-induced dyskinesia (LID) in C57BL/6 mice. We now tested whether LID in Swiss albino mice could be attenuated by treadmill-controlled exercise alone or in combination with the reference antidyskinetic drug amantadine. The daily intraperitoneal (i.p.) treatment with three different doses of L-DOPA/benserazide (30/12.5, 50/25, or 70/35 mg/kg) during 3 weeks induced increasing levels of LID scores in hemiparkinsonian Swiss albino mice previously lesioned with a unilateral intrastriatal injection of 6-hydroxydopamine (6-OHDA, 10 μg). Then, we addressed the antidyskinetic effects of treadmill-controlled exercise by comparing LID, induced by L-DOPA/benserazide (50/25 mg/kg, i.p.) during 4 weeks, in sedentary and daily exercised mice. Exercise reduced LID and improved motor skills of dyskinetic mice, as indicated by decreased contralateral bias, increase in maximal load test, and latency to fall in rotarod. The antidyskinetic effect of amantadine (60 mg/kg, i.p.) was only observed in sedentary mice, indicating the absence of synergistic antidyskinetic effect of the combination of treadmill exercise plus amantadine. Finally, Western blot analysis unraveled an ability of exercise to increase the striatal immunocontent of glial cell-derived neurotrophic factor (GDNF), apart from normalizing striatal levels of tyrosine hydroxylase. These findings show that controlled treadmill exercise attenuates LID and provide the first indication that the antidyskinetic effects of treadmill exercise may involve increased striatal GDNF levels.

Abstract
Autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) is a neuromuscular disorder caused by the mutation of the SACS gene. Clinical symptoms of this disease include progressive ataxia, spasticity, and peripheral neuropathy. Similar to other neuromuscular disorders, these patients are prone to physical deconditioning which may lead to a loss of functional capacity. This paper aims to evaluate the impact of a training program on the physical fitness and the functional capacity of ARSACS patients. Twelve patients (age: 28.1 ± 8.2 years) participated in this study. They followed an eight-week training program including physical activities, strength-power and aerobic training. Compared to the initial evaluation, measures of physical fitness and functional capacity were significantly improved (p ≤ 0.05) for 11 of the 12 tests. Positive gains were also observed for fall frequency and for upper-limb incoordination. This paper supports the importance of a training program for ARSACS patients in order to improve their quality of life. Through these types of interventions, it may be possible to slow down the progression of the disease and help maintain functional capacity.
