The problem is that there are many other mental disorders that have a profound effect on executive function as well
I was watching a video from dr berkely and he said its the only disorder that hits all factors of executive function.
Then he said adhd people can't do digitspan backwards so e went to try it and I was like 😦
Just tried it and can't even get it right forward. Shit.
What’s a digitspan?
A test for working memory.

I don't have ADHD and my upper limit for digits seems to be around 6.
It took a few tries, but if I memorize the numbers in chunks of 3, then 3, then 2 then it's a lot easier.
I believe 6 or 7 is the average across the whole population
I would be surprised if he said that, because that's blatantly incorrect:
https://www.frontiersin.org/articles/10.3389/fpsyg.2015.00328/full (Table 2, for example).
Schizophrenia, bipolar disorder, and major depressive disorder all produce or are associated with executive function impairments that are more severe than ADHD, and across various forms of EF. ADHD is the only one of those with its specific pattern of attentional and reward-related abnormalities, but broad EF deficits are common across forms of psychopathology.
This is true, and suggests maybe a broader recategorisation is in order.
I’ve heard one expert suggest that while many disorders feature executive dysfunction, ADHD is executive dysfunction.
We've known that this isn't true since 2005:

In addition, plenty of other disorders show worse executive function than ADHD:

If executive dysfunction is your primary issue, that is not indicative of ADHD. ADHD is driven by reward processing dysfunction and slower information processing:
