“…The complement of a crossed aphasia is a crossed “right hemisphere syndrome.” This is when the symptoms usually associated with a lesion in the right hemisphere in dextrals occur without aphasia in an individual with a lesion contralateral to the preferred hand. Although reports of crossed aphasia are fairly common, the crossed right hemisphere syndrome has been previously reported in a dextral only eight times (Han & Foo, 1983; Heilman, Coyle, Gonyea, & Geschwind, 1973; Junqué, Litvan, & Vendrell, 1986; Junqué, personal communciation, 1987; Kellar & Levick, 1985; Lincoln, personal communication, 1988; Podbros & DePiero, 1985; Taylor & Solomon, 1979).…”

A 71-year-old dextral man with a large left frontotemporal cerebrovascular accident (Cl'lt) had none of the expected impairments such as aphasia, buccofadal apraxia, alexia, agraphia, acalculia, left-right confusion, or finger agnosia. He did have symptoms usually found with right hemisphere damage, including contralateral hemineglect, anosognosia, a visual-spatial disability, dysprosody, impaired singing, poor judgment, impulsiveness, lethargy, and an indifference reaction. These findings suggest that he had crossed lateralization. They further suggest a possible affinity or commonality among the various usual functions of the right hemisphere. The patient had a moderate limb apraxia, suggesting that limb praxis follows handedness, not language lateralization. The prevalence and sex distribution of the syndrome are discussed. The implications of these findings for theories of cerebral lateralization are also discussed.
