Classification[ edit ] Vertigo is classified into either peripheral or central depending on the location of the dysfunction of the vestibular pathway,  although it can also be caused by psychological factors. Objective vertigo describes when the person has the sensation that stationary objects in the environment are moving. While this classification appears in textbooks, it has little to do with the pathophysiology or treatment of vertigo. Motion sickness is sometimes classified as a cause of peripheral vertigo.

Hearing loss can fluctuate, especially early on in the disease. There may also be a sensitivity to loud sounds. Eventually, most people experience some degree of long-term hearing loss. This involves sudden and unpredictable episodes of vertigo.
Episodes last from 20 minutes to 24 hours. During episodes, there will be some hearing loss, which returns to normal after it is over. The ear may feel uncomfortable and blocked, with a sense of fullness or pressure.
Tinnitus is also common. Vertigo episodes continue but are usually less severe. Tinnitus and hearing loss get worse. During this stage, some people will experience periods of complete remission where symptoms disappear. These periods of remission can last several months. Vertigo episodes become even less frequent, and in some cases never come back.
Balance problems, though, can continue. Individuals will feel especially unsteady when it is dark. Hearing and tinnitus normally get steadily worse. The following symptoms are also possible. These are known as secondary symptoms: The disease can have an impact on the individual's work, especially if they have to climb ladders or operate machinery.
As hearing gets progressively worse, they may find it more difficult to interact with other people. Some people cannot drive, further limiting their independence, job prospects, freedom, and access to friends and family.

However, hypocapnia causes cerebral vasoconstriction, leading to cerebral hypoxia and this can cause transient dizziness, visual disturbances, and anxiety.A low partial pressure of carbon dioxide in the blood also causes alkalosis (because CO 2 is acidic in solution), leading to lowered plasma calcium ions and increased nerve.
Vertigo is recorded as a symptom of decompression sickness in % of cases by the US Navy as reported by Powell, It including isobaric decompression sickness..
