The importance of the proposed study concerns the understanding of the way in which each drug acts in each organism separately, both at the genome level and at the microbiome level. It is often observed that various treatments do not have the expected results in all patients, while, at the same time, new pathophysiological mechanisms for each disease are found. The involvement of the intestinal microbiome is one of these mechanisms and as it affects not only the progression of the disease but also the way in which drugs are metabolized (hence their action) should now be considered in every possible case. This led to the emergence of a new field of study related to personalized medicine, pharmacomicrobiomics. It includes microbiology, genomics, and pharmacology, and studies the changes that the human microbiome shows in drug exposure, action, and toxicity. However, this field is relatively new, and although there have been several reports of microbial biotransformation, there has been little in-depth research into the specificity of bacterial strains or the factors that can predict drug transformations. Therefore, this study will give the impetus for the individualized treatment, which will not only concern the genome (which is constantly evolving in recent years) but also the intestinal microbiome, which as mentioned above, is involved in many pathological conditions. Importance of the study Although a considerable number of studies have focused on the relationship between the microbiome and the pathogenesis of Alzheimer's Disease (AD), we have not seen any studies on the effect of drugs currently used in the treatment of AD (which are primarily cholinesterase inhibitors), such as rivastigmine, galantamine and donepezil and the NMDA (N-methyl-D-aspartate) glutamate receptor antagonist (memantine). There is also no reference to the composition and / or activity of the microbiome or to the effect of the latter on the pharmacokinetics and / or pharmacodynamics of these drugs. Also, although the human microbiome is influenced by genetic factors in the body, the effect of polymorphisms on the P-gp gene, which is involved in the pathophysiology of AD, the microbiome or its metabolites, has not been studied.
As part of Phase II of the NIH SBIR grant, the study will conduct a randomized controlled clinical trial in which the MapHabit system (MHS) will offer a caregiver training product that is linked to MHS, an Alzheimer's disease or related dementias (AD/ADRD) assistive technology product that uses visual maps to improve a patient's behavior and sense of autonomy. MapHabit's combined areas of focus, i.e., offer a single integrated product to address the caregiver and the person under this caregiver's care, are unique and will create a new standard in the field to reduce caregiver burden in the setting of caring for individuals with AD/ADRD. Additionally, the study will integrate enhanced user support modules, i.e., gamifying, dashboarding, and social networking, to improve the Caregiver Training Program (CTP) experience.The study will be a randomized controlled clinical trial, in which two conditions will be investigated: 1) control condition in which the MHS alone is incorporated in the participant's daily care and 2) experimental condition in which the MHS+CTP is implemented into the daily care received by participants. The sample size will be a total of 50 patient-caregiver dyads, 25 in each condition. The study duration will be a 6-month intervention.
proof-of-concept study to adequately design a larger trial to investigate the effect of supplementation of a probiotic (SLAB51) on AD biomarker.
This Phase I study will involve initial development and evaluation of an innovative cross-platform software app called All About Me (AAM), which will consist of Serious Digital Health Games (SDHGs) for PWD. The AAM app will assist staff in providing person-centered care and enable residents to improve relationships with one another and with staff, thereby promoting a sense of community. This Phase I study has three Specific Aims: (1) Develop an Alpha version of the AAM App, (2) Examine acceptability of and satisfaction with the AAM App, and (3) Examine the impact of the Resident Game Bundle / Survey Says Game on engagement/affect.
There is currently little symptomatic therapy for Alzheimer's Disease (AD) and nothing effective for individuals with Frontotemporal dementia (FTD). However, neuromodulation with transcranial direct current stimulation (tDCS) has the potential to be a clinically effective therapy for both AD and FTD. The challenge now is to specify the parameters and conditions under which tDCS is most effective to transition from the laboratory to clinical medicine. tDCS studies typically report significant group effects despite the variability demonstrated among participants, with some showing clear, meaningful improvement, while others only show statistical improvement or none at all. These variable results may be related to the conventional stimulation intensity level of 2mA. The investigators predict that administering tDCS at 4.0 mA, a more significant number of participants would show a meaningful response, and those who improve at 2mA may improve even more from 4.0mA due to having a larger electric field produced. The investigators aim to test this hypothesis in people with Alzheimer's Disease.

This research programme seeks to combine the resources of NHS primary care, with the leading spectroscopic work in low-magnetic fields of the Wilson Group (Nottingham Trent University) to demonstrate the potential for benchtop Nuclear Magnetic Resonance (NMR) spectroscopy in human clinical pathology. This is an instrument assessment study for point of care viability which will also result in enhanced patient care (pending their consent) in blood screenings and metabolic health data.
Dementia is associated with a variety of neurovascular and neurometabolic abnormalities. Traditional imaging techniques used to investigate such abnormalities, such as Positron Emission Tomography and functional Magnetic Resonance Imaging, are not always well tolerated, have expensive start up and running costs, and are limited with regards to the types of experiments that can be performed as they can be highly sensitive to movement, are noisy, and have physical restrictions. Near-infrared spectroscopy (NIRS) is a non-invasive neuroimaging technique which uses light in the near-infrared spectrum to detect relative changes in concentration of oxygenated and deoxygenated haemoglobin, and the oxidation state of Cytochrome C Oxidase. As such, NIRS can provide measures of brain oxygenation and metabolism. NIRS is less sensitive to movement, is well tolerated and has few contraindications. It is thus a promising candidate for use in clinics or in peoples' homes for monitoring dementia. In the present study, the investigators aim to use both dual-wavelength and broadband NIRS in a range of dementia subtypes, including Alzheimer's Disease and Dementia with Lewy Bodies, and severities, including Mild Cognitive Impairment, to identify how brain oxygenation and metabolism is altered in dementia and across various clinical subgroups. The investigators also aim to determine the relationship between brain oxygenation and metabolism in dementia, and use machine learning approaches to identify optical biomarkers for dementia.
Alzheimer's disease (AD) is the main cause of dementia. At present, AD is incurable. Memantine is recommended for the treatment of moderate and severe AD patients. Sodium oligomannate (GV-971) is a marine-derived oligosaccharide. It is proposed that it can reconstitute the gut microbiota, and inhibit neuroinflammation in the brain as observed in animal models. It reduces Aβ deposition in the brain of Aβ-transgenic mice. The reduction in both Aβ deposition and neuroinflammation may synergistically contribute to the improvement of cognitive impairment and delay the progress of the disease. China Food and Drug Administration(CFDA)approved it for the treatment of mild to moderate AD in 2019. Due to the different mechanism of memantine and GV-971, theoretically, they may synergistically improve cognitive function and delay disease progression. However, there is a lack of data on their effectiveness and safety. Therefore, the purpose of this study is to compare the efficacy and safety of memantine and GV-971 monotherapy and combination therapy in patients with moderate to severe AD, which is of great significance for guiding the treatment of moderate and severe AD.
