Filter by:There is lack of information on the risk factors of accelerated cognitive decline in older people with Alzheimer disease (AD). The extent of neurodegeneration and white matter disease has been reported to be important factors. In addition there may be biomarkers e.g. inflammatory cytokines that can contribute to cognitive decline. The impact of care arrangement and physical activity may also be important. Insulin signaling is impaired in Alzheimer disease (AD). We therefore propose to perform a cohort study of older people with AD. This will be based on an on-going AD registry which was designed to identify genetic biomarkers for AD. Detailed neurocognitive tests and lifestyle information are available. In addition, volumetric MRI brain scans were performed in all AD subjects. The hypothesis is that MRI brain volumes, serum biomarkers, physical activity, physical functioning are independently associated with cognitive decline in older people with AD. The objective is to identify risk factors of accelerated cognitive decline so that preventive measures can be designed to delay dependency in AD.
Long-term cognitive dysfunction greatly influences patient's quality of life after critical illness. However,its neurophysiological basis remains unknown.This is a 3 year fMRI study conducted at the Jiangyin people's Hospital. This study utilize resting-state functional magnetic resonance imaging(fMRI) to investigate the regional alterations in survivors with cognitive impairment.Further, the investigators hypothesize that these regional changes in fMRI activity are predictive of cognitive impairment.
Cognitive impairment or dementia is their last degree in one of the main concerns at a social level in these ages. To this day, there are different pharmacological and non-pharmacological therapies that can help prevent deterioration, as in this case, physical exercise. In the existing scientific literature, you can find a lot of information about the effect of aerobic exercise on cognition, but little is known about the effect of force exercise and its effect on general cognition and executive functions. Therefore, in this research the investigators will investigate the effect of strength training in people over 60 with a diagnosis of mild cognitive impairment in executive functions. For this, a controlled and randomized clinical trial will be developed in the city of Seville
This study is a prospective, multicenter, randomized (1:1) controlled comparative effectiveness trial of a transseptal approach to left ventricular ablation compared to a retrograde aortic approach to prevent cerebral emboli and neurocognitive decline in adults with ventricular tachycardia (VT) and/or premature ventricular contractions (PVCs).
Using the therapy of early intervention with Qianyang Yuyin Granules to improve cognitive impairment caused by hypertension.
Alzheimer's disease (AD) is the most common cause of dementia and currently has no disease modifying treatments or simple accurate diagnostic tests. The goal of this project is to study how tau (a protein thought to cause AD) is made, transported and cleared in the human body. Better understanding of these processes may lead to improved understanding of AD, earlier diagnosis and a way to evaluate treatment.
Participants will be randomized to exercise intervention and control groups, for 6 weeks. The participants will be examined for following test Mini mental state examination, Trail making test A and B, MOCA. The intervention will consist of twice weekly, 55- 60 minute exercise session for experimental group The participants of control group will receive 20 minutes treadmill walk thrice weekly. Participants will walk at constant pace with zero inclination such that a subjective rate of perceived of 5 to 7 points on the ten-point Borg scale will be reached. Assessment of both groups will be done on first session and on last session.
This study will measure the oral bioavailability and pharmacokinetics of known bioactive compounds from a standardized Centella asiatica water extract product (CAP) in mildly demented elders on cholinesterase inhibitor therapy. Compound levels will be measured in human plasma and urine over 10 hours after acute oral administration of two doses of the botanical extract product. The dose giving maximum plasma levels (Cmax)closest to those observed in the investigator's mouse studies, the area under the curve (AUC0-12), as well as the rate of clearance (t ½) of the known compounds and time of maximum concentration (tmax), will be identified. These data will be used to inform decisions on the dosage and dosing frequency for future clinical trials.
To test the long term effect of a light treatment on cognition, sleep and metabolism in patients with Mild cognitive impairment (MCI) or mild Alzheimer's disease or related dementia (ADRD).
Cognitive function is the mental action or process of acquiring knowledge and understanding through thought, experience, and the senses. Cognitive impairment describes a noticeable decline in cognitive function which can be temporary or permanent. This decline is measurable and ranges from mild to severe depending on the degree of decline in function. Cognitive impairment can be caused by a variety of diseases or conditions, and it is not limited to a specific age group. It can occur in patients following acquired brain injury such as traumatic brain injury and stroke. Some causes of cognitive impairment are related to health issues that may be treatable, such as medication side effects, vitamin B12 deficiency, and depression. Cognitive impairment has a significant impact on rehabilitation outcome and quality of life. It has significant health and economic impact. People with cognitive impairment report three times longer stay in hospital compared to people hospitalised for other conditions. Cognitive rehabilitation is the process by which cognitive function can be improved and reduces the impact of cognitive impairment. Cognitive rehabilitation helps to improve functional outcomes and quality of life of patients with cognitive impairment. Current cognitive rehabilitation protocols use face to face interaction which cannot optimise the intensity of therapy due a lack of resources. Many areas of UK do not have dedicated cognitive rehabilitation service, programme or personnel and where it exists, the service is restricted largely to the urban centres. These services have high patient to staff ratio with prolonged waiting times often extending over 12 months to access input. Innovative technologies with telemedicine may well bridge the gap in service provision, improve engagement and offer opportunities in resource management. Gamification refers to the application of typical elements of game playing (e.g. point scoring, competition with others, rules of play) to other areas of activity (such as healthcare) to encourage engagement and motivation. It is increasingly being used in rehabilitation and provides a means of developing more effective treatments and interventions. Practice and repetition are key rehabilitation processes that can be enhanced through the use of gamified innovative technology. This protocol describes a trial of an innovative rehabilitation tool for community dwelling adults with cognitive impairment following acquired brain injury. The intervention is a novel interactive system connected to a television set using 3D cameras and tailored software to deliver therapeutic activities to patients within their homes. Each participant will be required to have 2 sessions per week using the device. Each session will last about 20 minutes with 4 different activities of 5 minutes duration each, targeting different domains of cognitive function. Follow up assessments will be carried out after 12 weeks of using the equipment. The primary outcome measure will be the change in the assessment scores on the cognitive tests administered before and after undergoing the rehabilitation programme. Secondary outcomes on quality of life, participation in leisure time activities and satisfaction with the use of the equipment will also be obtained. Safety while using the device will be monitored and any side effects from engaging in the activities will also be monitored.
