  1. There were statistically highly significant differences between patient and control groups regarding executive function with the patient group performed poor regarding trial administered (conceptualization) and categories completed (abstract ability) (p < 0.001) and also had a statistically significant higher percentage of perseverative errors (cognitive flexibility) (p < 0.05)
