The NIAC Seminar Series welcomes Colin Derdeyn, Ph.D.
“Cerebral Hemodynamics and Stroke Risk”
There are several diseases and disorders that affect the normal delivery of oxygen to brain tissue. The major consequence of these conditions is ischemic stroke. These diseases and disorders include arterial occlusive diseases such as atherosclerosis, Moyamoya phenomenon, subarachnoid hemorrhage-induced vasospasm, and other conditions such as anemia.
The effects on brain blood flow, oxygen extraction and oxygen metabolism can be uniquely studied with positron emission tomography. This line of inquiry has been a major focus of investigators in the Neuro Imaging Lab for almost 40 years and it remains important today.
The talk today will focus on cerebral hemodynamics – the responses of the brain and brain vasculature to reduced tissue oxygen delivery and the relationship to stroke risk.
