Filter by:The purpose of the BEAM study is to compare the effects of a low-carbohydrate diet and a lowfat diet for adults with mild memory loss and adults with pre-diabetes. The data collected will help determine changes in cognitive function, brain structure and function, and levels of certain proteins and hormones in body fluids.
This study is a 52-weeks, multicenter, randomized, double-blind, placebo controlled, parallel trial which will be carried out in 15 centers around China. The study population includes amnestic mild cognitive impairment patients (planned a total of 240) aged 55-85 in both gender. Participants will be randomly allocated to 1612 capsules (1.14g per time, 3 times per day) or placebo for a 52-weeks double-blind treatment period. The primary outcome measure is change from baseline in the Alzheimer's Disease Assessment Scale- Cognition Subscale (ADAS-cog) and rate of conversion to dementia. The secondary outcomes are changes from baseline in the Mini-Mental State Examination (MMSE), Delayed Story Recall test (DSR), Alzheimer's Disease Cooperative Study/Activities of Daily Living scale adapted for MCI patients (ADCS/MCI/ADL24). Safety is being assessed by observing side effects and adverse reaction during the entire treatment period. Statistical analysis will be conducted according to per-protocol population and intend-to-treat population and the safety will be analyzed in safety set.
This study is a 52-weeks, multicenter, randomized, double-blind, double- placebo, parallel controlled phase VI trial being carried out in 20 centers around China. The study population includes amnestic mild cognitive impairment patients (planned a total of 360) aged 55-85 in both gender. Participants will be randomly allocated to Qinggongshoutao bolus (7g per time,2 times per day) and placebo identified to Ginkgo biloba (Ginaton), Ginkgo biloba (Ginaton) (80mg per time, 2 times per day) and placebo identified to Qinggongshoutao bolus, or placebo identified to Qinggongshoutao bolus and placebo identified to Ginkgo biloba (Ginaton) for a 52-weeks double-blind treatment period.

Losing the ability to walk can lead to fewer opportunities to socialize with friends and family and participate in the community. When this happens, powered wheelchairs can provide access to homes and communities, contributing to health and well-being. Training by a qualified occupational therapist allows an individual to use a powered wheelchair safely and effectively. Learning to drive a powered wheelchair can be difficult, frustrating and time consuming for people with cognitive and physical challenges. In this study, the investigators will ask participants with cognitive impairments to complete training with an occupational therapist using either a shared control wheelchair or training methods according to the standard of care. The investigators believe shared control training, entitled Collaborative Powered mobility Innovative Learning OpporTunity (CoPILOT) will enhance driving skill while maximizing safety learning. CoPILOT has the potential to enable people to participate more in their day to day lives and regain mobility independence.
Primary objectives: Assessment of the incidence of postoperative cognitive dysfunction (POCD), cerebrovascular accident (CVA), and delirium after minimal invasive coronary artery bypass grafting (Endo-CABG). Secondary objectives: - Quality of life, three months after endo-CABG - Patient satisfaction with endo-CABG and the tests performed - The influence of various demographic and peri-operative variables on neurological outcome after endo-CABG - Incidence of fear and depression, 3 months after endo-CABG
Over the past ten years, the number of endovascular procedures has increased by 5% per year in Europe with the development of interventional cardiology, such as percutaneous coronary angioplasty, aortic valve replacements (TAVR), and vascular endoprosthesis. The neurological lesions detected on cerebral MRI caused by these endovascular procedures are frequent with an incidence of about 30-70%. These events, although subclinical, have an impact on morbidity and mortality and especially on long-term cognitive decline. TAVR is the reference treatment for symptomatic elderly patients with stenosis of the aortic valve, considered by a multidisciplinary "Heart Team" as at high surgical risk due to comorbidities, age and high perioperative risk scores ( Euroscore 2 and STS scores). Despite the net clinical benefit, an increase of silent neurological events was detected on post-procedural cerebral MRI with an incidence of approximately 70%. The epigenetic involvement in the occurrence of ischemic cerebral lesions is still largely unknown. Epigenetic mechanisms, such as DNA methylation, can be associated with aging processes and modulate the risk of developing cerebrovascular pathologies. They are likely to provide new biomarkers that predict the risk of brain damage. Hypomethylation of leukocyte DNA is directly related to atherosclerosis in humans. This hypomethylation of DNA would represent an easily measurable marker reflecting the presence and progression of atherosclerosis. Because atherosclerotic lesions often precede the clinical manifestation of ischemic cardiovascular disease, such as ischemic heart disease and stroke, DNA hypomethylation could be used to identify individuals at risk for cerebrovascular events. The investigator hypothesize that hypomethylation of leukocyte DNA can predict the risk of developing new ischemic brain lesions especially after a TAVI procedure.
The investigators are conducting a pilot study to compare cognitive outcomes among Veterans with severe aortic valve stenosis who are scheduled to undergo either aortic valve replacement.
Cancer-related cognitive Impairment (CRCI), commonly referred to as "chemo brain" or "brain fog"-impact severely on the Quality of Life (QoL) of cancer survivors. However, it still remains underdiagnosed and challenging to treat. One of the treatment options is the use of psychostimulants such as Methylphenidate (MP), but well-designed clinical trials to test its efficacy are limited. We will conduct a phase II study with a mixed method design to explore the preliminary efficacy of MP to improve cognitive function and QoL in breast cancer patients after treatment with chemotherapy and/or radiotherapy and determine the parameters needed for designing a phase III study.
The Neurotrack Virtual Cognitive Health Study is a 12-month long, prospective study that aims to evaluate the impact of the Neurotrack Virtual Cognitive Health Coaching Program on cognitive ability, anxiety and depression, and lifestyle behaviors for individuals who show signs of subjective cognitive decline.
The purpose of this study is to examine the feasibility and acceptability of a 12-week care management program for medically complex Veterans with cognitive impairment, delivered via telephone or videoconferencing.
