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]
Medical treatment with anti-vertigo medications may be considered in acute, severe exacerbation of BPPV, but in most cases are not indicated. These primarily include drugs of the antihistamine and anticholinergic class, such as meclizine [9] and hyoscine butylbromide (scopolamine), respectively. The medical management of vestibular syndromes ...
Some over-the-counter as well as prescription drugs and certain industrial chemicals are ototoxic. Exposure to these can result in temporary or permanent hearing loss. Some medications cause irreversible damage to the ear, and are limited in their use for this reason. The most important group is the aminoglycosides (main member gentamicin). A ...

One of the challenges is that symptoms of stroke in women have a number of overlapping symptoms with migraine. For example, both severe migraine and stroke may cause vision changes and dizziness.
Many inner ear disorders can cause dizziness, which leads to dysfunctional righting reflex action. Common inner ear disorders can cause vertigo in patients, which can be acute or chronic symptoms. [1] Labyrinthitis, or inflammation of the inner ear, can cause imbalances that must be overcome through therapeutic exercises.
Noise exposure is the cause of approximately half of all cases of hearing loss, causing some degree of problems in 5% of the population globally. [5] The National Institute for Occupational Safety and Health (NIOSH) recognizes that the majority of hearing loss is not due to age, but due to noise exposure.
Ototoxicity of gentamicin can be exploited to treat some individuals with Ménière's disease by destroying the inner ear, which stops the vertigo attacks but causes permanent deafness. [19] Due to the effects on mitochondria, certain inherited mitochondrial disorders result in increased sensitivity to the toxic effects of aminoglycosides.
