Since the neuroprotective effects of coffee and tobacco on Parkinson’s disease have been reported more than 50 years ago, clinical studies using caffeine and nicotine that were presumed as effective components of coffee and tobacco, respectively, are being actively executed. However, most results failed to show significant differences between the tested and control groups, and some studies revealed contradictory results to the neuroprotection. The reason for this might be that the effective components are something other than nicotine or caffeine, and/or differences to design the clinical trials such as patients recruiting, prescribed amount and period, and analyzed criteria etc. The review summarizes recent results for effect of coffee, tobacco as well as alcohol, representatives of indulgent food, on Parkinson’s disease.

Parkinson’s disease (PD) is a common and complex neurodegenerative disease; the pathogenesis of which is still uncertain. Exosomes, nanosized extracellular vesicles, have been suggested to participate in the pathogenesis of PD, but their role is unknown. Here, a metabolomic analysis of serum and brain exosomes showed differentially expressed metabolites between 1-Methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine hydrochloride- (MPTP-) induced PD mice and control mice, such as oxidized lipids, vitamins, and cholesterol. These metabolites were enriched in coenzyme, nicotinamide, and amino acid pathways related to PD, and they could be served as preclinical biomarkers. We further found that blood-derived exosomes from healthy volunteers alleviated impaired motor coordination in MPTP-treated mice. Results from immunohistochemistry and western blotting indicated that the loss of dopaminergic neurons in substantia nigra and striatum of PD model mice was rescued by the exosome treatment. The exosome treatment also restored the homeostasis of oxidative stress, neuroinflammation, and cell apoptosis in the model mice. These results suggest that exosomes are important mediators for PD pathogenesis, and exosomes are promising targets for the diagnosis and treatment of PD.

To date, no drug has been proven to be neuroprotective or disease-modifying for Parkinson’s disease (PD) in clinical trials. Here, we aimed to assess preclinical evidence of Ginsenosides-Rg1 (G-Rg1), a potential neuroprotectant, for experimental PD and its possible mechanisms. Eligible studies were identified by searching six electronic databases from their inception to August 2016. Twenty-five eligible studies involving 516 animals were identified. The quality score of these studies ranged from 3 to 7. Compared with the control group, two out of the 12 studies of MPTP-induced PD showed significant effects of G-Rg1 for improving the rotarod test (P<0.01), two studies for improving the swim-score values (P<0.01), six studies for improving the level of TH protein expression (P<0.01), and two studies for increasing the expression of TH mRNA in the substantia nigra of mice (P<0.01). The studies reported that G-Rg1 exerted potential neuroprotective effects on PD model through different mechanisms as antineuroinflammatory activities (n=10), antioxidant stress (n=3), and antiapoptosis (n=11). In conclusion, G-Rg1 exerted potential neuroprotective functions against PD largely by antineuroinflammatory, antioxidative, and antiapoptotic effects. G-Rg1 as a promising neuroprotectant for PD needs further confirmation by clinical trials.

Background. It is currently impossible to diagnose Parkinson’s disease (PD) in the premotor phase even though at the time of motor symptom onset the number of already degenerated dopaminergic substantia nigra neurons is considerable. Degeneration of the dorsal nucleus of the vagus nerve (VN) has been reported early in the disease course, and it could lead to impaired function of the VN, resulting in certain nonmotor symptoms of PD. Therefore, we raised a hypothesis that the loss of VN neurons could result in a smaller diameter of the VN among PD patients. Methods. 20 PD patients and 20 age- and gender-matched individuals without any neurodegenerative disease were enrolled in a pilot study. The diameters of the right and left VNs were measured using ultrasonography, their average was calculated, and the narrower VN diameter was noted separately. Results. No difference was found between the PD and control groups neither in the average VN diameter (mean 1.17; 95% confidence interval (CI) 1.10–1.24 vs. 1.13; 1.07–1.18, mm; p=0.353) nor in the narrower VN diameter (mean 1.11; 95% confidence interval (CI) 1.02–1.20 vs. 1.07; 1.02–1.13, mm; p=0.421). The narrower VN diameter and the average VN diameter were not able to distinguish between PD patients and controls (area under curve (AUC) = 0.588, 95% CI = 0.408–0.767, and p=0.344; and AUC = 0.578, 95% CI = 0.396–0.759, and p=0.402). Conclusions. To conclude, no differences were found in VN diameter between the PD and control groups. Therefore, our data do not support the hypothesis that PD could be associated with a smaller diameter of the VN.

