Executive dysfunction is common in survivors of #Covid_19 and #PICS but how is it expressed? Let's unpack the expressions of this condition in a 🧵. @CIBScenter @WesElyMD 1 of 5 
The 'sine qua non' of executive functioning is planning. Often measured using the WCST or the Tower Test. Deficts reflect an inability to formulate strategies, to take efficient routes, to anticipate needs in advance, to tackle problems systematically. @CIBScenter
Another key component is called "set shifting" - assessed on brief cognitive tests like the Trails B Test - it involves the ability to transition rapidly from one type of task to another, and then back again. Set shifting deficits interfere at home and work. @CIBScenter
Still another component? Inhibition control - assessed on tests like the Hayling Test. Deficits in inhibition result in an inability to suppress or respond to thoughts, behaviors, and responses. Problems with inhibition can create havoc for social functioning. @CIBScenter
Yet another component? Working memory - really an "executive" ability at heart and assessed by tasks like reciting digits backwards. Impaired working memory makes it hard - to list one example - to remember a phone number someone just gave you while you dial it.

@CIBScenter
One more? Fluency - the ability to generate responses from the "storehouse" of your memory, using an efficient strategy (list letters that start with "F", list fruits, vegetable, or animals). Impaired fluency prevents people from generating responses. @CIBScenter
Volumes have been written about executive dysfunction. This is the thinnest summary but may help someone. If you have executive deficits, help and answers are available. @CIBScenter
