Man speaks fluent Spanish after surgery due to rare foreign language syndrome

An American man who knew minimal Spanish began speaking the language fluently after undergoing surgery. This rare phenomenon has only been documented in about 100 individuals worldwide since 1907. The man, Steven Chase, experienced this after knee surgery at age 19. He would speak full sentences in Spanish for about 20 minutes before reverting to English, despite only knowing basic phrases and counting to ten prior to the operation. Chase has since been diagnosed with Foreign Language Syndrome, a condition that can be triggered by factors including brain trauma or anesthesia. He has experienced this fluent Spanish speech after multiple surgeries over the past decade.
