Active clinical trials for "Cognitive Dysfunction"

This study is a randomized controlled trial (RCT) of a remotely-delivered, technology-assisted psychotherapy program, supported by an innovative software platform for people with cognitive impairment experiencing anxiety.

Although there are an increasing number of mental health treatment adaptations for older adults, there are still a number of factors to consider when making these adaptations. Cognitive decline is one such factor that places significant burden on older adults and can interfere with traditional mental health therapies. Engage is a behavioral treatment approach that has shown to be effective in treating late life depression. The investigators are testing the feasibility of Engage as a treatment method for late life depression in older adults with cognitive decline. The objective is to corroborate Engage as an alternative late life depression treatment method for a sub-population of older adults with cognitive decline. Cognitive decline poses a unique mental health treatment barrier that is often over looked in younger populations. With a relatively higher prevalence of cognitive decline in older adulthood, it is imperative that a feasible mental health treatment program that can be effective in the presence of cognitive decline.

The research objective of this study is to examine the efficacy of HD-tDCS to the preSMA/DACC region and its influence on verbal episodic memory in patients with MCI or dementia after 10 sessions of HD-tDCS. There will be three treatment arms: two active HD-tDCS (1 mA or 2 mA) and a sham group. A verbal episodic memory task will be completed at baseline, immediately following the last HD-tDCS session, and a 2-month follow-up.

The current study is a double-blind, placebo-control randomized clinical trial examining the efficacy of memory retraining in individuals with Mild Cognitive Impairment (MCI). Impairment in higher level cognitive processing, such as new learning and memory, is one of the most common deficits in individuals with MCI and such deficits have been shown to exert significant negative impact on multiple aspects of everyday life, including occupational and social functioning. Despite these findings, few studies have attempted to treat these cognitive deficits in order to improve the everyday functioning of individuals with MCI. Through a small randomized clinical trial, the investigators found that individuals with MCI with documented cognitive impairment show a significant improvement in their memory performance following a treatment protocol designed to facilitate learning. The current proposal will replicate this finding and further evaluate (a) the impact of the treatment on everyday functioning, (b) the long term efficacy of the treatment and (c) the utility of booster sessions in facilitating long-term treatment effects. We will randomly assign older individuals who meet criteria for a diagnosis of amnestic MCI to a memory retraining group or a placebo control group. Both groups will undergo baseline, immediate and long-term follow-up assessment consisting of: (1) a traditional neuropsychological battery, (2) an assessment of global functioning examining the impact of the treatment on daily activities, and (3) functional neuroimaging. This design will allow the investigators to evaluate the efficacy of this particular memory retraining technique in an aMCI population through the assessment of cognitive function via a standard evaluation. In addition, the investigators will be able to draw conclusions regarding the impact of this particular memory remediation program on everyday life from questionnaires completed by the participant and a significant other. Optional enrollment in pre- post neuroimaging will also allow the investigators to look at changes in the brain.

The objective of the study is to evaluate the effectiveness of cognitive training in people with atrial fibrillation and cognitive decline over 12-week cognitive training. Moreover, the investigators will explore whether the training effect can be maintained.

This study will evaluate the efficacy of working memory training in older adults with amnestic mild cognitive impairment (MCI).

The purpose of this research study is to investigate the relationship between light, the thickness of the pigment at the back of your eye, melatonin levels, and memory. The study will investigate whether changing light distribution pattern from "on-axis"' (i.e., directed along the eye's visual axis to the fovea) to "off-axis" (i.e., directed on the periphery of the eye's visual axis) impact melatonin suppression in 24 mild cognitive impairment participants and 24 healthy, age-matched controls.

Today the therapy options for dementia due to Alzheimer's disease (AD) are limited. One recommended intervention is cognitive stimulation. We try to develop serious games as a further treatment option, also usable in pre-dementia as well as early stages of dementia and for a long period of time. The main objective of this study is to test, if the computerized-cognitive training (CCT) is able to improve the performance in a score quantifying an "AD-specific" component score. Additionally, the neurobiological effects of the training are investigated.

The investigators hypothesize that multi-session anodal tDCS (atDCS) of the left dorsolateral prefrontal cortex (LDLPFC) will induce long-lasting effects in improving cognitive function and reducing cognitive fatigue and fatigability in PD patients with MCI.

Purpose: This randomized, double-blind, placebo-controlled clinical trial aims to evaluate the therapeutic effects of thalidomide in radiotherapy-related cognitive impairment. Further study details as provided by Sun Yat-sen Memorial Hospital, Sun Yat-sen University / Yameitang. Primary outcome measure: cognitive improvement, which is determined by the difference value of ADAS-cog score before and after the treatment of memantine.
