Filter by:In the landmark Boston Circulatory Arrest Study, neurologic and developmental status was measured following infant heart surgery and then prospectively at ages 1, 2.5, 4, 8, and 16 years, with findings of significant neurocognitive deficits and brain MRI abnormalities regardless of operative management. To date, no study has evaluated the neuropsychological and neuroimaging antecedents and correlates of well-being in adults with congenital heart disease, a population now >1 million and projected to grow at 5% per year. The investigators propose to study the Boston cohort at ages 24-29 years to assess the associations of adult well-being with childhood and adolescent executive function, other measures of mental health and cognitive function, adolescent brain MRI findings, and clinical variables; findings will guide the design of interventions in childhood to optimize outcomes in adults with congenital heart disease.
The purpose of this study is to assess the effect of playing high school football on later in life cognitive functioning and mental health. This is an observational study that will use data from the Wisconsin Longitudinal Study to compare high school football playing graduates in 1957 with comparable non-high school football playing graduates on cognitive functioning and mental health measures when participants are in their 60s.
This study aims to test the efficacy of a type of non-invasive brain stimulation (NIBS), known as repetitive transcranial magnetic (rTMS) stimulation, in improving mobility, particularly gait stability and variability, and executive dysfunction in older adults. The study will be conducted in forty older adults (≥60 years) with a diagnosis of executive dysfunction.
Patients with mild-moderate traumatic brain injury (TBI) sustained between 3 months and 5 years ago with prolonged postconcussive symptoms will be recruited. On Day 1 of the study they will undergo neuropsychological (NP) testing. They will then undergo 10 days of Left dorsolateral prefrontal (DLPFC) anodal transcranial direct current stimulation (TDCS) (active or sham) combined with cognitive training. On day 10 NP testing will be obtained again. On Day 30, NP testing will be repeated a 3rd time. At 6 months and 1 year, quality of life, depression, and post concussive symptoms will be assessed.
This doctoral thesis has the aim to identify the role of Brain-derived neurotropic factor in the relationship between physical fitness/activity and executive functions in typically developing children and children with Autism Spectrum Disorder, Development Coordination Disorder , Attention Hyperactive Disorder.
Diabetes increases the risk of cognitive dysfunction. The incidence of dementia is 1.5 to 2.5 times higher in persons with diabetes than the general population. There is evidence that cognitive decline significantly impacts the ability to self-manage diabetes. Strategies to prevent cognitive decline in persons with diabetes has not been well studied. A recent study reported that in persons who had vitamin D deficiency, the risk for all-cause dementia and Alzheimer's was doubled. Vitamin D receptors are located in the brain and deficiency of vitamin D has been reported to negatively affect the development of brain. Therefore, providing vitamin D supplementation to improve cognitive function is worthy of study. The investigators propose a small, randomized controlled trial to determine the effects of vitamin D3 supplementation in persons with type 2 diabetes who have symptoms of cognitive impairment. Persons will be randomized to receive either weekly vitamin D3 supplementation (50,000 IUs) or a matching comparator (5000 IUs) for a period of three months. The study aims are to determine (1) the effect of vitamin D3 supplementation on cognitive function and (2) the effect of vitamin D3 supplementation on diabetes self-management. A sample of persons with type 2 diabetes (n=62), who have a subjective complaint of a cognitive dysfunction or scoring at least one standard deviation below normal on a cognitive functioning screening test, have vitamin D levels less 30 ng/ml, are not depressed (as this impacts cognitive function), and do not have severe diabetes complication will be recruited. Participants will be phone screened and complete two baseline visits prior to randomization. They will then have phone call and follow-up visits to assess (1) cognitive function using standardized tests to assess for executive function (2) serum measurements (HBA1c, fasting glucose, vitamin D levels, and cardiometabolic profile) and (3) surveys to assess cognitive function as well as self-management behaviors.
The aim of this study was to evaluate and compare the effects of Atomoxetine(ATX) and osmotic release oral system-methylphenidate (OROS-MPH) therapies on executive functions, activities, treatment response time and adverse effects based on discernible clinical effects in children with combined type attention deficit-hyperactivity disorder (ADHD).
This study aims to evaluate the effect of stimulation of prefrontal regions on language performance (e.g. word translation and picture naming). During the language tests, cortical activity will be registered using electroencephalography (EEG) which will provide supplementary information about the cerebral processus involved in language production and management of two languages in bilingual subjects.
This project will develop and evaluate the initial effectiveness of an intervention training executive functioning, metacognition, and self-regulation in preschoolers attending certain high poverty Cincinnati preschools. Studies show that these skills are critical for school performance, and that children with better executive functioning have better long term outcomes. It is also important to intervene early when children are most likely to profit because their brains are rapidly developing. There are some promising programs targeting these skills in preschoolers, but few are available to teachers for implementation in the classroom setting. The specific aims of this study are: 1) to adapt a promising clinic-based program for the preschool classroom environment, and 2) to test the feasibility and initial impact of the adapted program on executive functioning and school readiness in schools with a high proportion of children from low income families.
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.
