I had heard that. But in the last couple of weeks I had read that the MRI process had progressed.
It’s been a few years since I was on “the front lines” of that. Most of the cases I dealt with were very early onset (55 yr old) or elderly vascular, run of the mill, dementia.
I happily stand corrected.
It’d be great if there were an actual physical test of any sort for dementias.
The cognitive behavioral tests are pretty good.
I’ve seen Alzheimer’s close up, relatively early onset with slow but steady progression over a couple decades.
