anatomical syndromes

This is a case of Anton Syndrome or cortical blindness. It is most commonly caused by ischemic infarcts involving bilateral posterior cerebral artery vascular territories. Patients cannot see but often deny the presence of blindness, even with clear evidence. This is treated with visual training and rehabilitation. A lesion to the inferior lip of the occipital lobe can present as colorblindness and is known as achromatopsia. Bilateral parietal-occipital lobe injury can lead to Balint’s syndrome. This typically presents as a triad of optic ataxia, oculomotor apraxia, and simultagnosia (inability to focus on multiple objects). Gerstmann’s syndrome presents as agraphia, acalculia, finger agnosia, and left/right confusion.
