Filter by:This is a Phase 3 global, multicenter, 52-week, open-label extension (OLE) rollover study for subjects completing study KAR-031 or KAR-032. Subjects (randomized or non-randomized) who complete the 38-week KAR-031 or KAR-032 study will be eligible to enroll in KAR-033. The primary objective of the study is to assess the long-term safety and tolerability of KarXT in subjects with psychosis associated with Alzheimer's Disease.
This project will test the effectiveness of a novel intervention consisting of unobtrusive, low-intensity, horizontal and vertical lights that outline the bathroom or entry way doorframe in residents' rooms and provide visual cues to promote postural stability. Specifically, this pragmatic crossover trial will enroll 390 assisted living residents with dementia and follow them for one year, comparing the incidence of nighttime falls during the lighting condition to the incidence of falls during the control condition; secondarily, it will determine whether and to what extent the intervention effect is modified by resident- and environmental-level risk factors, and satisfaction with the lighting system.
The DPPOS AD/ADRD project will address the overarching question: What are the determinants and the nature of cognitive impairment among persons with pre-diabetes (PreD) and type 2 diabetes (T2D), who are a high-risk group for cognitive impairment and represent a large fraction of the United States (US) population? This U19 proposal addresses the National Alzheimer's Project Act goal to "prevent, halt, or reverse AD" in the high-risk group of persons with pre-diabetes and type 2 diabetes, who represent over half of the population aged 60 years and older in the US.
The goal of this clinical trial is to test the effects of different types of exercise on brain health and Alzheimer's risk in older African Americans. Specifically, the main question[s] it aims to answer are: - What is the effect of a Cardio-Dance Fitness (CDF) vs. a Strength, Flexibility, and Balance (SFB) intervention on a cognitive marker of Alzheimer's risk, generalization? - What is the effect of the CDF vs. SFB intervention on a fMRI biomarker of Alzheimer's, neural flexibility, and do improvements in neural flexibility mediate improvements in generalization? - Do ABCA7 genotypic variations moderate the efficacy of the CDF vs. SFB intervention for reducing Alzheimer's risk? Participants will undergo-- at baseline and post-test-- health assessments, cognitive tests, and structural and functional magnetic resonance imaging (fMRI), and a blood-draw to assess Alzheimer's risk biomarker levels.
The proposed project will assess long-term changes to health/lifestyle, advanced planning, and research engagement that Black and White patients with Amnestic Mild Cognitive Impairment (aMCI) make following disclosure of positron emission tomography-based amyloid and tau burden and associated risk of conversion to Dementia-Alzheimer's Type. Healthcare access will be explored as potential barrier to or facilitator of behavior change.
The goal of this open-label extension study is to assess long-term safety and tolerability of simufilam 100 mg in subjects who have completed the RETHINK-ALZ or REFOCUS-ALZ Phase 3 clinical trials.
Clinically Designed Improvisatory Music (CDIM) is a form of improvised music based on calm-inducing sound parameters which brought relief to our cohort of neurology patients. As a direct sound-based approach, CDIM does not rely on autobiographical memory and may have wider applicability and generalizability. We wish to examine if CDIM decreases anxiety in 15 cognitively healthy individuals and 15 Alzheimer Disease patients with anxiety (AD-A).
The research plan to enroll 15 simple snoring patients (apnea/hypopnea <5, control group), 30 severe OSA patients (apnea/hypopnea >30, treatment group), and 15 mild cognitive impairment patients (comparative group). All patients complete Mini-Mental State Examination, peripheral blood sample for plasma Aβ42, Aβ40, Aβ42/Aβ40, Tau, NfL; amyloid deposit in18F-florbetapir PET; and Taiwan smell identification test. Thirty severe OSA patients (AHI>30, treatment group) receive comprehensive upper airway surgery with/without bariatric surgery and repeat postoperative assessment in polysomnography and aforementioned examinations 1 year later.
This study focuses on the population of Alzheimer disease (AD). Based on Aβ(A)-Tau(T)-Vascular(V)-Neurodegeneration(N) (ATV(N))-AD evaluation system of NIA-AA Association, it can accurately diagnose and predict early AD. Positron emission tomography (PET) - magnetic resonance (MR) was used to perform Aβ、Tau molecular imaging, representing A and T in the system respectively; The quantitative detection of glucose metabolism in the brain by fluorodeoxyglucose PET (FDG-PET) can reflect the degree of neuronal damage (N); In addition, PET-MR can be used to synchronously evaluate the patients' vascular comorbidity (SVD load score) (V). Through the preliminary construction of this system, to clarify the central deposition pattern of Aβ、tau protein and the characteristics of FDG metabolism; To clarify the correlation between PET-MR imaging indexes and the progression of early cognitive impairment in AD, and to clarify the role of degeneration and vascular factors in the occurrence and development of AD; To provide a preliminary basis for the subsequent establishment of a molecular imaging model for the prognosis of early AD.
The main goal of the ENACT (ENgaging in Advance Care planning Talks) Group Visit intervention is to integrate a patient-centered advance care planning process into primary care, ultimately helping patients to receive medical care that is aligned with their values. The ENACT Group Visit intervention involves two group discussions about advance care planning with 8-10 patients who meet for 2-hour sessions, one month apart, facilitated by a geriatrician and a social worker. This study will compare the ENACT Group Visit intervention to mailed advance care planning materials.
