Active clinical trials for "Cognitive Dysfunction"

Accumulating evidence indicates that inflammation is prominent both in the blood and central nervous system (CNS) of Alzheimer's disease (AD) patients. These data suggest that systemic inflammation plays a crucial role in the cause and effects of AD neuropathology. Capitalizing on the experience from a previous clinical trial with thalidomide, here, the investigators hypothesize that modulating both systemic and CNS inflammation via the pleiotropic immunomodulator lenalidomide is a putative therapeutic intervention for AD if administered at a proper time window during the course of the disease.

The purpose of this small, research study is to examine effectiveness of an at-home application of an experimental intervention, on thinking and memory in mild-moderate, closed-head, traumatic brain injury cases. The experimental intervention is light-emitting diode (LED) therapy, which is applied to the scalp and through the nose using a head frame device. Participants are expected to complete two, 5-week series of LED treatments, at home, 3 times a week. There will be a 1-month period between the two series. Each home treatment is 20 minutes. Participants will be trained to use the head frame device, in-office. The head frame device falls within the FDA category General Wellness, low-risk devices, and no medical claims are made. A two-hour paper and pencil testing (4 visits) and a one-hour MRI (3 visits) will be administered before and after each treatment series. Participants may be in the study for about 4 months. This study is supported by Vielight, Inc., Hayward, CA/ Toronto, Canada

This project explores the effects of specialized computer-based cognitive rehabilitation (CBCR) targeting executive functions in three groups of patients: Stroke, Cardiac Arrest and Parkinson's Disease. The effect of specialized CBCR is compared generally cognitively stimulating activities on a computer

The purpose of this study is to examine safety, feasibility, and the behavioral and brain effects of a non-invasive treatment, repetitive transcranial magnetic stimulation (rTMS), for Veterans with Parkinson's disease and mild impairments in their thinking. The hypothesis is that rTMS can improve thinking for people with Parkinson's disease who are experiencing mild problems with their thinking ability.

The purpose of this research study is to investigate the effectiveness of a memory enhancement technique in persons with a Traumatic Brian Injury (TBI). The study is designed to research how well this technique can help people with TBI improve their memory and their ability to function better in everyday life

This study will assess the effect of active postoperative temperature management and its effect on the cognitive function in patients following coronary artery bypass graft (CABG) surgery to determine if active postoperative temperature management to maintain normothermia reduces postoperative cognitive dysfunction (POCD) in this population. Additionally, the investigators will explore differences in temperature control variability by using temperature management wraps combined with acetaminophen vs. acetaminophen alone in a pilot arm.

Advancing Postmenopausal Preventive Therapy (APPT) is a randomized, double-blinded, placebo-controlled trial designed to determine the effects of tissue selective estrogen complex (TSEC) therapy on the progression of subclinical atherosclerosis and cognitive decline in 360 healthy postmenopausal women.

Decreased blood flow to the brain can cause decreased cognitive function. Carotid disease can result in decreased blood flow to the brain. The investigators seek to assess this relationship prospectively through performing a battery of neurocognitive assessments, collection of serum markers of inflammation, and through neuroimaging at two points before intervention (2 months and 1 month before stenting) and at two points after intervention (1 month and 2 months after intervention). The goal is to provide prospective evidence to identify the extent to which carotid stenosis and hypoperfusion of the brain results in diminished neurocognitive performance, and see if serum biomarkers before and after stenting correlate with these findings.

This is a 24-week randomized, double-blind, placebo-controlled parallel group design study involving Vascular cognitive impairment-no dementia (VCIND) patients to evaluate the efficacy and safety of oral NAC supplementation (2,400 mg daily) as an add-on therapy to improve cognitive function in patients undergoing cardiac rehabilitation (CR). The CR program consists of a harmonized aerobic and resistance training in a supervised group setting. Eligible patients will be randomized to receive NAC (four 600 mg capsules given as 2 capsules in the morning and 2 capsules in the evening) or matching placebo capsules. The initial NAC dosage will be 600mg/day (one 600mg capsule in the morning) for the first week, followed by 1,200 mg/day (one 600 mg capsule in the morning, one 600mg capsule in the evening) for the second week, followed by 1,800 mg/day (two 600mg capsules in the morning, one 600mg capsule in the evening) for third week, followed by 2,400mg/day (two 600mg capsules in the morning, two 600mg capsules in the evening) for the following 21 weeks.

Background: Dementia is a debilitating and devastating disease impacting the individuals, their families, and the health care system. According to the World Health Organization the dementia epidemic could overwhelm the global health care system and undermine social and economic development. Currently, no curative treatment for dementia exists despite immense research activity. The cognitive and functional impairment in dementia, especially Alzheimer's disease (AD), develop slowly decades before clinical signs emerge. This knowledge has led to the recognition of a prodromal period of mild cognitive impairment (MCI), between normal cognition and dementia. This is at present the earliest stage for intervention in dementia; even a short delay in dementia progression will have a large impact on global economy and health care. Objectives: In this clinical multicenter study, we aim to investigate the efficiency and cost-effectiveness of working memory training in MCI. To identify high responders to training analysis of genetic markers, relative's stress and craniospinal clearance will be performed. Participants and methods: This study is a blinded, randomized and controlled trail that will include 213 participants, diagnosed with MCI, included from five Norwegian Memory clinics in four health care regions. The groups will be randomized to either two training periods, one training period or active control. The intervention is computerized working memory training. Neuropsychological status, activities of daily living (ADL), and relative stress and quality of life will be assessed at baseline and 3, 6, 12 ,24 and 48 months after training. Structural MRI will be performed at baseline, and 3 and 6 months after training. For participants in the REACT MCI glymphatics substudy craniospinal clearance will be measured at baseline. A cost-utility analysis will be performed to evaluate if the working memory training is more cost-effective compared to the active control group in the MCI phase, taking a societal perspective.
