Filter by:The primary purpose of this study is to evaluate the safety and the tolerability of NEUROSTEM®-AD (Human Umbilical Cord Blood Derived Mesenchymal Stem Cells) and to assess the maximum tolerated dose (MTD). This study is also to investigate the efficacy of this study drug in patients with dementia of Alzheimer's type.
This investigation is designed to study how the brain functions when it is performing explicit memory tasks, and furthermore how the brain systems supporting performance on these tests change as a function of aging. Implicit memory tasks may be distinguished from explicit memory tests in that explicit memory characterizes the directed or intentional recollection of previously learned information or events. In contrast, implicit (or nonconscious) memory is expressed in the facilitation of performance on some task or judgment on a stimulus owing to a prior presentation of that stimulus, without any necessary conscious awareness of the prior presentation. The investigators propose to use functional Magnetic resonance Imaging (fMRI) to measure brain activity during the performance of carefully designed explicit memory tasks. Comparison of brain activity during the different test conditions will provide information about the brain areas that are involved in mediating specific aspects of performance. Both older and younger individuals will be tested in order to understand age related changes in the brain activity. In order to examine the interactions between participants' differential levels of amyloid burden and their performance on cognitive tasks and fMRI neural activation, the investigators also propose PET imaging of older participants.
To compare the relative bioavailability and pharmacokinetic characteristics of a newly developed donepezil formulation with a conventional formulation in healthy subjects with a single dose, randomized, open-label, 2-sequence -2period crossover study.
The effectiveness of reminiscence for dementia has been claimed as an effective tool, but scientific validation and systematic assessment of this method is needed. Materials and Methods: A randomized controlled trial (RCT) was conducted to search whether a reminiscence program is associated with improvement of quality of life of demented long term care residents. The trial had three arms: interventional, comparison and control. The reminiscence program was modeled within a life-story approach, while comparison group received informal counseling to control for changes in quality of life resulting from social contacts. The Social Engagement Scale (SES) and Self-rated Quality of Life Index (SRQoL) were the outcome measures. The results were examined at baseline (T0), twelve weeks (T1), and 6 months (T2) after intervention. The sample had 135 subjects [intervention group (N=45), comparison group (N=45) and control group (N=45)].
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of E2609 when administered as single doses to healthy adult volunteers and healthy elderly subjects. The study will consist of 2 parts:(1) a single dose in healthy adult volunteers, at doses up to 800 mg or the maximum dose that can be tolerated, (2) a single dose of 50 mg in healthy elderly volunteers.
A Phase II clinical research study to evaluate the efficacy and safety of two different dose levels of an injectable investigational treatment (ACC-001) in subjects with Mild-to-Moderate Alzheimer's disease. ACC-001 (vanutide cridificar) is a beta amyloid fragment attached to a carrier protein. It is intended to help induce an antibody response against beta amyloid and is administered as an intramuscular injection.
The purpose of this study is to compare 23 mg donepezil sustained release (SR) to the currently marketed formulation of 10 mg donepezil immediate release (IR) in patients with severe Alzheimer's disease.
The purpose of this study is to determine whether a comprehensive cognitive-behavioral therapy-based, multi-component treatment programme is effective in the treatment of neuropsychiatric symptoms of patients with mild Alzheimer's dementia.
The underlying goal of this study is to assess [18F]-FMH3 PET imaging as a tool to evaluate the activity of the H3 receptor in the brain of Alzheimer Disease (AD) research participants
Primary Objective: - To demonstrate the efficacy of at least one dose of SAR110894 (H3 receptor antagonist) in comparison to placebo on cognitive performance in patients with mild to moderate Alzheimer's disease (AD) while on stable donepezil therapy Secondary Objectives: - To explore the effect of SAR110894 on functional impairment, global clinical status and behavioral disturbances; - To assess the safety/tolerability of SAR110894; - To assess pharmacokinetic (PK) of SAR110894 and concentrations of donepezil; - To explore caregiver time consumption and distress changes.
