Anton-Babinski Syndrome

Anton-Babinski syndrome, also called Anton syndrome or visual anosognosia, is a rare condition, caused by damage to the occipital lobe, in which a person who has become cortically blind firmly denies being blind and insists they can still see despite clear evidence to the contrary. Rather than acknowledging the loss of sight, affected people confabulate, describing people or objects that are not actually there, and their blindness typically only becomes obvious when they bump into furniture or stumble over objects while speaking and acting as though their vision were normal. Named after the neurologist Gabriel Anton, the condition usually follows a stroke or head injury and remains extremely rare, with only a small number of cases documented in the medical literature.
