Filter by:The goal of this observational study is to investigate the prevalence of Neurological Soft Signs (NSS) in various categories of dementia patients compared to matched controls. The main questions it aims to answer are: - Does the prevalence of NSS significantly differ among patients with neurodegenerative dementias compared to controls? - Are NSS associated with neuropsychiatric alterations in dementia patients? - Do NSS correlate with cognitive screening tools? - Do NSS increase over time in patients with neurodegenerative dementias? Participants will undergo assessments including: - Evaluation of NSS using the Heidelberg scale - Neuropsychiatric assessments - Cognitive screening using the Mini-Mental State Examination (MMSE) and Frontal Assessment Battery (FAB) Researchers will compare dementia groups (Alzheimer's disease, Frontotemporal dementia, Corticobasal syndrome and Lewy body dementia) to controls to determine differences in NSS prevalence. Additionally, associations between NSS and neuropsychiatric symptoms, as well as cognitive performance, will be explored.
The temporal sequence of microglial activation, changes in functional and structural connectivity and the progression of neurocognitive deficits has not been conclusively clarified. To date, there have been no studies of the topographical and pathogenetic relationship between microglial activation and network degeneration. The main aim of the present study is to investigate the relationships between functional, structural MRI connectivity and microglial activation at different stages of AD in a multimodal approach. Genetic predisposition and biomarkers in blood and cerebrospinal fluid will also be taken into account in order to close the explanatory gap in pathogenesis between the known molecular pathological changes and their effects at system level in an integrative approach.
In this retrospective register study, clinically classified individuals with neurodegenerative disease from the years 2010-2021 will be verified from the clinical records from KUH and Oulu University Hospital (OUH). Based on the Finnish social security number, these individuals will be linked to the the national registers of Statistics Finland and Finnish Social and Health Data Permit Authority Findata including incomes, sociodemographic factors, education, occupation, criminal records as well as to the national registers including the bought pharmaceuticals, comorbidities and causes of death. For each study case, 10 randomly selected control cases, matched with age, sex and geographical area, will be used. The aim of the study is to examine: - 1) The prevalence of criminal and other disruptive behaviour in groups of different neurodegenerative diseases prior to and after the diagnosis - 2) Changes in employment, residency,income, and marital status prior to and after the neurodegenerative disease diagnosis - 3) Hospital diagnoses and reimbursable drugs prior to and after the diagnosis - 4) Causes of death in patients with neurodegenerative disease to study excess mortality of the patients
The New York Stem Cell Foundation (NYSCF) Research Institute is performing this research to accelerate diverse disease research using cells from the body (such as skin or blood cells) to make stem cells and other types of cells, conduct research on the samples, perform genetic testing, and store the samples for future use. Through this research, researchers hope to identify future treatments or even cures for the major diseases of our time.
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.
Corticobasal syndrome (CBS) is a rapidly progressive neurodegenerative disorder with an average survival time of about 6-8 years after the first clinical manifestation. No potent symptomatic treatment is currently available. A disease-modifying therapy does not exist either. Neuroinflammation is key to the pathogenesis in neurodegenerative diseases with Tau- and/or AD-pathology. There is strong evidence that phenylbutyrate can modulate microglial function by enhancing their phagocytic activity, most likely by epigenetic mechanisms. So the main goal of this clinical trial is to study a potential disease-modifying effect of treatment with glycerol phenylbutyrate (GPB), which is a prodrug of phenylbutyric acid, for 26 weeks assessed by the levels of the biomarker neurofilament light chain (NfL) indicating disease progression in CBS. Given the aggressive nature of CBS, it is feasible to study effects of GPB on plasma NfL levels.
The primary objective of this study is to enroll an observational cohort of approximately 60 patients with PSP over the course of 24 months using a multicenter study design and to follow each of them for 12 months. The secondary objective of this study is to develop a robust solution for multi-modal remote monitoring of motor symptoms and function in PSP that can be applied to other Frontotemporal lobar degeneration (FTLD) syndromes.
The goal of this pilot trial is to test whether scrambler therapy (ST) is an effective treatment for neuropathic pain in patients with corticobasal syndrome (CBS). The main question it aims to answer is: Will ST reduce pain scores by at least 33% at one month in this pilot trial, justifying further multi-center trials? Participants will: - be randomly assigned treatment from either transcutaneous electrical nerve stimulation (TENS) or ST for pain initially (eventually all patients will receive ST). - have superficial electrocardiogram (ECG) electrodes placed on the dermatomes involved with pain - obtain treatment lasting 30-40 minutes or until pain relief is obtained Researchers will compare patient's response to pain relief with TENS and ST to determine if ST is an effective treatment for central neuropathic pain.
Study Rationale: No accurate tests currently exist to diagnose Parkinson's disease (PD) and the conditions which mimic it (atypical parkinsonism) at a very early stage. Similarly there are no accurate ways to track how these diseases progress in a very precise manner. Recording eye movements and pupils may be a very sensitive way of doing this and may contain important information about a patient's diagnosis and their cognitive and motor function. Hypothesis: We hypothesize that measuring eye movements and pupil changes while people watch short video clips will differentiate PD and atypical parkinsonism at an early stage. We hypothesize that eye movements and pupil changes will be able to track how a person's disease changes over time and could even predict their disease course from the start. Before we can do this, we need to be able to accurately differentiate between PD and atypical parkinsonism and see how eye movements vary among people with the same disease. Study Design: We will ask a large number of people with PD and atypical parkinsonism to watch very brief video clips while we record eye movements and pupil responses. This is like changing the television channel every few seconds and observing what happens to a person's eyes as they search the new clip. We will compare these results between different disease groups and correlate them with clinical features of PD and atypical parkinsonism. Impact on Diagnosis/Treatment of Parkinson's disease: This may have enormous impact in the assessment of people with PD. It may become an important diagnostic tool, a prognostic marker at the early stage of disease, as well as providing the ability to track disease progression in clinical trials. Next Steps for Development: Once we can demonstrate that eye tracking can differentiate these conditions, we will follow a large number of patients to see how their eye movements and pupils change over time with their disease. If this is a reliable way to track disease it could be used to measure disease progression in these conditions and response to treatment.