The purpose of this study was to investigate the effects of Health Qigong on the treatment and releasing symptoms of Parkinson’s disease (PD). Fifty-four moderate PD patients (N=54) were randomly divided into experimental and control groups. Twenty-eight PD patients were placed in the experimental group in which the prescribed medication plus Health Qigong exercise will be used as intervention. The other 26 PD patients as the control group were treated only with regular medication. Ten-week intervention had been conducted for the study, and participants completed the scheduled exercises 5 times per week for 60 minutes each time (10 minutes for warm-up, 40 minutes for the exercise, and 10 minutes for cooldown). Data which included the muscle hardness, one-legged blind balance, physical coordination, and stability was collected before, during, and after the intervention. Comparisons were made between the experimental and control groups through the Repeated Measures ANOVA. The results showed that PD patients demonstrate a significant improvement in muscle hardness, the timed “up and go,” balance, and hand-eye coordination (the turn-over-jars test). There were no significant differences between the two groups in gender, age, and course of differences (P<0.05). The study concluded that Health Qigong exercises could reduce the symptoms of Parkinson’s disease and improve the body functions of PD patients in both the mild and moderate stages. It can be added as an effective treatment of rehabilitation therapy for PD.

Background: Kinesiophobia can be an obstacle to physical and motor activity in patients with Parkinson’s disease (PD). PD affects patients’ independence in carrying out daily activities. It also impacts a patient’s biopsychosocial well-being. The objective of this study was to analyze the levels and scores of kinesiophobia in PD patients and compare them with healthy volunteers. Methods: We deployed a case-control study and recruited 124 subjects (mean age 69.18 ± 9.12). PD patients were recruited from a center of excellence for Parkinson’s disease (cases n = 62). Control subjects were recruited from the same hospital (control n = 62). Kinesiophobia total scores and categories were self-reported using the Spanish version of the Tampa Scale of Kinesiophobia (TSK-11). Results: Differences between cases and control groups were analyzed using the Mann–Whitney U test. Statistically significant differences (p < 0.05) were shown between groups when comparing kinesiophobia categories (or levels) and total scores, revealing higher kinesiophobia symptoms and levels in PD patients. All of the PD patients reported some degree of kinesiophobia (TSK-11 ≥ 18), while the majority of PD patients (77.3%) had kinesiophobia scores rated as moderate to severe (TSK-11 ≥ 25). On the other hand, ~45.1% of controls reported no or slight kinesiophobia and 53.2% reported moderate kinesiophobia. Conclusions: Total kinesiophobia scores were significantly higher in PD patients compared with healthy controls, with moderate to severe kinesiophobia levels prevailing in PD patients. Therefore, individuals living with PD should be evaluated and controlled in order to detect initial kinesiophobia symptoms.

Parkinson’s Disease (PD) is a neurological disease characterized by the progressive degeneration of the nigrostriatal dopaminergic pathway with consequent loss of neurons in the substantia nigra pars compacta and dopamine depletion. The cytoplasmic inclusions of α-synuclein (α-Syn), known as Lewy bodies, are the cytologic hallmark of PD. The presence of α-Syn aggregates causes mitochondrial degeneration, responsible for the increase in oxidative stress and consequent neurodegeneration. PD is a progressive disease that shows a complicated pathogenesis. The current therapies are used to alleviate the symptoms of the disease without changing its clinical course. Recently, phytocompounds with neuroprotective effects and antioxidant properties such as caffeine have aroused the interest of researchers. The purpose of this review is to summarize the preclinical studies present in the literature and clinical trials recorded in ClinicalTrial.gov, aimed at illustrating the effects of caffeine used as a nutraceutical compound combined with the current PD therapies. Therefore, the preventive effects of caffeine in the neurodegeneration of dopaminergic neurons encourage the use of this alkaloid as a supplement to reduce the progress of the PD.

