There will always be people with severe mental health issues that will melt down during a crisis. Bluntly, there's a lot of neurotypical people who will also do the same.

I know of several people on the autism spectrum that I would want to be by my side in a crisis. ADHD is one that's usually great in a crisis, autistic spectrum brethren are going to be good depending on where in the spectrum they land, and neurotypicals are going to be all over the place in terms of helpfulness.

Bluntly, most neurodivergent people are so diversified in their interests that they have a larger breadth of skills due to their underlying conditions, making them really good improvisers.

Other disorders like anxiety or something, or anyone low functioning, is a bit like saying that paraplegic persons are bad at running up a hill, or climbing stairs. The same way you wouldn't ask a wheelchair bound person to climb a mountain.
