Which of the following is a symptom of Meniere's disease?

Meniere's disease is characterized primarily by recurrent episodes of vertigo, which is a sensation of spinning or dizziness. This condition affects the inner ear and is associated with fluctuating hearing loss, tinnitus, and a feeling of fullness or pressure in the ear. The hallmark symptom, recurrent vertigo episodes, is often debilitating and can last from minutes to several hours, significantly impacting a person's daily activities and quality of life.

While sudden severe hearing loss, constant ringing in the ears, and temporary auditory confusion may be related to various auditory or vestibular disorders, they do not specifically capture the classic symptoms of Meniere's disease as effectively as recurrent vertigo does. Sudden hearing loss can occur in other conditions such as noise-induced hearing loss or sudden sensorineural hearing loss, and though tinnitus is a common complaint, it often occurs continuously rather than recurrently in the context of Meniere's. Temporary auditory confusion may result from different factors and is not a defining characteristic of this particular disease. Therefore, the defining symptom that aligns most closely with Meniere’s disease is indeed recurrent episodes of vertigo.
