Cognitive Intervention for Persons With Amnestic Mild Cognitive Impairment
Mild Cognitive ImpairmentPeople with mild cognitive impairment (MCI) are at a greater risk of developing dementia. Therefore, it is important to develop effective non-pharmacological interventions to facilitate their cognitive and activities of daily living (ADL) function, which will also prevent or delay their progression to dementia and reduce associated healthcare and social costs. There are currently a variety of cognitive interventions, mainly categorized as remediation and rehabilitation approach. Research to compare their contents and effectiveness is strongly needed. The information can be used to individualize cognitive intervention based on specific cognitive profile of the patient. This study aims to determine the immediate and long-term efficacy of the remediation approach and rehabilitation approach in enhancing the cognitive and ADL function. The research questions include 1) whether the rehabilitation approach compared with the remediation approach has better effects on improving ADL function; (2) whether the remediation approach may only enhance the performance on the cognitive tests rather than on the ADL function. This study will also explore whether the attitudes of caregivers on providing ADL assistance affect effects of cognitive intervention.

Low-Dose Ibuprofen in Improving Cognitive Impairment in Patients With Cancer
Cognitive ImpairmentMalignant NeoplasmThis randomized phase II trial studies how well low-dose ibuprofen in improving cognitive impairment in patients with cancer. Anti-inflammatory agents, such as ibuprofen, may slow the decline of cognitive processes and diseases involving the brain.

Exercise Periodization and Older Adults
AgingPhysical Activity4 moreThe present study aimed at investigating the effects of two different resistance training protocols - nonperiodized (NP) and daily undulating periodization (DUP) - on hemodynamic, morphofunctional and cognitive parameters of robust older women. Methods: Forty-two older women were randomized allocated into one of the three experimental groups: NP, DUP, and control group (CG). Evaluations of the hemodynamic, morphofunctional and cognitive parameters occurred before, during and after six months. The exercise groups performed the program of exercise twice a week over 22 weeks. In NP, the two weekly sessions were based on 3 sets of 8-10 repetitions at a difficult intensity. However, in DUP, a power exercise session based on 3 sets of 8-10 repetitions at a moderate intensity was added in the first session of the week.

Reversal of General Anesthesia With Methylphenidate
Post Operative Cognitive DysfunctionEmergence From AnesthesiaThe aim of this study is to investigate whether methylphenidate (Ritalin) can actively induce emergence from general anesthesia in patients having a pancreaticoduodenectomy (Whipple procedure), a pancreatectomy, or a prostatectomy.

Adaptive Cognitive Training in Healthy Older Adults
Mild Cognitive ImpairmentMild to Moderate Dementia1 moreCognitive training has emerged as a promising method to maintain, enhance, and rehabilitate cognitive function in older adults and individuals with dementia. In recent years, such training has become particularly appealing in the clinical context, with many paradigms aimed specifically at adults experiencing various stages of cognitive decline due to Mild Cognitive Impairment, Alzheimer's disease, and vascular dementias. However, basic questions remain. For example, uncertainty persists regarding factors that influence observed improvements as well as the conditions that would maximize transfer and sustainability of training effects. The objective of this study is to evaluate factors that may maximize the benefits of computerized cognitive training in older adults.

Vascular Mechanisms for the Effects of Loss of Ovarian Hormone Function on Cognition in Women
Cognitive ImpairmentExecutive Dysfunction2 moreComplaints 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.

Combined Transcranial Magnetic Stimulation and Cognitive Treatment in Blast Traumatic Brain Injury...
Traumatic Brain InjuryCognitive Dysfunction1 moreThis study investigates the efficacy of a novel neurorehabilitation program combining noninvasive brain stimulation (transcranial magnetic stimulation or TMS) and cognitive therapy, on cognitive function and quality of life in individuals with blast-induced traumatic brain injury (bTBI).

Pioglitazone Hydrochloride in Preventing Radiation-Induced Cognitive Dysfunction in Treating Patients...
Brain NeoplasmsMalignant5 moreRATIONALE: Pioglitazone hydrochloride may be effective treatment for cognitive dysfunction caused by radiation therapy. PURPOSE: This phase I trial is studying the side effects and best dose of pioglitazone hydrochloride in preventing radiation-induced cognitive dysfunction in treating patients with brain tumors.

Effects of Dietary Nitrate From Vegetable/Fruit Juice on Cerebral Blood Flow Parameters
Cerebrovascular CirculationCognitive ImpairmentNitrate provides the body with an alternative source of Nitric Oxide which plays a large role in promoting blood flow and reducing blood pressure. Nitrate supplementation with vegetable/fruit juice has recently been shown to reduce blood pressure and reduce energy expenditure during low intensity exercise. Such findings combined with the previously known biological effects of nitric oxide would suggest that nitrate supplementation would also impact on blood flow. The aim of this study is to examine the effects of dietary nitrate supplementation via vegetable/fruit juice drink on cerebral (brain) blood flow (using Near Infrared Spectroscopy).

Cerebral Oximetry and Neurocognitive Functions in Cardiosurgical Patients
Coronary Artery DiseasePostoperative Cognitive Dysfunction1 moreIt is previously reported that the cerebral oxygen desaturation during cardiac surgery is associated with an increased incidence of cognitive impairment. The aim of this study is to determine whether intraoperative monitoring and predetermined interventions protocol to improve cerebral oxygenation during coronary artery bypass surgery provides benefits in neurocognitive functions.
