Filter by:Popular science summary of the project The purpose of the study is to investigate in a Swedish population how well the investigators' previous ultrasound findings match the final diagnosis (PD, APS or ET) after a particularly long follow-up time, which greatly increases the certainty that the diagnosis does not change more and is thus correct. Furthermore, the investigators want to study whether the initial ultrasound findings have changed during the control interval and whether measurement results regarding the diameter in one of the fluid-filled rooms in the brain (third ventricle) can be correlated with the development of cognitive impairment or dementia later in the course of the disease. For this, this study have got ethical permission to go into the patients' medical records and to call a subgroup back to the clinic to be able to do a new examination and a memory test.
In this study, the investigators will assess the Vagus nerve in two groups: Group 1 which include patients with parkinsonism and group 2 which included age and sex matched healthy control. The aim of the study is: detecting the difference between both groups and correlating the changes in the Vagus nerve cross sectional area with the motor and non motor manifestations of parkinsonism
Parkinson's Disease (PD) affects people universally, including all ethnic and socioeconomic groups, as a highly prevalent neurodegenerative disorder. However, there are several additional challenges for people living with PD in developing countries, especially those with low socioeconomic status. There is limited access to neurological care in Brazil due to an uneven distribution of neurologists and neurological facilities, which is more critical in the poorest regions. In addition, people in these vulnerable communities are more exposed to environmental pollution, including pesticides and metals used in agriculture and mining, respectively. Therefore, reliable data on the prevalence and incidence of PD in Brazil are essential to understand the proportion of this limited access to care for patients with PD, its burden in the region, and the potential role of environmental and lifestyle risk factors in PD. Unfortunately, the literature describes few epidemiological data on PD in Latin America, including Brazil, with an evident need for more information in their regions remarkably different. The investigators will carry out a population-based study in four municipalities in Brazil (Veranópolis-RS, Belém-PA, Jacobina-BA and Candangolândia-DF), comprising distinct communities in terms of ethnic groups, education levels, and environmental and lifestyle exposures, to portray the differences in Brazilian society. The present study will screen all people living in these regions aged 60 and over for parkinsonian symptoms and REM sleep behavior disorder (RBD). At least one neurologist will examine those selected to determine the diagnosis of PD or related disorders. The study also will evaluate a random sample of those individuals with a negative screen. Each participant selected after the screening will undergo clinical assessments and interview with the addition of a comprehensive questionnaire on clinical and sociodemographic data, prodromal symptoms, as well as lifestyle and environmental exposures, including occupational use and non-occupational use of pesticides and metals. An equal sample of blood and hair will be collected from individuals with PD and controls. The study will determine the prevalence of PD and related disorders in these distinct communities. An exploratory analysis also will be performed to determine the association between PD and each variable investigated.
Autonomic dysfunction is common and often underrecognized in Parkinson's disease (PD). Orthostatic hypotension (OH) affects up to a third of PD patients and often coincides with supine hypertension. This co-occurrence complicates pharmacological treatment as treatment of one can negatively affect the other. Head-up tilt sleeping (HUTS) could improve both. This phase II randomized controlled trial (RCT) aims to investigate the efficacy and tolerability of this understudied intervention, leading to optimal implementation strategies.
α-Synucleinopathy is a cluster of neurodegenerative disease with motor and non-motor symptom. However, there is still a lack of research on the treatment for non-motor symptoms of α-synucleinopathy, especially autonomic dysfunctions such as orthostatic hypotension. Efficacy and safety of astragalus for non-motor symptoms of α-synucleinopathy will be assessed by an open-label self-controlled before-and-after study.
The purpose of this project is to investigate whether a 3-week training program involving music beat (serving as a type of rhythmic auditory stimulation) reduces the severity of bradykinesia and dyskinesia in at-risk individuals and schizophrenia patients. It is hypothesized that the program is effective in reducing the severity of bradykinesia and dyskinesia in at-risk individuals and schizophrenia patients.
The prevalence of Multiple System Atrophy (MSA) is reported to be between 3.4 - 4.9 cases per 100,000 population. The estimated average incidence is 0.6 - 0.7 cases per 100,000 people per year. Many patients are not diagnosed properly during their lifetime because of the difficulty in differentiating MSA from other disorders. Approximately 29 - 33% of patients with isolated late onset cerebellar ataxia and 8 - 10% of patients with parkinsonism will develop MSA. There are currently no therapies that can cure or stop the progression of the disease. The current pharmacological therapy is only to relieve symptoms. Mesenchymal stem cells (MSC) are considered an efficient source of cells for therapy, because they can be safely harvested and transplanted to donors or patients, have low immunogenicity, and have broad therapeutic potential. Results from preliminary preclinical and clinical trials indicate the potential of MSC-based treatment in meeting several key aspects of neurodegeneration. Stem cell-based therapy for neurodegenerative diseases aims to stop clinical damage by regenerating and by providing local support for damaged tissue, in addition after transplantation, MSCs have been shown to be capable of penetrating the lesion area and thus have great potential use as a means of administering therapeutic agents. The subjects of this study were patients who experienced possible MSA based on the consensus clinical criteria for MSA. There will be three treatment groups with a total sample of 5 subjects each. Group 1 will receives MSC-Adipose Autologous with doses 2x50 million cells intratechally. Group 2 will receives MSC-Umbilical Cord Allogeneic with doses 2x 50 million cells intratechally. Group 3 will receives MSC-Umbilical Cord Allogeneic with doses 2x50 million cells intratechally and 2x10cc secretome MSC from Adipose Intravenously. Clinical improvement will be evaluated using the UMSARS scale, PET-Scans, MRI, DaTScan, IGF-1, BDNF, Sympathetic skin respons (SSR), EMG, Composite Autonomic Severity Score (CASS), High definition-Optical coherence tomography (HD-OCT), ERG, VEP, Log MAR chart, Ishihara test and side adverse effect on MSC. This study is divided into six timeframes : Before an implantation, First Month after second implantation, Third month after secondary implantation, Sixth month after second implantation, Ninth month after second implantation and Twelve month after second implantation. The differences between the test variables are then used as an indicator to assess clinical improvement within the subjects.
The purpose of this research is to examine effects of movement training with the aid of rhythmic auditory stimulation (RAS) on reducing severity of dyskinesia and bradykinesia in at-risk individuals and schizophrenia patients. The investigators hypothesize that training with the aid of RAS reduced severity of bradykinesia and dyskinesia in at-risk individuals as well as in schizophrenia patients.
The purpose of this study is to determine whether identification of misfolded proteins in the skin will help to determine what sort of parkinsonism someone has. We seek to demonstrate whether someone has a synucleinopathy such as Parkinson's disease (PD), multiple system atrophy (MSA), or dementia with Lewy bodies(DLB), as opposed to a tauopathy such as progressive supranuclear palsy (PSP) or corticobasal degeneration (CBD) or no parkinsonism at all (control).
Objective of the study: To test the efficacy of theta burst cerebellar stimulation on dual task walking in Parkinson's disease using a cross-over design and wearing sensors technology Design: Twenty Parkinson's disease patients with no dementia will be recruited for a cross-over sham-controlled study. Each patient will undergo a sham stimulation or a single session of cerebellar theta burst stimulation with a wash out period of at least 14 days. Each patient will be evaluated before and after stimulation by a battery of gait and movement tests using wearing sensors technology .
