Re: cognitive impairment with amnestic component
Not sure about the MRI. I had my first 10 years ago and my 2nd is schedule on Friday. My understanding is that some stuff (like MS) will show up, but other stuff (like Lupus) will not.
However, your symptoms are very familiar. I've had some very severe cognitive/memory issues for the past few years and I managed to cope for 28+ years before that.
I also just had a sleep study done. I occasionally have some nights where I seem to sleep fine, but then it's like I didn't sleep at all. Fortunately, the sleep study finally caught it, so I'm looking forward to what the sleep doc has to say. I suspect it's part of the problem, but not all of it. (I'll take anything).
