Dizziness, coupled with the sensation of spinning, rocking back and forth; often causing motion sickness (nausea, vomiting). Often mistaken as Meniere’s Disease, the damage a Chiari Malformation does to the cerebellum can cause episodes of spontaneous vertigo; however, if vertigo becomes acute, signs of hydrocephalus should be ruled out.

A drug that treats or prevents nausea and vomiting.
