talk and die syndrome

(名詞) 談話中猝死症:腦部創傷 (traumatic brain injury) 的人在受傷當時並無大礙,身體也不覺得有重大不適,照樣談笑風生,但一、兩天後即陷入嚴重昏迷並宣告不治的症狀。

Doctors have suggested that Richardson suffered from something called “talk and die” syndrome, in which bleeding that occurs between the skull and brain stem is delayed. Patients seem fine after the trauma and may think there is nothing wrong. However, as the condition in their brain deteriorates they, too, deteriorate and their chances for survival decrease.
