NCT07486141
The purpose of this study is to investigate the effects of Vitamin D3 combined with Folic Acid on mild cognitive impairment (MCI). Participants aged 50 to 70 years with MCI will be randomly assigned to three groups: a low-dose Vitamin D3 plus Folic Acid group, a high-dose Vitamin D3 plus Folic Acid group, and a placebo group. The intervention will last for 6 months. The main goal is to observe whether this nutritional intervention can improve or delay the decline of cognitive function.
NCT07474038
Mild cognitive impairment (MCI) is associated with increased risk of progression to dementia, highlighting the need for accessible interventions to support cognitive health. This randomized controlled trial will evaluate the safety and efficacy of a 12-month artificial intelligence (AI)-supported cognitive rehabilitation program for older adults with MCI. Participants will be recruited from an existing research study conducted within Kaiser Permanente Southern California and randomized 1:1 to either (1) AI-supported cognitive rehabilitation or (2) usual care alone. The intervention combines clinician-delivered telehealth cognitive rehabilitation sessions with daily AI-guided cognitive exercises and education. The primary outcome is change in global cognition at 6 months measured by the Montreal Cognitive Assessment (MoCA)-BLIND. Secondary outcomes at 6 and 12 months include additional measures of cognition, subjective memory, goal attainment, mood, and loneliness. Exploratory outcomes include engagement with the AI intervention and health-related behavioral outcomes derived from electronic health record data. Participant safety will be monitored throughout the study through adverse event tracking, review of AI interactions for safety concerns, and predefined procedures for responding to psychological or clinical risk. This study will determine whether integrating AI-guided cognitive exercises with clinician-delivered rehabilitation improves cognitive and related outcomes in older adults with MCI compared to usual care.
NCT04294888
The purpose of this study is to assess the effects of non-invasive brain stimulation on memory in cognitively unimpaired older adults and in patients amnestic mild cognitive impairment (aMCI) due to Alzheimer's disease (AD). This study will use repetitive Transcranial Magnetic Stimulation (rTMS) to stimulate nodes of the Default Mode Network (DMN)- which is thought to support episodic memory and to be affected by Alzheimer's pathology. We will use functional connectivity MRI (fcMRI) to assess changes in functional network architecture following the stimulation. We will also assess putative cognitive improvements resulting from the stimulation by in-depth memory testing.
NCT07220668
Falls and fall-related injuries are significant public health issues for adults 65 years of age and older. Over a third of older adults (OA) fall each year and 10-20% of falls result in serious injuries such as fractures and head trauma. The annual direct medical costs in the US as a result of falls are estimated to exceed $50 billion, and this estimate does not include the indirect costs of disability, dependence, and decreased quality of life. This project targets community dwelling OA with mild cognitive impairment (MCI). MCI is a leading risk factor for falls in OA. Approximately 15%-20% of OA have MCI, and over 60% of OA with MCI fall annually - two to three times the rate of those without cognitive impairment. We have developed and pilot-tested an innovative technology-supported intervention called Sense4Safety to 1) identify escalating risk for falls real-time through in-home passive sensor monitoring; 2) employ machine learning to inform individualized alerts for fall risk; and 3) link 'at risk' older adults with a coach who will guide them in implementing evidence-based individualized plans to reduce fall-risk. The purpose of this study is to assess the effectiveness of Sense4Safety in reducing fall risk with a randomized clinical trial, and understand implementation factors to improve the scalability of Sense4Safety in diverse community settings.
NCT06154174
The goal of this clinical trial is to test adding choline to ready-to-use therapeutic food (RUTF) in children with severe acute malnutrition (SAM) in Malawi. The main question it aims to answer is: \- Will the addition of a 500mg daily dose of choline to RUTF during treatment for SAM improve cognitive development among 6-59-month-old Malawian children compared with standard RUTF without added choline?
NCT07446478
This study aims to evaluate the efficacy and safety of TIS targeting the hippocampus in ameliorating cognitive impairment associated with schizophrenia (CIAS). Participants will receive TIS twice a day for 2 weeks. Their clinical data, including the baseline clinical symptom scale score, cognitive function, and MRI data, will be collected at baseline and at the end of the 2-week intervention.
NCT04123314
This open-label pilot study examines whether the hallucinogenic drug, psilocybin, given under supportive conditions, is safe and effective for depression in people with Mild Cognitive Impairment (MCI) or early Alzheimer's Disease (AD). This study will also assess whether psilocybin may improve quality of life in those individuals.
NCT07366346
The goal of this clinical trial is to develop a five-week virtual cognitive training intervention for people with Mild Cognitive Impairment (MCI) based off an existing eight-week intervention. The main question it aims to answer is: • Is five weeks of training as good as eight weeks in improving cognition, quality of life, daily functioning, and mood, and in reducing caregiver burden? Researchers will compare five weeks of cognitive training to eight weeks of training to see if the shorter version is as effective as the full training. Participants will complete all activities virtually: * Complete a screening visit with a study partner (typically a family member, roommate, or close friend) to determine eligibility to participate in the study * Complete some tests of memory and thinking and some questionnaires * Attend weekly two-hour group cognitive training sessions with a trained group leader, for five or eight weeks * Redo the questionnaires and tests of memory and thinking immediately after completing the training, and three months after completing the training
NCT03741751
The proposed project aims to establish the feasibility and tolerability of delivering repetitive transcranial magnetic stimulant (rTMS) combined with computerized cognitive training in patients with Schizophrenia or Schizoaffective Disorder and cognitive difficulties. The investigators will conduct a 2 week randomized controlled trial study evaluating computerized cognitive training combined with either active or sham rTMS on cognitive and functional outcomes in adults with Schizophrenia or Schizoaffective Disorder.
