Answer

Paresthesias, occurring in 40% of cases, constitute the next most common aura; they are often cheiro-oral, with numbness starting in the hand, migrating to the arm, and then jumping to involve the face, lips, and tongue. As with visual auras, positive symptoms typically are followed by negative symptoms; paresthesias may be followed by numbness.

Sensory aura rarely occurs in isolation and usually follows visual aura. The rate of spread of sensory aura is helpful in distinguishing it from transient ischemic attack (TIA) or a sensory seizure. Just as a visual aura spreads across the visual field slowly, paresthesias may take 10-20 minutes to spread, which is slower than the spread of sensory symptoms of TIA.
