Filter by:In a retrospective analysis of data from 1100 patients, disease-delaying effects of Cerefolin®/CerefolinNAC® were examined in terms of cognition. The purpose of the current study is to expand the retrospective study dataset by prospectively collecting additional biomarker and imaging data.
This study will evaluate the effects of daily dosing of AC-1204 on cognition, activities of daily living, resource utilization, quality of life, pharmacokinetic measures and safety among participants with mild to moderate Alzheimer's Disease.
The primary purpose of this study is to determine whether ELND005 is effective in treating symptoms of agitation and aggression in patients with Alzheimer's disease
The purpose of this study is to demonstrate that the change of attention measure is correlated with the changes of caregiver's burden after treatment with galantamine.
To establish a cutoff value using a ratio of CSF tau to Aβ42 (tau/Aβ42) for distinguishing patients wth mild to moderate Alzheimer's disease (AD) from health elderly control subjects. The investigators hypothesize that a cutoff can be found that has at least 80% sensitivity and 60% specificity.
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.
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.
