Anton–Babinski syndrome is mostly seen following a stroke or head injury. Those who have it become completely blind as a result of the injury, but often are quite adamant in the face of clear evidence of their blindness that they are capable of seeing. They employ confabulation to fill in the missing sensory input. Following the accident, it may take days or weeks for doctors and family members of the victim to realize that the patient is blind. The patient will collide with pieces of furniture, fall over objects, may try to walk through a wall or through a closed door or talk to people who aren’t there at all.
