Disturbance in the recognition of objects following some brain injury that is not related to loss of vision, memory, language or mental retardation. The term was introduced in 1890 by Heinrich Lissauer in his paper published in Archiv für Psychiatrie und Nervenkrakheiten.  It was derived by clinical observation.
