A 48-year-old man who had olfactory-induced attacks of vertigo with tinnitus and impaired hearing for two years was diagnosed as syphilitic hydrops and underwent bilateral Portman's operation at intervals of three months. The vertiginous attacks disappeared but the olfactory induced dizziness continued. We noted that the dizziness could be induced when he inhaled petroleum derivatives and garlic odors. Immediately after intravenous injection of 10mg of alithiamine, nystagmus was recorded on ENG and such was accompanied with salivation. Thus, it would appear that neural mechanisms are directly involved in olfactory induced nystagmus.
