ADD/ADHD are very much a spectrum. If someone is having trouble focusing for a few hours a day, even if it’s not literal days on end, I don’t think it’s crazy to investigate ADD/ADHD as the cause/name of the problem.
Agreed. Especially if slacking for days would quickly lead to negative consequences. ADHDs are often distracted until the very last moment when the failure becomes imminent -- and then work to avoid it.
Some times I go through periods where I do that repeatedly. Distracted and unproductive, to the point where it physically hurts, until there's no possible alternative but to work hard or fail.
