We report two patients with characteristic behavioral features, which were denial of blindness, indifference to self and environment, severe memory impairment, and confabulation. It seems that transitory functional depression of the right parietal cortex caused by de-afferentation from the occipital lobe is likely to produce unawareness of visual failure. Dysfunction in both temporal lobes secondary to insufficiency of the posterior cerebral arteries may be responsible for memory impairment accompanied with confabulation. It suggest functional depression in parietal and temporal lobes, not occipital lesion perse, is necessary to produce Anton's syndrome in patients with bilateral occipital lesions. To our knowledge, this is the first report on the Anton's syndrome in Korea. But functional brain imaging such as brain SPECT or PET is required to prove my assumptive mechanisms.
