Plasma extracellular vesicles (EVs) containing various molecules, including cytokines, can reflect the intracellular condition and participate in cell-to-cell signaling, thus emerging as biomarkers for Parkinson’s disease (PD). Inflammation may be a crucial risk factor for PD development and progression. The present study investigated the role of plasma EV cytokines as the biomarkers of PD. This cross-sectional study recruited 113 patients with PD, with mild to moderate stage disease, and 48 controls. Plasma EVs were isolated, and the levels of cytokines, including pro-interleukin (IL)-1β, IL-6, IL-10, tumor necrosis factor (TNF)-α, and transforming growth factor (TGF)-β1, were evaluated. Patients with PD had significantly increased plasma EV pro-IL-1β and TNF-α levels compared with controls after adjustment for age and sex. Despite the lack of a significant association between plasma EV cytokines and motor symptom severity in patients with PD, cognitive dysfunction severity, assessed using the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment, was significantly associated with plasma EV pro-IL-1β, IL-6, IL-10, and TNF-α levels. This association was PD specific and not found in controls. Furthermore, patients with PD cognitive deficit (MMSE < 26) exhibited a distinguished EV cytokine profile compared to those without cognitive deficit. The findings support the concept of inflammatory pathogenesis in the development and progression of PD and indicate that plasma EV cytokines may serve as PD biomarkers in future.

Background. The early detection of wearing-off in Parkinson disease (DEEP) observational study demonstrated that women with Parkinson’s disease (PD) carry an increased risk (80.1%) for wearing-off (WO). This post hoc analysis of DEEP study evaluates gender differences on WO and associated phenomena.Methods. Patients on dopaminergic treatment for ≥1 year were included in this multicenter observational cross-sectional study. In a single visit, WO was diagnosed based on neurologist assessment as well as the use of the 19-item wearing-off questionnaire (WOQ-19); WO was defined for scores ≥2. Post hoc analyses were conducted to investigate gender difference for demographic and clinical features with respect to WO.Results. Of 617 patients enrolled, 236 were women and 381 were men. Prevalence of WO was higher among women, according to both neurologists’ judgment (61.9% versus 53.8%,P=0.045) and the WOQ-19 analysis (72.5% versus 64.0%,P=0.034). In patients with WO (WOQ-19), women experienced ≥1 motor symptom in 72.5% versus 64.0% in men and ≥1 nonmotor symptom in 44.5% versus 36.7%, in men.Conclusions. Our results suggest WO as more common among women, for both motor and nonmotor symptoms. Prospective studies are warranted to investigate this potential gender-effect.

Background: Fatigue corresponds to a non-motor symptom of high prevalence in Parkinson’s disease (PD) affecting about one thirdof patients with the disease. This symptom negatively affects daily activities, contributing to the deterioration of the quality of life ofthese subjects. Objectives: To estimate fatigue in PD and to correlate with demographic characteristics, sleep, disease stage, motorfunction and daily activities. Methods: The sample consisted of patients with PD. The following measuring instruments were used for thestudy:Hoehn and Yahr scale, Fatigue Rating Scale, Unified Parkinson’s Disease Rating Scale, Parkinson’s Disease Sleep Scale. Results: Thisstudy highlights the high prevalence of fatigue in subjects with PD, and the screening and treatment of this symptom is extremelyrelevant in clinical practice. There were no significant correlations between fatigue and other variables analyzed. Conclusions: Mostparticipants reported fatigue as a relevant problem, so it is important the use of instruments for fatigue screening in clinical practiceand the need to develop therapies related to this symptom in the PD.

Multiple cognitive deficits have been recognized in many neurological disorders but the specificity of the findings and the relationship to the underlying neuropathology remain obscure. Definitions of dementia have been proposed based on symptom profiles of the cognitive disorder and qualitative differences have been claimed between dementias of different aetiology. Some conditions have been claimed to show patterns of cognitive deficit that are distinguished from dementia and related to specific neuropathology or psychological processes, e.g. frontal lobe deficits in Parkinson's disease. Sometimes, a relationship has been established between certain cognitive deficits and particular neurochemical deficits which has led to the notion of specific drug treatment, e.g. cholinergic deficits and memory failure in Alzheimer's disease. However, these conclusions are often potentially flawed by methodological inadequacies. This critique presents some methodological issues relevant to the study of brain-behaviour and drug-behaviour relationships in syndromes of multiple cognitive deficit, using Parkinson's disease as the model. The following recommendations are made: rigid diagnostic criteria; representative patient groups; avoidance of arbitrary quantitative criteria to limit definitions of dementia; matching of groups for overall level of cognitive impairment in the search for qualitative cognitive differences related to neuropathology or effects of particular drugs; the use of suitable controls in patient groups, neuropsychological tests and treatment regimes; the use of specific quantitative tests of cognition, affect and motor disability; and longitudinal, compared with cross-sectional, study design.

