Lermoyez syndrome is a variant of Meniere's disease characterized by:

• A Sudden drop attacks without loss of consciousness (Tumarkin otolithic crisis)
• B Bilateral simultaneous Meniere's disease from the onset
• C Vertiginous attack PRECEDED by hearing improvement rather than hearing deterioration ✓
• D Vestibular symptoms alone without any auditory component (vestibular Meniere's)

Explanation

Lermoyez syndrome is a rare variant of Meniere's disease in which, counterintuitively, the patient's hearing IMPROVES just before or during a vertiginous attack, then returns to the baseline low-frequency SNHL after the attack resolves. The proposed mechanism is sudden decompression of the endolymphatic hydrops during the attack, temporarily restoring normal endolymph pressure and improving cochlear function. Tumarkin otolithic crisis describes sudden drop attacks (vestibular drop attacks) in Meniere's without loss of consciousness.
