Posterior circulation stroke (PCS) makes up 20–40% of all strokes. Although PCS is less common than anterior circulation stroke (ACS), it is important to be familiarized with the risk factors, stroke mechanisms, and presenting features of PCS because they are less well recognized than those of ACS. In this chapter, we explore the prevalence, risk factors, and stroke mechanism of PCS. In addition, we attempt to answer the question as to whether or not there are differences in the risk profiles and stroke mechanisms between PCS and ACS. Understanding this difference will help physicians to diagnose and treat patients with PCS appropriately.