Introduction. Complementary and alternative medicine (CAM) is frequently used by Parkinson’s disease (PD) patients. We sought to provide information on CAM use and efficacy in PD patients in the Denver metro area with particular attention to cannabis use given its recent change in legal status.Methods. Self-administered surveys on CAM use and efficacy were completed by PD patients identified in clinics and support groups across the Denver metro area between 2012 and 2013.Results. 207 patients (age69±11; 60% male) completed the survey. Responses to individual CAM therapy items showed that 85% of respondents used at least one form of CAM. The most frequently reported CAMs were vitamins (66%), prayer (59%), massage (45%), and relaxation (32%). Self-reported improvement related to the use of CAM was highest for massage, art therapy, music therapy, and cannabis. While only 4.3% of our survey responders reported use of cannabis, it ranked among the most effective CAM therapies.Conclusions. Overall, our cross-sectional study was notable for a high rate of CAM utilization amongst PD patients and high rates of self-reported efficacy across most CAM modalities. Cannabis was rarely used in our population but users reported high efficacy, mainly for nonmotor symptoms.

<p><strong><em>Background</em></strong><em>: Parkinson's disease (PD) is a chronic neurodegenerative disease that manifests as movement disorders. Based on motor symptoms, PD is classified into subtypes of tremor and postural instability gait disorders (PIGD). The motor symptoms subtype is a predictor of disease progression, therapeutic response, and quality of life for Parkinson's patients. The purpose of this study is to identify some  factors that influence motor symptoms in Parkinson's disease.</em><strong><em>Methods:</em></strong><em> This research use cross sectional design. Samples were selected by consecutive sampling method that met the inclusion and exclusion criteria. Research subjects were 58 people. Statistical analysis using SPSS. p values &lt;0.05 were considered statistically significant.</em><strong><em>Results:</em></strong><em> This research include 58 patients, 55.2% were men with range of age 63.5 ± 8.5 years old. The mean age at onset was 57.9 ± 9.5 years and duration of disease 6.1 ± 4.6 years. Motor symptoms 53.4% dominant tremor. There was a significant relationship between disease stage and motor symptom subtypes (p &lt;0.001). There is no relationship between the patient's age, age at onset and duration of the disease with motor symptom subtypes.</em><strong><em>Conclusions:</em></strong><em> There is a relationship between disease stage and motor symptom. The patient's age, age at onset and duration of the disease are not related to the motor symptoms of Parkinson's patients.</em></p>

Introduction: Parkinson’s Disease (PD) is a progressive neurodegenerative disorder where the individual over time needs more and more assistance from their caregivers to carry on their life and that causes increasing burden on the caregiver. The burden for the caregiver is affecting them physically, mentally and also on a socioeconomic level. Aim: To examine the factors related to caregiver burden in caregivers of Parkinson’s patients. Materials and Methods: This was a cross-sectional study conducted in Parkinson’s clinic of a Tertiary Care Hospital of Kochi, on 100 Parkinsonism patients and their respective caregivers. Patients were assessed using the Unified PD Rating Scale (UPDRS), Hoehn and Yahr Scale (H&Y) and Mini-Mental State Examination (MMSE). Caregivers were assessed using Zerit’s Caregiver Burden inventory (CBI). Semi structured questionnaire was administered for socio-demographic details. Non parametric tests were done to examine the correlation among various variables. Results: Among the patients and caregivers, mean age was 70.65±7.30 and 67.31±8.56, respectively. Among the patient’s majority were males (n=74) while among caregivers, majority were females (n=73). Mean duration of disease was 6.79±2.68 years, mean caregiver burden score was 65.05±21.79, mean UPDRS score was 21.89±8.74 and had significant positive correlation with caregiver burden. Mean MMSE score was 17.19±4.91. The disease duration and UPDRS score had a significant positive correlation with caregiver burden score. MMSE score had significant negative correlation with caregiver burden score. Conclusion: This study concludes that a patient’s Parkinsonism related disability accounts for majority of caregiver burden. An early identification of factors contributing to stress in caregivers will help to avoid its persistency leading to a better insight in the caregiving role and thus in-patient care.
