Evaluation and outcome of aphasia in patients with severe closed head trauma

In this study long-term observation of 12 patients with aphasia secondary to severe closed head trauma took place. The most frequent symptoms were amnestic aphasia and verbal paraphasia. Only one patient with a constant slow wave EEG focus in the dominant hemisphere had severe receptive symptoms. In all other patients the aphasia recovered rather well, though not totally, but the presence and degree of concomitant neuropsychological disorders were most important for the final outcome.
