Estradiol And Daily Affective Experiences In Trauma-Exposed Women, Jenna Rieder
Estradiol And Daily Affective Experiences In Trauma-Exposed Women, Jenna Rieder
Dissertations, Theses, and Capstone Projects
People who experience trauma can develop enduring trauma-related symptoms. In daily life, post-trauma symptoms (e.g., elevated physiological arousal) can be triggered by affectively salient cues in the environment, especially by cues that act as trauma reminders. Trauma exposure is associated with enduring changes in two biological stress systems: the sympathetic nervous system (SNS) and the hypothalamic-pituitary-adrenal (HPA) axis. In women, activity in both systems is additionally modulated by fluctuations in levels of sex hormones (e.g., estradiol), which could influence physiological responses to trauma reminders. Additionally, previous work has linked the sex hormone estradiol with affect, suggesting that menstrual cycle might …
Neural Hypervigilance In Trauma-Exposed Women, Seungyeon A. Yoon
Neural Hypervigilance In Trauma-Exposed Women, Seungyeon A. Yoon
Dissertations, Theses, and Capstone Projects
Trauma-exposed people often experience hypervigilance, which is a tonic condition of elevated alertness and excessive scanning for potential threat. A cardinal feature of hypervigilance is that no actual threat is needed to evoke or maintain the over-alertness and heightened affective response. However, most neuroimaging research in trauma to date has only focused on reactivity to an actual threat. Thus, the overarching aim of this dissertation was to investigate neural signatures and salivary markers of post-trauma hypervigilance in the absence of threat that can cause impairment in daily functioning and contribute to developing other trauma-related symptoms such as heightened threat reactivity. …
