could executive dysfunction be like perseverance and not being able to tear yourself away from something to do something else?

Yes, this is hyperfocus and inertia. Inertia is a type of executive dysfunction where you are stuck doing whatever you’re doing until something happens to jolt you out of it so you can do something different. It gets its name from Newton’s first law of physics, which states that an object at rest will remain at rest, or an object moving in a straight line will continue in that straight line unless it is acted upon by an external force. (Source) Hyperfocus is the part where you’re focused on something and not really aware of anything else.
