Active clinical trials for "Alzheimer Disease"

A two months intervention in which two groups of cognitive disorders, Parkinson and Alzheimer's disease, will receive 50g/day of a commercial MCT supplement combined with supervised aerobic exercise 3 times/week. Cognition and ketones will be assess before and after the intervention, along with endocannabinoids plasma concentrations.

The overall (cross-sectional) objective of this study is to detect and describe the profile of AD-related blood biomarkers in a population with SCD (including individuals with MCI) with the ultimate goal of investigating their capacity to predict underlying AD pathology. Longitudinally, the β-AARC_BBRC2021 study fundamentally aims at assessing the ability of AD-related blood-based biomarkers to predict disease progression in the Alzheimer's continuum. To achieve these cross-sectional and longitudinal objectives, an exhaustive set of clinical, risk factors, cognitive, mental health and neuroimaging data will be collected, as well as blood and CSF samples, from which AD-related fluid biomarkers will be determined. As a secondary objective, we will investigate the efficacy and accuracy of the Altoida NMI as a novel digital biomarker for identifying patients with SCD or MCI that have underlying AD pathology (cross-sectionally) and to test the capacity of the Altoida NMI to track disease progression in these popoulations (longitudinally).

Safe and effective severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines may reduce the transmission of and achieve population immunity against the COVID-19 pandemic, which accounted for more than 3.75million deaths worldwide. With World Health Organization's (WHO) effort on ensuring equitable access to COVID-19 vaccines, vaccination rate may increase in the near future. On the other hand, vaccination hesitancy has emerged as a major hindrance on the global vaccination campaigns in certain areas due to safety concerns, social factors, and public health policies. For instance, a recent survey conducted in Hong Kong showed a low vaccine acceptance rate of 37%. Long-term safety concerns and post-vaccination events relayed by the social media maybe reasons for vaccination hesitancy. Among which, cerebrovascular accidents (CVA) after vaccination were one of the most frequently reported post-vaccination events. These reports ranged from ischemic strokes in elderly patients with multiple cardiovascular co-morbidities, to hemorrhage strokes in otherwise "young-and-fit" adults. While many of these events were investigated by the COVID-19 immunization expert committee, an important premise to address the apprehension of CVA after vaccination is the provision of evidence-based information of the impact of COVID-19 vaccines on brain health. In this prospective, longitudinal, observational study, we aim to elucidate the relationship between COVID-19 vaccines and cerebrovascular health in healthy citizens in a population-based cohort.

The purpose of the Trial-Ready Cohort - Down Syndrome (TRC-DS) is to enroll 120 healthy adults with Down syndrome (DS), between the ages of 25-55, into a trial ready cohort (TRC), and up to 250 participants in total including co-enrolled in the Alzheimer Biomarkers Consortium - Down Syndrome (ABC-DS) study. Participants enrolled in the TRC-DS will undergo longitudinal cognitive and clinical assessment, genetic and biomarker testing, as well as imaging and biospecimen collection. Using these outcome measures, researchers will analyze the relationships between cognitive measures and biomarkers of Alzheimer's disease (AD) to identify endpoints for AD clinical trials in DS that best reflect disease progression. To learn more about the study and participating sites, visit our study website at: https://www.trcds.org/. TRC-DS is collaborating with the Alzheimer's Disease Biomarker Consortium-Down Syndrome (ABC-DS) to allow study participants to be concurrently enrolled in both ABC-DS and TRC-DS, referred to as "co-enrollment". ABC-DS is a longitudinal, observational research study that is overseen at University of Pittsburgh Coordinating Center. ABC-DS participants who express interest in potentially joining a clinical trial in the future and who meet TRC-DS eligibility criteria, may choose to co-enroll in TRC-DS at an ABC-DS Site. Co-enrolled participants will adhere to the ABC-DS protocol and schedule of activities, but agree to share their data with the TRC-DS team and to receive invitations for future participation in clinical trials.

