In people with Mild Cognitive Impairment (MCI) and Alzheimer's Disease (AD), reduced capacity for locomotor adaptation is a fundamental but poorly understood mechanism that can be a sensitive biomarker of cognitive-motor impairments. It is also an important therapeutic target for exercise-based interventions to improve walking function. The overall goal of this study is to understand the effects of MCI and AD on locomotor adaptation and walking function.
This descriptive, cross-sectional study will evaulate and fully characterize factors associated with cognitive dysfunction in Breast Cancer (BCS) and Colorectal Cancer (CRC) survivors that have cognitive concerns, and factors associated with psychoneurological symptom cluster in BCS and CRC survivors.
The purpose of the study is to evaluate the use of autologous Bone Marrow Derived Stem Cells (BMSC) as a means to improve cognitive impairment as occurs in Alzheimer's Disease and other dementias and to improve behavior and socialization issues which occur in adult Autism Spectrum Disorder. The use of Near Infrared Light, in conjunction with the use of BMSC, will also be assessed.
Childhood cancer survivors are at risk for accelerated aging due to the specific treatments they have received to cure their cancer. Several interventions, including exercise, cognitive training, and mindfulness practice, have been developed and studied for effectiveness among participants in the St. Jude Lifetime Cohort (SJLIFE) to mitigate these effects. The interventions offered thus far have not included two components at the same time. The purpose of this study is to determine whether or not adult cancer survivors enrolled in SJLIFE will participate in two interventions at the same time. The combined interventions will include exercise plus cognitive training or exercise plus mindfulness practice. Each intervention will be conducted over a 12-week period. Participants will also be asked to complete follow-up testing after the 12-week intervention period is completed. Primary Objectives • To determine the acceptability of a two-component intervention (exercise (EX) plus cognitive training (CT) or exercise (EX) plus mindfulness practice (MP)) among survivors of childhood cancer with either cognitive impairment or emotional distress. Hypotheses: * 45% of those approached for participation in each arm of this study will enroll on the study. * Among those who enroll, 70% will complete the follow-up testing at 12 weeks. * Among those who completed the follow-up testing, the mean attendance to the intervention sessions will be 70% on each of their two interventions. That is, they will complete 70% of exercise sessions and 70% of either cognitive training or mindfulness practice. * To identify barriers and facilitators to intervention adherence. Hypotheses: * Participants will identify features of the study processes that either facilitate or discourage adherence. * Participants will identify features of the intervention technology and intervention components that either facilitate or discourage adherence. * Participants will identify personal factors that facilitate or discourage adherence.
The goal of this clinical trial is to investigate the effect of two types of cognitive remediation training on real-world behavioral outcomes including substance use, institutional adjustment, and recidivism following release from prison. Each training type is designed to target one of two subtypes of antisocial criminal offenders, who are characterized by either: 1) Attention to context-based deficits, or 2) Affective cognitive control-based deficits. The main questions it aims to answer are: Does matching deficit type with targeted cognitive training improve outcomes (relative to mismatched training)? What are the functional brain mechanisms that underlie treatment change? Participants will: Be assigned to cognitive training that either does or does not match their deficit type. Complete six one-hour sessions of cognitive skills training. Complete pre and post-training behavioral tasks assessing self-regulation deficits. Complete structural MRI scans and functional MRI scans assessing cognitive control. Complete post-treatment follow-up assessments evaluating self-regulation, adjustment, and stressful life events, substance use and recidivism.
The purpose of this study is to evaluate the efficacy and safety of KarXT + KarX-EC for cognitive impairment in Alzheimer's Disease

The objective of this research study is to understand how Deep Brain Stimulation (DBS) targeting the subthalamic nucleus (STN) affects cognitive networks in the brain, potentially leading to cognitive decline in patients with Parkinson's Disease (PD). A total of 55 participants with PD who have undergone DBS surgery will be recruited from MUSC's Clinical DBS Program. Participants will attend two post-DBS visits: a 3-hour visit for consent, demographic, and cognitive assessments, and a 3-hour DBS-MRI visit to evaluate brain network connectivity with stimulation ON and OFF. These findings will help improve patient selection for surgery and optimize the selection of stimulation targets that minimize undesirable cognitive side effects.
