The Signs and Causes of the Vertigo
Waves, bowling a hoop, running and all circular movement are possible causes of the vertigo. The proximate cause is a warm and tenuous vapour which so acts on the brain and senses that one is seized with vertigo and collapses unless falling is prevented by a wall or other nearby body. And it is considered to originate in the brain when the vision is dimmed, the hearing impaired, the ears have tinnitus, smell and taste are defective, headache oppressive and the mind overcome with drowsiness. But the disorder arises from the lower parts if there is nausea and stomach-ache and distaste for any food that is served: and the patient complains that everything seems to be going round.
