Just as migraine visual aura causes vision changes, sensory aura causes changes in the other senses.
Sensory aura symptoms are typically short lived, lasting only a few minutes up to an hour on average. Most patients say the sensory aura symptoms gradually spread from one part of the body to another. Sometimes this is called a “march” of symptoms. For example, the symptoms may begin in the tips of the fingers and slowly start to spread throughout the arm and then on to another body part.
Slightly more than one-tenth of migraine sufferers complain of sensory aura. The symptoms of sensory aura usually include numbness, tingling and other “odd” sensations in the limbs, face or throughout the body.
What causes sensory aura?
There is no confirmed reason for the symptoms seen in sensory aura. Some researchers believe that sensory aura is caused by improper functioning the area of the brain stem responsible for keeping the senses under control.
