There are two types of vertigo — peripheral and central — and each has a different cause. Peripheral vertigo is caused by a problem in the part of the inner ear that controls balance. (This is ...
Vertigo that arises from injury to the balance centers of the central nervous system (CNS), often from a lesion in the brainstem or cerebellum, [9] [15] [19] is called "central" vertigo and is generally associated with less prominent movement illusion and nausea than vertigo of peripheral origin. [20] Central vertigo may have accompanying ...
Dizziness is a common medical complaint, affecting 20–30% of persons. [4] Dizziness is broken down into four main subtypes: vertigo (~25–50%), disequilibrium (less than ~15%), presyncope (less than ~15%), and nonspecific dizziness (~10%). [5] Vertigo is the sensation of spinning or having one's surroundings spin about them. Many people find ...
Causes of dizziness related to the ear are often characterized by vertigo (spinning) and nausea. Nystagmus (flickering of the eye, related to the Vestibulo-ocular reflex [VOR]) is often seen in patients with an acute peripheral cause of dizziness.

Each episode of vertigo typically lasts less than one minute. [3] Nausea is commonly associated. [7] BPPV is one of the most common causes of vertigo. [1] [2] [8] BPPV is a type of balance disorder along with labyrinthitis and Ménière's disease. [3] It can result from a head injury or simply occur among those who are older. [3]
The cause is often not clear. It may be due to a virus, but it can also arise from bacterial infection, head injury, extreme stress, an allergy, or as a reaction to medication. 30% of affected people had a common cold prior to developing the disease. [1] Either bacterial or viral labyrinthitis can cause a permanent hearing loss in rare cases. [7]
Many people experience lightheadedness or dizziness at some point in their lifetime, but if you are living with a neurodegenerative condition, like Parkinson’s disease, those symptoms could mean ...
Reflex syncope can occur in otherwise healthy individuals, and has many possible causes, often trivial ones such as prolonged standing with the legs locked. [citation needed] The main danger of vasovagal syncope (or dizzy spells from vertigo) is the risk of injury by falling while unconscious.
