I know it's a broad umbrella, as not only do many different disabilities exist, but their severity as well.
For the people I am often around, living independently is the most shared goal. That in itself encompasses many things like motor skills, ability to keep routines, assistance for daily tasks, etc.
I realize this may be niche so I welcome adjacent findings as well.
Thank you!
