Filter by:People with Parkinson's disease (PD) commonly experience a range of both motor (e.g., bradykinesia, rigidity, tremor, and postural instability) and non-motor (e.g., fatigue, psychiatric and behavioural disturbances, autonomic dysfunction, cognitive impairment, sleep dysfunction and olfactory loss) features. Currently, it is challenging to alleviate these symptoms with first-line treatment, the medications such as levodopa. The CUE1 is a non-invasive device, which is approved for sale in the UK market as a Class I low risk device. It is worn on the sternum or other part of the body such as the forearm and attaches to the skin via an adhesive patch which has been dermatologically tested and approved. The CUE1 delivers pulsing cueing and vibrotactile stimulation to help improve symptoms in people with PD and it has shown to be effective in doing so in previous small case studies. This 9-week feasibility study aims to investigate the feasibility, safety, tolerability and effect of using the CUE1 as an intervention to improve motor and non-motor symptoms in people with PD and related movement disorders. People with clinical diagnosis of idiopathic PD and related disorders including those with progressive supranuclear palsy, multiple system atrophy, corticobasal degeneration, and vascular Parkinsonism as well as atypical dystonias and tremor disorders aged over 18 years old who have the capacity to provide a written consent form to take part in the study, will receive as intervention to wear the CUE1 device at home, on daily basis while carrying out their activities of daily living. Participants will also have to attend four face-to-face appointments of approximately half a day, at weeks -0, -3, -6 and -9 of the study to discuss how they are getting on with using the CUE1 and complete questionnaires on their symptoms, walking, balance, and movement tests as well as a participant's clinical diary.
Progressive supranuclear palsy (PSP), Multiple system atrophy (MSA) and corticobasal syndrome (CBS) are severe neurodegenerative diseases with rapid progression and no effective treatment. Patients quickly succumb to increasing motor and non-motor symptoms and survival ranges from ~3 years to ~10 years. Although PSP, MSA and CBS are rare diseases they constitute a major and mostly unaddressed challenge to health-care providers due to the severity of disease and lack of treatment. The main hypothesis for the NADAPT trial is that oral administration of NR can boost cellular NAD levels in the central nervous system of patients with PSP, MSA and CBS, and rectify metabolism and inhibit neurodegeneration, resulting in delayed disease progression and amelioration of symptoms for these patients. To test whether NR is a neuroprotective therapy for atypical parkinsonism, the investigators will perform the NADAPT clinical trial. The investigators will include 130 patients with Progressive supranuclear palsy (PSP), 165 patients with Multiple system atrophy (MSA) and an indeterminate number of patients with corticobasal syndrome (CBS). The participants will be stratified by disease into three cohorts and randomized to either 3000mg NR daily or placebo. The trial will include patients from all of Norway. Patients will be followed for 78 weeks with both in-clinic visits and decentralized safety measurements and reporting of patient reported outcomes (PROMs). After completion of the 78 weeks follow-up, patients are offered to continue in an open-label NR-only extension study, this extension study will last until follow-up is completed for the last patients in NADAPT.
Study goal: The goal of this prospective head to head comparison is to evaluate the effectiveness of [18F]-MFBG PET in assessing cardiac innervation, comparing it with [123I]-MIBG SPECT The study's primary focus is on distinguishing between Parkinson's disease (PD) and multiple system atrophy (MSA), as well as between dementia with Lewy bodies (DLB) and Alzheimer's disease (AD). Main questions: - Feasibility: How well can [18F]-MFBG PET detect changes in myocardial uptake in PD and DLB compared to the expected normal values in healthy individuals and AD and MSA-P patients? How well can it differentiate between these groups based on the detected changes? - Non-inferiority: Is [18F]-MFBG PET as accurate as [123I]-MIBG SPECT in distinguishing between PD and MSA-P, and between DLB and AD? Participant requirements: For the main study, participants will be required to visit the hospital for 3 or 4 appointments. During these visits, they will undergo a screening visit, MRI brain scan, a comprehensive neurological assessment, [18F]-PE2I PET, [123I]-MIBG SPECT, and [18F]-MFBG PET scans. Additionally, a separate dosimetry study will be conducted, involving healthy subjects who will visit the hospital for a screening visit and undergo [18F]-MFBG PET scans.
