Filter by:This is a placebo-controlled study evaluating the effects of rosiglitazone on functional brain activity and cognition in patients with mild to moderate Alzheimer's Disease (AD).
The purpose of this study is to evaluate the safety and efficacy of galantamine (a drug for treating dementia) compared to placebo in the treatment of patients with dementia related to cerebrovascular disease (vascular dementia) or dementia related to Alzheimer's disease with cerebrovascular disease ("mixed" dementia).
The purpose of this study is to determine the safety and efficacy of escitalopram (Lexapro) using 10 or 20 mg daily in patients with Alzheimer's disease who are also experiencing agitation.
The specific aims of this study are to: 1. Test the immediate effectiveness of the intervention to reduce caregiver upset with targeted disruptive behaviors (primary outcome). Hypothesis: Caregivers in the intervention group will report less upset with target behaviors at 4-months in comparison to caregivers in the control group. 2. Test the immediate effectiveness of the intervention to reduce caregiver burden (secondary outcome). Hypothesis: Caregivers in the intervention group will report less burden at 4-months in comparison to caregivers in the control group. 3. Test the immediate effectiveness of the intervention to reduce the frequency of occurrence of targeted disruptive behaviors in persons with dementia (secondary outcome). Hypothesis: Caregivers in the intervention group will report a decrease in the frequency of occurrence of targeted behaviors at 4-months in comparison to caregivers in the control group. 4. Test the maintenance effect of intervention at 6-months on caregiver upset and burden and targeted disruptive behaviors. Hypothesis: Compared to usual care, caregivers in intervention will maintain reduced upset and burden and report less occurrences of targeted behaviors from 4 to 6-months. 5. Assess the cost of the intervention and its cost effectiveness. We have also received funding to conduct a supplementary study to evaluate the effect of the nurse intervention on behavior reduction and caregiver distress. The specific aims of this supplementary study arm are to: 1) describe the prevalence and type of medical conditions among control group participants who receive the nurse intervention, 2) describe for those with a detected medical condition/problem, the number of caregivers who follow-up with physicians and the type of physician follow-up/treatment that occurs; 3) evaluate whether control group participants who receive the nurse intervention report reduced disruptive behaviors and caregiver upset at 6 weeks (pre-post comparison); and 4) for control group participants who receive the nurse intervention, compare the level of disruptive behaviors and caregiver upset 4 months from entry into this study arm with the results in the Project ACT experimental group (who received the multi-component intervention).
Specific Aims 1. Establish a preliminary effect size for the impact of the intervention on depressive affect and agitated behaviors in persons with dementia in 4 months 2. Evaluate acceptance of and engagement in activities in persons with dementia 3. Establish a preliminary effect size for the impact of the intervention on caregiver burden, depressive symptoms, and mastery at 4 months. 4. Evaluate caregiver skills acquisition, acceptance of and compliance to intervention techniques.
This study tests the effectiveness of an in-home intervention to reduce upset and burden among family caregivers, and decrease nursing home placement. The main hypothesis that will be tested is that compared to control group, subjects, experimental group participants will have enhanced well-being and fewer nursing home placements.
The purpose of this study is to determine in a 12-week treatment study if MEM 1003 is a safe and effective treatment for patients with mild to moderate Alzheimer's disease.
This study will develop a treatment program to reduce mood and behavior problems in assisted living residents who have dementia.
The aim of the proposed study is to determine if the NMDA receptor antagonist memantine has a neuroprotective effect on magnetic resonance spectroscopic imaging (MRS) measures of brain NAA and magnetic resonance imaging (MRI) volumetric measures of hippocampal volume. In secondary analyses, we will determine if measures of clinical stabilization produced by memantine in the treatment of Alzheimer's disease (AD) parallels stabilization of MRS measures of brain NAA and MRI volumetric measures of hippocampal volume.
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.
