Active clinical trials for "Cognitive Dysfunction"

Widespread recognition of the current and projected impact of the dementia epidemic has spurred research into novel drug discovery efforts. It is well recognized by most that Alzheimer's disease is not the only form of dementia and that beginning to turn attention to other disease states is critically important in order to alleviate this burden on the elderly population today This proposal seeks to further progress in this area through the repurposing an existing drug therapy as a potential treatment for Hippocampal Sclerosis of Aging. This disease is seldom recognized clinically and yet is the number one Alzheimer's disease mimic the confounds are diagnostic and treatment of subjects suffering from dementia and as of yet has no potential therapeutic interventions identified. As such, the proposed study represents a cutting-edge, data-driven, low-cost, exploration of a novel disease relevant pathway that may hold promise for global efforts targeting late life dementia which is a major health priority in America today.

Elderly patients with hip fracture are older and have a high incidence of perioperative complications. the postoperative recovery of elderly patients with hip fracture is affected by hemodynamic instability and pain caused by fracture. S-ketamine is the S-isomer of ketamine. Compared with traditional ketamine, S-ketamine has stronger analgesic effect and fewer adverse reactions of nervous system. The parasympathetic effect of S-ketamine can antagonize the circulatory inhibition of propofol and make the hemodynamics more stable in elderly patients with hip fracture.Iliac fascial space block (fasciailiacacompartmentblock,FICB) mainly depends on local anesthetics spreading to the femoral nerve, lateral femoral cutaneous nerve and obturator nerve in the iliofascial space to achieve analgesia in its dominant area. Ultrasound-guided iliac fascial space block can effectively reduce the amount of anesthetics and has shorter puncture time and fewer complications. It can more effectively reduce the perioperative pain of elderly patients with hip fracture.

To investigate the effect of trazodone on sleep, hippocampal-dependent memory and hippocampal excitability. The investigators hypothesize that trazodone will improve total sleep time and proportion of time in Slow Wave Sleep (SWS).

The investigators propose to apply neuroplasticity-based computerized cognitive remediation (nCCR) to improve memory function in patients with Mild Cognitive Impairment (MCI).

Background: Cognitive impairment appears frequently in cancer survivors, negatively affecting the quality of life and emotional well-being of patients. This study compares the effectiveness of a well-established treatment (cognitive rehabilitation) with the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP) to alleviate these cognitive deficits and evaluate its effect on anxiety-depressive symptoms and the quality of life of survivors. Methods: A three-arm randomized superiority clinical trial, with a pre-post and follow-up repeated measures and intergroup design with a 1:1:1 allocation ratio will be carried out. A hundred and twenty-three breast cancer survivors with mild to moderate cognitive impairment will be randomly assigned to one of the interventions of the study: cognitive rehabilitation intervention group, an intervention group with UP intervention, or a control group on the waiting list. The primary outcome is to observe a significant improvement in cognitive function and quality of life in both intervention groups and a significant decrease in emotional impairments in comparison with the waitlist group. These results will be maintained at six months of follow-up. Discussion: The aim of this work is to test the efficacy of the Unified Barlow Protocol in reducing cognitive deficits in breast cancer survivors. The results of this trial may be useful in reducing the presence of cognitive problems in survivors and improving their emotional state and quality of life.

The aging of the population has led to an increase in the prevalence of disabling and high-cost diseases, such as dementia and Mild Cognitive Impairment (MCI). The latter can be considered a prodromal phase of some dementias and a critical stage for interventions to postpone the impairment of functionality and thus maintain a better quality of life. A cognitive function to intervene in working memory (WM) since it represents the fundamental component of executive functions and is the gateway to maintaining long-term memory. This project proposes an intervention to enhance WM in these users, combining cognitive training with non-invasive brain stimulation, specifically transcranial electrical stimulation of alternating current (tACS). This proposal arises from recent evidence showing that it is possible to increase the capacity of WM in users with MCI through cognitive training. Along with this, tACS has been proposed as a specific neuronal plasticity inducer for the oscillatory pattern required for each mental process. WM is a process particularly susceptible to being enhanced by this technique, as the underlying electrophysiological oscillatory patterns of this process are well described. Thus, tACS would act as a potentiator of the residual capacity of WM in patients with neurodegenerative diseases. This study is a phase II randomized, double-blind clinical trial with a 3-month follow-up. The study will be of 62 participants diagnosed with MCI over 60 years from Valparaíso, Chile. Participants will receive intervention that will combine 12 cognitive training sessions with non-invasive brain stimulation, specifically tACS. Depending on the intervention group to which they will be assigned, in 8 of these sessions, participants will receive either tACS or sham stimulation. Sessions will last approximately 1 hour and take place twice a week, over six weeks. The primary outcomes will be the electroencephalographic measurements, and the secondary effects will be cognitive assessments of WM. The outcomes will be performed before, immediately after, and three months after the end of the intervention. The outcomes of this trial will add evidence about the benefits and feasibility of an intervention that combines cognitive training with non-invasive brain stimulation. The objective is to contribute tools for optimal cognitive treatment in patients with MCI. To enhance WM capacity, postpone the impairment of functionality, and obtain a better quality of life.

The study will be a 36-week multicentre, double-blind, placebo-controlled phase Ⅱb trial in China. Total 360 participants aged 55-80 years will be randomized to Tian Ma Bian Chun Zhi Gan group (84mg per day) or to placebo group. The primary endpoint will be Vascular Dementia Assessment Scale-cognitive subscale and Clinical Dementia Rating-Sum of Boxes. Secondary outcomes included changes in Mini-Mental State Examination, Clock Drawing Test, Delayed Story Recall and Ability of Daily Living. Patients' safety will be assessed by recording of adverse events, clinical examinations, electrocardiography and laboratory tests. The patients, caregivers, and investigators will be blinded to the treatment allocations.

Financial Abilities (FA) are a set of capacities that allow a person to independently manage her/his financial affairs in a manner consistent with personal self-interests and values. This project will: a) assess Financial Abilities in different neurological conditions: Mild Cognitive Impairment, Parkinson's disease and Stroke patients; b) investigate both cognitive correlations, specifically the role of executive functions, thought to be critically involved in the FA multi-dimensional concept, and neuro-anatomical correlates of Financial Abilities; c) build a rehabilitation tool in order to improve FA. Secondary aims are to apply this rehabilitation tool at long distance and evaluate its behavioral, functional and neuroanatomical effects. The starting point for this project is the recently published NADL-F - Numerical Activities of Daily Living - Financial, a multi-domain ecological battery aimed at assessing FA in healthy people as well as in neurological patient populations

This randomized controlled trial will evaluate the impact of an Internet-delivered cognitive behavioral therapy for insomnia (CBT-I) intervention on sleep and the extent to which it contributes to cognitive health in individuals with mild cognitive impairment. Participants with insomnia who meet the study criteria for mild cognitive impairment will be recruited to determine the effects of the CBT-I intervention compared to a patient education condition on sleep and cognition. Internet-based recruitment methods will be used, and outcomes include sleep variables, daytime variables, and cognitive status.

The primary purpose of this study is to evaluate the effect of SAGE-718 on cognitive performance in participants with Alzheimer's Disease.
