Children's acquired aphasia screening test.

Diagnosis in acquired childhood aphasia (ACA) is a multi-stage process. After the medical condition has stabilised, the diagnostic evaluation requires careful assessment to establish a profile in the differential diagnosis of listening, understanding speaking, and gesture. Children with ACA were traditionally assessed on adapted batteries often used for adults. The Children's Acquired Aphasia Screening Test (CAAST) was specifically designed to evaluate linguistic and non-linguistic function in brain-damaged children aged between 3 and 7 years.
