Active clinical trials for "Cognitive Dysfunction"

GSK1034702 is being developed for improving cognitive impairment in diseases such as Alzheimer's disease and schizophrenia. This study will be done in healthy men and women of no child beading potential to investigate repeated doses of the study medicine. The study will investigate the following questions, do repeated doses of the study medicine have any important side effects when taken by mouth? How much of the study medicine gets into the bloodstream, and how quickly does the body get rid of it? Does the study medicine affect memory, attention and problem-solving skills? What are the effects when the study medicine and dextromethorphan are taken together.

The purpose of this study is to determine whether brain oxygenation measured by cerebral oximeter has an impact on neurocognitive dysfunction.

The number of OEF/OIF veterans seeking care and rehabilitation services within the VA Health Care System is increasing rapidly. The cognitive effects of MTBI are clinically significant and can adversely affect a veteran's ability to reintegrate into civilian life, return to duty, succeed in competitive employment, or function independently. The primary product of the proposed study would be an empirically validated, manualized, cognitive rehabilitation intervention for OIF/OIF veterans with cognitive disorders. The group treatment modality has the virtue of efficiency and a manualized treatment approach would allow wide-ranging application throughout the VHA system. As such, the proposed study is likely to have a significant effect on the quality and effectiveness of rehabilitative services being offered to our returning soldiers with combat-related MTBI and cognitive impairment.

Major Depressive Disorder (MDD) is a severe and common psychiatric disorder. Although MDD primarily involves mood disturbances, patients also usually present alterations in cognitive function (attention, memory, executive functioning and psychomotor speed). Even though antidepressants are suggested in the literature to potentially improve cognitive dysfunction in patients with MDD to some degree, there is a lack of adequate and well-controlled studies to investigate this effect. This study will evaluate the efficacy, safety and tolerability of a new antidepressant Vortioxetine versus placebo on cognitive dysfunction in adult patients with MDD.

There is a mounting evidence of the modulation properties of the major catechin in green tea, epigallocatechin-3-gallate (EGCG), on dual specificity tyrosine-phosphorylation-regulated kinase 1A (DYRK1A) gene overexpression in the brains of DS mouse models.The aims are to investigate the clinical benefits and safety of EGCG administration in young adults with DS, to establish short-term EGCG effects (three months) on neurocognitive performance, and to determine the persistency or reversibility of EGCG related effects after three months of discontinued use.

This is an efficacy and safety study evaluating an experimental treatment for cognitive deficits in adults with schizophrenia.

The aim of this study is to evaluate the effects of Ginkgo Biloba Extract (GBE) in executive function-impaired Mild Cognitive Impairment (MCI) patients by assessing gait while walking alone as well as under differing dual-task conditions. The primary endpoint in the evaluation of GBE efficacy is gait speed. The secondary endpoint is cycle time variability under dual-task conditions.

A significant number of brain tumor patients who received radiation or chemotherapy have thinking problems as a result of their treatment. The purpose of this study is to find out if treatment with Aricept (donepezil) may improve some aspects of thinking abilities in patients with brain tumors who received radiation or chemotherapy. This research will also study whether persons having particular genes for a blood-borne substance called apolipoprotein E (APOE) are more likely to have thinking problems after radiation or chemotherapy treatment for their brain tumors. The findings of this study will help us find out whether Aricept can improve thinking abilities after cancer treatment, and whether some of the thinking difficulties may be in part related to having certain genes.

The overall goal of this project is to determine the feasibility of conducting a cognitive intervention for children with sickle cell disease.

A vitamin nutriceutical, Memory XL, has been shown to provide maintenance of cognitive status in mild, moderate, and severe Alzheimer's disease patients (2 publications by T. Shea). Because this nutriceutical is now patented by the Univ. of Mass., other trials at that institution may be considered a conflict of interest. Therefore, a study of its effects on Mild Cognitive Impairment (MCI) patients will be conducted by PI who is not affiliated with Univ. of Mass. or with Dr. Shea. The study hypothesis is: Memory XL will maintain or improve the cognitive and behavioral status of patients diagnosed with MCI during the year of participation in the study; normally, 10-25% of MCI patients convert to mild Alzheimer's dementia each year.
