A migrainous aura is normally a "prodomal" symptom, occurring prior to the
onset of a migraine itself. The aura consists of neurological symptoms that normally
develop slowly and subside slowly. These neurological symptoms can consist of (a
comprehensive list of symptoms will go here).
If the aura is followed or accompanied by a migraine headache, the headache is then
called a "classic migraine" or "migraine with aura." If, however, the
aura subsides and no headache ensues, the episode is then called a "migraine
equivalent."
