I am one of those that was really saved in a way by finding out that Lupus people have brain fog, and my memory loss was due to Lupus, not alzheimers. I was terrified to tell my doctors about this, until I found this forum. I could see myself in a nursing home, with complete memory loss, and powerless.
Now I tell my doctor about it.
dermomyacitis I am not familiar with either. Hopefully someone else will be.
