ABSTRACT
<p><b>OBJECTIVE</b>To investigate the visual evoked potentials in adults with migrainous vertigo (MV).</p><p><b>METHODS</b>Totally 113 patients with MV were enrolled from vertigo clinic. Patients received necessary laboratory examinations as well as pattern visual evoked potential (PVEP) testing.</p><p><b>RESULTS</b>Definite MV accounted for 46.9% (53/113) and probable MV accounted for 53.1% (60/113). Among 74 patients who received PVEP, the results were normal in 35 patients (47.3%) and abnormal in 39 patients (52.7%). The abnormal manifestations included lowered N75-P100 amplitude, elongated latency of P100, and lowered N75-P100 amplitude combined with delayed latency of P100. Seven patients with MV had unilateral lowered N75-P100 amplitude and 4 had bilateral abnormal amplitude. Nine patients had unilateral delayed latency of P100 and 11 had bilateral abnormal latency. Four patients had unilateral and 4 had bilateral abnormal N75-P100 amplitude and latency of P100.</p><p><b>CONCLUSIONS</b>MV patients usually have abnormal PVEP. PVEP may become a useful electrophysiological test in the diagnosis of MV.</p>
