Active clinical trials for "Alzheimer Disease"

The primary objective is to examine the efficacy of 8-weeks of a locally developed brain-computer interface based system (BrainpalTM)intervention for improving attention and memory in normal elderly. We hypothesize that elderly who have completed the training program will have significant improvement in their attention and memory compared to the controls, based on the Repeatable Battery for the Assessment of Neuropsychological Status.

Objective of this study is to evaluate the safety, tolerability, pharmacokinetics and preliminary pharmacodynamic effects of multiple doses of Gantenerumab in subject with mild to moderate AD.

This study will test the use of venlafaxine to treat the depression in Alzheimer's Disease. Venlafaxine works by increasing natural substances in the brain (serotonin and norepinephrine) that help maintain mental balance. Alzheimer's disease (AD) is the commonest neurodegenerative disease of aging and the cause of major financial and emotional burden to patients, families and caregivers, and society. Depression is a very common symptom of AD, affecting as many as 50% of patients over their illness. Depression in AD (Alzheimer's disease) contributes greatly to patient disability and caregiver distress. Neither psychosocial interventions nor psychotropic medications have proven effective to date for the treatment of depression in AD.Venlafaxine is approved by the U.S. Food and Drug Administration (FDA) for the treatment of major depression but it is not known whether or not it can help depression in Alzheimer's Disease.

Current therapeutic approaches for the treatment of neurodegenerative diseases like Alzheimer disease (AD) offer limited and often transient symptomatic benefits to patients but do not mitigate the insidious loss of neuronal cells. In this trial the investigators will evaluate Efficacy and Tolerability of MLC601 as a neuroprotective in Patients with Mild to Moderate Alzheimer Disease who Were Unable to Tolerate or Failed to Benefit from Treatment with Rivastigmine.

To compare the efficacy of 2 fixed doses of brexpiprazole with placebo in participants with agitation associated with dementia of the Alzheimer's type.

This is a national multicenter, double-blind, randomized, parallel-group trial of 12 months in duration. Following a 4 week wash-out period, subjects will be randomized to one of 2 treatment groups: (1) galantamine CR 24 mg/day with dose-titration over twelve weeks[maintenance phase from week 9], (2) a combination of galantamine CR 24 mg/day plus memantine 10 mg b.i.d. with a dose titration of sixteen weeks (12 weeks for galantamine [maintenance phase from week 9], additional 4 weeks for memantine).

To investigate the efficacy of Exelon capsule at maximal tolerated dose in mild to moderate Chinese AD patients via dosage titration from 3mg/d to 12mg/d in a 16 weeks duration

This trial seeks to establish the feasibility of implementing a ketogenic, modified Atkins diet (MAD) to older adults with mild cognitive impairment (MCI) or early Alzheimer's disease (AD) living in the community. A secondary aim is to determine whether adherence to the MAD results in better cognitive test scores than adherence to a non-ketogenic control diet. A final aim is to determine the role of apolipoprotein E (ApoE) genotype in participants' response to the MAD. Participants will be randomly assigned to a 12-week trial of either the MAD or a placebo diet based on the National Institute on Aging's recommendations for senior nutrition.

This study will compare the effectiveness of different combinations of 5 types of behavioral interventions across patient-centered outcomes. It will also evaluate which outcomes (e.g. quality of life, cognition, function, mood) matter most to people at risk for dementia and their care partners. The results of this study have the potential to direct patients, families, and health care providers as to which combinations of behavioral interventions provide the greatest potential impact on which dementia prevention outcomes. Greater use of behavioral strategies that are targeted to the outcomes of most important to the patient will likely improve patient compliance and treatment adherence. This, in turn, can lessen the need for medication, health care, and long term care utilization.

General Investigational Plan Study Objectives The goal of this proposal is to determine whether enhancing brain glucose utilization minimizes cognitive decline in patients with Amnestic Mild Cognitive Impairment (AMCI) or mild Alzheimer's disease (AD) dementia. We propose a proof of concept double-blind, placebo controlled pilot study to determine if increasing brain thiamine availability with the investigational new drug benfotiamine, will minimize the decline in glucose utilization and slow the cognitive decline associated with the progression AMCI/AD dementia. Specifically, our objectives are two-fold: To test whether increasing brain thiamine by administering 600 mg per day (300 mg/morning and 300 mg/evening) of benfotiamine for one year can slow cognitive decline in these patients as measured with the Alzheimer's Disease Assessment Scale (ADAS-COG). To determine whether increasing brain thiamine availability with 600 mg (300 mg/morning and 300 mg/evening) per day of benfotiamine for one year can slow the decline in brain glucose metabolism in these patients as measured with Fluorodeoxyglucose Positron Emission Tomography(FGPET) in the posterior cingulate. We will also carry out the following secondary objectives: Assess if there are differences in secondary clinical outcome measures (NPI, ADCSADL, CDR, Buschke) between benfotiamine and placebo groups and whether specific cognitive domains (ie: activities of daily living, learning and memory verbal memory, behavioral, etc.) are driving these changes. Compare ADAS-COG change scores in the benfotiamine and placebo groups within and between strata that were defined by initial cognitive impairment, to attempt to identified the population that most benefits from benfotiamine. Compare changes in glucose utilization between the benfotiamine and placebo groups in secondary Regions of Interest (ROIs) including the hippocampus, prefrontal regions and entorhinal cortex. Compare changes in whole brain glucose utilization between the benfotiamine and placebo groups using statistical parametric mapping (SPM). Assess the correlation between changes in glucose utilization with changes in ADAS Cog. Determine if ApoE4 genotype alters the response to benfotiamine.