BACKGROUND Background: Although physical exercises can help older adults with Parkinson’s disease to retain their mobility function, older adults are less motivated to attend repeated and intensive physical training. Exergaming-based interventions have the potential to provide a more engaged and enjoyable therapy. However, few meta-analysis studies discussed the effectiveness of exergaming-based interventions on the mobility performance of older adults with Parkinson’s disease. OBJECTIVE Objective: A systematic review and meta-analysis of randomized controlled trials (RCTs) were conducted to examine the effectiveness of exergaming-based interventions on mobility performance in older adults with Parkinson’s disease. METHODS Methods: Seven databases (Web of Science, Medline, Academic Search Premier, CINAHL Complete, PsycINFO, PsychARTICLE, and PubMed) were searched to identify the RCTs which examined the effectiveness of exergaming on the mobility performance of older adults with Parkinson’s disease up to September 2021. Using meta-analysis, we assessed mobility performance between intervention groups and control groups by comparing basic mobility function with the Timed Up and Go (TUG), walking capability with 6-Minute Walk Test (6MWT), postural balance function with the Berg Balance Scale (BBS), and gait ability with gait velocity, stride length, and the Functional Gait Assessment (FGA). RESULTS Results: After scanning 1110 articles, we identified and meta-analyzed 16 trials, including a total of 508 older adults with Parkinson’s disease. The results revealed statistical differences between intervention groups and control groups in the TUG (MD = -0.87; 95% CI = -1.60 to -0.15; P = .018), 6MWT (MD = 39.56; 95% CI = 1.21 to 77.91; P = 0.043), BBS (MD = 2.28; 95% CI = 1.42 to 3.14; P < .001), and FGA (MD = 1.40; 95% CI = -0.03 to 2.82; P = .054). The detectable clinically difference of the outcomes were discussed and the implications were provided. CONCLUSIONS Conclusions: Exergaming is superior to traditional training in improving PD older adults’ basic mobility skills, walking capability, and postural balance function, while it has an equal effect with traditional physical training in enhancing PD older adults’ gait ability.

Background:Our objective is to examine how persons diagnosed with Multiple Sclerosis (MS) and Parkinson's disease (PD) change residence following disease onset. We hypothesize that persons choose to change residence (locally or regionally) in different ways depending on whether or not they have been diagnosed with MS/PD. We also estimate the effects of residence change on measures of disease prevalence made at several different levels of geography.Methods:Using fee-for service and hospitalization data, we identify cases of MS and PD between 1994 and 2004. Both of these case groups are matched to controls based on age, sex, socioeconomic status and municipality of residence. We tabulate and compare the changes of residence among persons in the case and control groups. We also use these data to estimate the effects that changes in residence have on disease prevalence at three different levels of geography.Results:Both MS and PD patients were more likely to change residence following disease onset compared to groups of matched controls (p<=0.001). Most changes of residence occur within the same municipality. The total magnitude of these changes is small, however, and is unlikely to affect estimates of disease prevalence; over our study period, the largest change in geographical prevalence estimates due to individual changes in residence was about 1%.Conclusions:Persons diagnosed with MS and PD both have mobility characteristics that differ from those of their respective control groups, and in general, are more likely to move to or between Edmonton and Calgary, and less likely to move out of province. However, the balance of mobility characteristics of persons with PD and MS appear unlikely to greatly affect the patterns observed on maps of disease prevalence.

The aim of this study is to analyze executive function and motor symptoms in patients with idiopathic Parkinson's disease (PD). The sample consisted of 44 subjects with PD between the ages of 45 to 75, who were examined consecutively. The subjects were divided into two groups according to the duration of the disease. The control group was composed of spouses, family and accompanying members. Patients included were submitted to motor dysfunction evaluation using the UPDRS. The executive functions modalities analyzed included: operational memory, inhibitory control, planning, cognitive flexibility and inductive reasoning. Significant differences between the experimental and control groups were found in all the executive domains studied. Evidence of tremor, rigidity and bradykinesia correlation with executive dysfunction were not observed. Patients with PD, even in the initial phase of the disease, presented executive dysfunction. The cardinal motor signs of the disease were not correlated with the cognitive dysfunction found.
