• This case also featured oligemia in the left occipital cortex. (medscape.com)
  • Cortical spreading depression (CSD), recognized as the neuronal phenomenon underlying visual aura, is believed to begin in the occipital region and then gradually spread anteriorly. (medscape.com)
  • TGVS can be activated by cortical spreading depression (CSD), a phenomenon responsible for the aura. (nih.gov)
  • Changes in central nervous system flow that may induce a migraine attack may be associated with the occurrence of spreading cortical spreading depression (CSD). (nih.gov)
  • The concept of "cortical spreading depression (CSD)" has been accepted as the main pathogenetic mechanism of migraine aura. (j-stroke.org)
  • Our results support the controversial idea that waves of cortical spreading depression (SD) have a causal relationship with the headache phase in migraine and, therefore, occur not only in migraine with aura (MA), but also in migraine without aura (MO), i.e., in the two major migraine subtypes.

  • Cerebral oligemia starts in aura phase, spreads gradually anteriorly, and is followed by hyperemia in a MA attack [ 7 , 8 ]. (j-stroke.org)
  • They suggested that cellular edema or spreading depression could be responsible, not just ischemia. (medscape.com)
