The following is true of congenital prosopagnosia:

• it is accompanied by severe neurological impairments and intellectual deficits

• it is characterized by severe visual deficits and near-blindness

• it is present from early childhood, suggesting familial predisposition

• it is usually caused by a sudden lesion, such as a stroke
