Aphasic victim as investigator.

The author (a classics professor) suffered a cerebrovascular accident, resulting in aphasia. In order to learn whether speech therapy helps aphasic patients to recover, the patient worked on Greek vocabulary and grammar and ignored Latin. (Both languages were equally well-known before the accident; skills in both languages had been totally lost afterward.) This case demonstrates the value of retraining an aphasic. After three years, testing demonstrated a professorial level of the Greek language, but Latin was essentially still missing.
