Object reversals after parietal lobe infarction--a case report.

A case is described of a mixed manually dominant man with a right parietal infarction who demonstrated reversals in object manipulation. Although mirror reversals in parietal lobe dysfunction and right-left spatial reversal in conjunction with mirror writing have been reported previously, object and spatial reversal to this extent has not been reported. The theoretical implications of the absence of mirror writing here, in relation to side of brain lesion and handedness, are discussed.
