Any cause of inflammation such as common cold and influenza cause transient vertigo if it involves the inner ear.
  • Central vertigo – It occurs when the underlying cause lies within the central nervous system of the body. It includes the movement illusion which is not so prominent and nausea instead of a typical peripheral vertigo. It can be caused due to hemorrhage or infractions, tumors like vestibular schwannoma or cerebellar tumors.

Central vertigo also consists of neurologic defects like slurred speech and double vision with pathologic nystagmus.
