Active clinical trials for "Cognition Disorders"

The proposed randomized controlled trial will evaluate the effects of treadmill training augmented with virtual reality on fall risk. 300 older adults with a history of falls will be recruited to participate in this study. This will include older adults (n=100), patients with mild cognitive impairment (MCI) (n=100), and patients with Parkinson's disease (PD)(n=100). Subjects will be randomly assigned to the intervention group (treadmill training with virtual reality) or to the active-control group (treadmill training without virtual reality). Each person will participate in a training program set in an outpatient setting 3 times per week for 6 weeks. Assessments will take place before, after, and 1 month and 6 months after the completion of the training.

This is a study of the effects of tDCS on smoking, craving for cigarettes, cognition, and psychiatric symptoms in schizophrenic patients who are current smokers or have a history of regular cigarette smoking. It assesses smoking with CO monitoring, nicotine and nicotine levels, and craving with QSU scale and response to craving slides. Cognition is measured by MCCB, symptoms are measured by PANSS and hallucination scale. This is a double-blind sham-controlled study with active tDCS 2ma or 20 minutes over 5 days, and sham tDCS for 40 seconds on each sham occasion.

This study is investigating the efficacy of computer-based cognitive exercises as a means of cognitive remediation in patients with Multiple Sclerosis (MS) who are beginning the disease modifying pharmacotherapy Gileyna.

The objective of this study is to evaluate the safety, tolerability, and efficacy of two dose regimens of PF-3463275 compared with placebo added to ongoing atypical antipsychotic therapy for cognitive deficits in subjects with chronic symptoms of schizophrenia.

This is a First Time in Human Study to assess the safety, tolerability and pharmacokinetics of single doses of GSK1034702 in healthy subjects. It will be a single-blind, randomized, placebo-controlled, single oral dose, dose-rising, cross-over study in healthy male and female (of non-child bearing potential) subjects. Subjects will be randomized into cohorts of 10 subjects and cohorts will be recruited until the pre-defined safety or PK stopping limits are reached. Each subject will receive placebo and up to 4 doses of GSK1034702 in a randomized sequence on 5 separate study occasions.

The purpose of this study is to evaluate the effectiveness of donepezil (Aricept) for the treatment of mild cognitive impairment (MCI) in elderly adults. This study will also determine whether adding ginkgo biloba extract (GBE) enhances the effects of donepezil.

The purpose of this follow-up study is to assess the long-term safety and tolerability of galantamine in individuals with mild cognitive impairment who participated in a previous study with galantamine

To study the safety, toxicology, and activity of Peptide T (D-Ala-1-peptide-T-amide) in humans and to find out more about the ability of peptide T to prevent, halt, and/or reverse AIDS-associated immunologic disturbances. Recent information suggests that the central nervous system (CNS) is often impaired in HIV-infected individuals. The dysfunction of the CNS may be either a direct or an indirect result of HIV infection. One method to prevent HIV infection is to block entry of the virus into the cells of the body. Peptide T shows laboratory evidence of blocking the entrance of HIV into cells that are susceptible to HIV infection. Studies that have been done indicate that peptide T is nontoxic in the doses that are used in this study. AIDS patients with minimal (group 1) or moderate (group 2) cognitive dysfunction (mental impairment) receive an increasing schedule of three dosage levels of peptide T. All patients receive an intravenous (IV) dose of peptide T for 10 days followed by the intermediate dose and then the highest dose, each intravenously for 10 days. Following successful completion of 3 IV doses, four patients participate in an intranasal pharmacokinetic (blood level study) dosage trial of 3 doses (different from IV) of peptide T once for each of 3 successive days. Follow-up continues for up to 1 year.

This is a First-in-Human, Randomized, Placebo-controlled, Single Ascending Oral Dose Study of SDI-118 in Healthy Male Subjects including Receptor Occupancy Measurements after Single Dose of SDI-118 and an Assessment of Food Effect.

This trial attempts to evaluate the effects of intensive transcranial direct-current stimulation (tDCS) on improving cognition in schizophrenia patients and changes in resting state brain network connectivity, especially increasing connectivity in the tasks related network, and increasing activation the DLPFC in a working memory task. Half of the participants will be randomized to tDCS group, while the other half will be randomized to receive sham tDCS.
