Abstract

Benign paroxysmal positional vertigo is most common cause of recurrent positional vertigo. However, recurrent positional vertigo also could result from pathology of central nervous system. The aim of this article is to review the clinical characteristics for recurrent positionally induced vertigo. Various diagnostic and therapeutic procedure are discussed for this condition, which could provide useful clueDisequilibrium is a sensation of impending fall or of the need to obtain external assistance for proper locomotion. Imbalance with vertigo is usually resulted from acute asymmetry of vestibular tone. However, imbalance without vertigo implicates situations such as slow loss of vestibular function, cerebellar lesion, proprioceptive dysfunction, and lesion involving motor centers of the basal ganglia and frontal lobe. Therefore, it is important that we try to take a delicate history and thorough neurologic examination focused on establishing the underlying diseases and the central mechanisms that mediate responses to these sensory systems.
