Synopsis by Sarah Ing
What must it be like to see yourself in the mirror, and not recognize yourself looking back? Nova investigates this frustrating condition called visual agnosia. Defined as the inability to identify familiar objects and faces, the perception difficulty is a scientific wonder. Alzheimer's patients and victims of strokes sometimes develop visual agnosia. It was first popularized by neurologist Oliver Sacks, author of The Man Who Mistook His Wife for a Hat. Now, doctors understand the syndrome better even though it retains its puzzling characteristics. Nova documents the real-life cases of two people living with visual agnosia.
