Filter by:The study is designed to inquire whether the presence of periodontitis and different periodontopathogenic bacterial strains are associated with dementia diagnosis and with the degree of cognitive impairment in participants evaluated at a Memory clinic (Minnesmottagning). Specifically, by analyzing cerebrospinal fluid, the investigators intend to clarify whether the alleged mechanisms for Porphyromonas gingivalis in the aetiology of Alzheimer disease (AD) are supported in a Swedish population and whether they are specific for Porphyromonas gingivalis (as compared to other periodontopathogenic bacteria) and Alzheimer type dementia (as compared to other etiological dementia types), respectively.
This trial is a multi-center, double-blind, placebo-controlled, randomized study to evaluate the efficacy and safety of AXS-05 compared to placebo for the treatment of agitation associated with Alzheimer's disease.
The aim of this study is to - detect and assess needs of people with early onset dementia regarding anxiety, stress and sleep - implement a 6 week intervention pilot study in wich weekly (hourly) sessions are implemented in day care settings in order to decrease anxiety, stress and sleep problems in people with early onset dementia
The purpose is to evaluate the biomarker effect, safety, and tolerability of investigational study drugs in participants who are known to have an Alzheimer's disease (AD)-causing mutation. Part 1 will determine if treatment with the study drug prevents or slows the rate of amyloid beta (Aβ) pathological disease accumulation demonstrated by Aβ positron emission tomography (PET) imaging. Part 2 will evaluate the effect of early Aβ plaque reduction/prevention on disease progression by assessing downstream non-Aβ biomarkers of AD (e.g., CSF total tau, p-tau, NfL) compared to an external control group from the DIAN-OBS natural history study and the DIAN-TU-001 placebo-treated participants.
This is a randomized, double-blind, placebo-controlled first-in-human, Phase 1, safety, tolerability, pharmacokinetic (PK) and preliminary exploratory activity study of escalating multiple intravenous (IV) doses of IBC-Ab002 in persons with early Alzheimer's disease. The study will have both Single- and Multiple-Ascending Dose components.
The proposed project is a fully embedded pragmatic trial (R01), following an R61 pilot collaboration with Lutheran Social Service of Minnesota (LSS-MN). For this project: a) the training program for Senior Companions that was developed in the R61 Phase will now be delivered as part of a routine onboarding process provided by LSS-MN to all senior support volunteers in half of their program regions across Minnesota; LSS-MN will offer the PorchLight Project program to all regions and volunteers in the state during the final months of the proposed NIA project, consistent with quality improvement approaches; and b) LSS-MN will administer regular surveys to volunteers, clients, and their proxies (e.g., family caregivers) as part of ongoing tracking and quality improvement efforts. The University of Minnesota investigators will not collect data nor administer training, as these activities will be fully integrated into the workflow of LSS-MN. UNIVERSITY OF MINNESOTA INVOLVEMENT: The University of Minnesota and collaborating investigators outside of LSS-MN will only 1) assist in survey item selection, 2) randomize the LSS-MN regions for the initial phases of the real-world trial for evaluation purposes, 3) analyze the de-identified data shared by LSS-MN, and 4) disseminate the project results in scientific, practice, and policy outlets/contexts.
This is a cross-sectional and longitudinal study to investigate the relationship and central mechanism between type 2 diabetes and cognitive impairment based on the simultaneous EEG-fMRI approach and peripheral neuropathology biomarkers assay.
Background: Sleep disturbances are highly prevalent in ageing population and patients with age-related neurodegenerative diseases, which severely affect cognition and even lead to accumulated amyloid-β (Aβ). At present, non-pharmacological interventions for sleep disturbances in dementia patients are accepted as first line of treatment, of which the evidence from clinical trials is very limited. Encouraging results from recent studies on transcranial direct current stimulation (tDCS) showed moderate positive effects on sleep quality in preclinical Alzheimer's disease (AD). Compared to tDCS, high-definition transcranial alternating current stimulation (HD-tACS) enables the entrainment of neuronal activities with optimized focality through injecting small electric current with a specific frequency and has significant enhancement effects on slow wave activities. Objectives: The investigators aim to 1) investigate and compare the safety, efficacy and sustainability of 40 Hz HD-tACS and HD-tDCS over left dorsolateral prefrontal cortex (DLPFC) in mild neurocognitive disorder due to AD (NCD-AD) patients with sleep disturbances; 2) examine the relationship between the changes in sleep quality, cognitive function and saliva Aβ levels. Methods: Chinese right-handed mild NCD-AD patients with sleep disturbances (aged from 60 to 90 years) will be randomly assigned to a 4-week intervention of either HD-tACS, HD-tDCS, or sham HD-tCS, with 33 participants per arm. Before intervention, structural magnetic resonance imaging (MRI) data is used to construct individual realistic head model. Comprehensive assessments, including sleep quality, cognitive performance and saliva Aβ levels will be conducted at baseline, 4th week, 8th week, 12th week and 24th week. Program adherence and adverse effects will be monitored throughout intervention. Data analysis: The primary outcomes will be the changes in sleep quality and memory performance with modality-driven paradigms (HD-tACS, HD-tDCS, sham HD-tCS), and comparisons of group differences across different time points. Secondary outcomes will be the changes objective sleep pattern, global cognition, saliva Aβ levels and quality of life. Intention-to-treat analysis will be carried out. Changes of efficacy indicators from baseline to each follow up point will be tested with mixed effect model. Significance: This study aims to investigate the feasibility, safety and efficacy of HD-tACS and HD-tDCS over left DLPFC for sleep disturbances and cognitive dysfunction in mild NCD-AD patients. It wills also test the program adherence, tolerability and adverse effects of this innovative neurotechonology. Information will be helpful for in-depth understanding the relationship of "sleep disturbances-amyloid deposition" and guiding the further studies of sleep medicine and neurodegenerative diseases.
The purpose of this study is to assess the efficacy of an oral medication, IGC-AD1 that is a natural THC-based (Tetrahydrocannabinol) formulation, administered in micro doses, twice a day, on symptomatological Agitation, in patients with mild to severe dementia from Alzheimer's.
The overall objective of this study is to compare the overall pattern of [18F]APN-1607 uptake in subjects with MCI, subjects with AD dementia, and healthy subjects.
