Severe brain fog with possible MCTD

My spouse has a neurological disorder (Parkinson's) and many of the things you describe are related to this disease. I am not suggesting that is what you have in any way, I am mentioning it to say that your symptoms do sound like they could be neurological in origin. Sometimes something simple like a B12 deficiency can cause brain fog as well. Were the falls caused by a problem with balance, or more from tripping caused by foot dropping?

Thanks for sharing, and I hope your spouse is doing alright. As for me, I honestly don’t know why I fell. The first time, there was no warning. I just suddenly collapsed. During the second fall, my daughter saw me from a distance and told me I didn’t react at all, like I had no reflexes. She even said it looked as if I just accepted that I was going to fall. My rheumatologist suggested I see a neurologist because he suspects it might be an absence seizure. It’s the first time I’ve heard of that, so I’m feeling anxious but also hoping to learn more about it tomorrow when I meet with the neuro.
