Types of Vertigo
It can be classified into two depending on where the dysfunction is located.
• Peripheral-When the problem occurs in the inner parts of the ear or sensory system it is known as otologic, vestibular or peripheral. BPPV (Benign paroxysmal positional vertigo) is the most common cause. Superior canal dehiscence syndrome, Ménière's disease, visual vertigo and labyrinthitis are the other causes.
• Central- When the parts of the brain which controls balance causes vertigo, it results in neurological deficits like slurred speech, pathologic nystagmus or double vision. It can create a sense of disequilibrium. Migraine headaches, multiple sclerosis, lateral medullary syndrome and other conditions which engages the central nervous system can also cause vertigo.
