Filter by:The goal of this clinical trial is to learn about and describe how pianistic training influences the development of Alzheimer's disease. The key question is: Can pianistic practice influence the development of Alzheimer's disease? Participants will receive piano lessons for 4 weeks (20 sessions) and we will evaluate the evolution of the different parameters described by the tests carried out.
The goal of this observational study is to learn about current practices for the acute neuropsychiatric management of older adults during emergency department (ED) visits. Researchers will compare current standard of care practices with implemented guideline practice to see if standardized medication guidelines help reduce the usage of antipsychotics and/or benzodiazepines during acute presentations. The main questions this study aims to answer are: - How many older adults are receiving antipsychotics or benzodiazepines during emergency department visits? - Why are older adults receiving antipsychotics or benzodiazepines during emergency department visits? - How many older adults who receive antipsychotics or benzodiazepines during emergency department visits have an underlying cognitive or movement disorder? - What effects does administration of antipsychotics or benzodiazepines during emergency department visits have on patient outcomes in older adults and adults with neurocognitive disorders? - Does implementation of standardized medication guidelines help reduce the usage of antipsychotics and/or benzodiazepines during acute presentations?
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.
Dementia with Lewy body disease (DLB) is the second leading cause of degenerative cognitive disorder after Alzheimer's disease (AD). Its variable clinical expression makes diagnosis difficult. To date, there is no validated DLB diagnostic biomarker, despite several biomarkers in development (EEG, MRI, biology). Studies have shown that an improvement in diagnostic performance could be obtained by combining different modalities biomarkers using machine learning. The aim of this research is to identify the best combination of multimodal biomarkers for the diagnosis of DLB (EEG, MRI, biology, cognitive scores), using a machine learning approach applied to a clinical cohort.
It is now established that disturbances in social cognition are frequent in neurology and that they contribute to the development of social conduct disorders. Their assessment is therefore essential, particularly in order to propose early and adapted care. However, this assessment remains limited today. A new serious game-type test, REALSoCog, has been developed to address the shortcomings of current tools and to highlight disturbances in social behaviors. The latter are not always observed in consultation although they are often reported by caregivers. The objective of this research is therefore to validate the REALSoCog task in a pathological population (currently being standardized in the general population: CER-U, IRB N°: 00012020-115). The clinical interest of this task will be tested with a group of patients suffering from a neurodegenerative disease (Alzheimer's disease (AD), dementia with Lewy bodies (DCL), fronto-temporal lobar degeneration (FTD)) in order to assess its sensitivity and specificity in the detection of social-cognitive disturbances, and in particular in terms of social behaviors (detection of social behavioral disorders reported in daily life). The objective is also to document the socio-cognitive profiles in the mentioned diseases thanks to a more ecological test, and to better understand the links between socio-cognitive processes on the one hand, and individual characteristics on the other hand (e.g. mood and social participation).
A randomized controlled clinical study was conducted in the xuanwu hospital Single Center of Capital Medical University to preliminarily explore the efficacy and safety of transcranial focused low-intensity ultrasound stimulation in the treatment of dementia with Lewy bodies in the early stage, to clarify the effective mechanism and form an effective clinical treatment plan.
Dementia is associated with a variety of neurovascular and neurometabolic abnormalities. Traditional imaging techniques used to investigate such abnormalities, such as Positron Emission Tomography and functional Magnetic Resonance Imaging, are not always well tolerated, have expensive start up and running costs, and are limited with regards to the types of experiments that can be performed as they can be highly sensitive to movement, are noisy, and have physical restrictions. Near-infrared spectroscopy (NIRS) is a non-invasive neuroimaging technique which uses light in the near-infrared spectrum to detect relative changes in concentration of oxygenated and deoxygenated haemoglobin, and the oxidation state of Cytochrome C Oxidase. As such, NIRS can provide measures of brain oxygenation and metabolism. NIRS is less sensitive to movement, is well tolerated and has few contraindications. It is thus a promising candidate for use in clinics or in peoples' homes for monitoring dementia. In the present study, the investigators aim to use both dual-wavelength and broadband NIRS in a range of dementia subtypes, including Alzheimer's Disease and Dementia with Lewy Bodies, and severities, including Mild Cognitive Impairment, to identify how brain oxygenation and metabolism is altered in dementia and across various clinical subgroups. The investigators also aim to determine the relationship between brain oxygenation and metabolism in dementia, and use machine learning approaches to identify optical biomarkers for dementia.
In this study, the investigators implement FDG-PET imaging for clients in the Geriatric Psychiatry department at The Royal Ottawa Hospital (ROH) and evaluate the impact of this advanced imaging technique on client care. This study is intended to provide supporting evidence for the continued use of FDG-PET imaging at the ROH BIC as a diagnostic support for the differential diagnosis of unclear dementia.
The investigators aim to study the effects of a 24-week remote-based resistance exercise training program on cardiovascular disease risk factors, cognitive function, and quality of life in older adults living with mild cognitive impairment or Alzheimer's Disease and/or a related dementia. Data for this study will be collected at the beginning, middle, and end of the resistance training program. Participants of this study will receive a baseline health-fitness assessment at the beginning of the study. Measurements of resting blood pressure, fasting blood glucose and lipids, waist and hip circumferences, height and weight, cognitive function and quality of life will be collected at the health-fitness assessment. Participants will then receive supervised remote-based resistance exercise training with Therabands, 3 days per week for 12 weeks before receiving a second 12-week health-fitness assessment in the middle of the intervention. Participants will then receive 12 additional weeks of supervised remote-based resistance exercise training with Therabands, 3 days per week for 12 weeks before receiving a third 24-week health fitness assessment at the end of the study.
