Etymology
The term "executive dysfunction" is derived from the word "executive," which refers to the ability to execute or carry out tasks, and "dysfunction," which means abnormal or impaired functioning. The term is used to describe a set of cognitive abilities that are controlled by the brain's frontal lobes.
