Mirror Agnosia

Mirror Agnosia

Mirror agnosia, or the "looking glass syndrome", is a phenomenon observed in patients with left hemispatial neglect as a result of right parietal lobe lesions. There is inability to point to objects seen in a mirror, with repeated reaching "into" the mirror even when the actual location of the target is shown. In a milder form, known as "mirror ataxia", patients reach in the direction of the object but with increased errors of reach and grasp, suggesting that visual information is not adequately transformed into a body-centered frame of reference.
