This course focuses on stress reactions that result of exposure to war, combat, and related atrocities. You will learn about the diagnosis of PTSD, including its development and history. There is a strong emphasis on the neural and cognitive mechanisms for stress-related psychopathology, and the overlap of psychological and neural systems with the damaging effects of traumatic brain injury are studied. While the impact of these mechanisms on the social, interpersonal, and occupational is considered, this is not the focus of the course. To be fully prepared for this course, students should have a solid grounding in neuroscience and behavior, as well as basic psychopathology.
