Active clinical trials for "Cognitive Dysfunction"

A monocentric prospective open study to evaluate the frequency and nature of cognitive complications in the 3rd month post pulmonary transplant.

Cognitive outcome (delirium and post-operative cognitive deficiency) in patients undergoing two-time liver resection.

This study may determine the incidence of complications that occur after patients undergo a surgery called Carotid Endarterectomy (CEA), which is a surgery that aims to decrease the risk of strokes in patients with a condition called carotid stenosis. Medical records will be accessed to find any information pertaining to postoperative complications. Additionally, it may determine the cognitive dysfunction of patients undergoing CEA, assessed by Mini Mental Status Examination (MMSE).

Older people are a rapidly growing proportion of the world's population and their number is expected to increase twofold by 2050. When these people become patients that require surgery, they are at particular high risk for postoperative delirium (POD), which is associated with longer hospital stays, higher costs, risk for delayed complications and cognitive dysfunction (POCD). Having suffered an episode of delirium is furthermore a predictor of long-term care dependency. Despite these risks, an increasing number of elderly undergo major elective surgery. This is reflected by the frequency of elective spinal surgery, in general, and instrumented fusions, in particular, which has markedly increased over the past few decades. It is yet insufficiently understood, which, particularly modifiable, factors contribute to the development of POD and POCD following these major but plannable surgeries. A better understanding of risk factors would facilitate informed patient decisions and surgical strategies could be tailored to individual risk profiles.

The current study will examine the effects of a brief mindfulness based intervention (BMBI) on mood, memory and attention in comparison to a wait-list control (WLC) group. Participants for the study will be 90 adults aged 50 years and above who have presented at a memory clinic within SLaM NHS Trust with subjective cognitive concerns and/or those who have received a diagnosis of mild cognitive impairment (MCI) from their memory clinic.

The prevalence of neurodegenerative diseases is expected to increase over the next years, in parallel with the aging of the world population. Therefore, it is important to identify new methods to prevent, delay or stop the neurodegenerative waterfall responsible for dementia conversion. To date, there is no fully proven pharmacological treatment for cognitive impairment and the available pharmacological armamentariums have limited efficacy because consist in symptomatic drugs with adverse side effects. On this point, non-pharmacological intervention may represent adjunctive therapy to medications in order to prevent or delay the onset of the cognitive deficits or dementia. This study aims to evaluate the effectiveness of a combined treatment protocol associating a Computerized cognitive training (CoRe) with non-invasive brain stimulation techniques: the transcranial Direct Current Stimulation (tDCS) or the repetitive Transcranial Magnetic Stimulation (rTMS). Patients with mild dementia or Mild Cognitive Impairment (MCI) are enrolled and randomly assigned to the experimental group (CoRe + anodic tDCS/rTMS) or control group (CoRe + sham tDCS/ sham rTMS). All patients are evaluated before (T0) and after (T1) treatment with an exhaustive neuropsychological assessment. Furthermore, follow-up visits are scheduled 6 months (T2) and 12 months (T3) after the end of the treatment.

As complementary and alternative medicines in both Chinese and Western populations, Wu Qin Xi (the Five Animal Play) and Ba Duan Jin (the Eight Pieces of Brocade) have demonstrated small to medium effects on the improvement of various physical, cognitive, and quality of life measures. The purpose of this proposed study is to develop a culturally tailored, low-cost exercise program, "Function Improvement Exercises for Older Sedentary Community-Dwelling Latino Residents (FE-SaLiR)", to improve physical and cognitive functions and quality of life in older Latino adults in a non-clinical community setting. This will be the first study to combine Wu Qin Xi and Ba Duan Jin in non-Chinese population. The study has three specific aims: Following the community-based participatory research model (CBPR), the research team, community health advocates and senior program participants will co-adapt Wu Qin Xi and Ba Duan Jin and co-design the content and delivery form of FE-SaLiR (Phase 1). To conduct a three-arm pragmatic controlled trial to test the feasibility and acceptability of FE-SaLiR in older sedentary community-dwelling Latino residents (Phase 2). To generate the estimates of effect size and retention from the pilot study data that will be used to conduct the power estimation of a large RCT that will compare the effectiveness of FE-SaLiR with other types of exercises in an NIH RO1 grant application. FE-SaLiR Phase 1 was delivered from August 2019 to November 2019. FE-SaLiR Phase 2 started recruiting participants by invitation in January 2020; the exercise program started in February 2020.

Chronic rhinosinusitis presents with a plethora of symptoms including non-rhinologic symptoms such as depression, sleep disturbances & the more recently recognized cognitive dysfunction. It has recently been identified that sinus specific treatments such as endoscopic sinus surgery can improve cognitive outcomes in patients with cognitive deficit secondary to chronic inflammation in the upper and lower airway. However, it remains to be seen whether or not offering surgery to these patients at an earlier date has an impact on the degree of improvement on cognitive function in comparison to patients who have to wait long periods for their treatment.

Study Title: Gene Expression, Meditative Movement and Emotional Distress (GME) Background and Objectives: Breast cancer survivors (BCS) often report decrements in cognitive functioning. Cognitive impairment (CI) is generally understood as resulting from chemotherapy or radiation, but may also result from chronic emotional distress experienced by breast cancer patients and survivors. Meditation and exercise are both known to reduce stress, with growing evidence for the potential of each to also improve cognitive functioning in cancer patients and survivors. A Meditative Movement (MM) program (Qigong/Tai Chi Easy) offers the potential of combining both benefits of meditation and exercise for breast cancer survivors. This is a pilot study, testing the MM program to effect changes in cognitive functioning and associated symptoms/conditions such as anxiety, depression, sleep quality and using gene expression factors as biomarkers to potentially measure the molecular signature of these changes. Forty BCS will be consented and assigned to an intensive eight week MM program. Cognitive functioning and associated symptoms/conditions will be assessed before and after the 8-week MM program to examine the participants' behaviors and symptoms. Peripheral blood samples will be collected before and after the 8-week MM program and will be analyzed for gene expression changes. If successful, this study may provide preliminary data for a full powered randomized control trial if results show promise in the psycho-behavioral outcomes and genomic expression results.

The composite effect of reduced balance, cognition, gait abnormalities/gait disturbances, and physical activity in older adults with mild cognitive impairments (MCI) leads to fear of falling and reduced participation in daily activities, which results in reduced cardiovascular fitness and deconditioning. Although many conventional balance and strength training programs have been implemented for older adults with MCI; these adults do not receive adequate practice dosage to make significant improvements, most likely due to lack of adherence to therapy and/or inadequate incorporation of all domains of the ICF model (body functions and structures, activities and participation) and lack of targeting cognitive-motor interference (deterioration of motor and/or cognitive function when both tasks are performed together). The use of alternative therapies such as dance and virtual reality (VR) has been found to be relatively enjoyable for older adults due to increased motivation, which led to the added improvement of physical and cognitive functioning. The overall aims of this pilot is to test the feasibility of VR-based dance therapy paradigm for older adults with MCI as well as its effect on enhancing balance, gait, and cognition, and physical fitness. Investigators also hope that the net effect of improvement in these domains of health outcomes will result in pre and post reduction of fall risk and improved quality of life of older adults with MCI. The study investigates the effectiveness of a VR (Kinect)-based dance therapy in older adults with MCI by demonstrating its feasibility and compliance rate and also determine the efficacy of the VR-based dance therapy in improving health outcomes such as motor and cognitive functions, thereby reducing cognitive-motor interference. The study will also aim to determine the effectiveness of the VR-based dance paradigm in improving cardiovascular fitness and physical activity (PA) in older adults with MCI
