Introduction: Episodic vertigo frequently occurs in patients suffering from ischemia in the distribution of the vertebrobasilar (VB) circulation.

Methods: Thirty-five patients, eighteen males and seventeen females, aged from twenty-seven to eighty years old were included in this study. All these patients had vestibular symptoms not attributed to known peripheral vestibular diseases, and vascular cerebral abnormalities on the imaging studies but without neurologic symptoms.

Results: Spontaneous nystagmus was evidenced in 16 patients. Positional nystagmus was direction-fixed in 4 cases and direction-changing in 5 cases. The positioning nystagmus was geotropic in 2 cases (in one without latency) and ageotropic in one patient. In bithermal caloric test, directional preponderance was revealed in most of cases. The auditory brainstem responses showed prolongation of latency III-V in 10 cases, of I-V in 8 cases, and of I-III in 3 cases. The V amplitude was diminished or missed in 4 patients.

Conclusion: Central findings were found in 60% of cases, peripheral in 8.5% of patients and mixed in 31.4% of cases. It seems that that there is an initial circulatory cerebral deficit within the VB arterial system which at a certain time may lead to disturbances in blood supply of the labyrinth and producing cochleovestibular dysfunction. Therefore, a neurologic consultation is always mandatory in order to assure the safety outcome of these patients and possibly anticipate any further clinical aggravation.
