Active clinical trials for "Alzheimer Disease"

This study will investigate the safety and efficacy of a Tyrosine Kinase Inhibitor (TKI) called Nilotinib BE (bioequivalent) in individuals with Early Alzheimer's disease (EAD). This is a multi-center double blinded, Phase 3 study, that will enroll patients for three years in approximately 50 centers nationwide. The total duration of the study will be for five years.

This trial will assess feasibility of a non-pharmacological intervention for persons living with Alzheimer's disease and related dementias (ADRD) to improve behavioral and psychiatric symptoms of dementia and functional performance. Using a two-arm, prospective randomized controlled trial, 38 dyads (person with ADRD and caregiver) will complete an 8-week telehealth occupational therapy intervention provided via Zoom with caregivers and persons with dementia or receive an active control with 8 telehealth sessions to discuss publicly available caregiver education with a non-clinical research assistant.

The purpose of this study is to investigate the effects of dual-task training on balance, fear of falling, cognitive functions, dual-task performance, depression and quality of life in individuals with Alzheimer.

The goal of this clinical trial is to demonstrate potential improvements in clinical trial methods relating to dementia and cognitive decline. The main questions it aims to answer are: Can an intervention's outcome be better assessed by a latent variable ("δ") integrating cognitive performance with functional status? Can latent biomarkers of δ guide the selection of an intervention that will modulate dementia severity? Can a latent variable, derived from information collected remotely from caregivers, preselect subjects most likely to respond to the intervention? Is the effect of the intervention in fact medicated by changes in the targeted biomarker? In this case, the biomarker will be a latent variable derived from several proteins measured in blood (i.e., so-called "adipokines"). The intervention will be donepezil, a medication approved for the treatment of Alzheimer's Disease, but only recently associated with adipokine changes. Participants with cognitive impairment and their caregivers will be interviewed by telephone and those with cognitive impairment will be treated for six-months with donepezil. On the basis of the caregiver's report, the cognitively impaired subjects will be assigned to two groups based on a prediction of their response to donepezil. Researchers will compare those groups to see if dementia severity, as measured by δ, improves in predicted responders, and whether the change in the d-score is mediated by changes in adipokines.

Sleep apnea is characterized by temporary pauses or stops to participant's breathing. Currently, sleep apnea is diagnosed using an in-lab sleep study, which involves spending a night in a sleep laboratory hooked up to wires on the head, chest, and legs. However, this is not feasible for many older adults. To overcome this barrier, the investigators will utilize an investigational vital signs monitor - the Advanced NeoNatal Epidermal (ANNE) Vital Sign System (Sibel Health, Evanston, IL,USA). The primary objective of this study is to test the hypothesis that sleep apnea is associated with accelerated cognitive decline in older adults at risk for dementia. The investigators will measure sleep apnea at baseline and 12 months later and relate this to cognitive function at the same time points. Sex-stratification will be used in analyses as appropriate. Qualitative feedback forms will be used to collect information about participant ease of use and experience with the ANNE Vital Sign System.

The main aim of the study is to characterize and understand the pathological mechanisms underlying the motoric cognitive risk syndrome, which is a predictor of Alzheimer disease.

The goal of this observational longitudinal study is to investigates whether tear fluid is a non-invasive source of biomarkers for Alzheimer's disease. The main aim of the study is to evaluate diagnostic accuracy measures (sensitivity and specificity) of tear and retinal biomarkers to discriminate individuals with and without neurodegeneration. Tear fluid from participants will be collected non-invasively with Schirmer's strips, which is a small paper strip placed in the lower eye lid for a maximum of 5 minutes. Additionally, standard, ultra-wide field and cross-sectional retinal images will be obtained.

In this study, the investigators will use a novel electroencephalogram (EEG) system that participants will wear during a single in-person research session to investigate whether ERPs are now ready for validation as a tool clinicians can easily implement to increase diagnostic accuracy and confidence. This EEG will not be used to treat, cure, mitigate or diagnosis any disease and there will be no safety or efficacy data collected about the machine for any purpose including support of FDA submission. The investigators will compare the ERP data to that of neuropsychological testing in order to determine the degree of correlation between these two measures. Questionnaires on cognition, mood, and fluency will be administered prior to the EEG to establish a baseline. ERP data from the EEG session will be compared with the results of the neuropsychological battery in order to determine whether the implementation of ERPs in the existing workflow of clinicians can aid in diagnostic accuracy, thus altering clinical management.

The goal of this clinical trial is to test 6 months of aerobic exercise in older adults who are 65 years or older and have mild cognitive impairment (MCI) or probable/possible mild Alzheimer's Disease. The main questions it aims to answer are: test the effects of aerobic exercise on aerobic fitness, white matter hyperintensity (WMH) volume, and patient-centered outcomes; identify the best exercise to improve aerobic fitness and reduce non-responses over 6 months; and examines the mechanisms of aerobic exercise's action on memory in older adults with early AD. Participants will receive 6 months of supervised exercise, undergo cognitive data collection and exercise testing 5 times over a year span, have an MRI brain scan 3 times over a one-year span, and have monthly follow-up discussions on health and wellness.

Learning Skills Together (LST) is a 6-week psychoeducational intervention focused on complex care (nursing) tasks completed by family caregivers to persons living with Alzheimer's Disease and related dementias. This study aims to test the efficacy of LST at reducing caregiver depression and negative appraisal of behavioral symptoms of dementia by building caregiver self-efficacy. To do this, eligible participants will be randomized into an intervention group (LST) or a control group condition focused on healthy living for family caregivers. Participants will be asked to complete surveys before and after participating in the intervention or the control condition to determine whether change in hypothesized outcomes can be attributed to the intervention condition.
