Vertigo is a type of dizziness, where there is a feeling of motion when one is stationary. The symptoms are due to a dysfunction of the vestibular system in the inner ear. It is often associated with nausea and vomiting as well as difficulties standing or walking. The most common causes are benign paroxysmal positional vertigo, concussion and vestibular migraine while less common causes include Ménière's disease and vestibular neuritis. Excessive consumption of ethanol can also cause notorious symptoms of vertigo. (For more information see Short term effects of alcohol)...
