Meniere disease is best described as which type of disorder?

• A. Central nervous system disorder
• B. Inner ear disorder
• C. Autoimmune disorder
• D. Gastrointestinal disorder

Answer: (B)

Meniere disease is best described as an inner ear disorder because its hallmark problem lies in the labyrinth of the inner ear and its fluid balance. The condition causes episodes of vertigo, fluctuating sensorineural hearing loss, tinnitus, and a sense of ear fullness due to endolymphatic hydrops—excess fluid buildup in the inner ear that disrupts both balance and hearing. This peripheral, inner-ear origin distinguishes it from central nervous system disorders, which stem from brain or brainstem pathology and often show additional neurological findings, or from GI issues. Autoimmune involvement can be a considered contributing factor in some conditions, but the defining feature here is the inner ear fluid imbalance and vestibular dysfunction.
