Aphasia after stroke: a detailed study of recovery in the first 3 months.

This is a prospective study of recovery of aphasia in 19 stroke patients selected from 117 consecutive hospital admissions by virtue of having significant aphasia and surviving 13 weeks. Aphasia was measured using the Frenchay Aphasia Screening Test (FAST) at frequent intervals from early after stroke. A wide variation in speed and extent of recovery was seen, particularly when compared with mean scores. Patients who made the most recovery had started to improve by 40 days post-stroke. An aphasic patient's FAST score at 13 weeks post-stroke could be predicted from his first score (within 2 weeks).
