Although decreases in regional cerebral blood flow are knownto occur in relation to migraine headache, the pattern of thealterations in blood flow has not been precisely delineated.Olesen et al. have described a series of patients who had migraineheadaches during serial cerebral blood-flow measurement by theintracarotid xenon-133 technique.1 They observed a pattern oflocalized decreases in flow that appeared to spread contiguouslyalong the cerebral cortex. These observations were confirmedin subsequent studies,2,3 and with very few exceptions1,4 thepattern of "spreading oligemia" or "spreading hypoperfusion"5has been apparent only in patients who have migraine headaches. . .
