Striatum and Hippocampus on Different Time Scales
Time processing is fundamental to survival and goal reaching in humans. Different time scales (seconds, minutes, and beyond) are processed through specific cognitive processes involving different neural representations. It is generally agreed that time scale in seconds-to-minutes range named "interval timing" would be anatomically linked to the striatum. Indeed, it …
Cardiac-Control Affecting Learning Through Mindfulness (CALM)
Some types of meditation lead heart rate to become more steady as breathing quiets whereas others lead to large heart rate swings up and down (oscillations) as breathing becomes deeper and slower. The current study is designed to investigate how daily mindfulness practice with heart rate biofeedback during breathing in …
Learning Skills Together Family Caregiver Complex Intervention
Learning Skills Together (LST) is a 6-week psychoeducational intervention focused on complex care (nursing) tasks completed by family caregivers to persons living with Alzheimer's Disease and related dementias. This study aims to test the efficacy of LST at reducing caregiver depression and negative appraisal of behavioral symptoms of dementia by …
Analysis of 18F-XTR006 PET Imaging in Cognitively Normal Subjects, and Patients With MCI and AD
The goal of this clinical trial is to evaluate the efficacy and safety of XTR006 injection PET visual reading in detecting brain neurofibrillary tangles (NFTs) in elderly subjects with Mild Cognitive Impairment (MCI), Alzheimer's Disease (AD), and cognitively normal individuals. The main question it aims to answer is: • What …
First-in-Human Evaluation of an Astrocytic Glutamate Transporter (EAAT2) PET Tracer in Dementia
This is a first in human study that will assess the safety and diagnostic performance of [18F]RP-115 (fluorine-18 labeled RP115), a positron emission tomography (PET) agent. This agent has the potential to identify the early changes that occur in the brains of patients with Alzheimer's disease (AD) and frontotemporal dementia …
Nabilone for Agitation Blinded Intervention Trial
This study will look at whether nabilone is an effective treatment for agitation in Alzheimer's disease (AD) patients. Agitation is highly prevalent in patients with AD and is one of the most distressing and challenging-to-treat symptoms. Agitation is associated with faster progression to institutionalization, increased caregiver burden, poorer quality of …
Efficacy, Safety and Response Predictors of Adjuvant Astragalus for Cognition in Orthostatic Hypotension
Background: This pragmatic clinical trial aims to determine the efficacy and safety of add-on Astragalus for cognition and non- cognition in patients with of mild to moderate Alzheimer's disease complicated with orthostatic hypotension in orthostatic hypotension, elucidate the underlying mechanisms, identify related response predictors, and explore effective drug components. Methods: …
The Effects of Specific tDCS on Cognition in MCI
INTRODUCTION Mild cognitive impairment (MCI) is a critical transitional stage in dementia related disorders. Dorsolateral prefrontal cortex (DLPFC), and the lateral parietal (LPC) cortex are subjected to neuropathological changes in MCI. Parietal memory network (PMN) integrity alterations and default mode network (DMN) alterations also occur in MCI. Transcranial direct current …
Study to Evaluate the Efficacy, Safety, and Tolerability of BMS-986368, for the Treatment of Agitation in Participants With Alzheimer's Disease
This is a study to evaluate the efficacy, safety, and tolerability of BMS-986368, a FAAH/MAGL inhibitor, for the treatment of agitation in participants with Alzheimer's Disease.
An Exploratory Study to Confirm Efficacy of Modified Deep Cervical Lymphovenous Anastomosis (LVA) in Alzheimer's Disease/ Parkinson's Disease
Alzheimer's disease (AD) and Parkinson's disease (PD) are characterized by pathological protein accumulation in the brain-Aβ/tau in AD and α-synuclein in PD. Recent studies have indicated that age-related lymphatic vessel atrophy compromises the metabolic clearance capacity of meningeal lymphatic vessels, potentially disrupting the equilibrium between production and clearance of Aβ/α-synuclein, …
