Cognitive Impairment Clinical Trials

The proposed research is a randomized crossover trial designed to assess changes in postprandial cognitive function and the gut-brain axis in adults with subjective cognitive complaints who consume 1 study snack per day for 1 week. Read Less

The purpose of this prospectively enrolling trial is to assess long-term cognitive outcomes of patients undergoing surgery for resection of a meningioma associated with the frontal and temporal lobes. Read Less

Positron Emission Tomography (PET) is a procedure that uses a special type of machine to take pictures of the inside of the body after a radioactive drug is administered. The radioactive drug that is used for this study may be an FDA approved imaging drug or may be used as an investigational imaging drug as part of another study for which participants are taking part. PET using various radiotracers is useful for the diagnosis of various diseases, including cancer, brain diseases, infection, and heart or lung disease. The purpose of this study is to test a research PET machine called the PennPET Explorer long-axial field-of-view scanner. This research PET machine can image a larger section of the body than the current clinical PET scanners, allowing most of the body to be imaged at one time. This scanner is still an investigational device and is being tested in this study to collect more information about how best to use this type of whole body scanner. Read Less

The goal of this interventional study is to determine the impact of high potency THC product use on cognitive function of young adults aged 21-25. The main question it aims to answer is: will cannabis users who switch to less potent THC products demonstrate improved cognitive function compared to baseline? Other questions this study aims to answer include: * Can researchers accurately assess THC consumption among frequent cannabis users? * Can researchers effectively incentivize cannabis users to use less potent THC products? * Do genetic variations in THC metabolism impact urinary THC excretion? * Do genetic variations in THC metabolism impact cognitive performance in cannabis users? * Are quantitative urinary THC values predictive of cognitive impairment? * How can researchers use research findings to inform harm reduction practices for people who use cannabis? Participants will submit blood and urine samples and be incentivized to use less potent THC products. Read Less

More than 60% of intensive care unit (ICU) patients are adults ages 60 and older, who are at high risk for ICU-acquired cognitive impairment. After ICU discharge, ICU survivors often experience sleep disturbances and inactivity, and almost 80% of ICU patients experience disturbances in circadian rhythm, which may affect cognitive function. Understanding the optimal, chronotherapeutic timing of cognitive interventions is crucial to promote circadian realignment and cognitive function, and may improve intervention feasibility, acceptability, and efficacy. Specific Aim 1 will determine feasibility, acceptability, and preliminary effect sizes for: 1) a morning session of a computerized cognitive training intervention \[COG\]; and 2) a late afternoon/early evening session of the COG intervention; compared to 3) standard inpatient care/usual care \[UC\]. Specific Aim 2 will examine circadian rhythm parameters to determine the optimal timing of the daily COG intervention. Exploratory Aim 3 will explore if the effects of the COG intervention on cognitive function are mediated by daytime activity, and explore if selected biological and clinical factors moderate intervention effects on cognitive function.

The goal of this study is to assess any post operative cognitive changes following benzodiazepine administration during cataract surgery. The investigators will compare effects of Midazolam vs. Remimazolam on cognition at the time of discharge from the post operative care unit and the next day following surgery. Cognitive changes will be assessed by administration of Montreal Cognitive Assessment (MoCA). Participants will: 1. Complete MoCA testing prior to surgery 2. Randomize in either Midazolam or study drug Remimazolam 3. Complete MoCA testing after surgery at the time of discharge in the post anesthesia care unit and the next day of surgery at the time of post operative surgical visit. 4. Complete Patient Satisfaction Survey at the time of discharge from the Post Anesthesia Care Unit (PACU) Read Less

This is a human clinical study involving the isolation of autologous bone marrow derived stem cells (BMSC) and transfer to the vascular system and inferior 1/3 of the nasal passages in order to determine if such a treatment will provide improvement in neurologic function for patients with certain neurologic conditions. http://mdstemcells.com/nest/ Read Less

The purpose of this study is to see whether programs that include both a patient and their spouse or a patient and family caregiver (known as a dyad) are helpful for families in which one member of the dyad has cancer and mild memory difficulties and/or concerns. Participant and their spouse or participant and their family caregiver will have six, 60-minute video-conference sessions which will be scheduled at their convenience. The investigator will loan participants a tablet computer (iPad) to use for videoconferencing and train the participant in its use. Participant and their spouse or participant and their family caregiver will complete three assessments - one before starting the sessions, one after the sixth session, and one after 1 month. Each assessment will include surveys, which the participant will complete separately from their spouse or family caregiver. For most people, it will take upwards of 2 - 4 months to complete this study Read Less

Cognitive impairment related to dementia is frequently under-diagnosed in primary care settings. This problem is more prevalent in health disparities populations. The investigators developed the 5-Cog brief cognitive assessment that is simple to use, standardized, takes \<5 minutes, does not require informants, and accounts for major technical, cultural, and logistical barriers of current assessments. The investigators propose a hybrid Type 1 effectiveness-implementation design in real-world settings to adapt and test the effectiveness of the 5-Cog paradigm to increase detection of cognitive impairment care in older adults presenting with cognitive concerns. The study aim is to evaluate, using a pragmatic cluster-randomized trial design, the effectiveness of the 5-Cog paradigm to increase 'incident cognitive impairment' detection (new MCI and dementia diagnoses) relative to enhanced usual care in 6,600 older patients presenting with cognitive concerns in 22 primary care clinics in Bronx and Indiana. As diagnosis without action will not improve patient care, 'improved dementia care' will be examined as a secondary outcome. Results will also be examined in NIH designated health disparity populations including underserved minority and socio-economically challenged populations. Read Less

As our population ages, more older adults face motor-cognitive declines, increasing their risk of falls and fear of falling. Exercise is an effective way to maintain cognitive function, as supported by recent studies. However, those with poor motor and cognitive abilities often struggle to visit rehabilitation centers, leading to high dropout rates and low adherence to unsupervised programs. A remote exercise program tailored for individuals with cognitive impairments is urgently needed to preserve cognitive function, promote independent living, and reduce related costs. Researchers aim to develop an in-home system for adults with mild cognitive issues or dementia, designed to improve balance and cognition while being remotely supervised through telemedicine.