In this research study we want to learn more about the effects of non-invasive brain stimulation on motivation, memory, and brain-network function in cognitively unimpaired older adults and individuals with preclinical Alzheimer's disease. This study will use a form of non-invasive brain stimulation called repetitive Transcranial Magnetic Stimulation (rTMS). rTMS will slightly alter activity in an area of your brain that controls cognition. Changes resulting from this stimulation will be measured with behavioral tests, as well as by taking brain images with Magnetic Resonance Imaging (MRI). Participants will come in for one baseline visit followed by 10 days of daily rTMS study visits (Monday through Friday) and an evaluation visit. Then, there will be a 2-week break. After this break, they will return for another baseline visit, an additional 10 days of rTMS, and a final evaluation visit.
The purpose of this research is to measure brain activity in individuals with mood disorders and memory problems using a simple, safe, and noninvasive method called functional near-infrared spectroscopy (fNIRS). By comparing brain activity across different groups and relating it to symptom severity, this study aims to improve our understanding of how these conditions affect the brain.
Researchers at Massachusetts General Hospital are looking to see if a program created to help improve thinking and memory can work for refugees and asylum seekers with traumatic brain injury (TBI). They're checking if this program is practical and if people find it helpful. The study will have two groups, and people will be assigned to a group by chance. One group will participate in the program and answer questionnaires before starting the program and then one month and three months after the end of the program. The other group will answer a questionnaire after they enroll, then one month and three months after enrollment. People in this second group will have the option to participate in the program after three months.
The goal of this clinical trial is to see if silent brain infarcts (SBIs), or stroke-like symptoms detectable during brain imaging, are a possible contributor to cognitive decline for patients diagnosed with spontaneous intracerebral hemorrhage (sICH), or blood clot in the brain. The main questions it aims to answer are * if SBIs in sICH are associated with a lower cognitive level and more rapid cognitive decline * if SBIs in sICH are associated with certain findings on brain imaging * if SBIs in sICH are associated with higher inflammation measured by certain blood tests Participants will undergo * cognitive testing during hospitalization, and at 3, 6 and 12 months after the sICH * Magnetic Resonance Imaging (MRI) of the brain during hospitalization and 12 months after the sICH * blood draws during hospitalization and at 3, 6 and 12 months after the sICH
Mild Cognitive Impairment (MCI) in older adults is linked to muscle loss (sarcopenia) and can lead to dementia, with pain further impacting cognitive and physical performance. Tai Chi, a mind-body exercise, is recommended for managing MCI as it supports cognitive function, mood, and physical health. The investigators' first goal is to characterize the correlation of heart rate variability and cortical activity on cognitive function and the psychosocial correlates of pain interference and social isolation on cognitive function at baseline and post-intervention (8 weeks of Tai Chi). The second goal is to explain the role of sarcopenia and obesity in the relationship between pain interference and cognitive function. The investigators also want to examine the index of the predictive capacity regarding sarcopenia and obesity on cognitive function outcomes.
Individuals with immune thrombocytopenia (ITP) frequently report difficulties with attention and memory. The main question this study seeks to answer is: Do patients with ITP have evidence of cognitive impairment as detected by a cognitive function test battery? To address this issue, participants will take a cognitive function test and complete surveys on quality of life, fatigue, depression, and cognitive symptoms. The primary aim of the study is to evaluate for the presence and extent of cognitive impairment in patients with ITP. The study will also assess whether cognitive impairment in ITP is associated with patient-reported impacts on quality of life, fatigue, mood, and cognitive symptoms as well as clinical characteristics such as ITP disease and treatment history.
This study is examining the effects of standard of care cancer treatment as well as a medication called Sildenafil, on the cancer associated fatigue, cognition and the gut microbiome.
