Dizziness/Vertigo/Imbalance
Dizziness/Vertigo/Imbalance are very common disorders and they can successfully treated if managed on time.
Vertigo (spinning sensation) and dizziness have a lifetime prevalence of almost 30% in the general population aged 18–79 years old. Dizziness due to vestibular dysfunction constitutes 2% of primary care physician consultation and is the most common cause of attendance in patients over 70 years of age.
Dizziness refers to an impairment in spatial perception and stability, with difficulties in maintaining balance at rest and whilst walking. It is often a chronic condition, recurrent or persistent, and commonly multifactorial. Although precisely diagnosing the underlying aetiology of dizziness is not always possible, vestibular tests can reveal the presence of a peripheral impairment, such as vestibular neuritis, Ménière’s Disease (MD), BPPV, Vestibular Migraine and presbyastasis. Dizziness may also be caused by central (eg. epilepsy, brainstem tumors, vascular insufficiency, multiple sclerosis) and general systemic causes (eg. cardiovascular diseases, musculoskeletal system disorders, drugs).
In addition, there is evidence that the persistence of dizziness due to vestibular disorders (lasting 6 months or more) may be related to the presence of psychological disorders and to cognitive impairment, therefore the need of treating these conditions promptly.
