Vertigo encompasses a broader concept, including conditions like benign paroxysmal positional vertigo (BPPV). Any disease that can cause patients to experience symptoms such as dizziness, spinning sensations, nausea, and vomiting, can be referred to as vertigo. BPPV is simply one common cause of vertigo. It primarily results from otoconia forming in the vestibule's semicircular canals or the utricle and saccule. These otoconia shift with head movements, disrupting the inner ear's lymph fluid, leading to transient episodes of vertigo closely related to body position changes. These episodes, lasting several seconds, can be completely alleviated and are considered a type of vertigo. Additionally, vertigo includes diseases like vestibular neuronitis and Ménière's disease. Therefore, the concept of vertigo is quite broad, and it is crucial to accurately diagnose the cause of vertigo in clinical practice to provide targeted treatment.
