Active clinical trials for "Cognitive Dysfunction"

The purpose of this research study is to understand the factors that underlie changes in thinking and memory with increasing age. The investigators will test the usefulness of MRI, PET, and cognitive testing in detecting subtle changes in the brain that precede cognitive decline. An addendum to this study includes additional PET scans to examine the relationship between tau protein in the brain and cognitive decline. Tau is a protein that is known to form tangles in the areas of the brain important for memory, and these tau tangles are a hallmark of Alzheimer's disease. This sub-study research aims to look at the tau accumulation in the brain using an investigational drug called MK-6240, which is a radio tracer that gets injected prior to a positron emission tomography (PET) scan.

For many Veterans, success in achieving goals at work, school and in other aspects of life are top priorities. The abilities to regulate attention, remember key information, and stay calm and on track are fundamental to this success. Unfortunately, Veterans who have experienced a traumatic brain injury (TBI) often struggle with these very abilities, and a number of barriers can make it difficult for them to access the help Veterans need. Tele-rehabilitation has the potential to overcome some of these barriers and increase access to care, enabling providers to better reach Veterans 'where they are' in their communities. This project will assess two different approaches to brain injury rehabilitation that seek to help Veterans build personal strengths to better accomplish their goals. Both approaches will be delivered remotely via tele-rehabilitation and augmented by digital apps to best support Veterans' learning in community settings outside the VA.

This research study is being done to determine if indices derived from monitoring brain wave activity while under general anesthesia will predict the likelihood of post-operative cognitive dysfunction in patients over 60 years old.

Every year, approximately 9,000 Parkinson disease (PD) patients undergo deep brain stimulator (DBS) placement into the subthalamic nucleus (STN-DBS). Studies suggest that PD patients with mutations in the glucocerebrosidase (GBA) gene are at high risk for cognitive impairment and approximately 10-17% of subjects undergoing DBS carry GBA mutations. There may be an interaction between STN-DBS, which also impairs cognitive function, and GBA, resulting in worsened cognitive function. This project will 1) determine the relationship between GBA mutation status and post-operative STN-DBS cognitive function, 2) broaden genotype-phenotype relationships of GBA mutation carriers and 3) provide scientific knowledge regarding the longitudinal cognitive effects of DBS in GBA mutation carriers through repeated neuropsychological testing.

This clinical trial is being conducted to see if brain stimulation and brain training together improves cognitive functioning and mood in older adults diagnosed with Mild Cognitive Impairment (MCI). Brain stimulation will be done using repetitive Transcranial Magnetic Stimulation (rTMS). Brain training will be done using immersive virtual reality cognitive training (iVCT) program. The goals of this clinical trail are as follows: Examine if rTMS+iVCT intervention can improve and sustain objective cognitive functioning in individuals with MCI more than control or rTMS only groups Examine if rTMS+iVCT intervention improves participants mental health symptoms, functional abilities, and quality of life more than control or rTMS only groups Examine the impact of rTMS+iVCT intervention on caregiver burden. Eligible participants will be assigned to a standard treatment (no intervention control) group, rTMS only group of rTMS+iVCT group. All participants will undergo baseline assessment to evaluate their cognitive, emotional, and functional abilities. Those in the rTMS only group will receive rTMS treatments for five days per week for two weeks (total of ten sessions). Those in the rTMS+iVCT group will receive rTMS treatment followed by iVCT training for five days a week for two weeks (total of ten sessions). All participants will then repeat testing 2 weeks and three months after baseline testing to assess for possible treatment related changes and lasting effects.

The study, identified as VIX001-PACS-01, is a Phase 1, open-label, dose-escalation trial evaluating the safety, tolerability, preliminary efficacy, and dose effect of VIX001, an amniotic fluid product, in patients with Post-Acute COVID-19 Syndrome (PACS) and cognitive impairment. Conducted at the University of Miami Hospital and Clinics, the trial aims to enroll up to nine participants, or up to 18 using a 3+3 dose escalation design. Intravenous injections of VIX001 will be administered at three ascending doses (1 ml, 3 ml, or 10 ml), and participants will be assessed for safety, cognitive impairment, pain, activity, and quality of life at baseline and various timepoints. The primary objective is to evaluate the safety of VIX001, while secondary objectives include assessing its potential efficacy and patient-reported outcomes. The study duration is expected to last approximately 18 months, including enrollment, evaluation, and post-study observation periods. The findings will contribute to understanding VIX001's safety and efficacy in treating PACS-related cognitive impairment.

Cerebral small Vessel Disease (cSVD), characterized by an alteration of the structure and function of small penetrating brain arteries, is highly prevalent in older persons from the general population and represents a leading cause of stroke and a major contributor to cognitive decline and dementia risk. In France >4 million persons aged 60+ are estimated to have moderate to extensive covert cSVD (ccSVD), i.e. features of SVD on brain imaging without a history of clinical stroke. Better detection and management of covert cSVD would have a major impact on preventing disability and costs related to stroke, cognitive impairment and dementia. However, there are no specific mechanistic treatments for cSVD and hardly any recommendations worldwide on how to prevent and treat cSVD and related cognitive impairment. The aim of the present study, through the identification of novel cutting-edge multimodal biomarkers, is to develop innovative diagnostic and risk prediction tools for cSVD and its complications and to contribute to accelerating the discovery of novel drug targets and therapeutics strategies for cSVD.

TRACE-IMPAIR is a prospective, clinical study of consecutive patients that evaluates the relationship between heart failure (HF) and cognitive impairment in relation to carotid and cerebral flow. The carotid and cerebral flow will be assessed using Doppler ultrasonography, and cognitive function will be estimated during routine neuropsychological tests. It is an observational, three(natural)-group, single-center study. It is also an Academic Registry - the scientific activity of the Faculty of Medicine, Collegium Medicum, Jagiellonian University, and John Paul II Hospital.

This is a basic neuroscience study of modulating brain oscillations involved in cognitive control. We will record brain signals and stimulate specific regions of the brain in human participants who are undergoing monitoring for epilepsy surgery. It is not a clinical trial for treating any disease.

The Digital Cognitive Multi-domain Alzheimer's Risk Velocity (DC MARVEL) study is a 2-year randomized controlled trial on dementia prevention. The purpose of this study is to determine the effect of a digital cognitive health program on dementia risk, cognitive function, and general health outcomes in middle age to older adults compared to a control group that receives health education.
