This study takes news reports in Taiwan from 1951 to 2010 as the sample and examines how these news reports as public discourse have constructed dementia's Chinese names and stigma. At first, "癡呆" was only a common expression, but then it developed into an illness name and even a curse word. Moreover, with special writing rules specific for journalism, these news reports reinforced dementia's negative stereotypes as a shameful and disgraceful illness. This study hopes to help people be more introspective toward the stigma of illnesses and diseases in society.
