Problems with balance can occur when there is a disruption in any of the vestibular, visual, or proprioceptive systems. Abnormalities in balance function may indicate a wide range of pathologies from causes like inner ear disorders, low blood pressure, brain tumors, and brain injury including stroke. [citation needed]
Vestibulopathies are disorders of the inner ear. 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.
The most common vestibular diseases in humans are vestibular neuritis, a related condition called labyrinthitis, Ménière's disease, and BPPV. In addition, the vestibular system's function can be affected by tumours on the vestibulocochlear nerve , an infarct in the brain stem or in cortical regions related to the processing of vestibular ...
The root cause of the process is unclear and may vary from patient to patient, but can have auto-immune, viral, and/or allergic triggers, among others. [2] The build-up of endolymph creates pressure in the scala media. This causes its diameter to increase, and the vestibular membrane to curve outwards in the direction of the vestibule. The ...
Generally referred to as a form of decompression sickness, it can also occur at constant pressure due to inert gas counterdiffusion effects. [1] Usually only one side is affected, and the most common symptoms are vertigo with nystagmus, loss of balance, and nausea.
Thus dizziness can be caused by a variety of problems and may reflect a focal process (such as one affecting balance or coordination) or a diffuse one (such as a toxic exposure or low perfusion state). [8] Common causes of dizziness include: Inadequate blood supply to the brain due to: A sudden fall in blood pressure [7]

Balance can be upset by Ménière's disease, superior canal dehiscence syndrome, an inner ear infection, by a bad common cold affecting the head or a number of other medical conditions including but not limited to vertigo. It can also be temporarily disturbed by quick or prolonged acceleration, for example, riding on a merry-go-round. Blows can ...
