Aphasics examined in army hospitals showed no reliable correlation between type of language dysfunction and the site of injury. These patients showed no consistent relation between the extent of brain injury and their capacity to relearn. Loss of capacity to abstract, observed in civilian aphasics, was by no means a general characteristic of the behavior of most aphasic patients in the Army. An avg. or higher pre-morbid intelligence was more frequently associated with aphasia and with the maintenance of aphasic disturbances than was below avg. intelligence. Pre-morbid personality traits are highly important factors. In regard to the site of brain injury, there was only one consistent finding: When aphasic disturbances continued to be present 3 or 4 mos. after the incidence of trauma, it was noticed that the injured area always involved part of the contra-lateral brain hemisphere. Except in cases where the amt. of brain injury was extremely great and involved both brain hemispheres, the extent of brain injury seemed to have little bearing on the patient''s progress and improvement. One patient had suffered approx. 25% brain loss in the left occipital and parietal areas. Despite this loss, he progressed from being an almost global aphasic to a point where he could speak with a fair degree of fluency, could write and copy from dictation and could read simple blueprints. In contrast, another patient with comparatively little known brain injury in the left temporal area had persistent and severe difficulties after more than a yr. of training. In 30 aphasic patients, only 2 showed any significant loss in the ability to Of 69 aphasic patients at 2 Army Neuro-surgical Centers, the General Classification scores showed that 55 patients were avg. or better in intelligence. Data on educational achievement tend to support this observation. A study of 64 patients showed that the majority was in the higher educational group. Subjectively, the author states that those aphasic patients who showed severe expressive disturbances were for the most part withdrawn individuals prior to head injury. Red Cross social service histories tended to support this belief. The observations, the author states, are tentative.