Insomnia is a highly common, chronic disorder that is distressful for the patient but also for caregivers and can give rise to a heavy burden on the healthcare team. Sleeping aids like benzodiazepines and other sedatives (e.g., zolpidem, zopiclone) have been widely used to help treat insomnia. However, sleeping aids are also known to cause adverse drug reactions such as drowsiness and dizziness, that increases the risk of falls, driving impairment, visual impairment, cognitive impairment, and upon discontinuation may cause paradoxical rebound insomnia, delirium, and nightmares all of which exacerbate the initial insomnia. All of the negative aspects of sleeping aid use are exaggerated for older, frail adults. Some patients experience an early (young-age) onset dementia with a substantial component of insomnia. Due to the many risks associated with traditional sleeping aids they are often inappropriate in adults living with cognitive impairment and/or frailty. Lemborexant comes from a new class of medications for insomnia. Lemborexant is a dual orexin receptor antagonist that blocks the binding of wake-promoting neuropeptides orexin A and orexin B to their receptors orexin 1 receptor (OX1R) and orexin 2 receptor (OX2R), which is thought to suppress wake drive. Unlike other traditional sleeping aids, lemborexant has not shown to be significantly associated with driving impairment, rebound insomnia, or dependence/withdrawal symptoms. Also, in clinical trials it only rarely causes the types of adverse events associated with benzodiazepines and other traditional sedatives and is less often associated with discontinuations due to adverse events. While lemborexant is available on the Canadian market it is unclear how this medication will be tolerated by patients living with an early onset dementia. Understanding the effectiveness and tolerability of lemborexant will be helpful in an N of 1 trial to understand the details of effect and effectiveness in individual patients.

The aim of this study is to assess the efficacy and safety of GSK4527226 in participants with early Alzheimer's Disease (AD) (including mild cognitive impairment [MCI] and mild dementia due to AD) of 2 dose levels of GSK4527226 compared to placebo.

CALM-IT is a Randomized, double-blind, placebo-controlled cross-over clinical trial. Safety and efficacy of JZP541 assessed for managing agitation in patients with AD and to identify novel biomarkers of agitation severity and treatment response.

The goal of this clinical trial is to test a mobile application amongst caregiver's supporting patients diagnosed with Alzheimer's Disease and Related Dementias (ADRD). The main question it aims to answer is: Will caregivers supporting patients diagnosed with ADRD utilize a mobile application to routinely report symptoms of the patients they care for?

This study aims to investigate the effectiveness and safety of rTMS treatment under the guidance of personalized Brain Functional Sectors (pBFS) in improving the cognitive ability of patients with mild Alzheimer's disease.

INTRODUCTION: Mild cognitive impairment (MCI) is a critical transitional stage in dementia related disorders. Dorsolateral prefrontal cortex (DLPFC), and the lateral parietal (LPC) cortex are subjected to neuropathological changes in MCI. Parietal memory network (PMN) integrity alterations and default mode network (DMN) alterations also occur in MCI. Transcranial direct current stimulation (tDCS) is a promising neuroprotective tool that modulates functional connectivity and might be useful to interfere with cognitive decline in relation to amnestic MCI (aMCI) and Parkinson's disease-MCI (PD-MCI) when applied to DLPFC and LPC. METHODS: This is a multicenter, randomized, and controlled study evaluating the effectiveness of anodal tDCS (atDCS ) applied bilaterally to the DLPFC/F3-F4 and LPC/ P3-P4 for 5 sessions with a total of 10 sessions in 14 days. The stimulation will be delivered with a 2 mA current frequency and will last 20 minutes a day for 5 days a week. The study consists of anodal, and sham control groups with a total of 120 participants with DLPFC and LPC anodal groups including 40 participants each and sham including 40 participants which are all between 45-80 years of age. At baseline and as an outcome measure, neurocognitive evaluation will be conducted using various tests standardized to use in the Turkish population. Functional magnetic resonance (fMRI) will be used to detect possible PMN and DMN alterations and hippocampal connectivity, and electroencephalogram (EEG) will be used to assess possible electrophysiological alterations that may happen as a result of atDCS. Baseline evaluation will be done before atDCS sessions and it will be repeated at the end of 14 days and 90 days. DISCUSSION: This study aims to explore the effectiveness of atDCS in PD-MCI, aMCI and to contribute to the literature in the field.
