View clinical trials related to Cognitive Dysfunction.
Filter by:Post-stroke cognitive impairment is common in stroke survivors. Cognitive function is related to walking ability. The dual task walking is required for daily activities, however, such ability is even more challenging than single walking for people with stroke. The purpose of present study is to investigate the effects of combining cognitive and treadmill training on cognitive function and dual task walking performance in chronic stroke patients with cognitive impairment.
Examine the impact of the BAILAMOS (TM) dance program on lifestyle physical activity
The objective of this trial is to demonstrate early proof-of-concept for My Healthy Brain, an 8-week group program that directly targets multiple lifestyle factors associated with brain health and prevention of cognitive decline. The investigators will explore the feasibility, acceptability, and effect sizes of improvement in primary lifestyle outcomes as well as secondary outcomes of self-determination and subjective well-being.
Aortic valve stenosis is one of the most common types of heart disease in the aging Western population. While surgical cardiac valve replacement (SAVR) is a standard therapy for patients with aortic stenosis, catheter-assisted aortic valve implantation (TAVI) has developed as an alternative to open-heart surgery, especially for high-risk patients. Recently, increased surgeon experience and improved transcatheter valve systems have led to a global trend to use TAVI in patients with low or intermediate risk. Although cognitive impairment after cardiac surgery is well known, the effect of TAVI on cognitive function has not yet been adequately investigated. The aim of this study is to compare the occurrence and progression of delirium, postoperative cognitive decline (POCD), cerebral infarction, and health-related quality of life (QOL) in patients with intermediate risk for catheter-assisted (TAVI) and surgical (SAVR) aortic valve replacement.
This study investigated the effect of acute multiple joint, structural barbell resistance exercise on information processing speed and conflict-related neural activity in older adults via a crossover, sham control, randomized control trial.
This study compared two active cognitive interventions to evaluate whether one improved memory more than the other in patients with mild cognitive impairment. Participants were randomized to either memory strategy training or spaced retrieval training and completed memory tests before and after 3 training sessions. Participants returned 1 month after treatment to see how well they remembered the learned information. Brain scans (functional MRI) were collected before and after the interventions to see if training changed the way brain regions were functioning.
Postoperative Neurocognitive Disorders are the most common neurological complications after major surgery, which are associated with higher increased mortality and morbidity in elderly patients undergoing major surgery. Until now highly effective intervention has not been established yet. Recent preclinical studies suggest mithochiondrial dysfunction may be linked to pathogensis of (postoperative delirium) POD and postoperative cognitive dysfunction (POCD). As Methylene blue(MB) is a mitochondrial protective agent and a safe drug with long history of clinical use, we propose that mitochondrial-targeted interventions may be useful to prevent POD/POCD in surgical patients.
This study will evaluate the tolerability, feasibility, and efficacy of the AKST1210 column in subjects with end-stage renal disease with cognitive impairment (ESRD-CI) undergoing hemodialysis 3 times per week.
Major cardiovascular surgery is associated with postoperative cognitive decline (POCD), with a deterioration in memory, attention and speed of information processing. A multifactorial pathophysiology is presumed but this study focuses on the role of (neuro)inflammation in the development of POCD after coronary artery bypass grafting (CABG) surgery.
The increasing prevalence of mild cognitive impairment (MCI) in our rapidly aging population prompts the need for devising effective interventions to prevent the onset of cognitive impairment and delay its progression to dementia. The benefits of aerobic exercise on the cognitive function in older adults with MCI are well-documented. However, exercise protocols and outcome measurement tools in the current literature are highly heterogeneous. It is therefore imperative to develop standard exercise prescription protocol for the MCI population or to examine the effectiveness of the existing, well-established exercise guidelines. The World Health Organization (WHO) recommends adults (18 - 64 years of age) and older adults (65 years and older) to perform 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity aerobic physical activity per week to improve cardiorespiratory and muscular fitness, bone health, and reduce the risk of non-communicable diseases and depression. Nonetheless, few studies have determined the effectiveness of the WHO Global Recommendations on Physical Activity for Health guideline in improving cognitive function in older adults with MCI. This study thus aims to evaluate the effectiveness of the WHO Physical Activity Recommendations in improving cognitive function in older adults with MCI. In 2017, the American Academy of Neurology (AAN) updated the Practice Guideline for Mild Cognitive Impairment, in which they recommended patients diagnosed with MCI to perform exercise at least twice a week for at least 6 months to gain cognitive benefits. This recommendation was based on two class-II studies, in which a 6-month twice-a-week 90-minute multicomponent exercise program helped maintain global cognition, and selective attention improved significantly following a 6-month twice-a-week 60-minute multicomponent exercise program. While they provided pivotal insights into clinical practice, there were several limitations for these two studies. For instance, in the study conducted by Nagamatsu et al., only female subjects were recruited, and therefore lead to low generalizability. These two studies focused on multi-component exercise intervention which included resistance training, aerobic training, and balance training, and the duration of each component was short (around 20 - 30 minutes). Studies that focus on single exercise modality with longer session duration are warranted to unveil the efficacy of a certain exercise modality in improving cognitive function. In this study, we will evaluate the effectiveness of aerobic exercise on improving cognitive function in older adults with MCI. We intend to follow the WHO Recommendations, focusing on evaluating the effect of different exercise intensities (moderate versus vigorous) and frequencies (once versus thrice per week) of aerobic exercise on improving the cognitive function in older adults with mild cognitive impairment. In particular, the AAN also suggested that physical activity of at least twice a week is necessary to produce cognitive benefits. We, therefore, aim to investigate whether one session per week would also suffice to improve the cognitive function in older adults with MCI. Aims: To examine the effectiveness of 12-week WHO Global Recommendations on Physical Activity for Health in practice in improving the cognitive function in older adults with MCI.
