Dizziness and Nausea Feeling During Pattern Reversal Checkerboard Visual Evoked Potential Recording in A Multiple Sclerosis Patient

Dizziness and nausea are among the symptoms of multiple sclerosis (MS). The present manuscript reports a case suspected of MS who experienced severe dizziness and nausea while recording pattern reversal checkerboard (PRC) visual evoked potential (VEP), whereas she felt comfortable during the flash type of VEP (FVEP). Therefore, we suggest recording FVEP in patients with any problem produced due to PRC VEP.
