Persistent Continuous Dizziness: Pathophysiology and Treatment

Persistent blurred vision and oscillopsia have a negative impact on quality of life, and the burden of these symptoms is more severe than that of rotationally vertiginous attack. We doctors should take patients' pain as our own and treat them accordingly. However, because these cases are rather rare in daily clinical experience, in reality we tend to treat these patients as neurosis cases and send the patients home without providing adequate care. We conducted a retrospective study involving] 82 recently treated clinical cases and found that "jumbling of objects," which is thought to be caused by bilateral peripheral vestibular lesions, was more often observed in patients with central vestibular lesions. We named this the pseudo-Dandy phenomenon. In this study, we discuss the pathophysiology and treatment of this pseudo-Dandy phenomenon.
