The association of bilateral vestibulopathy with cerebellar ataxia was first reported in 1991 and delineated as a distinct syndrome with a characteristic and measurable clinical sign-an absent visually enhanced vestibulo-ocular reflex-in 2004. We reviewed 27 patients with this syndrome and show that a non-length-dependent sensory deficit with absent sensory nerve action potentials is an integral component of this syndrome, which we now call cerebellar ataxia with neuropathy and bilateral vestibular areflexia syndrome (CANVAS).
