Filter by:The purpose of this study is to evaluate the safety of administration and effects of valproic acid on clusterin expression in cognitively-intact, healthy, elderly subjects. Clusterin mutations have recently been identified as a risk factor for the development of Alzheimer's Disease and changes in clusterin expression are seen in the elderly who develop Alzheimer's disease irrespective of whether they carry these genetic mutations or not. Valproic acid may prevent or reverse these changes. Fourteen subjects with normal memory and thinking will participate in this study. Ten of these subjects will receive valproic acid and 4 will receive a "placebo" capsule with no active medicine. Participants will take study medication or placebo for 28 days and be followed for a total 35 days in this trial.
The purpose of this study is to determine the value of Arterial Spin Labeling (ASL) MRI, a measure of blood flow to the brain, in Mild Cognitive Impairment (MCI) and compare it to existing measures. In particular, the investigators will compare ASL MRI to Positron Emission Tomography (PET/CT), which measures brain metabolism reflecting how well cells in a patient's brain are functioning. In addition, the investigators will assess the relationship of these measures to specific protein levels associated with Alzheimer's Disease in the patient's cerebrospinal fluid (the fluid that surrounds the brain and spinal cord) obtained by lumbar puncture. By comparing the information that is available from these procedures to the patient's performance on cognitive tests, the investigators hope to learn which procedures most accurately reflect and assist in determination of the potential causes of cognitive difficulties that arise with MCI, and thus, which are most useful in the clinical setting. In particular, PET scans have been found to be very useful in diagnosis of MCI and Alzheimer's Disease, but the investigators want to find out if they can get the same, or better, information from an ASL MRI scan, which is less expensive and easier to acquire.
The proposes of this study are 1. To understand the physical activities of patients with cognitive impairment in Taiwan and construct the validity and reliability of the physical activity questionnaire and actigram in this population. 2. To understand the relation between brain structure (brain tractography and resting state functional MRI) and cognitive and physical functions of patients with cognitive impairment, the capability of activity and social engagement (including quality of life). 3. To understand the efficacy of exercise on the brain structure (brain tractography and resting state functional MRI), cognitive and physical functions, the capability of activity and social engagement (including quality of life) of the patients with cognitive impairment. The study aims to establish the data base of physical activity of patients with cognitive impairment in Taiwan. We will also analyze the efficacy of exercise with ICF model on physical function, physical activity and social engagements to provide an optimized design of exercise program for patients with cognitive impairment in the future.
This Phase II, open-label extension (OLE), multicenter study will evaluate the long-term safety and tolerability of crenezumab in participants with mild to moderate Alzheimer's disease who have participated in and completed the treatment period of the Phase II Study ABE4869g (NCT01343966) or ABE4955g (NCT01397578). Participants who received placebo in Study ABE4869g (NCT01343966) or ABE4955g (NCT01397578) will receive crenezumab. Anticipated time on study treatment is 144 weeks.
To evaluate the effects of multiple dose regimens of CHF 5074 administered once per day up to 2 years on potential biomarkers of neurodegeneration in subjects with mild cognitive impairment.
This study will be a single-center, open-label, randomized, 3-treatment crossover study of single oral doses of an API-capsule formulation of E2609 under fasted conditions and a tablet formulation administered under fed and fasted conditions in healthy subjects.
While the cause of AD is still unknown, evidence suggests it develops because of a complex series of events in the brain that occur over time. Two pathways possibly involved in development of AD are inflammation and oxidative stress. Scientists have linked chronic inflammatory events in the brain with the onset and progression of Alzheimer's Disease. Oxidative stress has also been implicated in the pathogenesis of a number of neurological disorders including Alzheimer's Disease. Etanercept (Enbrel®) is an approved drug for the treatment of several forms of arthritis when administered by injection. Some research suggests that etanercept, when administered by injection into the tissues close to the spinal column (perispinally), may modulate certain aspects of the immune system and provide some beneficial effect for people with Alzheimer's disease. Studies suggest that supplementation with specific nutrients may also have a positive effect in support of cognitive function. This study will be conducted at one research office with volunteers who have been diagnosed with mild to moderate Alzheimer's disease. Each qualifying participant will be randomly assigned to receive an etanercept injection plus nutritional supplements for 6 weeks followed by a crossover and a washout period of 4 weeks to then receiving nutritional supplements alone or vice versa for another 6 weeks. Participants will undergo blood and urine safety assessments at the beginning and end of each 6 week treatment period. During 4 of the 6 weekly visits in the treatment period with the injections, you will complete the cognitive tests twice; once before and once 2 hours after the injection. During 4 of the 6 weekly visits in the treatment period without the injections, you will also complete the cognitive tests twice; once before and once 2 hours after being asked to lie down onto a table for 5 minutes. You will be allowed to continue your standard of care for Alzheimer's disease throughout your participation in the study.
The investigators intend to perform exploratory evaluation of the treatment effectiveness and safety of PM012 Tablet of PuriMED Co., Ltd. at 2 doses in Korean patients with mild to moderate dementia of Alzheimer's type. To achieve this, this study aims to compare each dose with placebo control for the efficacy and safety to explore the clinically optimal dose of PM012 Tablet for therapeutic confirmatory (phase 3) clinical studies.
Older adults with Alzheimer's disease and other forms of dementia frequently develop challenging neuropsychiatric symptoms (NPS) as a result of their illness. Non-pharmacological strategies to manage these symptoms such as music, exercise, and participating in pleasant social events have been demonstrated to be safe and effective strategies to reduce these behavioral symptoms. Our project, Volunteers Adding Life in Dementia (VALID), will design and implement a volunteer-led program to reduce behavioral symptoms and improve the quality of life of older adults with dementia who are residing in long-term care facilities.
Antioxidants are important for having a good memory and for smart thinking when people get old, and that is important for everyone's quality of life. This research will find out if normal aging and Alzheimer's disease use up brain antioxidants. It will develop a new imaging tool that can help doctors to stop cognitive decline.
