Vestibular syncope is a rare condition in which vertigo may cause syncopal attacks; however, the term has been associated with confusion because it has been ascribed to completely different vestibular and neurological conditions, from dizziness to Menière disease (MD), to the neurovegetative symptoms in benign paroxysmal positional vertigo (BPPV) and central vertebrobasilar hyperfusion. A 75-year-old woman with vasodepressive vasovagal syncope, confirmed by a tilt test with trinitrine administration, was referred for an audiological and vestibular assessment showing an acute unilateral peripheral vestibular deficit on the right side. The diagnosis is peripheral acute vestibular deficits. Interventions and outcomes are vestibular treatment and rehabilitation. The patient's vasovagal symptoms immediately improved and were completely resolved. Peripheral vestibular deficits might also trigger syncopal episodes and must be considered and studied by a complete audiological and vestibular evaluation. By restoring the peripheral vestibular function of the right labyrinth after vestibular treatment, a complete long-term resolution of multiple vasovagal syncopal episodes was observed together with normalization of the tilt test.
