Active clinical trials for "Alzheimer 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 purpose of this study is to evaluate the long-term efficacy and safety of galantamine in patients with Alzheimer's disease.

Memory loss and difficulties with thinking associated with Alzheimer's disease (AD) may be due to a deficiency in the brain of a fatty acid named DHA. The aim of this trial is to see if dietary supplementation with a preparation, rich in DHA, will halt cognitive impairment in AD patients

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 this study is to develop procedures for testing the effectiveness of curcumin on slowing Alzheimer's disease (AD) progression.

Objectives: The objective of this study will be to determine the safety, tolerability, drug blood levels, and efficacy of each of three doses of NS 2330 (Tesofensine) given once daily compared with placebo in patients with mild to moderate Dementia of the Alzheimer's Type.

The purpose of this study is determine the safety, tolerability, and efficacy of 3 doses of lecozotan SR in patients with mild to moderate Alzheimer's Disease over 12 weeks.

The purpose of this study is to evaluate the safety, tolerability and effectiveness of tricaprilin administered once a day for ninety days in subjects with mild to moderate, probable Alzheimer's disease.
