Dizziness is a term used to describe a range of sensations, such as feeling faint, woozy, weak or wobbly.
Dizziness can be classified into four main types: vertigo, disequilibrium, presyncope, or lightheadedness. Although appropriate history and physical examination usually leads to a diagnosis, the final cause of dizziness is not identified in up to one in five patients
