Active clinical trials for "Cognitive Dysfunction"

This study sought to investigate the changes in attention in older adults with mild cognitive impairment after Multi-domain Attention Training .

A Phase 1 study designed to evaluate imaging characteristics of flortaucipir in the preclinical, prodromal and dementia phases of Alzheimer's disease.

The overarching aim is to develop and deploy a multidomain intervention delivered on a mobile application to help older adults reduce their risk for dementia by improving a set of modifiable lifestyle risk factors associated with cognitive decline/dementia. The targeted domains are physical activity, diet, and cognitively stimulating activity. This registration concerns the Proof-of-concept study which will examine if individual parts of the intervention program achieve a clinically significant degree of change in the targeted behavioral risk outcomes. It is expected that following the program, at least 50% of participants will show evidence of a clinically significant degree of change in the behavioral risk outcome targeted by the intervention, when compared to baseline.

Neurological dysfunction continues to be one of the complications of considerable concern in patients undergoing cardiac surgery. It was previously reported in the literature, that cerebral oxygen desaturation during cardiac surgery was associated with an increased incidence of cognitive impairment. This study aims to determine whether continuous monitoring of cerebral oximetry improves the neurocognitive outcome in coronary artery bypass surgery when associated with predetermined intervention protocol to optimize cerebral oxygenation.

The study investigates the incidence of remote ischemic conditioning in mild cognitive impairment and dementia patients

The purpose of this study is to improve cognitive dysfunction following chemotherapy, the investigators investigated to see whether a cognitive training for memory and concentration skills can improve cognitive performance in patients following cancer treatment.

The purpose of this study is to see if a drug called lidocaine prevents cognitive injury (a decline in mental abilities) after heart surgery. Lidocaine is currently FDA approved and is commonly used for treating some heart rhythm disorders and for regional anesthesia (blocking nerves). The investigators are enrolling subjects in this research project to see if lidocaine will reduce the high incidence of cognitive injury seen after heart surgery. As part of this study, the investigators will also evaluate the relationship between cognitive injury and genetic makeup and the chemical changes in the subjects blood during and after surgery.

The goal of this pilot work was to determine if the cognitive dysfunction accommodation strategies help patients retain/utilize more HIV prevention information and increase PrEP adherence. Fifty people who inject drugs (PWID) were prescribed PrEP and randomized to one of two conditions, Twenty-five PWID participated in a standard HIV prevention session and 25 other PWID participated in a HIV prevention session with the included accommodation strategies. At recruitment participants were asked to provide self-report of the screening form and cognitive functioning. The intervention consisted of a total of 5 sessions: 1 meeting to gain baseline information of participants and 4 intervention sessions. Participants completed the consent form, demographics, skills assessment, drug use behavior assessment, and HIV risk behavior assessment at the pre-interview meeting. Participants completed PrEP uptake assessments and skills assessments immediately following the intervention to compare the pre/post results between the two groups. All participants also completed an acceptability rating to help researchers determine the acceptability of the accommodation strategies used, at the end of the 4th session. The objective was to determine if the proposed accommodation strategies are feasible and efficacious at improving HIV prevention outcomes, including knowledge and skills. Information gleaned from this process will be used to refine the intervention approach for future testing and implementation.

The purpose of the research study is to investigate whether the extent and severity of lesions in the brain as measured by special MRI techniques can distinguish between Multiple Sclerosis (MS) patients with or without memory impairment and also between MS patients and age matched healthy controls.

This study will investigate the performance of physician readers trained to read florbetapir-PET scans using electronic media training.
