Chronic dizziness can be a debilitating symptom, often requiring a multidisciplinary approach to determine whether the cause is neurological, cardiovascular, or related to the inner ear.
From Middle English disynes, duysenes, from Old English dysiġnes (“dizziness, folly, foolishness, blasphemy”), equivalent to dizzy + -ness.
Typically functions as an uncountable noun; when referring to specific episodes, 'bouts of' or 'attacks of' are common collocations.
