Dizziness is a condition that occurs when a patient feels motion even though they and their surroundings are not moving. Much like headaches, many people encounter dizziness in their daily lives. Dizziness includes normal physiological reactions to external stimuli such as going up a high building and motion-sickness, as well as those caused by life-threatening illnesses such as brain tumors and strokes. I do see a fair number of patients who visit the clinic due to dizziness, but it is not a straight-forward procedure to diagnose the root causes because dizziness is a common symptom for various illnesses.
