14-30% of migraine in children is of this variety. The aura may follow premonitory symptoms and may or may not be followed by headache.
- The aura may suggest cortical dysfunction (visual, sensory, motor, speech or language disturbance, cognitive impairment including confusion), or brainstem dysfunction (loss of consciousness, vertigo).
- Children may find it difficult to describe the aura.
- The aura is often more distressing than the headache in children.
- Visual auras are the most common (blurred vision, fortification spectra, scotomata, micropsia, macropsia, dysmorphopsia, etc.).
- Children who eventually develop migraine with aura usually present earlier than children experiencing migraine without aura.
