用法筆記
Uncountable and almost always used without an article: doctors write 'the patient has asterixis', never 'an asterixis'. It most often appears as the object of 'show', 'have', or 'develop', or as the subject of 'be present / absent'. Belongs to clinical writing; in everyday speech the plain name 'flapping tremor' is used instead.
