Active clinical trials for "Cognitive Dysfunction"

In this proposal, we will examine processing speed training (PST) as a potential intervention to reduce the risk of developing long-term cognitive impairment after a delirium episode.

Sectorisation of the German health care system causes inefficient treatment, especially in elderly with cognitive impairments. At time of transition from hospitals into primary care it lacks, among others, coordination of post-operative care or timely communication between healthcare providers. This results in deterioration of disease and comorbidities, higher rates of re-admission and institutionalizations. Models of collaborative care have shown their efficacy in primary care. Main goal is to test the effectiveness of Dementia Care Management (DCM) for people with cognitive impairment to improve treatment and care across the in-hospital and primary care sector. The study design is a complex, longitudinal, multisite randomized controlled trial. It was designed to treat a hospital-based epidemiological cohort of people above the age of 70 with an adaption of DCM, a treatment proven to be effective in primary care, to the discharge setting. As part of this, specifically trained study staff will develop, implement and monitor a treatment and care plan, based on comprehensive assessments during the hospital stay, recommendations at discharge and unmet needs at home. For the 3 months after discharge study staff will coordinate treatment and care in close cooperation with the discharging hospital, treating physician and other care providers. Expected results from the study should facilitate the implementation of intersectoral care management systematically on a large scale. Thus, the benefits shown in the trial would be available to a larger population. Results will not be limited to PCI, but rather to any people transitioning between the in-hospital and the primary care sector. Thus, the benefits would be available to elderly people in general.

Individuals with mild cognitive impairment (MCI) and subjective cognitive decline (SCD) have greater risk of developing dementia. Cognitive intervention is a topic of great interest in individuals with MCI and SCD for the purpose of preventing or delaying the occurrence of dementia. There are many different types of cognitive interventions, which aim to positively impact the cognitive functioning of an individual and have been classified as cognitive stimulation, cognitive training, and cognitive rehabilitation. However, most studies used neuropsychological cognitive measures for outcome evaluation. The impact of cognitive interventions on daily functional performance among individuals with MCI and SCD were rarely explored. In addition, cognitive training focusing on specific cognitive outcomes is suspected to have limited far transfer to everyday measures. Therefore, a multicomponent intervention which integrates several types of intervention is recommended to reach the maximum impact on daily function. The purposes of this study are to examine the effects of a multicomponent cognitive intervention on cognitive and daily functional outcomes in individuals with MCI and SCD, and to compare the effects between the two groups. In addition, the investigators will also investigate whether the demographic (e.g., age and educational level, etc.) and clinical variables (e.g., duration of cognitive complains, level of depression and baseline cognitive function, etc.) may affect the outcomes of cognitive intervention.

The purpose of this study is to assess the effects of non-invasive brain stimulation on memory and language ability in patients with two phenotypic variations of underlying Alzheimer disease pathology: amnestic mild cognitive impairment (aMCI) and logopenic variant of primary progressive aphasia (lvPPA). This study will use repetitive Transcranial Magnetic Stimulation (rTMS) to stimulate nodes of networks that are thought to be affected in these two conditions. Specifically, a node of the Default Mode Network (DMN)-the angular gyrus (AG)-will be stimulated in aMCI patients; and a node of the language network-the posterior inferior frontal gyrus (pIFG) will be stimulated in patients with lvPPA. We will use functional connectivity MRI (fcMRI) to assess changes in functional network architecture following the stimulation. We will also assess putative cognitive improvements resulting from the stimulation by in-depth language testing in lvPPA patients and in-depth memory testing in aMCI patients.

This study evaluates a novel arm restraint compared with traditional soft wrist restraints in older critically ill patients. The primary outcome is upper extremity mobility measured by actigraphy, and secondary outcomes include sedation, agitation, satisfaction, and acceptability.

Cancer survival rates have increased dramatically in recent years. However, many survivors report cognitive decline following treatment, which significantly impairs their quality of life. Online cognitive training programs have shown promise in improving cognitive functions in cancer survivors, but most studies report limited impact of training on everyday function. A complementary treatment approach is functional treatment delivered by occupational therapists, which directly targets daily function. Combining the two approaches has the potential to overcome the limitations of both approaches, enabling improved cognitive functions and transfer to daily function. Remotely-administrated interventions further make treatment accessible and cost-effective. The current study is aimed at testing the efficacy of a novel, combined, remotely-delivered treatment approach: Cognitive Retraining and Functional Treatment(CRAFT), using a Randomized Controlled Trial (RCT) design. 90 cancer survivors will be randomly assigned to receive 15 weeks of either the combined treatment, computerized training only, or treatment-as-usual. Outcomes will be assessed at completion, and following 3 months of no contact, to test immediate and enduring effects of treatment. Baseline predictors for treatment response will be further assessed. Positive results in the proposed study could potentially change the therapeutic landscape for rehabilitation of cancer-related cognitive decline, which currently impair the lives of millions worldwide.

In this study, the investigators will evaluate the efficacy, safety and related mechanism of dietary fiber and probiotics alone and in combination as a add-on treatment in improving the antipsychotic induced weight gain, the cognitive impairment, and psychotic syndrome in schizophrenia or bipolar disorder patients. The study will recruit 100 schizophrenia or bipolar disorder patients who meet the criteria of DSM-5, and then randomized to 4 groups: probiotics group(PB group) dietary fiber group(FB group) probiotics plus dietary fiber group(PF group) and control group(CT group) for a 12-weeks clinical trail. The specific aims are to compare probiotics group versus controls on: 1) clinical core symptoms; 2) cognition;3)metabolic related markers.

Abstract Objective: Investigators examined the feasibility of applying a participation-focused strategy training intervention to community-dwelling adults with cognitive impairments following stroke and brain injury and evaluated its potential effect on participation. Method: Participants with a diagnosis of stroke or brain injury participated in this single-group, repeated-measures study. Participants received 1~2 sessions of strategy training intervention weekly for 8~18 sessions. Outcome measures included the Participation Measure--3 Domains, 4 Dimensions (PM-3D4D), the Canadian Occupational Performance Measure (COPM), and feasibility indicators (participants' recruitment, retention, attendance, engagement, comprehension, satisfaction, and intervention adherence).

The purpose of this study is to assess whether the combination of choline alphoscerate 1200mg per day and nimodipine 90mg per day given orally is more effective than the combination nimodipine placebo in reducing cognitive decline in patients with subcortical vascular cognitive impairment

The goal of this observational study is to explore the optimal dose of computerized cognitive training in patients with cognitive impairment. The main questions it aims to answer are: Is there an optimal dose of computerized cognitive training for patients with cognitive impairment? Is the optimal dose different in patients in different age populations? Participants enrolled in the study took a reported computerized cognitive training program and the training data were analyzed for exploring the optimal dose. The researchers will compare the different dose groups to see if there is an optimal dose for the highest improvement in cognitive abilities. The researchers will additionally compare two age groups (aged younger than 60y or aged 60y and older) to see if the optimal doses in the two groups are different.
