Active clinical trials for "Cognition Disorders"

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.

Atomoxetine is the only medication that is currently approved by the FDA for the treatment of attention deficit hyperactivity disorder in adults. It has gained recent interest as an alternative medication for treating attentional problems related to traumatic brain injury (TBI), but it's effectiveness in this population has not been studied. There are a number of advantages of Atomoxetine over traditional neuro-stimulant medications currently used for attentional disorders after traumatic brain injury. This study will use a randomized double-blind placebo-controlled crossover design to investigate the efficacy of atomoxetine to improve attention, behavioral function, and depression in adults with TBI

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

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 study will compare the effectiveness of Problem Solving Therapy and Brief Supportive Therapy in treating elderly patients with major depression and thought problems.

Delirium is associated with increased risk of death, prolonged stay, higher cost of care, and likely long-term brain deficits in survivors. This form of brain dysfunction occurs in intensive care unit (ICU) patients in epidemic proportions, and the scope of this problem is likely to worsen in upcoming years due to the aging of our population and increased utilization of the ICU. Currently, delirium goes unrecognized and untreated in the vast majority of circumstances in the ICU unless the patient presents with hyperactive delirium and agitation. In the latter circumstance, a commonly used typical antipsychotic called haloperidol is considered the principal agent for treating delirium based largely on anecdotal evidence to support its usefulness, though no placebo controlled trials exist. There are no FDA approved medications for delirium. The atypical antipsychotics provide a promising alternative for the treatment of delirium due to their enhanced beneficial effects on positive (agitated) and negative (quiet) symptoms proven in mania and schizophrenia, reduced risk for side effects common to haloperidol such as extrapyramidal symptomatology, and less potentially lethal heart rhythm disturbances. It is imperative that well-designed phase II studies to determine proof of principle be conducted. A pilot study of feasibility to begin assessing the role of antipsychotics in the management of ICU delirium.

The purpose of this study is to: To examine wether adjunctive atomoxetine is more effective thank placebo for neuropsychological measures of reaction time, motor speed, psychomotor speed, sustained attention, learning and memory, working memory, and executive functioning. To determine the effect size of atomoxetine on these neuropsychological measures for follow-up studies. To determine if atomoxetine has short-term benefits for improving weight gain and other metabolic abnormalities associated with antipsychotics.

The purpose of this study is to compare pictures of the brain of HIV-infected people with memory problems before and after treatment with selegiline. Selegiline is the study drug received through A5090. HIV patients generally develop memory problems late in the disease. This will be examined using noninvasive proton magnetic resonance spectroscopy (1H-MRS). The effect of the drug selegiline on memory problems also will be examined.

To evaluate the chemical efficacy and safety of intranasally administered peptide T on neurocognitive function in HIV seropositive individuals. Previous studies have shown that treatment with peptide T can result in cognitive improvement in HIV-infected patients. Patients are randomized to receive either peptide T or placebo for the first 6 months. All patients then receive open-label peptide T for approximately 6 additional months. Neuropsychologic tests are used to determine drug effects.

This phase IIIb trial is a prospective, randomized, double-blind, placebo-controlled, 36-month study comparing the length of time of progression from mild cognitive impairment (MCI) to a clinical diagnosis of Alzheimer's disease (AD) in subjects taking Exelon vs. placebo. Exelon is currently under review with the U.S. Food and Drug Administration as a treatment for Alzheimer's disease. The drug has been cleared for marketing in more than 40 countries for Alzheimer's disease to date, including all 15 member states of the European Union, New Zealand, Argentina, Brazil and Mexico. Each subject with MCI will be randomly assigned to treatment with either Exelon or placebo. Subjects assigned to Exelon will receive 1.5 to 6.0 mg bid (twice daily) (3.0 to 12 mg/day) for the majority of the study. At every regular visit scheduled every three months, patients will be given basic efficacy and safety assessments. These assessments will include evaluation of adverse events, vital signs, activities of daily living, and clinical staging scales to determine if the subject may have converted to dementia.
