What is a complex migraine?

A complex migraine (also known as a complicated migraine), is a type of migraine that involves neurological symptoms, in addition to the typical migraine symptoms like a throbbing head pain, nausea and sensitivity to light and sound.

The neurological symptoms associated with a complex migraine can include visual disturbances, such as:

  • Flashing lights
  • Zig zag lines
  • Blind spots
  • Difficulty speaking or understanding (also known as aphasia)
  • Ringing in the ears
  • Weakness or numbness on one side of the body
  • Dizziness / vertigo
  • Disorientation.

Complex migraines are considered a subtype of migraine with aura, which means they are preceded by a warning sign or aura, typically visual.

However, unlike typical migraine with aura, complex migraines may involve more severe and prolonged symptoms that can last for many hours or even days.
