The Many Functions of Perseveration
Anyone who lives with a person with Fragile X is very familiar with this continuation of a repeated word or phrase. This repetition can be maddening when you are the recipient. At face value, perseveration has no redeeming features and simply serves as an irritant, but in the life of one with Fragile X syndrome (FXS), it can be a valuable asset. Perseverative verbiage often accompanies arousal and acts as a buffer to reduce the anxiety. The repetition can be comforting like a mantra or song.
