In addition to the neuronal and behavioral consequences of excess glucocorticoid exposure, the cerebrovascular system can also be adversely affected by stressors. This study determined that chronic stress in adulthood decreased the vascular area fraction of the hippocampus and increased the vascular area fraction of the amygdala. In addition, the data indicated that prenatal exposure to synthetic glucocorticoids modulated the effects of adult stress on vascular area fraction of the hippocampus and amygdala. These data indicate that in addition to the well-documented stress-induced changes in neurons and glia, cerebral vasculature is also altered by exposure to stressors.
