Filter by:The goal of this clinical trial is to determine the relative efficacy of fMRI model guided Transcranial Direct Current Stimulation (mgTDCS) in improving the depressive symptoms of patients with Parkinson's Disease (PD). The main questions it aims to answer are: 1) Can the use of mgTDCS significantly improve the self-reported level of depression and apathy in patients with PD from pre-intervention to post-intervention compared to a sham control? 2) Can the use of mgTDCS significantly normalize the cortical eeg alpha asymmetry so commonly seen in depressed patients compared to sham mgTDCS? 3) Can the use of mgTDCS significantly improve scores on neuropsychological tests of working memory?
Phase I a/b SAD/MAD study to evaluate safety and tolerability of LBT-3627 in both healthy volunteers and Parkinson's patients.
Habitual adherence to a predominantly plant-based diet, rich in low-processed food (LPF) has been associated with a reduced risk for development and slower progression of Parkinson's Disease (PD). This could be due to neuroprotective effects by modulation of the gut microbiota and decreased neuronal and metabolic inflammation. So far, the effect of a predominantly plant-based LPF-diet on the microbiome-immune-brain axis in patients with PD remains unknown. In addition, the influence of dietetic measures on the gut microbiome is variable and may depend on (long-term) adherence as well as on PD-specific factors and lifestyle. The investigators hypothesize that compared to an average German diet, the predominantly plant-based New Nordic LPF-diet, as a culturally adapted diet, which is rich in fermentable fiber and phytochemicals, will have beneficial effects on the gut microbiome of patients with PD by increasing the abundance of short-chain fatty acid (SCFA)-producing bacteria (primary outcome) and will improve gut motility, metabolic resilience, and inflammation (secondary outcomes). Furthermore, the investigators postulate that a patient-centered dietary intervention program, including a multifaceted patient education and supported by a web-application, will lead to high adherence as a key determinant of long-term changes in the gut microbiome. This dietary intervention will be accepted by patients as a low-threshold treatment that balances personal benefits, therapeutic barriers and ethical concerns of early risk disclosure in PD.
Investigation of tenapanor as a potential treatment for synucleinopathy-associated constipation
Parkinson's disease was first described in history in 1817 by James Parkinson in his monograph "An essay on swinging palsy", and today it is the 2nd most common neurodegenerative disease after Alzheimer's, affecting approximately 6.1 million people. Its main histopathological feature is the decrease in dopaminergic secretion in the basal ganglia and there are three cardinal findings: Bradykinesia, Tremor, Rigidity. Although joint and skeletal deformities are seen in approximately 70% of Parkinson's patients, they are not adequately evaluated and cause significant functional disability and chronic pain, independent of motor symptoms.Musculoskeletal pathologies seen in Parkinson's patients can be classified as: musculoskeletal pain, articular problems, postural problems and bone mineralization defects. The shoulder girdle is a joint with complex and delicate function, consisting of four joints (glenohumeral, sternoclavicular, acromioclavicular and scapulothoracic), supporting muscles and periarticular ligaments, which seriously affects the patient's quality of daily life and function. Although magnetic resonance imaging (MRI) is the best imaging tool in the diagnosis of musculoskeletal system pathologies, it is quite sensitive to artifact-forming motion. Ultrasound (US) imaging is widely used in the evaluation of rotator cuff muscles, biceps muscle and glenohumeral joint pathologies and has many advantages over MRI, such as providing fast, cheap and dynamic imaging. Although many studies have proven that shoulder girdle musculoskeletal pathologies such as bicipital tendinitis, m.supraspinatus tendinosis, subacromial/subdeltoid bursitis, subacromial impingement syndrome, and adhesive capsulitis are seen more frequently in Parkinson's patients by ultrasonographic imaging, these shoulder girdle pathologies seen in Parkinson's patients are more common. The risk factors for pathologies have not been defined. In this study, we aimed to determine the ultrasonographic findings and risk factors of shoulder pathologies in Parkinson's patients and to investigate the effects of shoulder pathologies on quality of daily life, physical activity, falls and balance.
The purpose of this study is to understand whether people with Parkinson's Disease and depression have improvement in their symptoms after psilocybin therapy.
The study aims to verify whether the use of a specific footwear providing increased plantar feedback (plantar feedback shoes) could improve gait parameters, postural control and functional performances in people with Parkinson's disease. Specifically, the aims are: - To evaluate the acute effect of plantar feedback shoes, by comparing gait, functional and postural performances in three conditions: neutral shoes, barefoot, and plantar feedback shoes; - To evaluate the effect of four weeks of plantar feedback shoes, on gait, functional and postural performances. Participants will undergo a comprehensive neurological examination, with administration of disease-specific scales (UPDRS III part 3, NFOG-q, LEDD, DASS-21). At each assessment the participants will perform an inertial gait analysis, a static posturography, and will undergo functional capacity assessments (TUG, 2MWT, 5-STST, 10- mFW).
The goal of this clinical trial is to learn if a nature-based program has positive effects on the physical and psychosocial health in a group of participants with Parkinson's disease. The main questions it aims to answer are: Will the program improve: - The physical outcomes such as mobility, strength and balance? - The psychosocial health outcomes? Participants will: - Be assessed before and after the program; - Participate in one session per week of the intervention.
The goal of this observational study is to describe non motor symptoms in a prospective study of patients with Parkinson's disease associated to glucocerebrosidase (GBA-PD) mutations. The main questions it aims to answer are: - Do GBA-PD patients have a greater burden of non motor symptoms? - How do these non motor symptoms evolve during a prospective follow up of two years? - Are these non motor symptoms different from those that affect Parkinson's disease patients without glucocerebrosidase mutations (non GBA-PD), in prevalence, severity and type? - Do these non motor symptoms correlate with objective measures such as posturography or speed reaction tests? - Is there a test or combination of tests that can predict the appearance of early or severe non motor symptoms? For this reason researchers will compare the GBA-PD group of patients with a group of non mutated GBA Parkinson disease. Participants will undergo a neurological and neuropsychological evaluation with different tests in subsequent visits for a total of 2 years.
Many people living with neurodegenerative conditions like dementia, motor neuron disease (MND), multiple sclerosis (MS), and Parkinson's disease (PD), suffer from speech problems. Using common digital technologies such as smartphone apps, the investigators can record and analyse speech in detail to provide new information for people living with these conditions, researchers, and healthcare professionals. This study will investigate the use of these digital speech recordings to help diagnose and monitor these conditions. To take part, participants will have either a diagnosis of dementia, motor neuron disease, Parkinson's disease or Multiple Sclerosis, OR they will have no diagnosis of a neurological condition. Researchers will compare people with a diagnosis of a Neurological condition to those without.
