Anomalous Cerebral Language Organization: Acquired Crossed Aphasia in a Dextral Child

Acquired Crossed Aphasia in Dextral Children Revisited

“…The cases reported by Burd et al (1990) and Mariën et al (2001) fulfilled the criteria for reliable CAD. Burd et al (1990) assessed handedness in a 4-year-old boy who had become aphasic after an infarct in the right middle cerebral artery territory by parental report using the Edinburgh Inventory (Oldfield, 1971).…”

“…The patient described by Burd et al (1990) showed severe anomic deficits and prosodic disturbances after an 8-day period of mutism. The restricted verbal output of the patient described by Mariën et al (2001) was contaminated by phonematic paraphasias and dysarthria. The cardinal feature of the dysarthria was a hypertonic, effortful articulation.…”

“…Twelve years later, Assal (1987) reinvestigated this patient. The other patients were reported by Martins, Ferro, and Trindale (1987); Burd, Gascon, Swenson, and Hankey (1990); Martins, Antunes, Castro-Caldas, and Antunes (1995);and Mariën, Engelborghs, Paquier, and De Deyn (2001). Schematic case presentations such as the one in the sample of Hécaen (1976) and Woods and Teuber (1978) (case 18) were considered too concisely documented to allow any further analysis and were not withheld in the present review.…”

“…On the basis of these considerations it might be argued that only patients with developmental disturbances affecting language to the degree of a developmental dysphasia should be treated as a distinct group. Mariën et al (2001) reported a 13-year-old strongly right-handed girl who developed aphasic symptoms following a right cortico-subcortical temporo-parietal hemorrhage. Repeated CT and MRI studies of the brain confirmed the structural integrity of the left hemisphere.…”

“…Only the reliable CAD cases reported by Burd et al (1990) and Mariën et al (2001) constituted a sufficiently reliable source of information to allow comparison between cases and theoretical deductions. Though this small number of patients does not allow general conclusions, potentially relevant tendencies might nevertheless already be suggested with respect to aphasic semiology and lesion-behavior relationships.…”
