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 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 vertigo very disturbing and often report associated nausea and vomiting. [6]
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.

Symptoms are repeated, brief periods of vertigo with movement, characterized by a spinning sensation upon changes in the position of the head. [1] This can occur with turning in bed or changing position. [3] Each episode of vertigo typically lasts less than one minute. [3] Nausea is commonly associated. [7] BPPV is one of the most common causes ...
PAN II will eventually cause subjective vertigo in the opposite direction. This occurs several hours after ingestion and after a relative reduction in blood alcohol levels. [citation needed] Benign paroxysmal positional vertigo (BPPV) is a condition resulting in acute symptoms of vertigo. It is probably caused when pieces that have broken off ...
Benign paroxysmal positional vertigo (BPPV) is the most common cause of peripheral vertigo. [2] It can be characterized by three main symptoms: positional onset, spinning dizziness and short-lived symptoms. The primary diagnostic maneuver is the Dix-Hallpike which elicits the cardinal sign associated with BPPV, rotatory nystagmus.
They may include bilateral vestibulopathy, [1] central vestibulopathy, [2] post traumatic vestibulopathy, [3] peripheral vestibulopathy, [4] recurrent vestibulopathy, [5] visual vestibulopathy, [6] and neurotoxic vestibulopathy, [7] among others. Tinnitus is a common vestibulopathy. Migraines have often been associated with vestibulopathies.
