Vertigo (Dizziness) is chiefly manifested as dizziness and blurred vision, which usually occur simultaneously. The mild case can be relieved by closing one's eyes; while the serious one has a rotatary sensation like sitting in a sailing boat or moving car, difficulty in standing firmly and accompanying symptoms such as nausea, vomiting, sweating and pale complexion.

Head injuries may increase the risk of developing vertigo, as can different medications, including some antiseizure medications, blood pressure medications, antidepressants, and even aspirin. Anything that may increase your risk of stroke (high blood pressure, heart disease, diabetes, and smoking) may also increase your risk of developing vertigo. For some people, drinking alcohol can cause vertigo. Studies of the incidence of vertigo find that between 2% to 3% of a population is at risk of developing BPPV; older women seem to have a slightly higher risk of developing this condition.
