“…One of the most influential and widely held views on CAD of the last decades was advanced by Brown and coworkers in the 1970s (Brown and Wilson, 1973; Brown, 1976; Brown and Hécaen, 1976). In accord with the classical concept of acquired childhood aphasia and aphasia in sinistrals they defined CAD as prototypically non‐fluent and often transient regardless of the lesion site (Mariën et al ., 2001b,c). Many subsequent studies added evidence to this view supporting the concept of more diffuse language representation as the consequence of a disrupted lateralization process (e.g.…”

“…Nine of the 19 cases were excluded for the following reasons: non‐vascular aetiology (five cases), familial sinistrality (one case), additional vascular damage to the language areas of the left hemisphere (two cases), incomplete record lacking information on familial left‐handedness, early brain damage and developmental milestones (one case). One case represents CAD in acquired childhood aphasia and was extensively reported previously (Mariën et al ., 2001a; Mariën et al ., 2001b,c). All cases withheld for the present study are adults.…”

A substantial body of the aphasia literature has been devoted to the topic of crossed aphasia in dextrals (CAD) over the past century but still no theory exists that explains the anomalous organization of neurocognitive functions in this population. However, if strict selection criteria are applied only some cases of vascular CAD are reported in which the correlation between neurocognitive disturbances and the locus of the brain lesion is studied. This study describes nine new cases of vascular CAD who underwent in-depth neurolinguistic and neuropsychological investigations. Our analysis shows the semiological variability of CAD phenomena and the many faces of the lesion-behaviour relationships of this exceptional neurobiological condition.

“…Overlapping findings have been obtained (Lurito and Dzemidzic, 2001). Marien et al (2001) also concluded that lateralized cerebral dominance for language represents an innate, predetermined neurobiological system, on the basis of a very rare occurrence of crossed aphasia in dextral children. The association between handedness and language laterality index, and between family history of handedness and language laterality index may indicate a common genetic factor underlying the inheritance of handedness and language lateralization.…”

The study is aimed at identifying hemispheric language dominance in both the right-handed and left-handed participants. Eighteen right-handed and 18 left-handed young volunteers were invited to listen for 80 times to a 720 ms duration Italian word. Signals from 16 electrodes were averaged and displayed both as traces and maps. When the word was delivered to the participant, a positive component at 340 ms was recorded, following the N100-P200 complex. The potential was significantly lateralized to the left hemisphere in 50% of the right-handers. The left-handed group was less homogeneous. Six out of 18 participants (33%) had a right lateralization, six participants (33%) had the positive potential shifted to the left hemisphere. Finally, the remaining participants had a bilateral representation. The maps show that there are no two participants alike, independently of either sex or handedness. A 300 Hz tone of the same duration failed to evoke the P340. Results indicate the utility of event-related potentials in studying the language processing. The possibility to identify cortical localization permits a better prognosis of acquired aphasia. The method is relatively cheap and noninvasive. Application is suggested in those participants who are at risk of stroke or in patients to be submitted to a neurosurgical intervention nearby possible language areas.

“…Bereits 1987 wurde von Schweiger die Hypothese aufgestellt, dass metabolische Veränderungen im Hirnstoffwechsel der rechten Hemisphäre einen Einfluss auf die morphologisch intakte linke Hemisphäre haben könnten [53], ohne dass dort eine morphologisch fassbare Läsion nachweisbar ist. Mögliche inhibitorische Prozesse der rechten auf die linke Hemisphäre waren auch der Grund, warum einige Autoren Patienten mit rechtsseitigen, infiltrativ oder raumfordernd wachsenden Hirntumoren aus ihren Datenerhebungen ausschlossen [54]. Schweiger et al konnten in einer PET-Untersuchung an einem Hirninfarktpatienten keinen Beleg für diese Hypothese finden [53].…”

Crossed aphasia (CA) is a rare acquired language disorder caused by a right-sided brain lesion in dextrals. Based on a case report, relevant aspects for the diagnosis of CA and differential diagnoses will be outlined. Relevant hypotheses concerning etiology, epidemiology, phenomenology and pathophysiology will be discussed with reference to the literature. The phenomenon of CA has contributed for decades to the development of hypotheses concerning lateralization of cognitive abilities.
