Filter by:The relationship among hypertension, aging and cognitive decline is complex and not completely understood. Purpose of this project will be evaluating early markers of cognitive deterioration in patients with arterial hypertension. In particular, this cross-sectional observational study will be articulated in three phases: 1. Neuropsychological evaluation of general cognitive abilities 2. Identification and measurement of specific biomarker levels 3. Correlation among hypertension, cognitive abilities and biomarkers.
The primary purpose of this study is to determine the efficacy and safety of Sodium Oligo-mannurarate (GV-971) in 36-week treatment of mild to moderate Alzheimer's disease.
The purpose of this study is to assess the performance of AclarusDx™, an investigational blood test detecting gene expression information, and intended to help physicians in making an Alzheimer's Disease diagnosis in patients having memory complaint and/or cognitive impairments.
The purpose of this study is to investigate the effectiveness of a preventative low-dose of Haloperidol to prevent delirium in patients undergoing a esophagectomy, pneumonectomy or thoracotomy. Delirium is state of severe confusion and some symptoms include: - Cannot think clearly - Have trouble paying attention - Have a hard time understanding what is going on around them - May see or hear things that are not there. These things seem very real to them.
Insulin-like growth factor 1 (IGF)-1 is an important neuromyotrophic hormone. Disregulation of this hormone has been reported to influence the genesis of cognitive impairment and dementia in the elderly patients. We analyzed the possible link between IGF-1 and risk of Sarcopenia and Mortality in a cohort of elder patients with cognitive impairment.
Complaints about memory and thinking are common in women as they go through menopause and estrogen levels fall. The ovarian hormone estrogen is important for supporting normal cognitive function, and changes in brain activity and function occur when estrogen levels are decreased. Estrogen is also important for maintaining healthy blood vessels which also support normal cognitive function. In Alzheimer's disease and other types of dementia, there is significant damage to the blood vessels in the brain. This study will test whether changes in brain activity and function with the loss of estrogen are related to changes in vascular function. The investigators will measure vascular function using ultrasound, and brain activity using MRI scans in women who are enrolled in the Females, Aging, Metabolism and Exercise (FAME) study (NCT01712230). In the FAME study, healthy premenopausal women either take a medication to decrease their estrogen levels, or a placebo. This sub-study may provide new information about how estrogen affects vascular function and cognitive function, and lead to new ways to prevent or delay cognitive impairment or dementia.
Spinal cord Injury (SCI) is a condition commonly associated with a state of chronic low-grade inflammation due to a variety of factors such heightened risk for infection and development of metabolic disorders. Many disorders which have been demonstrated to have an inflammatory basis have also been found to be at much higher prevalence following SCI. Such conditions include, but are not limited to, depression, cognitive impairment, neuropathic pain, and somatic/autonomic nerve function. The fact that such disorders have an inflammatory basis provides a unique opportunity to treat them with intervention strategies which target the immune system. Natural anti-inflammatory interventions including a diet consisting of foods and supplements with anti-inflammatory properties may be an effective option for treating inflammation in this population. As this treatment strategy will target the inflammatory basis of many disorders it would be expected to lead to a reduction in pro-inflammatory mediators thereby leading to more sustainable long-term immune improvements regarding enzyme function and protein balances. Despite this, surprisingly little research has focused on the use of anti-inflammatory foods for the treatment of chronic inflammatory conditions, and effects specific to SCI have been almost completely neglected. As such, the current study will focus on the daily intake of natural supplements with anti-inflammatory properties over a 3 month intervention and the effects on inflammation and associated disorders will be assessed. It is hypothesized that the supplementation will result in positive alterations in enzyme regulation and protein balances resulting in improvements in each of the outcome measures of interest.
Data from subjects who had previously been dosed with Flutemetamol (18F) Injection and imaged in Study GE-067-007, and who died on or before 10 June 2013, will be analyzed. The PET brain images previously obtained in Study GE-067-007 will be interpreted visually in randomized by 5 independent readers who are blinded to all other subject information, and the images will be classified as abnormal (positive for abnormal neuritic plaque density) or normal (negative for abnormal neuritic plaque density). The numbers of images in each category will be used to calculate sensitivity and specificity.
The investigators hypothesize that the improvements in insulin sensitivity, beta (β)-cell function, and inflammation will be greater, and the improvement in sarcopenic obesity will be less, in younger versus older individuals after substantial weight loss induced by sleeve gastrectomy bariatric surgery.
The purpose of the study will be to determine the effects of the Cognitive Orientation to daily Occupational Performance (CO-OP) as a treatment program for individuals with Parkinson's disease-related cognitive impairment. The potential effects of the CO-OP on successful engagement in meaningful activities will be examined from participants' and live-in caregivers' perspectives. Effects of the CO-OP on participant-perceived health-related quality of life and caregiver burden will also be evaluated. Hypotheses: 1. Training with the CO-OP will have an effect or multiple effects on participation in meaningful activities and health-related quality of life for individuals with Parkinson's-related cognitive impairment. 2. Training with the CO-OP will have an effect or multiple effects on caregiver burden and health-related quality of life for caregivers of individuals with Parkinson's-related cognitive impairment.