This study will assess the safety and efficacy of ATH434 in participants with a clinical diagnosis of Multiple System Atrophy
Despite being studied less than half as frequently, autonomic dysfunction is a greater priority than walking again in spinal cord injury. One autonomic condition after spinal cord injury is orthostatic hypotension, where blood pressure dramatically declines when patients assume the upright posture. Orthostatic hypotension is associated with all-cause mortality and cardiovascular incidents as well as fatigue and cognitive dysfunction, and it almost certainly contributes to an elevated risk of heart disease and stroke in people with spinal cord injury. In addition, autonomic dysfunction leads to bladder, bowel, sexual dysfunctions, which are major contributors to reduced quality and quantity of life. Unfortunately, the available options for treating this condition, are primarily limited to pharmacological options, which are not effective and are associated with various side effects. It has been recently demonstrated that spinal cord stimulation can modulate autonomic circuits and improve autonomic function in people living with spinal cord injury. Neuroanatomically, the thoracolumbar sympathetic pathways are the primary spinal cord segments involved in blood pressure control. Recently, a pilot study has been published demonstrating that transcutaneous spinal cord stimulation of thoracolumbar afferents can improve cardiovascular function. However, some studies have shown that lumbosacral transcutaneous spinal cord stimulation can also elicit positive cardiovascular effects. Therefore, there is no consensus on the optimal strategy in order to deliver transcutaneous spinal cord stimulation to improve the function of the autonomic system, and it may be that lumbosacral (i.e. the stimulation site being used most commonly for restoring leg function is sufficient). Another key knowledge gap in terms of transcutaneous spinal cord stimulation is whether or not the current is directly or indirectly activating these spinal circuits. Last but not least, the effects of epidural spinal cord stimulation on the function of cardiovascular, bladder, bowel and sexual system in spinal cord injury have been investigated in no study yet. AIMS AND HYPOTHESES: Aim 1. To examine the effects of short-term (one session) transcutaneous spinal cord stimulation on the frequency and severity of episodes of orthostatic hypotension/autonomic dysfunction, and bladder, bowel, and sexual functions. These effects will be compared at two sites of stimulation. Hypothesis 1.1: Short-term transcutaneous mid-thoracic cord stimulation will mitigate the severity and frequency of orthostatic hypotension/autonomic dysfunction. Hypothesis 1.2: Lumbosacral transcutaneous spinal cord stimulation will improve bladder, bowel, and sexual functions. Aim 2. To examine the effects of long-term (one month) transcutaneous spinal cord stimulation on the severity and frequency of orthostatic hypotension/autonomic dysfunction. Hypothesis 2.1: Long-term stimulation of the mid-thoracic cord will result in sustained improvements in mitigated severity and frequency of orthostatic hypotension/autonomic dysfunction that is not dependent on active stimulation. Hypothesis 2.2: Long-term lumbosacral transcutaneous spinal cord stimulation will result in sustained improvements in bowel, bladder, and sexual function that is not dependent on active stimulation. Aim 3: To examine the effects of short-term (one session) epidural spinal cord stimulation on the severity and frequency of orthostatic hypotension/autonomic dysfunction, and bladder, bowel, and sexual functions. Hypothesis 3.1: Epidural spinal cord stimulation will mitigate the severity and frequency of orthostatic hypotension/autonomic dysfunction and improve bladder, bowel, and sexual function. Hypothesis 3.3: There is no significant difference between immediate effects of lumbosacral transcutaneous spinal cord stimulation and epidural spinal cord stimulation on bladder, bowel, and sexual function. For aim 1, 14 participants with spinal cord injury and no implanted electrodes on the spinal cord will be recruited. Participants will randomly receive one-hour stimulation under each of the two stimulation conditions in a crossover manner: Mid-thoracic and Lumbosacral. For aim 2, 28 individuals with spinal cord injury and no implanted electrode will be pseudo-randomized (1:1) to one of two stimulation sites. Participants will receive one-hour stimulation, five sessions per week for four weeks. Cardiovascular and neurological outcomes will be measured before the first stimulation session and after the last stimulation session. For aim 3, 4 participants with spinal cord injury with implanted electrodes on the spinal cord will be recruited to study the immediate effects of invasive epidural spinal cord stimulation. All outcomes will be measured in two positions: a) Supine, b) ~ 70° upright tilt-test. Additionally, bowel, bladder, and sexual functions in project 2 will be assessed weekly.
The purpose of this study is to determine whether Fipamezole is effective in the treatment of orthostatic hypotension and related symptoms in multiple system atrophy and Parkinson's disease.
