Vascular vertigo
Vascular vertigo is mostly associated with the lack of blood supply to certain areas in the brain, which causes various vestibular syndromes.
These syndromes are usually associated with vertigo and may sometimes be misdiagnosed as pre-stroke symptoms and sometimes as migraine.
Decompression sickness in deep-sea divers sometimes has symptoms of vascular vertigo syndrome. Confusion and vertigo during diving trips could be a result of this.
• Traumatic vertigo
Head injuries from motor vehicle accidents or any other kind of trauma would result in traumatic vertigo. The site of injury is in the inner ear, including damage to the balance nerve. Divers and mountain climbers suffer this kind of vertigo due to barotraumas, which is a result of pressure change.
In both high and low-pressure environment, the inner ear can be damaged due to sudden rupture of the inner membranes.
