Yoy may be interested in this online seminar coming up.I got an email about it,but don't know how to share the link, so just did a screenshot of the relevant bit. Perhaps you could help Pinkvision?
It's by Donalee Markus, who has done a lot of work with puzzles helping after a TBI. We have the app, Designs for Strong Minds,and I believe the puzzles in there have helped my husband.
I've signed up for it anyway, it's free.
