Neuroimaging and Neurobehavioral Basis of Risky Decision Making in Adolescents

Many older adolescents (18-24 yrs. old) engage in high-risk behaviors such as unprotected sex, multiple sex partners, and drug use. HIV+ adolescents may continue to engage in high-risk behaviors. It is imperative that early markers of risky behaviors are identified so effective interventions are implemented to reduce HIV transmission. This project will utilize non-invasive neuroimaging to quantitatively measure cerebral blood flow (CBF) within risky decision-making networks. Preliminary studies have demonstrated that HIV diminishes CBF by 60% within risky decision-making areas. We will also use computer based neurobehavioral tests that simulate real-life risky decision making situations. This research will: 1) increase our knowledge concerning the interaction between risky decision-making and HIV in adolescents, 2) provide development of early neuroimaging and neurobehavioral markers that assess the impact of HIV infection on risky decision- making networks and 3) assist nurses, clinicians, and public health practitioners in developing interventions.

Traumatic Stress: New Mechanisms and Effective Treatment

The impacts of a physical trauma are well understood in the medical community, and treatment approaches have become quite advanced. Our ability to study the brain and its reactions to physical and chemical stimuli is relatively new, but growing at incredible speeds. "Traumatic Stress: New Mechanisms and Effective Treatment" will bring together a group of internationally recognized researchers to deliver a whole new perspective on what physically happens in the brain during and following traumatic stress. They will explore not only the physical, but the behavioral and emotional reactions to traumatic stress through the lens of groundbreaking new research. Most importantly, they will offer a fresh perspective on care and treatment. This conference will change how you look at traumatic stress in the brain and what to do about it.
