Neuroanatomy In Mild Cognitive Impairment: Relationship To Functional Skills, Treatment Expectancy, And Comorbid Depression, Sara Rushia
Dissertations, Theses, and Capstone Projects
Mild cognitive impairment (MCI) is a neurocognitive disorder defined by cognitive decline in older adults. Although MCI has been studied for decades, there remain important areas to be explored in order to adequately characterize aspects of this disorder that provide information valuable for possible interventions and disease progression to dementia, including a better understanding of the neuroanatomical variables relevant to this disorder. Such neuroanatomical variables include cortical thickness, hippocampal volume, and white matter hyperintensities (WMHs). This dissertation consists of three separate studies aimed at addressing gaps in the literature on MCI in relation to brain morphometrics and under-studied characteristics involved …
Using Motor Imagery As An Alternative To Exercise For Improvement Of Mental Health: A Qualitative Investigation, Madelyn Colbert
Using Motor Imagery As An Alternative To Exercise For Improvement Of Mental Health: A Qualitative Investigation, Madelyn Colbert
Spectra Undergraduate Research Journal
Exercise is a commonly used non-pharmacological treatment to improve the mental and physical health of patients with varying conditions. However, not all patients have the means to participate in exercise and/or physical exertion. Motor imagery training (MIT) is visualizing a task without motor output. Evidence has demonstrated MIT to enhance physical function with and without adjacent physical practice. A qualitative research study was conducted to examine the effectiveness of utilizing MIT as a depression and anxiety reducing alternative to exercise. Seven participants meeting the selection criteria were randomized into (a) the exercise group, or (b) the MIT group. The three …
Cortisol Administration Normalizes Aberrant Functional Connectivity In Women With Depression, Adam C. Runyan
Cortisol Administration Normalizes Aberrant Functional Connectivity In Women With Depression, Adam C. Runyan
Dissertations
Previous resting-state functional connectivity (rsFC) research has identified aberrant connectivity in several large brain networks in depression, including the default mode (DMN), frontoparietal (FPN), and salience networks (SN). Connectivity of these networks is also related to depressive symptom severity and is affected by cortisol levels. To our knowledge, this is the first study to investigate the effects of acute cortisol administration on rsFC of DMN, FPN, and SN in individuals varying in depression history and severity. We collected resting-state fMRI scans for 74 women with and without a history of depressive disorder after administration of cortisol and placebo using a …
Effort-Related Motivational Dysfunctions: Behavioral And Neurochemical Studies Of The Wistar-Kyoto Rat Model Of Depression, Brendan Abbott
Effort-Related Motivational Dysfunctions: Behavioral And Neurochemical Studies Of The Wistar-Kyoto Rat Model Of Depression, Brendan Abbott
Masters Theses
Depression and related disorders are characterized by motivational dysfunctions, including deficits in behavioral activation and exertion of effort. Animal models of relevance to depression represent a critical starting point in elucidating the neurobiological mechanisms underlying motivational dysfunctions. The present study explored the use of the Wistar-Kyoto (WKY) animal model of depression to examine effort-related functions as measured by voluntary wheel running and performance on a mixed fixed ratio 5/progressive ratio (FR5/PR) operant task. Given the known link between activational aspects of motivation and the mesocorticolimbic dopamine (DA) system, the behavioral effects of d-amphetamine (0.5 and 1.0 mg/kg, IP), a psychostimulant …
Slam Poetry: An Online Intervention For Treating Depression, Spencer J. Ruchti, Mercedes Becker, Cara Mckee, Austin Herron, Alex Swalling
Slam Poetry: An Online Intervention For Treating Depression, Spencer J. Ruchti, Mercedes Becker, Cara Mckee, Austin Herron, Alex Swalling
Undergraduate Theses, Professional Papers, and Capstone Artifacts
Given that depression is the “leading cause of disability worldwide,” and that less than 50% of people suffering from depression receive treatment, this study aims to provide support for a globally accessible depression treatment (WHO, 2012). The study conducted implemented an internet-based treatment for depression in which users were provided an opportunity to watch slam poetry videos related to mental health issues and write free responses regarding the content of the videos and their subjective experience of depression. Numerous studies provide support for the effectiveness of expressive writing, online mental health interventions, and slam poetry in particular for reducing symptoms …
The Effects Of Pet Ownership On Anxiety And Depression Among Trauma-Exposed College Students, Dung N. Nguyentran, Marlene A. Michniak, James J. Jung, Christine Q. Do
The Effects Of Pet Ownership On Anxiety And Depression Among Trauma-Exposed College Students, Dung N. Nguyentran, Marlene A. Michniak, James J. Jung, Christine Q. Do
Undergraduate Research Posters
Rates of anxiety and depression are prevalent in college students and can be attributed in part to stress and trauma-related events. However, studies suggest that pet ownership has the possibility of alleviating symptoms of anxiety, depression, negative emotions, and suicide. The purpose of this study was to determine the relationship between pet ownership and levels of anxiety and depression among those who have experienced a traumatic event. The sample was comprised of five hundred and forty-seven VCU students who completed an online survey from Spit for Science during their junior year. Linear regressions were performed to determine the nature and …
