Cerebral Blood Flow

Using an MRI technique called arterial spin labeling, this New Jersey group compared blood flow in thecerebral-blood-flow brains of 11 subjects with CFS and 10 age-matched healthy controls. The CFS patients as a group had significantly lower global cerebral blood flow (CBF) compared to controls. The reduction in CBF occurred across nearly every region assessed. Nine of the 11 patients showed these reductions compared to the average control data, while two patients showed actual increases relative to the controls.
