What Causes Benign Paroxysmal Positional Vertigo?
Many people experience their first attack of benign paroxysmal positional vertigo when waking up in the morning and are quite frightened by the intensity of the symptoms. The actual vertigo is usually of short duration (less than a minute) but the intensity of the sensation is so strong that the patient often reports experiencing a much longer attack. Most cases of benign paroxysmal positional vertigo resolve within a few weeks or months without any treatment. Often people can identify the exact movement that causes their vertigo and they tend to avoid making these movements in order to avoid the onset of symptoms. The exact physiological mechanism responsible for benign paroxysmal positional vertigo is a subject of debate.
