Effect Of Progesterone On Cognition Among College Aged Women, Katelyn Helberg
Effect Of Progesterone On Cognition Among College Aged Women, Katelyn Helberg
Biological Sciences Undergraduate Honors Theses
Women who have a reoccurring menstrual cycle and do not take hormonal birth control naturally experience changes in the amount of sex hormones that their body produces. These sex hormones help promote sexual development, fertility, and mood regulation, but can be hard to study due to their conflicting effects on each other. One such hormone, progesterone, is produced in different concentrations throughout the menstrual cycle to prepare the uterus for a potential pregnancy. However, it also may have secondhand effects on how well women can complete everyday tasks involving memory, attention, processing speed, and more which is what we measured …
The Effects Of Physical Function And Genetics On Cognition And Blood Biomarkers In Individuals At-Risk For Alzheimer’S Disease And Related Dementias, Joshua Louis Gills
The Effects Of Physical Function And Genetics On Cognition And Blood Biomarkers In Individuals At-Risk For Alzheimer’S Disease And Related Dementias, Joshua Louis Gills
Graduate Theses and Dissertations
Alzheimer’s disease and related dementia (ADRD) rates are expected to triple by the year 2050. Early detection and specific mitigation efforts are warranted to blunt the alarming rate. Physical function (PF) declines with age, but higher physical function is associated with better cognitive functioning in middle-to- older age individuals. Moreover, greater physical activity (PA) is associated with better global cognition; however, Apoliporotein e4 carriers may not gain the same benefits with exercise. Additionally, plasma phosphorylated tau 217 (p-tau217) has been identified as a novel diagnostic ADRD biomarker which needs further research to examine associations with risk factors. Therefore, the aims …
Negative Urgency's Influence On State-Level, Emotion-Based Changes In Alcohol-Related Cognitions, Noah Wolkowicz
Negative Urgency's Influence On State-Level, Emotion-Based Changes In Alcohol-Related Cognitions, Noah Wolkowicz
Graduate Theses and Dissertations
This project expanded on the Acquired Preparedness Model of Risk (APMR) by examining how Negative Urgency (NU), the tendency to act rashly in negative emotional states, affects emotion-based changes in alcohol cognitions to produce risk for alcohol use. The APMR prioritizes the role of outcome expectancies as the means through which traits such as NU, convey alcohol use risk. However, this model treats these cognitions as static and often fails to assess their valence; further, alcohol-cognitions fluctuate in response to negative emotions and may become more salient during these states. Therefore, this study examined: 1) how NU impacts negative emotion-based, …
Relationship Between Global Cognition And Cardiovascular Risk Factors, Alexia Sebghati
Relationship Between Global Cognition And Cardiovascular Risk Factors, Alexia Sebghati
Health, Human Performance and Recreation Undergraduate Honors Theses
Alzheimer’s disease (AD) is currently affecting the lives of 5.8 million Americans and is expected to double within the next 30 years. With an aging populace of baby boomers, this will place great economic strain on the U.S. creating a burden of almost $1 trillion in healthcare costs. Currently, there is no cure for AD. However, studies report that many individuals with AD experience changes in the brain up to 10-15 years before the disease’s onset. It is imperative to detect future risk of developing AD or mild cognitive impairment (MCI) before significant cognitive changes arise. Many of the risk …
The Acute Effects Of Caffeine And L-Theanine On Cognition In Older Adults, Lauren Tilley
The Acute Effects Of Caffeine And L-Theanine On Cognition In Older Adults, Lauren Tilley
Health, Human Performance and Recreation Undergraduate Honors Theses
The acute effects of L-theanine and Caffeine on cognition in older adults
Tilley, L., Gray, M., Stone, M., & Binns, A.; Human Performance Lab; University of Arkansas; Fayetteville, AR.
Introduction: Cognitive decline is an impairment that affects many adults and has the potential to be decelerated. Previous studies show that caffeine and L-theanine positively affect cognition in a young population. L-theanine is an amino acid found in tea that produces a relaxation affect. Therefore, the purpose of this study is to determine the acute effects of caffeine and L-theanine on cognition in older adults. Methodology: Fifty-three older adults …
The Effects Of Hypohydration On Neurocognitive, Balance, Vestibular Ocular Motor Functions And Mood State, Satoshi Iida
The Effects Of Hypohydration On Neurocognitive, Balance, Vestibular Ocular Motor Functions And Mood State, Satoshi Iida
Graduate Theses and Dissertations
Inconsistent findings have been observed on the impact of hydration state on cognitive functions. The isolated effect of hypohydration on neurocognitive performance, balance, vestibular ocular motor function and mood outcomes in widely used concussion assessment tools has not been studied. The purpose of this study was to investigate how hypohydration affected the results in concussion testing batteries. A single-blind randomized crossover design was used. Thirteen healthy males (22 ± 4y, 180.9 ± 5.7cm) without history of concussion within the past six months or any condition or disease that could influence outcome measurements participated in this study. Each subject completed concussion …
Is The Geriatric Impact Ipad Test A Valid Measurement Of Cognitive Function In Older Adults?, Heather Elise O'Dell
Is The Geriatric Impact Ipad Test A Valid Measurement Of Cognitive Function In Older Adults?, Heather Elise O'Dell
Graduate Theses and Dissertations
The number of older adults will rapidly increase within the next generation (Brookmeyer, Johnson, Ziegler-Graham, & Arrighi, 2007). Alzheimer’s disease risk increases with age, especially after age 60 (NIA, n.d.). Aging leads to a decrease in functional independence, and this side effect is exacerbated by cognitive decline (Johnson, Lui, & Yaffe, 2007). Executive function is a predictor of Alzheimer’s disease onset and progression (Zhang, Han, Verhaeghen, & Nilsson, 2007). The Geriatric ImPACTTM test is a potential new and more convenient testing methods than traditional methods used. The purpose of this research is to validate the Geriatric ImPACTTM test by comparing …
