Acquired aphasia with convulsive disorder: course and prognosis

Acquired aphasia with convulsive disorder is an unusual condition in childhood, characterized by loss of language function associated with a paroxysmal electroencephalogram. To determine the course and outcome of this disorder, we evaluated nine patients 10 to 28 years after the onset of aphasia. Four patients had recovered fully, one had mild language dysfunction, and four had moderate language disability. Four of the five patients with the best outcome had decreased visuoperceptive function as measured by the Revised Benton Visual Retention Test (RBVRT), whereas the three tested patients with moderate language dysfunction had normal RBVRT scores.
