Hereditary vestibulo-cochlear dysfunction and vascular disorders

A family is described with a progressive autosomal dominant vestibulocochlear dysfunction resulting in a Dandy syndrome, head movement dependent oscillopsia and hearing loss. The history was negative for other neurological or otological diseases (including infectious diseases) or use of neuro-ototoxic drugs, except for a high incidence of vascular disorders (hypertension, stroke, and heart infarction).
