Presentation  
    The patient presents with a complaint of dizziness, which may be abrupt or gradual in onset. The symptoms may be reported in many different ways, such as lightheadedness, disequilibrium, room-spinning vertigo, imbalance, wooziness, or incoordination. The patient may have persistent symptoms associated with severely debilitating nausea and hence be reluctant to engage in an examination or provocative maneuvers. However, differentiating benign from dangerous causes of dizziness can be challenging, and a careful history and physical examination are key to accurate diagnosis and management.
