In patients without MS, the blood flows from the brain, to the spinal chord to the heart without changing direction. The doppler machine detects this, showing up as blue in the video. Untreated MS patients are the opposite. Blood flows towards the brain rather than towards the heart. In the video, the doppler detects this as red spots showing on the monitor. The effects of MS may be altered when a balloon is inserted into the vein, restoring normal blood flow, but first a test must be performed.
