I’m a former school psychologist. I have had a similar experience. I’m learning to weave and was making some projects that pleased me. Then I went hiking and had a fall. They did brain imaging and that checked out okay, but I definitely had a period of time when I was having problems with weaving. With time, and what patience I could muster, I am now back to where I was and am learning new things. I think psychometric testing is a good idea. It’s a good baseline for the future. I implore you to go to a certified clinical psychologist. The psychologist should do the testing and interpretation. Do not go to a place that uses untrained, uncertified “ technicians”. Don’t assume, ask. You will probably be in the room for three hours or so. Some questions will be too easy and some will be too hard, but most will be doable. That is the nature of psychometric testing. The testing may reveal a learning style or other information that you can use in your quilting. I hope things go well for you in your quilting. It is such a wonderful creative outlet, and the socialization and learning you do is good for your brain. And I too would love to see a picture.
