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]:
- Unilateral asomatognosia - unawareness or denial of hemiplegia, most frequently on the left following right hemisphere lesions
- Bilateral types including:
- Autotopagnosia
- Gerstmann syndrome,
- Asymbolia for pain - an abscence of a response to pain stimulation
- Phantom limb syndrome
These disorders reflect parietal lobe dysfunction.
