Vertigo. Pars secunda

After the excursus into the world of vertigo in the pars prima in contact with the 17^th and ¹⁸th centuries, the figure of P. Menière (1799-1862), the 19th-century scholar and otorhinologist. His life and professional development contrast with the scope of his intuition on vertigo; this is borne out by his professional and scientific leaning towards ear pathology dictated, in older age; by events and necessity. His observations altered the deep-rooted conviction that a cerebral lesion was the underlying cause of vertigo, instead shifting the etiopathogenetic vision towards lesions of the inner ear. He opened the way to the future labyrinthology, leading to the differentiation between central and peripheral forms of vertigo.
