Filter by:During the worldwide COVID-19 pandemic a large number patients reported different functional complaints one month or later after recovery from the acute infection. This entity had a number of names including "long-COVID" or "post COVID condition". Long-COVID is on the rise and no effective treatment exists yet to improve cognitive function. Recent research has shown that people with even mild COVID had a greater decline in executive function, notably in their ability to perform complex tasks. What drives post-COVID cognitive changes is still a mystery and there are no effective treatments available. One hypothesis is that there is persistent immune activation resulting in reduction in cerebral blood flow. There is evidence that increased CO2 may decrease inflammation, and decreased CO2 may increase inflammation. Objectives: The primary objective of this pilot study is to assess the safety and tolerability of the use of Hi-OX sequential rebreathing for the treatment of post-COVID cognitive dysfunction. The secondary objective is to identify the effects of the use of the Hi-OX rebreathing treatment in changing post-COVID cognitive dysfunction.
Postoperative cognitive dysfunction (POCD) affects all age groups and can lead to increased morbidity and more extended hospital stays. Dexmedetomidine reduces POCD by inhibiting the increase in proinflammatory cytokines IL-6 and TNF-α, and its anti-inflammatory activity contributes to its protective effect. Previous studies found that dexmedetomidine reduced POCD incidence in non-cardiac and cardiac surgery. Therefore, the goal of this study was to specifically investigate if using TCI dexmedetomidine to maintain anaesthesia in laparotomy surgeries reduces the incidence of POCD compared to inhalation anaesthesia by sevoflurane.
The current proposal aims to 1) develop a technical platform and implementation plan for the delivery of a virtual reality-based mindful movement therapy (VR-MMT) protocol for older adults; and 2) conduct a clinical trial to examine the feasibility and preliminary efficacy of an 8-week, 16-session module VR-MMT intervention for this population. The findings of this study will help us to identify engagement barriers and refine the intervention contents as well as the study protocol necessary for the preparation of grant applications to conduct a controlled clinical trial. This study is innovative and high impact as this is the first study to examine the feasibility and preliminary efficacy of a VR-MMT intervention that could potentially ameliorate cognitive and mobility decline and promote psychological wellbeing in older adults by combining a widely accessible technology and creative embodiment-based approach.
This randomized controlled trial evaluated the effectiveness of an immersive virtual reality (IVR) application (focused on a daily activity) to train cognitive functions and its impact on depression and the ability to perform activities of daily living (ADL) in patients with mild cognitive impairment (MCI). With a dose of two sessions per week during six weeks, the study showed significant improvements in cognitive functions and reduction in depression, with notable effects in the experimental group. This underscores the potential of IVR as a valuable tool in the management of MCI.
VESPA 2.0 is based on an integrative and ecological approach used for the treatment of cognitive dysfunction in patients with MCI or other neurodegenerative disorders.
This study evaluates cognitive dysfunction status and related factors in patients with chronic low back pain over the age of 60.
This study is a retrospective, observational study that aims to include patients undergoing cardiac surgery. 1. Evaluate the preventive effect of ursodeoxycholic acid on post-cardiac surgery cognitive dysfunction over the past eight years. 2. Utilize the pre-existing preoperative and postoperative 24-hour plasma samples from previous studies to measure the levels of glycocalyx and its related regulatory factors. 3. Assess the clinical correlation between the measured parameters and patient outcomes.
The goal of this pilot Study and Randomized Controlled Trial is to investigate the impact of electroacupuncture on cognitive function, quality of life (QoL), and depression severity in patients with major depressive disorder (MDD). The main question[s] it aims to answer are: - Primary : electroacupuncture has the potential to treat subjective cognitive complaints and cognitive impairment in MDD outpatients - Secondary : electroacupuncture has the potential to treat depressive in MDD outpatients The 60 participants will randomly be assigned to either the treatment group or the control group in a 1:1 ratio. The treatment group will undergo electroacupuncture (EA), while the control group will receive sham acupuncture within 10 weeks period. Both groups will receive antidepressants with adjunctive medication (i.e., benzodiazepines, tricyclics, or antipsychotics) as the standard treatment. All participants will be assessed for executive functions and memory using specific cognitive tests, including the Trail Making Test B (TMT-B), Stroop Color and Word Test (SCWT), category delayed recall in the Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog), and subjective reports of concern regarding concentration, memory, problem-solving, learning, communication, and quality of life (QoL) concerns using the WHO Disability Assessment Schedule (WHODAS 2.0; sections D1.1-1.6 and H1-3), and depressive symptoms were assessed using the Thai-PHQ-9.
There are two important aspects in which the present project will allow to enrich our understanding of compensatory brain activity in older adults. First, in the studies that have been conducted so far the compensatory brain activity in older adults was investigated primarily with the use of the functional magnetic resonance (fMRI) or positon emission tomography (PET). In order to identify compensatory activity in our study we will use electroencephalographic markers (observable in EEG). It will allow to confirm the assumptions about compensatory brain activity relying on new data, as in EEG research the brain markers of the same cognitive processes are different from those used in fMRI and PET research. What is more, in the studies conducted so far brain activity in older adults was only registered and interpreted, whereas the present study additionally adds the training component. The aim of our study is to see if it is possible to influence the compensatory brain activity through cognitive functions training, relying on working memory training. Theoretically, such a training should optimize brain activity in older adults, namely evoke compensatory brain activity during difficult tasks in order to make them easier, whereas in the case of easy tasks it should lead to the disappearance of the need to trigger compensatory activity. This assumption will be verified in an experimental setting. The participants will be divided into six groups: two experimental (the groups of young and old adults), and by analogy two active control groups and two passive (no-contact) control groups. The experiment was designed in the following way: (1) All groups will be subjected to pre-test measurements that will be EEG registration during a cognitive task execution at different difficulty levels; (2) Experimental groups will undergo working memory training. Over the period of 4 weeks participants in the experimental groups will take part in 12 training sessions. In the active control groups instead of the n-back training the practice of tasks which do not involve working memory will be introduced. Participants of the passive control groups will be awaiting post-test (no-contact control); (3) In all groups post-test measurements will be administered analogically to the pre-test measurements in order to assess changes in cognitive tasks performance and related brain activity.
Background: Ageing is frequently accompanied by physiological changes that might result in a deterioration in physical and cognitive abilities, which frequently leads to institutionalization or the loss of autonomy. Mild cognitive impairment (MCI) is an intermediate state between normal cognitive aging and early dementia, the optimal period to intervene with preventive strategies and early treatments. Thus, the current study intends to investigate the effects of aerobic and computer-based cognitive training on age-related cognitive decline. Methods: This is a single-blinded, randomized controlled trial. Elderly patients with mild cognitive impairment (n = 60) will be randomized to 2 arms and treated for 12 weeks: arm 1 (aerobic exercise and computerized cognitive training) and arm 2 (Placebo; will not receive any intervention). Outcome measure used were Montreal Cognitive Assessment (MOCA) test, Barthel Index (BI) and short form survey-12 (SF-12). Statistical Analysis: To compare the baseline characteristics and outcome variables between the two groups, independent t-tests was employed. A two-way repeated measures ANOVA was utilized to determine the interaction effect of time (baseline, post-treatment, and follow-up) and group (intervention vs. control) on the outcome measures.
