Controversy
Some researchers have suggested that DES is mislabelled as a syndrome because it is possible for the symptoms to exist on their own. Also, there is not a distinct pattern of damage that leads to the syndrome. Not all patients with frontal lobe damage have DES and some patients with no damage at all to the frontal lobe exhibit the necessary pattern of symptoms. This has led researches to investigate the possibility that executive functioning is broken down into multiple processes that are spread throughout the frontal lobe. Further disagreement comes from the syndrome being based on Baddeley and Hitch's model of working memory and the central executive, which is a hypothetical construct.
The vagueness of some aspects of the syndrome has led researchers to test for it in a non-clinical sample. The results show that some dysexecutive behaviours are part of everyday life, and the symptoms exist to varying degrees in everyone. For example, absent-mindedness and lapses in attention are common everyday occurrences for most people. However, for the majority of the population such inattentiveness is manageable, whereas patients with DES experience it to such a degree that daily tasks become difficult.

Famous quotes containing the word controversy:
“Ours was a highly activist administration, with a lot of controversy involved ... but I’m not sure that it would be inconsistent with my own political nature to do it differently if I had it to do all over again.”
—Jimmy Carter (James Earl Carter, Jr.)
“And therefore, as when there is a controversy in an account, the parties must by their own accord, set up for right Reason, the Reason of some Arbitrator, or Judge, to whose sentence, they will both stand, or their controversy must either come to blows, or be undecided, for want of a right Reason constituted by Nature; so is it also in all debates of what kind soever.”
—Thomas Hobbes (1579–1688)
