WESTBOROUGH, MA July 23, 2016 Perseveration results from a change in cognitive status often seen in athletes with concussion. It is most often manifest when an athlete says or does the same thing over and over without realizing it. In some cases the athlete will make an effort to cover for themselves expecting that no one will notice that anything is amiss. Not so fast. The last one to notice that anything is wrong is the athlete with a concussed brain. Everyone else notices but not him. Recently the NFL has made it mandatory for a teammate who suspects that a teammate has sustained a concussion must say something to the coaches or trainer.
In patients with concussion the confusion evaporates quickly generally within minutes to hours. The video shown here depicts a case of perseveration that is more severe. It is an older patient who sustained a fall and is quite altered. The video illustrates a case of altered mental status resulting in perseverative drawing in circles. In general, patients who are older have a slower recovery than younger ones. This video shows the stark lack of self-monitoring as the patient attempts to construct a simple clock.
