Vertigo is a sensation of spinning and loss of balance, while dizziness is an umbrella term for various sensations, such as lightheadedness, vertigo, confusion, and imbalance. The usage of these terms are as subjective as the sensations themselves. Thus, it takes a very well-trained physician to be able to pinpoint the underlying cause from the myriad of related conditions. Vertigo, dizziness, balance disturbances, and lightheadedness that can lead to syncope can be caused by disorders of the inner ear (e.g., labyrinthitis, vestibular neuritis), disorders of the cerebellum (e.g., infections, ischemia, hemorrhage), and cardiovascular conditions (e.g., heart failure, arrhythmia), among many others. For optimal comprehension, the student must be familiarized with the anatomy and physiology of the cerebrovascular system, central nervous system, and vestibular system.
