You are examining a patient with a right parietal lesion and want to assess for hemiasomatognosia. Before revealing the answer, decide what you would look for.

Observe spontaneously, over the course of the examination, whether the patient ever mentions, looks at, or attends to the affected side of their body without being specifically prompted, since the affected limb or side may simply fail to be mentioned or attended to, rather than being actively described as foreign. When directly asked about the limb, listen for whether the patient produces any active claim about its ownership at all, since a genuinely active, elaborated denial — rather than simple non-registration — would point toward somatoparaphrenia instead. Check for other neurological signs on the same side, such as weakness or sensory loss, since hemiasomatognosia often occurs together with these, and examine for hemispatial neglect and anosognosia as well, given the three frequently coexist following the same right parietal lesion.
