Horner and Cazals (2005) assessed cortisol and ACTH in patients with Meniere’s disease and vestibular schwannoma and compared them with levels in patients with hemifacial spasm (as controls), and reported a strong positive correlation between ACTH and cortisol in patients with vestibular schwannoma and Meniere’s disease, but no such correlation in patients with hemifacial spasm. This evidence concerns the gene POMC and Meniere disease.
