Asomatognosia, is characterized by a loss of knowledge or recognition of half of the body or a limb, possibly due to paralysis or unilateral neglect.[1] Asomatognosic patients may, for example, mistake their arm for the doctor’s arm, however, can be shown their limb and this error is temporarily corrected.[2] [3].

The condition may take a number of forms[4]:

These disorders reflect parietal lobe dysfunction.
