Abstract
Natural recovery of aphasia was investigated in thirty stroke patients (11 cerebral hemorrhage, 14 cerebral infarction, 5 subarachnoid hemorrhage) who had never been taken speech therapy. The SLTA was applied to all the subjects at the first month and three months interval from the onset. At the same time, the severity of their comprehension, oral speech and writing was evaluated with SLTA three dimensional scale. Comprehension score showed some improvements for first 3 months in amnestic type, in other types it improved after 6 months. Oral speech score was showed some improvements in amnestic type for 3 months, and in expressive and receptive type it showed some improvements after 6 months. Oral speech score showed no improvement in expressive-receptive type. Writing score showed some improvements in all types except for expressive-receptive type. Expressive-receptive type showed no improvement.
These results suggest that severe aphasia can not improve without speech therapy.
