Why does vertigo occur with meniere syndrome?

Vertigo in Meniere's syndrome occurs due to abnormal fluid accumulation in the inner ear, specifically in the cochlea and vestibular system. This buildup, known as endolymphatic hydrops, disrupts the normal balance and hearing signals sent to the brain, leading to episodes of intense spinning sensations. The impairment of the vestibular system, which is responsible for maintaining balance, results in the characteristic vertigo associated with the condition. Additionally, fluctuations in pressure within the inner ear contribute to these vertiginous episodes.