This clinical trial evaluates the impact of a research intervention of virtually supervised exercise program (RISE) on cancer-related cognitive impairment (CRCI), physical activity in adolescent and young adult (AYA) brain tumor survivors. This clinical trial also evaluates the impact of RISE on the collection of microorganisms that exist in the intestines (gut microbiome). Up to 45% of AYA brain tumor survivors experience CRCI, including issues with attention and memory. CRCI can have a negative impact on education, independent living and can worsen long-term quality of life. Moderate-intensity levels of exercise, particularly aerobic and resistance training, have been shown to improve cognitive function. Additionally, exercise can change the composition and function of the gut microbiome, which may lead to improved cognitive function. Unfortunately, only about 50% of AYAs with cancer receive exercise information or meet the physical activity recommendations. Tailoring a virtually delivered exercise intervention to meet the unique needs of AYAs may improve access to exercise. Participating in the virtual home-based exercise intervention, RISE, may improve physical activity and cognitive impairment in AYA brain tumor survivors and may also help researchers understand the relationship of exercise on the gut microbiome and cognitive function.
The goal of this clinical trial is to test a 6-month, twice a week, moderate intensity exercise and coaching program (an in-person group and a distance group) for adults with mild-moderate cognitive impairments living in South Carolina. The main questions it aims to answer are: 1. Is the program practical to conduct, and it is acceptable and enjoyable? The hypothesis is that it will be possible to recruit participants, obtain the desired dosage of moderate intensity fitness and strength training twice a week. 2. Are their changes at 3-months and 6-months in endurance, mobility, cognitive function and perception of cognitive function? The hypotheses are that endurance, strength and mobility will improve and cognitive measures will not decline (remain the same or improve). Participants will exercise twice a week in-person with a coach or at a distance location with coaching support for six months.
The purpose of this study is to conduct a small-scale test of a goals-based program to help people to exercise more and learn what people like or don't like about the procedures. This program is being designed for individuals aged 45-65 from the Black community. Low levels of physical activity are related to health problems such as heart disease, diabetes, and cognitive decline. People of color are more negatively impacted by these conditions and have also historically been underrepresented by research seeking to increase physical activity. The investigators have developed this goals-based exercise promotion program with the help of a Black-led community-based organization (The Gyedi Project) and a Community Advisory Board made up of stakeholders in the Black community, and now the investigators are conducting a trial of its feasibility and acceptability.
The purpose of this study is to assess the feasibility of an at-home MMT treatment in patients with cognitive dysfunction related to PASC, and to collect data on safety and efficacy to inform the design of larger clinical studies. A prospective randomized controlled study of 30 participants with PASC and moderate to severe cognitive dysfunction. Total study duration will be 8 weeks, including 4 weeks of treatment and 4 weeks of untreated follow up.
The purpose of this study is to test whether a special memory training program, called CogMed, can help people with early memory problems. The Investigators want to see if this training improves memory and also helps reduce stress. The Investigators also want to see if CogMed results in changes to a blood biomarker called p-Tau 217, which possibly indicate Alzheimer's disease (AD).
Cognitive problems, like memory loss, are common after brain injuries like trauma or stroke. These problems make daily life harder, and the investigators don't yet know the best ways to help the brain recover. Scientists think that a process in the brain called long-term potentiation (LTP) is important for memory and learning. When LTP isn't working properly, it may cause problems with thinking and memory. But studying LTP in people is hard because it happens deep inside the brain. Our research uses a treatment called electroconvulsive therapy (ECT) to better understand LTP. ECT is a treatment for severe depression that works by causing a controlled seizure in the brain. While ECT often helps depression, it can temporarily cause memory and thinking problems, which usually improve over time. This makes ECT a good way to study how thinking and memory recover. The investigators will use a tool called electroencephalography (EEG) to measure brain activity during different stages of ECT treatment. EEG is a safe and non-invasive way to track changes in LTP. Specifically, the investigators will measure how the brain responds to visual signals using something called visual evoked potentials (VEPs). These signals can show how LTP is affected by ECT. The study's main goal is to track changes in LTP using VEPs during and after ECT. By studying these changes, the investigators hope to learn how ECT affects the brain and how it recovers. This could help improve treatments for brain injuries and other conditions that cause memory and thinking problems.
