Filter by:This platform protocol is designed to be flexible so that it is suitable for a wide range of settings within health care systems, for remote settings, and in community settings where it can be integrated into COVID-19 programs and subsequent treatment plans. This protocol is a prospective, multi-center, multi-arm, randomized, controlled platform trial evaluating potential interventions for PASC-mediated cognitive dysfunction. The hypothesis is that PASC associated dysfunction in cognitive domains, such as executive function and attention, may be improved by interventions that selectively focus on enhancing those domains.
This is a single site, randomized exercise trial with individuals at least 50 years of age living with HIV who experience suboptimal cognition. The overall goals of this proposal are to determine whether 12 weeks of structured high-intensity interval training (HIIT) can overcome vascular and cognitive impairments (Aim 1) to a greater extent than continuous moderate exercise. Additionally, investigator will seek to identify barriers to engagement in exercise and the participants' perceptions of the study and exercise interventions (Aim 2). This study will enroll 60 participants in Birmingham, Alabama. Data collection will occur at each visit, with baseline data collected at the initial visit with a 3-month follow-up occurring following completion of the intervention.
The purpose of the study is to test whether low level electric stimulation, called transcranial Direct Current Stimulation (tDCS), on the part of the brain (i.e., presupplementary motor area) thought to aid in memory will improve verbal retrieval in multiple sclerosis patients. The primary outcome measures are neuropsychological assessments of verbal retrieval, and the secondary measures are neuropsychological assessments of other cognitive abilities and electroencephalography (EEG) measures. Additionally, the study will examine the degree to which baseline assessments of cognition and concussion history predict responses to treatment over time, both on assessments administered within the intervention period and at follow-up.
Dementias secondary to cerebrovascular diseases are of significant epidemiological and clinical relevance. As a result, the management of individuals with comorbid dementia should involve early diagnosis, effective treatment, and patient-centered care planning, both in specialist and in non-specialist settings. It is well known that physical exercise can improve various aspects of health, including resistance, balance, strength, and cognitive functions such as attention and executive performance. However, the efficacy of cognitive rehabilitation is still not definitive and requires further clarification. Preliminary evidence suggests that a combination of cognitive and motor training along with novel technological approaches has the potential to maintain or improve compromised cognitive function more effectively compared to a single intervention. A multidomain intervention could enhance cognitive functioning in elderly individuals with multiple morbidities. In the present study, patients with early neurocognitive impairment based on a vascular disorder or due to multiple etiologies, as defined by the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition, will be screened in an outpatient multidisciplinary setting and subsequently undergo different models of rehabilitation training. Primary aim of this study: - Assess the effectiveness of different rehabilitation protocols for improving cognitive functions in patients with comorbid cognitive impairment. Specifically, the investigators will test the effectiveness of three rehabilitation protocols (digital-based cognitive rehabilitation combined with motor rehabilitation, paper-based cognitive rehabilitation combined with motor rehabilitation, and motor rehabilitation alone) by means of a set of multidimensional outcome measures. Secondary aims: - evaluating the enhancement of cognitive performance using various cognitive questionnaires categorized by cognitive domains. Additionally, the investigators will examine multidimensional variables such as motor skills, mood and anxiety levels, quality of life, patient adherence to treatment, the role of communication in patient management, caregiver burden, and the usability of digital devices (when utilized).
The study aims to investigate the efficacy and safety of intermittent theta burst stimulation (iTBS) guided by the personalized Brain Functional Sector (pBFS) technique in the treatment of patients with chronic post-stroke cognitive impairment.
Cognitive disorders are common after intensive care. Currently, their diagnosis is based on clinical tests. The investigators plan to study the relationship between different neurological blood biomarkers (cytokines, S100β protein, neuron specific enolase, total Tau protein and neurofilament light chain) and the occurrence of cognitive disorders during the three months following intensive care discharge.
The prevalence of dementia will double in the next three decades in the U.S.; effective treatment or prevention for dementia is urgently needed. The current exploratory project aims to evaluate and understand how the brain and cognition may improve after a 12-week intervention that combines brain training and aerobic exercise training to improve brain function, both in those with mild cognitive impairment (some with possible prodromal Alzheimer's disease) and with healthy aging. Findings from this pilot project will guide and refine the development of a future larger clinical trial that aligns with the goals of the National Alzheimer's Plan of Action (NAPA), especially regarding "Prevent and Effectively Treat Alzheimer's Disease (AD) by 2025.
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.
Dementia is the major cause of disability and dependency among older adults worldwide affecting memory, cognitive abilities and behavior, interfering with one's ability to perform daily lives activities. Although age is the strongest known risk factor for the onset of dementia, it is not a natural or inevitable consequence of aging. Dementia not only affects older people, since up to 9% of the cases appear before 65 years. The impact of dementia is highly important in financial terms also in human costs to countries, societies and individuals. Dementia is an umbrella term for several diseases, being Alzheimer's disease (AD) the most common form, contributing to 60-70% of cases. Other major forms include Lewy bodies Dementias (LBDs) and frontotemporal dementia (FTD). The role of the gastrointestinal microbiota in human brain development and function is an area of increasing interest and research. A large number of studies suggest that the gut microbiota can influence the brain, cognition and behavior of the patients, and also modulate brain plasticity, modifying brain chemistry via various mechanisms like neural, immune and endocrine Within these last two years some studies have showed differences in the microbiota of the AD patients from healthy controls. In this sense, increasing number of studies, most of them in animal models, support the notion that probiotics have significant benefit in maintaining homeostasis of the Central Nervous System. And recent studies try to replicate this finding in AD patients with controversial results. The main objective of DEM-BIOTA project is to improve the knowledge of the relationship between microbiota and dementia. DEM-BIOTA will explore the microbiota differences between dementias: AD, LBDs, that includes: Parkinson disease dementia (PDD) and Lewy Body Dementia (LBD) and FTD-behavioral variant, also in Mild Cognitive Impairment (MCI) to study the progression; in our context (Mediterranean diet and lifestyle) and characterize them in relation to neurocognitive and neuropsychiatric symptoms as well as patient functionality (dependency level). Moreover, the capacity of a probiotic compound in reverting or improving neurocognitive and neuropsychiatric symptoms and patient functionality in a sample of AD patients will be also studied.
Cognitive impairment has been reported up to 54 % after colorectal surgeries. Mechanical bowel cleansing means that a system called the second brain in the body, which includes a wide variety of genetic and neuronal structures, is damaged. 100 trillion microorganisms live in the human body. The largest contact area with the external environment in the body, is the gastrointestinal mucosa. Microorganisms in the gut contain 100 times more genes than the human genome. The GI mucosa contains more than 500 million neurons called the enteric nervous system. MBP is an application that disrupts the microbiota structure and causes dehydration and electrolyte imbalance. While the most serious indication for MBP is seen as infection and health of anastomosis, recent studies say that this is not the case, even that the deterioration of the microbiota content damages the mucosal barrier, predisposes to inflammation with the removal of beneficial microorganisms and impairs wound healing. 84 patients will be included in the study, divided into two groups. In each group, blood will be drawn to measure the levels of biomarkers determined before surgery and bowel cleansing, on the 15th postoperative day and on the 90th day. Simultaneously, psychometric tests will be performed to assess cognitive impairment.
