Filter by:Patients who have suffered from stroke may develop problems with thinking. Moreover, such patients have a high risk of becoming demented, more dependent or dying. Therefore, further studies are urgently needed to find effective and safe treatments. Neuroaid is a Traditional Chinese Medicine which has been shown to stimulate growth of brain cells and connections in animals. Neuroaid may improve blood flow in the brain and functional recovery after stroke in patients. Neuroaid-II is a simplified formula with only the main 9 herbal ingredients of the original formula and no animal ingredients. The NEURoaid II (MLC 901) assessment in cognitively Impaired not demented subjects: a pilot double blind, placebo-controlled randomized Trial on Efficacy and Safety (NEURITES) Study is a 24-week, early phase trial of Neuroaid-II in patients who have thinking problems after stroke. The study aims to investigate the effectiveness of the study drug in improving cognitive performance. The safety of the study drug will be closely monitored using adverse events, laboratory tests and vital signs. The trial is important as it aims to set new standards for the scientific evaluation of Asian Traditional Medicine for integration into standard medicine practice. It may potentially establish a novel therapeutic approach for improving cognition after stroke.
Cognitive impairment associated with chemotherapy is an important reported post-treatment side-effect among breast and other cancer survivors. As some patients report cognitive complaints before the administration of their therapy, some authors suggest an association with psychological risk factors such as distress. Distress, a multifactorial unpleasant emotional experience of a psychological (cognitive, behavioral and emotional), social and/or spiritual nature that may interfere with the ability to cope with cancer effectively, its physical symptoms and its treatment, can easily be assessed by the Distress Thermometer. In this trial we aim to determine if the Distress Thermometer, accompanied by the 38-item Problem List, could predict cancer-related cognitive impairment in patients with hematologic malignancies, and in patients with gynecological, urological, breast, lung or gastro-intestinal cancer receiving curative radiotherapy, chemotherapy, radiochemotherapy, anti-hormonal or targeted therapy.
Odor identification deficits, which are a result of early Alzheimer's Disease (AD) pathology in the olfactory bulb and tract as well as olfactory projection areas in the medial temporal lobe (entorhinal and piriform cortex and hippocampus), lateral and central orbitofrontal cortex and several other regions, occur in AD and strongly predict mild cognitive impairment (MCI) conversion to AD. Our pilot data, along with converging findings in the literature, suggests that odor identification deficits, both incremental change over time and change in response to an anticholinergic challenge, may be clinically simple, relatively inexpensive, predictors of cognitive improvement with acetylcholinesterase inhibitor (ACheI) treatment with potential clinical implications for predicting improvement and monitoring ACheI therapy.
The objectives of this pilot study are: 1. to determine whether a short cognitive test battery administered in the preadmission test center can be used to cognitively stratify elderly patients presenting for elective surgical procedures. 2. to evaluate the cost of cognitive screening in the preoperative testing center in terms of time and finances. 3. to evaluate patient perceptions about the use of preoperative cognitive screening and their outcome expectations from their surgical procedure. Subsequent investigations may evaluate whether preoperative cognitive screening is a predictor of postoperative morbidity and mortality in elderly surgical patients and whether a short cognitive screen administered in the preadmission testing center could be used to identify individuals with baseline cognitive impairments that should be refered for more formal cognitive evaluation.
Mild cognitive impairment (MCI) is believed to be the early stage of dementia. The investigators assume that some psychological and imaging risks may predict the conversion. In the current longitudinal study, psychological and imaging data of people with MCI will be obtained at baseline, and will be followed at 26 weeks and 52 weeks. The predictors will be found in comparison with controls.
Cognitive impairment, commonly reported as difficulty with memory and executive function, is a widely recognized clinical challenge for older persons with heart failure (HF). Little is known about the relationship between brain MRI and cognitive impairment in older persons with HF. A limited number of studies have investigated brain MRI in adults with HF and produced conflicting results. Previous findings are limited by use of lower resolution scanners (1.5 Tesla), lack of MRI techniques (i.e. combining structural sequences with perfusion sequences) and recruitment of mixed age samples. Based on these limitations, the purpose of this research plan is to explore the relationship between brain MRI and cognitive impairment in older persons with HF using high resolution structural and perfusion scans. To accomplish this goal, investigators will compare 40 adults with HF who are age > 65 years old with 40 healthy, gender, age, and education matched controls. Investigators will obtain neuropsychological measures of multiple domains, as well as MRI measurements of the temporal lobe and prefrontal cortex at baseline and 12-months.
This study aims to compare the incidence of new-onset cognitive impairments and change in existing impairment status between AF patients undergoing either catheter ablation or remaining on anti-arrhythmic drugs (AAD) as assessed by Montreal Cognitive Assessment (MoCA).
The AGE (Active Geriatric Evaluation) aims to develop a brief assessment tool adapted to the primary care setting.
The purpose of this study is to study the impact of blood pressure on cognitive performance.
Physical exercise has proven to improve memory including in the elderly. Drugs developed to stop the underlying disease processes that cause Alzheimer's disease may succeed only with multimodal efforts to stimulate brain function. One purpose of the study is to test the clinical benefits of curcumin, a safe and effective compound isolated from the turmeric root (a component of Indian curry spices), which has been found to inhibit several potential disease pathways in Alzheimer's disease. Another purpose of this study is to determine how the addition of a physical exercise program in individuals with early memory problems may affect memory function or brain imaging and blood-based markers associated with Alzheimer's disease.
