Migraine of the basilaris type is a special form of the migraine. The symptoms of the aura can be clearly matched with the brain stem and/or both hemispheres simultaneously and no motoric deficiency occurs.
Migraine of the basilaris type often arises in young adults. Characteristic symptoms are speech impediment, dizziness, tinnitus, hearing impairment, double vision, impaired vision simultaneously of the temporal as well as the nasal field of vision of both eyes, ataxia, disturbance of consciousness or simultaneous bilateral paresthesia.
Very rarely, a locked-in syndrome occurs. Symptoms are complete paralysis but full consciousness for 2 to 30 minutes, sometimes vertical eye movements are possible (Bickerstaff-syndrome).
Most of the time, symptoms of the aura as well as the pain are felt on both sides.
