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 …
Threat-Related Attentional Bias In Relation To Anxiety And Depressive Symptoms In The General Population: The Potential Role Of Sex Effects, Beril Yaffe
Dissertations, Theses, and Capstone Projects
Heightened sensitivity to relevant environmental stimuli (attentional bias) has been observed in relation to clinical and non-clinical anxiety and depression symptoms. While depression symptoms are associated with sensitivity to disorder and self-relevant words, hypervigilance to threatening stimuli is observed in relation to anxiety symptoms. Furthermore, attentional bias has been shown to play an important role in the development and maintenance of depressive and anxiety disorders. Accordingly, a large body of literature has examined threat-related attentional bias in relation to symptoms of anxiety and depression. However, several methodological inconsistencies exist across studies, including variability in definitions of threat, lack of consideration …
