Filter by:This phase IIIb study is intended to implement a consistent treatment way for switching to Exelon transdermal patch from oral formulation of rivastigmine to stress the importance of (1) advantages of transdermal patch over conventional oral therapies: smooth drug delivery with reduced side effects;(2) encourage treatment compliance in the Alzheimer's dementia setting. This study is a single-arm, treatment-switched design. Eligible patients, who are under Exelon capsule 3 mg b.i.d. treatment for 4 weeks before Visit 2, will be recruited, followed by treatment switch from oral capsule to patch for 48 weeks maintenance treatment. During the maintenance period, the treatment will be initiated with Exelon Patch 4.6 mg/24 hours (Exelon Patch 5 cm^2) for the first 24 weeks and the dose will be escalated to Exelon Patch 9.5 mg/24 hours (Exelon Patch 10 cm^2) for another 24 weeks if well tolerated. Visits to assess safety are scheduled at baseline, 3 days, 1 week and 2 weeks after the first treatment switch, every 4 weeks until Week 40, and at the end of study (Week 52). The assessment to address the primary objective will focus on the safety of treatment switching (Week 0~28); however the safety assessment will be performed during the whole study period.
The objectives of the study are to evaluate the safety, tolerability and efficacy of AVP-923 compared to placebo, for the treatment of symptoms of agitation in participants with Alzheimer's Disease (AD).
It is now acknowledged that Alzheimer's disease is characterized by a long period of pathophysiological change. Developing new strategies to achieve diagnoses as early as possible has become a major goal for therapies aimed at slowing the progression of this disease. While diagnoses currently rely principally on clinical neuropsychology, the typical diagnostic criteria of NINCDS-ADRDA are inapplicable in the early stage of the disease. The goal of our project is to identify very early imaging markers for Alzheimer's disease among patients with no report of cognitive difficulties. In order to achieve this goal, we propose a longitudinal study in an elderly population cohort.
The aim of this study is to determine whether saccadic eye movement recording may help in the discrimination between Lewy body dementia and Alzheimer disease, in the early stages of the disease. Study type: Interventional Study design: Intervention Model: Single group assignment Primary purpose: Diagnostic
The main aim of the present study is to improve our understanding of the role of blood-brain barrier function in dementia of the Alzheimer's type. The investigators hypothesize that microvascular dysfunction - more specifically "cerebral perfusion and blood-brain barrier leakage" - is a determinant of cognitive decline and cortical atrophy in Alzheimer's disease.
Past epidemiological studies have demonstrated that larger social networks, or more frequent social interactions, could have potential protective effects on the incidence of Alzheimer's Disease (AD). However, in those studies, indicators of social interactions were often broad, and included distinct elements that affected cognition and overall health. This project will examine whether conversation-based cognitive stimulation has positive effects on domain-specific cognitive functions among the elderly. Face-to-face communication will be conducted through the use of personal computers, webcams, and user-friendly simple interactive Internet programs to allow participants to have social engagement while staying at their home and also for the cost effective execution of the study.
The main objectives of this study are: - To evaluate the driving capacities in a population of elderly subjects with early stage Alzheimer Disease (AD) in a real-life situation. - Define a typology of the main errors made in this population. - Propose adaptive measures or technological aids that would make it possible for these patients to maintain their ability to drive a car while limiting risk.
Main objective: investigate whether a functional polymorphism of CR1 (length, number of binding sites in C4b C3b, erythrocyte density, rate of soluble CR1 ...) so determined genetic or acquired, is a susceptibility factor for the disease Alzheimer's.
Re-read of brain amyloid scans acquired in previous AV-45 clinical studies by readers trained using updated reading methodology. The scans in this study came from subjects who had Alzheimer's Disease (AD) or Mild Cognitive Impairment (MCI).
The purpose of this study is re-read of brain amyloid positron emission tomography (PET) scans acquired in previous florbetapir F 18 clinical studies by readers trained using updated reading methodology. The scans in this study came from subjects who had an autopsy to reveal the subject's true amyloid status.
