The origin of the word vertigo is in the Latin vertere, meaning to turn. Conversely, the word giddy is believed to be derived from the Old English word gidig, meaning insane or, literally, possessed by a god.
Vertigo is a symptom. Its not the same as dizziness or disequilibrium.
Vertigo is a sensation of motion (usually whirling) either of the body or the environment, caused by asymmetric dysfunction of the vestibular system.
However it is described; it doesn’t compare to how vertigo feels and how fearful you become. Vertigo is terrifying because it is unpredictable and dislocates your sense of space.
