“…In particular, the issue of whether functions migrate in clusters (Castro-Caldas et al 1987), or follow strict predetermined rules giving rise to predictable patterns of functional "situs inversus" (Kellar and Levick 1985) is still a matter of debate. A perusal of the literature on crossed aphasics seems to indicate that right and left hemisphere signs coexist in some patients (Haaland and Miranda 1982), and that several dissociations are possible, not necessarily mapping onto the predicted pattern of complete lateralisation. Indeed, cases of patients have been reported showing crossed limb or oral apraxia but not aphasia following a right hemisphere lesion (Alexander and Annett 1996; Marchetti and Della Sala 1997; Papagno and Della Sala 2000; Bizzozero et al 2000).…”

Crossed right hemisphere syndrome following left thalamic stroke

In most right-handed people, language and motor functions are more reliant on systems of the left hemisphere while several non-linguistic visuo-spatial and attentional processes depend more on the right hemisphere. The rare exceptions to these rules provide important clues as to what functions co-lateralise, and are thus crucial for models of cerebral specialization. Here we report on the case of a patient, who, after a lesion restricted to the left thalamic region, showed signs normally associated with right hemispheric injury including motor impersistence, visuo-spatial dysfunction and poor comprehension of facial expression. Language abilities were spared and no signs of apraxia were present, in spite of his right hand, foot and eye preference, a pattern normally associated with conventional cerebral dominance. In spite of his other right hemispheric signs, the patient showed no signs of hemi-spatial neglect. The patient's pattern of spared and impaired abilities is compared and contrasted with other rare cases of crossed right hemisphere syndrome.

“…1981, Henderson 1983, Basso et al 1985. Numerous case reports of non-fluent and fluent crossed aphasia describe multiple testings over time (Ettlinger et al 1955;Zangwilll979, Trojanowski, Green and Levine 1980, April and Han 1980, Carr et al 1981, Haaland and Miranda 1982, Habib, Joanette, Ali-Cherif and Pancet 1983, Hindson et al 1984, Basso et al 1985, Youngjohn 1986). However, little information is available regarding syndrome evolution during the acute phase of recovery, when changes in linguistic profile are typically most dramatic.…”

We describe the case of a 61-year-old right-handed male who developed global language deficits and muteness following a right hemisphere middle cerebral artery distribution infarct involving the frontal, inferior parietal and superior temporal lobes. Language was evaluated serially during the early stages of recovery in order to document the evolution of this syndrome with regard to the observed areas of linguistic change. Auditory comprehension and information content were the areas showing the greatest change during the early stages of recovery, while gains in fluency were limited. By 48 days post-onset, this patient's linguistic profile was behaviourally compatible with the Broca's aphasia seen with left hemisphere lesions.

“…To allow for comparison, fMRI data from 10 healthy controls participants (median age 52.5 years, 3 left-handed and 7 right-handed) who had carried out the same two tasks was also analysed for hemispheric lateralisation of the whole brain and temporal lobe, using the LI-tool (Wilke & Lidzba, 2007).

Across those studies, six main co-morbidities were found:…”

Cognitive impairments associated with crossed aphasia were investigated in a single case study and a review of the literature. A review of literature identifies 4 main cognitive co-morbidities that are significantly associated with crossed aphasia. We present a case of confirmed crossed aphasia with dyslexia and dysgraphia, in which the latter two cannot be fully explained by the current lesion and are probable developmental disorders (dyslexia/dysgraphia). Extensive longitudinal cognitive investigations and a series of advanced imaging techniques (structural and functional) were used to investigate the cognitive and neuroanatomical basis of crossed aphasia and associated impairments in this patient. Using the results from the literature review and the single case study, we suggest that developmental disorders can be an underlying cause of partial right lateralisation shift of language processes, thereby supporting the theory that developmental disorders can be an underlying cause of crossed aphasia.