NCT06780917
The goal of this observational study is to validate the Creyos online cognitive assessment platform in individuals with mild cognitive impairment, or remitted major depressive disorder. The main objectives of this research are: 1. To confirm the feasibility of administering the Creyos cognitive battery to older adults with Mild Cognitive Impairment MCI) or Major Depressive Disorder in remission (rMDD). 2. To determine whether the Creyos battery can detect changes in cognition that are predictive of changes on paper-and-pencil neuropsychological testing ("gold standard") over up to five years. Participants will complete both in-person neuropsychological testing yearly as well as the Creyos online battery quarterly for up to 5 years, to allow us to compare performance on these two batteries over time.
NCT07243600
This study is a validation study to evaluate efficacy of two neuroplasticity-based, computerized cognitive training programs to improve neurological and neuropsychological health in older adults with mild cognitive impairment (MCI).
NCT04769310
Demonstrating the pathophysiological link between Left Atrial (LA) and Left Atrial Appendage (LAA) pathology and embolic strokes in non-Atrial Fibrillation (AF) individuals represents a major advance in stroke prevention strategies. Instead of relying on non-specific criteria for stroke risk assessment, the investigators propose to identify individuals with high-risk of embolic stroke using imaging criteria that reflect the underlying pathophysiology of embolic stroke of cardiac origin. the investigators can therefore lay the groundwork for future anticoagulation strategies for stroke prevention beyond AF.
NCT07449117
The purpose of this study is to investigate the immediate effects of non-invasive temporal interference stimulation (TIS) targeting the striatum on sentence processing and brain connectivity in patients with neurodegenerative diseases.
NCT05896189
This Phase III trial will examine the efficacy of computerized cognitive training methods on perceived cognitive impairment in breast cancer survivors.
NCT07442448
The goal of this clinical trial is to evaluate the impact of Finerenone on myocardial remodeling in patients with diabetic kidney disease (DKD) and heart failure with a left ventricular ejection fraction (LVEF) ≥ 40%. The main questions it aims to answer are: 1. Does 6-month treatment with Finerenone significantly reduce myocardial fat infiltration (measured by MR Spectroscopy) and myocardial fibrosis (measured by extracellular volume fraction on CMR)? 2. Does Finerenone improve global left ventricular longitudinal systolic strain (GLS) and other structural remodeling indices in this patient population? Researchers will compare cardiac imaging parameters after 6 months of treatment to baseline values to see if Finerenone effectively reverses or slows down pathological cardiac changes. Participants will: 1. Take Finerenone (Kerendia) 10 mg or 20 mg orally once daily for a total of 6 months. 2. Undergo advanced cardiac imaging, including Cardiac Magnetic Resonance (CMR) and MR Spectroscopy (MRS), at the beginning of the study and after 6 months of treatment. 3. Receive regular clinical follow-up and blood tests to monitor safety (such as potassium levels and kidney function) and treatment efficacy.
NCT05830903
Establish a novel vocational training program and test its validity in a pilot study.
NCT05978804
The primary objective of this research is to evaluate the effects of non-invasive brain stimulation and computerized cognitive training on executive functioning in individuals with Primary Progressive Aphasia (PPA), mild cognitive impairment (MCI), or dementia. In this study, investigators will use transcranial direct current stimulation (tDCS) to stimulate the left dorsolateral prefrontal cortex (DLPFC). Previous studies have demonstrated that tDCS over the DLPFC led to improvements in attention deficit caused by stroke, Parkinson's Disease, and major depression as well as language deficits caused by neurodegenerative conditions such as primary progressive aphasia or mild cognitive impairment. The investigators seek to expand on this literature by investigating how anodal tDCS paired with and without cognitive training will impact executive functioning in PPA with Frontotemporal Dementia or Alzheimer's Disease pathology and Mild Cognitive Impairment/Alzheimer's Disease (e.g. shifting, updating, monitoring, and manipulation).
NCT06041152
The goal of this pilot, exploratory, clinical trial is to investigate the effects of psilocybin on synaptic vesicular density (SVD) as measured by the positron emission tomography (PET) radiotracer, 18F-SynVesT-1, in participants with amnestic Mild Cognitive Impairment (aMCI) and healthy participants. The investigators hypothesize that SVD levels in the brain will be higher following the ingestion of psilocybin in comparison to placebo, and that increases in SVD will be associated with improvements in cognition. 10 participants (6 with aMCI, and 4 sex and age matched healthy volunteers) will: * Be randomized to receive either: 1. Two 25 mg macrodoses of psilocybin separated by 1 week. 2. Two placebo doses separated by 1 week. * Receive a baseline 18F-SynVesT-1 PET scan, clinical, and neuropsychological assessments. * Receive a 18F-SynVesT-1 PET scan one week after the last dose of treatment. * Depending on available funds, receive a third PET scan at any time within 4 weeks of the screening visit to quantify tauopathy with the \[18F\]T807 radiotracer. * Receive clinical and neuropsychological testing 1, 4, and 12 weeks after the last treatment. Researchers will compare placebo vs. experimental groups to see if psilocybin will increase SVD, and if increases in SVD are associated with cognitive improvements.
NCT06542458
Overall, this study's primary aim is to establish a prospective, longitudinal, observational cohort study of older adults at risk for dementia from under-resourced/underrepresented communities. More specifically, older adults diagnosed with subjective cognitive decline (SCD) or Mild Cognitive Impairment (MCI) during clinical care offered via the Tele-Cog clinic would be recruited for more comprehensive data collection to characterize the clinical presentation and course of illness over multiple timepoints spread out longitudinally.
