Active clinical trials for "Alzheimer Disease"

This study is assesses the feasibility and acceptability of telephone-delivered mindfulness training designed to alleviate caregiver burden for African-American rural caregivers of individuals with moderate to severe dementia, as defined by the caregiver. The study utilizes a single-group, uncontrolled design to test the feasibility and acceptability of the intervention for the target population.

The aim of the project is to evaluate the efficacy of a web-based psycho-educational programme designed to support informal caregivers of patients with Alzheimer's disease (AD).This program focuses on information about the illness, her progression, how to prevent psychological strain using anticipation and relaxation techniques and providing a virtual space (forum) to discuss with other caregivers.

The primary objective is to assess the safety and tolerability of a single oral dose of BMS-708163 in healthy young male subjects and in elderly male and female subjects.

The purpose of the study is to evaluate the pharmacokinetics, safety and tolerability of BMS-708163 administered as single and multiple doses in Chinese subjects

This study will examine the brain metabolic effects of AC-1202 (Axona®), a medical food for Alzheimer's disease. Subjects who meet entry criteria will undergo H215O positron emission tomography prior to and 90 minutes after consumption of Axona® at baseline and then again after 45 days of treatment. Cognitive testing will also be conducted at baseline and day 45.

Alzheimer's disease (AD) and related forms of dementia currently affect over 400,000 individuals in Canada and the numbers of community dwelling older adults with AD is rapidly growing. AD is associated with over $15 billion annually in care costs. Most individuals with AD are under the care of primary care providers (PCPs) including family physicians and primary care nurses. The evaluation and management of AD is challenging for PCPs and the quality of care provided to older adults with AD by PCP could be improved which would optimize outcomes for this vulnerable population. Provision of quality care to older adults with AD involves implementation of best practices as outlined in guidelines such as the Canadian Consensus Conference Guidelines on the Diagnosis and Treatment of Dementia. Utilizing a group of dementia researchers, PCPs, other knowledge users, and individuals affected by AD, this project will develop practical, clinically relevant resources for primary care physicians and nurses to aid in the evaluation of older adults with AD. A knowledge tool, the Primary Care - Dementia Assessment and Treatment Algorithm (DATA Tool) will be introduced into several primary care settings in Ontario using educational sessions with PCP with additional support from internet resource and a dementia care manager. The quality of dementia care provided to older adults newly diagnosed with AD will be assessed in the three years preceding the intervention compared to the year following the implementation. This project will also describe the process of knowledge exchange with PCPs, including potential barriers and facilitators of knowledge uptake and examine if the care provided during the intervention was patient-centred through interviews with patients and caregivers. Research Objectives: Develop knowledge tools to facilitate assessment and treatment of AD by PCPs based on best evidence; Transfer these knowledge tools into a variety of primary care settings in Ontario; and, Evaluate the effects of this intervention on dementia quality of care, PCP application of knowledge, and the patient-centeredness of care.

Specific Aims Establish a preliminary effect size for the impact of the intervention on depressive affect and agitated behaviors in persons with dementia in 4 months Evaluate acceptance of and engagement in activities in persons with dementia Establish a preliminary effect size for the impact of the intervention on caregiver burden, depressive symptoms, and mastery at 4 months. Evaluate caregiver skills acquisition, acceptance of and compliance to intervention techniques.

Recent data show that marked cell damage precedes the clinical manifestation of Alzheimer's disease (AD). Hence, targeting populations at risk with pharmacological interventions is a possible strategy to lessen the burden of the disease. Cognitively normal individuals with subjective memory complaints (SMC) manifest biological characteristics consistent with early AD and are at risk for future cognitive decline. Family history of AD also constitutes a risk. In a previous study the investigators showed that memantine slows down the accumulation of phosphorylated tau in normal SMC subjects. Using a multivoxel high field MR spectroscopy (MRS) technique, the investigators also demonstrated that memantine decreased hippocampal glutamate. Both these findings may be consistent with the drug's anti-excitotoxic activity. In this new project the investigators propose to treat a sample of 12 presymptomatic individuals at risk (SMC and family history of AD) with memantine. This will be a double blind, placebo controlled study with a control group (12 non-treated subjects). The investigators will determine whether the effects of memantine as assessed by cognitive performance and MRS are present after 4 months of treatment and persist 2 months after discontinuation. MRS will be used to evaluate the effect of memantine on levels of the neurotransmitter glutamate and neuronal viability marker N-acetylaspartate (NAA) in the hippocampus. The investigators will test the following hypotheses: In subjects with SMC, memantine has modifying effects on brain biochemistry as reflected in MRS reductions in glutamate (reduced excitotoxicity) and increases in NAA (neuronal integrity). The effects of the drug persist (as a marker of sustained neuroprotection) and can be measured 2 months after discontinuation of the treatment.

To evaluate the safety, tolerability, multiple dose plasma pharmacokinetics (PK) of LNK-754 in male and female elderly volunteers after dosing with LNK-754 for 7 days and in subjects with mild Alzheimer's Disease after dosing with LNK-754 for 28 days.

The purpose of this study is to find out if the plasma concentration of donepezil is changed when BMS-708163 is administered at the same time
