Glutathione, Brain Metabolism and Inflammation in Alzheimer's Disease

Alzheimer Disease

Alzheimer's disease (AD) is associated with significant, progressive cognitive decline. Key defects in mitochondrial fuel metabolism insulin resistance, inflammation and decreased brain glucose uptake are linked to AD. This trial will investigate the effects of supplementing glycine and N-acetylcysteine vs. alanine as placebo on these defects in AD, and examine the effects on cognition.

The Ketogenic Diet for Alzheimer's Disease

Alzheimer DiseaseEarly Onset

The ketogenic diet (KD) is a metabolic shift, which stimulates the liver oxidation of fatty acids to produce ketone bodies. These ketone bodies represent an alternative fuel source for the brain. The benefits of KD in epilepsia have been demonstrated for decades. This diet may also provide benefits in Alzheimer's disease (AD) where neuronal glucose utilization declines from the early stage. Besides, the KD could decrease neuroinflammation, oxidative stress and enhance mitochondrial biogenesis. In murin models of AD, KD or Medium Chain Triglycerides consumption were associated with lower neuroinflammation but also with a diminution of neuropathologic features of AD (amyloid and tau lesions in the brain). Moreover, behavioural effets and improvements in memory and motor function have been highlighted. In humans, recent studies suggest cognitive benefits (memory, executive function) in AD, including in the Mild Cognitive Impairment (MCI) stage. The feasibility and the adherence to the diet proved to be correct, in small samples, in particular in MCI individuals over a short follow-up period (3 to 6 months). This study aims at examining the feasibility of a KD followed-up for one year in participants with early AD (N=70). Change in brain metabolism will be assessed using PET scan after 12 months, comparing KD with control diet. The effects on cognition, quality of life and daily living functioning will be analysed. The safety, nutritional changes and adhesion to the diet will be monitored throughout the study.

Using Technology to Support Care Partners for Persons With Alzheimer's Disease: Tele-STELLA

DementiaAlzheimer Disease2 more

The purpose of this study is to test a revised psychoeducational intervention to help Care Partners for family members with dementia understand and reduce the distressing behaviors that come with progressive dementia. Tele-STELLA (Support via TEchnology: Living and Learning with Advancing Alzheimer's disease and related dementias) is a multicomponent videoconference-based intervention designed to facilitate effective management of behavioral and psychological symptoms common to the later stages of dementia. In the Tele-STELLA intervention, professionals ("Guides") meet with family members ("Care Partners") who care for persons with dementia. Working together, the Care Partners and Guides identify strategies to address upsetting behaviors. The goal of this intervention is to reduce upsetting behaviors and, thus, Care Partner burden.

The Wandering Nerve: Gateway to Boost Alzheimer's Disease Related Cognitive Performance

Aging

In this research study the investigators want to find out if a non-invasive electrical brain stimulation method called RAVANS (also called tVNS) can have a beneficial effect on cognition in older individuals. The investigators also want to understand whether certain individual factors contribute to the effect of RAVANS on cognition. RAVANS is only used in research studies.

Faith-Based Toolbox for African Americans With Dementia

Alzheimer DiseaseDementia

The purpose of this study is to create and test faith-based activities that might be useful for African American adults with moderate and severe dementia and their caregivers. A total of 60 people will take part in the intervention; 30 people with moderate and severe dementia and 30 family caregivers.

Gamma-Music Based Intervention for Mild Alzheimer's Disease

Alzheimer Disease

The study will test and refine a novel brain-stimulation tool using gamma-frequency lights coupled with self-selected music for a gamma-music-based intervention for participants with mild Alzheimer's Disease. Results will yield a gamma-stimulation protocol that reliably influences brain activity (Aim 1), is adaptive, motivating and rewarding to use (Aim 2), and will generate predictions as to who might benefit the most from gamma-MBI (Aim 3). By bridging the gap between neurostimulation and behavioral intervention by combining music therapy with gamma- band neurostimulation, the present project aims to find a sustainable intervention that delays the progression of AD.

HP Xenon-129 fMRI of Healthy Volunteers and Participants With Alzheimer's Disease

Alzheimer Disease

This study involves imaging participants' brains using MRI. The goal is to develop a high-resolution, high-sensitivity imaging tool, hyperpolarized xenon functional brain magnetic resonance imaging, which can provide more sensitive measurement of brain function, facilitating the development of drugs for more successful treatment of Alzheimer's disease.

APOE Genotype and Diet Influences on Alzheimer's Biomarkers

Alzheimer's Disease; Dementia

This study involves the collection of cognitive and biomarker responses to HIGH and LOW meals in healthy older adults with and without the APOE E4 genotype. Subjects will eat the meal after an overnight fast, followed by cognitive testing, spinal fluid and blood collection. The HIGH meal will be a meal high in saturated fat and high glycemic index foods vs. LOW meal which will be low in saturated fat and low glycemic index foods.
