title: A case of psychogenic dizziness mimicking vestibular epilepsy.
abstract: A 28-year-old patient presented with frequent episodes of clockwise whirling vertigo, with no ear symptoms or anxiety. He had a previous history of encephaloduroarteriosynangiosis from Moyamoya disease 3 years ago. We assumed that the ictus was a manifestation of vestibular epilepsy. Although the patient was monitored continuously with video and computerized electroencephalography equipment for 24 hours, his vertigo was not accompanied by electroencephalographic discharges. And thorough vestibular evaluation was normal. His symptom was alleviated by psychological support. Psychogenic dizziness may also manifest as recurrent whirling vertigo with unilateral directionality.
