Alzheimer's disease (AD) is the most common form of neurodegenerative disorders leading to dementia. Currently, there has been no effective drugs targeting this disease. Dysbiosis of the gut microbiota is considered to be associated with AD, and probiotic supplementation may positively affect cognitive function. However, there are few studies involving the relationship between intestinal microorganism and amnestic mild cognitive impairment (aMCI). In this project, taking the method of random, double blindness and control, the probiotic supplemented group with aMCI will take certain Bifidobacterium for a certain time. After that, the investigators aim to investigate the improvement of cognitive function and changes of intestinal microbial flora diversity via combining neuropsychological tests and 16S recombinant deoxyribonucleic acid (rDNA) high-throughput sequencing technique. Furthermore, based on the multi-modal neuroimaging techniques, the regulatory mechanism of intestinal microorganism in intervening aMCI will be revealed from the perspective of brain networks. In conclusion, these results are beneficial for understanding the therapeutic effect of gut microbiota as a non-drug treatment for early AD and further elucidating the potential brain mechanism, which are of great values in solving scientific and clinical practice issues.
Background: Deep brain stimulation (DBS) is used to modulate the activity of dysfunctional brain circuits. The safety and preliminary efficacy of nucleus basalis of Meynert (NBM)-DBS in Alzheimer's disease (AD) is proved in a recent phase 1 clinical trial, yet, the mechanism still unknown. Objective: 1. To compare the brain structure and functional circuits between a) AD patients with optimal drug treatment (ODT) plus NBM-DBS, b) AD with ODT and c) normal age-and sex-matched control. 2. To evaluate the clinical effectiveness of NBM-DBS in AD patients 60-75 year-old. 3. To evaluate the abnormal functional circuitry response to acute and chronic NBM-DBS in AD. Methods: A total of 30 subjects (10 subjects of AD with ODT plus NBM-DBS; 10 subjects of AD with ODT and 10 subjects of normal age-and sex-matched subjects) will be enrolled in this prospective, with normal control, Phase II study. Study tools will include clinical rating batteries, structure and functional imaging of magnetic resonance (MR) and positron emission tomography (PET), and electroencephalogram (EEG). Expected Results: NBM-DBS will be proved to be an safe and effective treatment modality in AD patients 60-75 year-old. Through multi-modal images and EEG analysis, the possible action mechanisms of NBM-DBS on memory circuit will be discussed. The study results may shed a light on this helpless neurodegenerative disease of dementia.
The RAATE proposal is designed to determine the effects of physical activity on risk factors for Alzheimer's Disease in older African American adults. The study will compare a physical activity program to an active control group. There are three main objectives of the protocol: 1) to determine if a physical activity intervention tailored to older African American adults is effective in modifying cognitive function associated with Alzheimer's Disease, 2) to determine if a physical activity intervention tailored to older African American adults is effective in modifying brain function and structure associated with Alzheimer's Disease, and 3) to determine if a physical activity promotion intervention tailored to African American adults is effective at enhancing physiological parameters. The primary endpoints for the study are episodic memory and executive functioning. The secondary outcomes include anthropometry, blood pressure, brain activation, cerebral blood flow, volume of whole brain and white matter hyperintensities, cardiorespiratory fitness, objectively measured physical activity, circulating hormones, and telomere length.
Agitation and aggression impose a tremendous burden on the individuals living with dementia, their families, caregivers, and healthcare systems. Neuropsychiatric symptoms of dementia (NPS) affect up to 80% of patients with Alzheimer's dementia (AD). The mechanisms of agitation in AD are poorly understood and the current interventions are only modestly effective while having serious adverse effects. In this study, the investigators propose to assess the mechanisms and treatment of neuropsychiatric symptoms in AD with the use of non-invasive, brain stimulation approaches. By applying magnetic stimulation to the surface of the head (transcranial magnetic stimulation - TMS) combined with electroencephalography (EEG), the investigators will be able to study the mechanisms of agitation and advance our understanding of AD. Further, the investigators will evaluate if transcranial direct current stimulation (tDCS) is effective to treat agitation dementia.
A Randomized Pivotal Study of RenewTM NCP-5 for the Treatment of Mild Cognitive Impairment due to Alzheimer's Disease or Mild Dementia of the Alzheimer's Type is a pivotal, single blind, parallel design, multi-site study intends to examine the efficacy and safety of RenewTM NCP-5 therapy in the treatment of Cognitive Impairment due to Alzheimer's Disease or Mild Dementia of the Alzheimer's Type. Subjects will be prospectively randomized to treatment or sham (in a 1:1 ratio) using stratification for Cognitive Impairment due to Alzheimer's Disease or Mild Dementia of the Alzheimer's Type, and Cardiovascular Risk (CVR) score at multiple sites. Subjects, ages 55-85, will be consented for 13 months and will receive thirty-five 60-minute RenewTM NCP-5 treatment sessions during a 7-to-12-week initial treatment period, and then transition to a lower frequency maintenance period (twice a week) for a total treatment period of 24 weeks.
The goal of this study is to characterize biophysiolgoical signals as a comprehensive profile of the nervous systems in order to understand interactions between the brain and body, while an individual performs naturalistic behaviors (ex. walking, pointing) and while breathing at a slow controlled pace. The investigators aim to study these interactions among a variety of populations, from healthy individuals to those with disorders such as Autism Spectrum Disorder(s), including those who may also have an ADHD (Attention-deficit/hyperactivity disorder) diagnosis, Asperger's Syndrome, Alzheimer's Disease, and/or Fragile X syndrome
The Etude Study is a multi-center, four-arm prospective dose-adjusting study designed to assess the tolerability, safety and efficacy of non-invasive sensory stimulation for patients with cognitive impairment.
The goal of this study is to test the efficacy of a mealtime intervention in respite care centers for people with dementia and their caregivers. Mealtimes become more challenging as dementia progresses causing nutritional and behavioral issues in the affected individuals. Using a train-the-trainer program built on the Partners at Meals model, volunteers in respite centers partner with caregivers and develop a mealtime plan that builds on the strengths of the person with dementia, and develop a supportive environment for change. A tele-health component is involved in the communication between the respite center volunteers/staff and families. Recruitment is limited to people attending the particular respite centers.
The Overture Study is a randomized, controlled, single-blind multi-center clinical trial using the GammaSense Stimulation system to study safety, tolerability, and efficacy in people with mild to moderate cognitive impairment.
