Global aphasia without hemiparesis following prerolandic infarction.

Acute global aphasia without hemiparesis (GAWH) is said to result from the association of 2 separate lesions in the anterior and posterior left hemisphere language areas. We present 2 unusual cases of GAWH whose CTs revealed only a single lesion of the posterior part of F2 and F3. There was good recovery of verbal communicative abilities. Functional disconnection of posterior language areas seems responsible for this syndrome in such cases.
