Our observation in two patients with recurrent vertigo will be presented in this paper on cholesterol, β-lipoprotein, triglyceride and non-esterified fatty acid (NEFA) of the blood during each attack in the same patient. Our particular interest was the level of NEFA.<BR>Case I.H.T. This 37-year old man was first seen on May 26, 1977. He complained that vertigo awaked him from his sleep. On the fourth attack he suffered from hearing impairment in the right ear. From otoneurological examination, a diagnosis of Meniere's disease associated with hyperlipoproteinemia was made.<BR>Case II.H.N. This 38-year old man was first seen on July 1, 1975. He complained of vertigo and nausea. The associated nystagmus was not labyrinthine but central, and the vertigo was attributed to disturbance of brain circulation associated with hyperlipoproteinemia.<BR>NEFA showed high levels 0.73, 1.40, 1.44 and 0.93mEq/l on the first patient and 1.12, 1.21, 0.69 and 1.16mEq/l in the second. In the absence of of vertigo, NEFA returned respectively to the normal range and cholesterol and β-lipoprotein showed no change. Triglyceride decreased in the first patient.<BR>To clarify the relationship between vertigo and the autonomic nervous system, an equilibrium test with loading of adrenaline was given. After the load, equilibrium function remained unchanged, despite an increase in NEFA.<BR>These results indicate that the increase of NEFA was not an immediate cause of attacks of vertigo. Therefore, we considered that the occurrence of vertiginous attacks was probably due to production of acetone bodies resulting from imperfect combustion related to metabolism of NEFA.
