Active clinical trials for "Cognitive Dysfunction"

Constituents of grapes have been studied for their antioxidant, anti-inflammatory, and anticarcinogenic properties. In the past decade, there has been emerging evidence regarding a potential role for grapes in slowing cognitive decline and other effects of aging. Furthermore, evidence has been obtained in vivo that supplementation with grape seed extract in aged rats improves cognitive performance, and that supplementation with grapes in people having decline in cognition leads to preservation of metabolism in brain regions important to cognitive function over a period of six months. The investigator aims to measure effects of grape intake on cerebral metabolism and neuropsychological performance, and to determine whether initial patterns, and magnitude of change, of cerebral metabolism assessed by positron emission tomography (PET) can serve respectively as a predictor of, and biomarker for, the magnitude of cognitive changes resulting from intake of grapes over a period of at least one year.

This study evaluates the effects of Mindfulness-based Interventions (MBI) on the neuropsychological profile of individuals with mild cognitive impairment (MCI). It will also investigate changes in fMRI activity, such as resting-state functional connectivity networks and changes in activity in attention networks in task-related fMRI using graph theory analysis after Mindfulness-based Interventions. Participants will be randomly assigned to receive either the Mindfulness-Based Intervention, Cognitive Rehabilitation Training or Treatment as Usual as the passive control group comparison.

Qi Zhi Tong Luo (QZTL) capsule, a traditional Chinese herbal medicine, which was used to treat stoke-related symptoms, include trouble speaking, paralysis and trouble walking. This study aimed to evaluate the efficacy and safety of QZTL capsule in the treatment of vascular cognitive impairment. This study was designed as randomized, double-blind, parallel, placebo-controlled, multicentre trial. It consisted of a single-blind run-in period using placebo only (2 weeks) and a double-blind treatment phase after randomization (24 weeks), and follow-up 12 weeks after withdrawal.The primary efficacy variables included changes from baseline in the Clinical Dementia Rating scale-Sum Box (CDR-SB) and the Mini-mental State Examination (MMSE) after 24 weeks of treatment. The secondary efficacy measurements include the Clock Drawing Test (CDT), Hopkins Verbal Learning Test (HVLT) and Ability of Daily Living (ADL).

This is an open label feasibility trial to learn whether the combination of donepezil and cognitive remediation therapy (Donepezil + CRT) may improve neurocognitive functioning and decreasing alcohol use in Veterans with alcohol use disorder who have mild cognitive impairment (AUD-MCI). The study will determine the acceptability and adherence to treatment and preliminary evidence for efficacy. The study will recruit 15 newly recovering Veterans individuals with AUD-MCI for a 13-week, open-label, single-arm pilot study with sobriety and cognitive assessments at baseline and at 13-week follow-up.

A Sub-Study of an investigator initiated and conducted, multicentre, international, double-blinded, placebo-controlled, parallel-group, randomised controlled trial (TRIDENT) to determine the effect of more intensive long-term blood pressure control, provided by a fixed low-dose combination blood pressure lowering pill ("Triple Pill") strategy on top of standard of care, for slowing memory decline as measured by Cambridge Neuropsychological Test Automated Battery (CANTAB), in patients with a history of acute stroke due to intracerebral haemorrhage (ICH).

In the current application, the investigators propose to elaborate upon, reconstruct and advance to pivotal trial readiness a recently validated mobile application (HeartMapp), designed for the ecological momentary assessment and treatment of individuals with Heart Failure (HF). Presently, HeartMapp includes physiological modules (PM) that support self-monitoring and exercises that promote heart health, and cognitive modules (CM) that track and enhance cognitive functions. During the first three-months, the investigators will finalize the cognitive training modules within HeartMapp and release through the quality management system. At the completion of software development, the investigators propose to test the relevant usage and progression variables of the algorithm that will be used to direct engagement with the app. The investigators will conduct a single arm, open label, pilot clinical trial to examine feasibility and initial efficacy of the HeartMapp+CT (HeartMapp and computerized plasticity-based adaptive cognitive training). The term "CT" refers to computerized training. The study will enroll 32 adults aged 40 and older with a diagnosis of HF and over sample by 25% to reduce attrition for a total of 24 participants enrolled at the end. Participants will complete follow-up assessments at 3- and 6-months after enrollment.

This study investigates the effect of vildagliptin, an inhibitor of the enzyme DPP-4, on the cognitive functioning of elderly diabetic patients with mild cognitive impairment (MCI) documented at mini mental state examination (MMSE). In this prospective study, 60 diabetic elderly people were enrolled and divided according to their glycated hemoglobin (HbA1c) values in 2 groups: Group A, (HbA1c <7.5%, n=30) treated with metformin, and Group B (HbA1c >7.5%, n=30) treated with metformin plus vildagliptin. We evaluated MMSE, fasting plasma glucose (FPG) and HbA1c at baseline and after 24 weeks treatment.

A randomized, double-blind, placebo-controlled, two arm cross-over study to determine whether a specific combination of Andrographis paniculata and Withania somnifera can be regarded as a safe and effective treatment for cognitive deficits.

Primary objective is to evaluate the neuroprotective effect of T-817MA on Tau protein phosphorylated at threonine 181 (p-tau 181) in cerebrospinal fluid (CSF) compared with placebo in patients with a diagnosis of MCI due to AD or mild AD. Secondary objectives are: To evaluate in patients on T-817MA and placebo: cognitive function measured by the Clinical Dementia Rating Scale Sum of Boxes (CDR-sb) and working memory and attention domain as measured by the Cognitive Functional Composite (CFC). AD-related biomarkers in CSF and plasma imaging analysis using volumetric magnetic resonance imaging (vMRI) alpha/theta ratio of the electroencephalogram (EEG) To evaluate the safety of T-817MA by clinical laboratory tests and adverse events (AEs). To evaluate the pharmacokinetics of T-817MA