This randomized, placebo-controlled trial aims to assess the feasibility, acceptability, and preliminary efficacy of memantine and the University of Carolina (UNC)'s Get Real \& Heel cancer exercise program (MEM+EX) in addressing cancer-related cognitive impairment (CRCI) and underlying CRCI biomarkers. Ninety stage I-III breast cancer patients with mild cognitive difficulties during chemotherapy will be randomized into three groups: MEM+EX, memantine, or placebo. The study will evaluate recruitment, retention, adherence, acceptability, cognitive function, brain-derived neurotrophic factor (BDNF), inflammatory markers, and frailty at multiple time points.
Problems with walking and balance are common in older adults with mild cognitive impairment. Walking and balance problems limit independence and increase risk for injuries due to falls. The purpose of this research study is to test the effectiveness of training that combines moving and thinking tasks, referred to as Personalized cognitive integrated sensorimotor virtual reality (VR)/mixed reality (MR) training on walking and balance ability. The study will also help to understand the changes in thinking ability and brain activity as a result of this training in older adults with mild cognitive impairment. The study will evaluate the differences between two intervention groups (n=20 each): 1) personalized cognitive integrated sensorimotor VR/MR training (CM), and 3) standard of care (CTRL) on gait, balance, community ambulation, and cognitive functions, as well as underlying biomechanical and neurophysiological mechanisms to understand the changes due to CM.
Neuropsychiatric symptoms (NPS) refer to a range of mental and emotional issues that can be observed through how patients move, perform daily tasks, and express feelings on their faces. In this study, the investigators want to find ways to accurately and unobtrusively track these symptoms in people's homes over time. Our goals are to note when these symptoms happen, predict potential problems, and gather clear data to help doctors make accurate diagnoses. To do this, the investigators will first collect information from participants who have in-home sensors. the investigators will then use special computer programs that can recognize everyday activities and identify features that connect to scores from the Mild Behavioral Impairment Checklist (MBI-C). These scores will be compared to a questionnaire (NPIQ) filled out by caregivers or family members, along with any relevant information from doctors about the patients' symptoms. The investigators aim to see how these features can help differentiate between types of NPS, such as mood changes and agitation. Finally, the investigators will create a dashboard for doctors that summarizes the patterns of these symptoms in patients, making it easier to monitor and manage their mental health.
The goal of this study is to test a new way to improve sleep quality in persons living with mild cognitive impairment. The treatment combines a safe and gentle way to stimulate the brain, called transcranial magnetic stimulation, with a psychological treatment, called cognitive behavioral therapy for insomnia.
The goal of this study is to test a home-based and patient-tailored cognitive training intervention among gynecologic cancer patients who have completed chemotherapy and who have experienced cancer-related cognitive impairment.
Depression affects one-third of intensive care unit (ICU) survivors and represents a potentially modifiable target to slow cognitive decline and reduce the risk of Alzheimer's disease and related dementias (ADRD). Our multi-PI team proposes a two-arm RCT called ADEPT-ICU (Attenuating DEPression with Internet CBT to Slow Cognitive Decline in Older ICU Survivors), which will test the efficacy of an internet CBT intervention called Good Days Ahead (GDA) to reduce the burden of subjective cognitive decline (SCD) in older ICU survivors with moderate to severe depressive symptoms after ICU hospitalization.
Effective, clinically meaningful treatments are lacking for patients with mild cognitive impairment (MCI), which is associated with increased risk of transition to dementia. Cognitive training represents an important therapeutic strategy. In a previous study, crossword puzzles were found to be superior to computerized cognitive training on the primary cognitive outcome and function with decreased brain atrophy. Building on these findings, this study will evaluate and compare the impact of high dose crosswords (4 puzzles per week) to low dose crosswords (1 puzzle per week) and a health education control group on the cognition and function of participants.
Bio-Hermes-002 is a 120-day cross-sectional study that will result in a blood, CSF, retinal, digital, MRI, and PET brain imaging biomarker database that can be used to determine the primary objective. Digital biomarkers and blood-based biomarkers will be tested to determine whether a meaningful relationship exists between biomarkers alone or in combination with tau or amyloid brain pathology identified through PET images.
This is a phase 2a, randomized, double-blinded, placebo-controlled pilot clinical trial determining the impact of riluzole therapy on circulating brain derived neuropathic factor (BDNF) levels of breast cancer survivors with cancer related cognitive impairment.
