Filter by:This an open label study to assess the pharmacokinetics of CT1812 in normal healthy volunteers.
The investigators explore the effectiveness of grounding as a non-pharmacological therapy for treating sleep disturbances, anxiety, and depression in patients with mild AD.
Dementia resulting from AD is associated with vascular function decline and involves a pro-inflammatory state. In our Phase 1 trial, Lomecel-B treatment met the primary safety endpoint, with no safety concerns, and showed potential to improve clinical assessments. Mechanistically, Lomecel-B treated subjects had higher serum concentrations of pro-vascular and anti-inflammatory biomarkers relative to placebo. This trial builds upon those preliminary Phase 1 results, and is designed to evaluate the safety profile of multiple infusions of Lomecel-B, and to investigate provisional efficacy of single dosing versus multiple dosing of Lomecel-B on cognitive function and biomarkers in AD subjects.
The objective of this qualitative study is to create a better understanding of patients' mental model of health data engagement interfaces and tools (such as Dynamic Consent). The researchers will focus especially on those people who - plausibly - require adjusted communication particularities and interaction modalities due to a cognitive impairment stemming from a neurodegenerative disease. Taking into account the specific characteristics of patients with dementia, the goal of this study is to investigate how to communicate according to patients' personal skills and capabilities and identify both the proper support mechanisms for engagement 2.0 consent as well as feedback mechanisms (return of research results). Through a focus group & interview setup, this study will discern design requirements and propose design recommendations for the (future) development of health data engagement interfaces.
This study seeks to measure changes in cognition through verbal and visual test procedures and changes in biomarkers of Alzheimer's disease and inflammatory and metabolic parameters that can be measure in the central nervous system (CNS) with advanced neuroimaging techniques in patients treated with NE3107 (17a-ethynyl-androst-5-3b,7b,17b-triol).
The purpose of this study is to evaluate the safety and tolerability of multiple ascending doses of MK-8189 in participants with Alzheimer's Disease (AD) with or without symptoms of agitation-aggression and/or psychosis.
Open-label, single-dose study to assess the absorption, metabolism, excretion and mass balance of [C14] CT1812
The 'Western diet' characterized by high fat feeding (HFF) is a risk factor for Alzheimer's disease (AD); however, little is known about mechanisms. Paradoxically, individuals who carry the AD risk gene APOE E4 cognitively improve after HFF and show different metabolic responses to fat intake. These responses include a more pronounced drop in systolic blood pressure and a decrease in cerebrospinal fluid glucose and lactate levels. This proposal will further examine the brain metabolic response to HFF using non-invasive imaging. Cerebral blood flow (CBF) as assessed by functional MRI is increasingly utilized to investigate brain function, given that CBF is tightly coupled to brain metabolism. Acute changes in CBF have been described in response to carbohydrate ingestion in regions important for learning and memory; however, no one has yet assessed CBF response to lipid. Here investigators propose to characterize CBF changes to a high fat drink in older adults. This study will include a time course assessment as well as analyses of global and regional change in CBF. These data would serve as feasibility pilot data for an R01 application which would include cognitive and peripheral metabolic data. These types of studies will provide a clearer picture of acute brain metabolic response to HFF in older adults, including the effects of APOE.
This is a non-randomized, non-treatment, observational study designed to discover correlations between retinal imaging and amyloid PET imaging. Subjects will be recruited to the clinical cohort from referring physicians. Subjects may be participants from existing studies and clinical practices
There is a need for caregiver-initiated and -implemented non-pharmacological interventions directly to and for the person with dementia, including environmental assessment and modification, as first-line treatments for behavioral and psychological symptoms of dementia (BPSD) in persons living with dementia (PLWD). Delivered via telehealth, Harmony at HOME (H@H) aims to train caregivers of persons with moderate to severe ADRD in the skills of assessing and modifying the home environment to promote "person-environment fit," a concept that posits that the ability to access features within a built environment (e.g. bathroom, stairs,) or that factors within the environment itself (lighting, noise level, temperature), especially when linked with individualized social support, contribute to or even shape behavior. In addition to the intervention, the first 10 caregiver participants to enroll will also be invited to participate in two focus groups that will be facilitated during and after the intervention. The first focus group focuses on experiences as a dementia caregiver in rural areas. The second focus group focuses on providing feedback regarding caregivers' perceptions, acceptability, and usefulness of the H@H intervention. These focus groups will be conducted as structured interviews with open-ended questions that encourage participants to share their experiences.
