Definition

Crossed aphasia is an acquired language impairment following a lesion in the right hemisphere in a right-handed individual.

Current Knowledge

The term “crossed aphasia” (CA) was coined by Byrom Bramwell (1899) to indicate an aphasia caused by a cerebral lesion ipsilateral to the dominant hand regardless of handedness. Currently, CA only refers to right-handed individuals. The frequency of CA among stroke survivors is rare (1–3%).

Although some earlier authors considered CA to be the consequence of a weaker language lateralization, it appears that individuals with CA have language as strongly lateralized as those with left-hemisphere aphasia (LHA), mainly because both populations show a similar prognosis.

CA can be mirror image or anomalous (Alexander et al. 1989). Mirror-image CA denotes the expected correspondence between symptomatology and lesion location within the language-dominant hemisphere, whereas anomalousCA implies the presence of unexpected language symptoms...
