Active clinical trials for "Alzheimer Disease"

The purpose of the study is to determine the safety, tolerability, and efficacy of 3 doses of lecozotan in combination with a cholinesterase inhibitor in patients with mild to moderate Alzheimer's disease (AD).

The purpose of this study is to determine whether Tanakan® is effective at slowing the progression from memory complaint to dementia of Alzheimer's type.

Background: Partners in Dementia Care (PDC) is a care coordination and support service intervention for veterans with dementia and their family caregivers, delivered through partnerships between VA medical centers and local Alzheimer's Association Chapters. PDC was designed to be a feasible and practical intervention to integrate health, community, and support services. PDC has a standardized protocol for care coordination and support services, including guidelines for care plan assessment, care plan development and implementation, ongoing monitoring, and reassessment. It also offers a structured training curriculum for providers and an operations manual for uniform implementation. Objectives: The primary objective was to test the impact of PDC on outcomes for veterans with dementia and family caregivers. Two specific research objectives and corresponding hypotheses were addressed: 1. To test the impact of PDC on three categories of outcomes: psychosocial well-being outcomes (patient and caregiver effects); health care service use (patient effects only); and health care cost (patient effects only). HI:PDC, compared to usual care, will improve psychosocial well-being for patients with dementia and their caregivers. H2:PDC, compared to usual care, will reduce health care service use for patients with dementia. H3:PDC is preferred to usual care based on cost-benefit analyses. H4:The PDC intervention will be more effective in improving psychosocial well-being and reducing health care service use for patients and caregivers dealing with more severe patient impairment (e.g., cognitive status, functional status, and level of problem behaviors). 2. To evaluate the impact of PDC on role and intra-psychic strains caused by dementia and its care (patient and caregiver effects). H5a:PDC, compared to usual care, will decrease patient role and intra-psychic strain. H5b:PDC, compared to usual care, will decrease caregiver role and intra-psychic strain. H6:The PDC intervention will be more effective in decreasing role and intra-psychic strains for patients and caregivers dealing with more severe patient impairment (e.g., cognitive status, functional status, and level of problem behaviors).

The purpose of this study is to evaluate the efficacy and safety of two fixed doses (16mg/day and 24mg/day) of galantamine (a drug for treating dementia) versus placebo for the treatment of patients with Alzheimer's disease, and to investigate the dose-response.

Rosiglitazone (RSG) has been tested in clinical studies and is approved by the FDA as a treatment for type II diabetes mellitus, a disease that occurs when the body is unable to effectively use glucose. RSG XR, the investigational drug used in this study, is an extended-release form of RSG. This study tests whether RSG XR safely provides clinical benefit to people with mild to moderate Alzheimer's disease (AD) when combined with one of the currently approved AD medications, Aricept®, Razadyne® or Exelon®. RSG XR is a new approach to AD therapy and this study tests a new way to treat AD by testing whether one's genetic makeup affects the response to the study drug. Clinical data suggesting that RSG may benefit AD patients was first seen in a small study performed at the University of Washington and then from a larger GSK study conducted in Europe and New Zealand. In the first study, subjects receiving RSG once daily for 6 months scored significantly better on 3 tests of memory and thought than those who did not receive RSG. In the GSK study, those that appeared to benefit most from treatment with RSG XR had a specific genetic pattern. They did not have the gene that caused them to produce the protein apolipoprotein E e4 (APOE e4). Subjects who have the APOE e4 gene may have two copies, one from each parent, or they may have only one APOE e4 gene meaning that they inherited either the APOE e2 or APOE e3 version of the gene, instead of APOE e4, from one of their parents. Subjects with one copy of the APOE e4 gene remained at their same level of thinking ability while those with two copies of the APOE e4 gene, continued to worsen during the 6-month treatment. The current study will more directly test the effectiveness or RSG XR on people who either have or lack the APOE e4 gene.

The purpose of this study is to find out if SB-742457 is a safe treatment and what effects it has on the symptoms of mild to moderate Alzheimer's Disease. SB-742457 is a new treatment which is thought to increase the levels of certain chemicals in the brain that are often decreased in patients with Alzheimer's Disease.

The purpose of the study is to compare the safety and efficacy of risperidone (an antipsychotic medication) to that of placebo in the treatment of behavioral disturbances associated with dementia.

Apathy, or lack of motivation, affects up to 80% of Alzheimer's disease (AD) patients. These amotivational symptoms increase patient reliance on caregivers, increase caregiver burden and distress, and increase the risk of patient institutionalization. Only 50% of patients with apathy respond to current treatment with cholinesterase inhibitors. The mechanism of apathy in AD is unknown hampering rational treatment. Our proposed pilot study will provide initial data required to develop an amphetamine challenge paradigm to probe the brain reward system. These results will be used to develop a larger study evaluating the role of the brain reward system in apathy in AD and link this information with pharmacologic treatment. AD is a complex neurobiological illness that needs to be understood at several levels to optimize treatment. At a neurochemical level, one has to identify the neurotransmitter abnormalities that accompany the clinical symptoms. The neurochemical level of analysis provides the link between pathology and symptoms and, for now, is the only avenue for biological therapies. Next, one has to translate knowledge of neurochemical abnormalities to practical treatments for the symptoms of AD. This pilot will allow us to develop a study that can address both of these goals. Furthermore, the larger study will further define the emerging concept of apathy as a syndrome and has broader implications for apathy in many other neuropsychiatric diseases.

This is a clinical trial to test the effectiveness of current guideline for the care of older adults with Alzheimer's disease. The study focuses on the primary care setting using a nurse care manager to facilitate guideline-level care. We are hypothesizing that patients who receive guideline-level care will have fewer behavioral problems than those who receive the usual care provided in primary care settings

The primary objective of this study is to evaluate the effects of computer-based training program ("HiFi-AD") on the memory and cognitive abilities of individuals diagnosed with mild Alzheimer's Disease (AD).
