Nausea and vomiting usually occur later in the attack in about 80% and 50% of patients, respectively, along with anorexia and food intolerance. Some patients have been noted to be pale and clammy, especially if nausea develops. Photophobia and/or phonophobia also commonly are associated with the headache. Lightheadedness is frequent. See Migraine-Associated Vertigo for more information on migraine-related vestibulopathy.

Other neurologic symptoms that may be observed include the following:

  • Hemiparesis (this symptom defines hemiplegic migraine)

  • Aphasia

  • Confusion

  • Paresthesias or numbness
