Balint's syndrome. Report of four cases with watershed parieto-occipital lesions from vertebrobasilar ischemia or systemic hypotension.
Four patients with Balint's syndrome secondary to bilateral parieto-occipital ischemic lesions are presented. The pathogenesis of these lesions corresponded to either occlusive arterial disease in the vertebro-basilar system or the effects of systemic hypotension. The clinical features of this syndrome are discussed, along with the pathophysiology and time course of the condition, with particular emphasis on etiological factors, which make of this condition a distinct clinico-pathological syndrome.
