Long story short: I've been care-giving for someone who is suspected (by three physicians and a neurologist -- also a physician, it would seem ) of having FTD, a.k.a., Pick's Disease.

In all of my searching for info. that may provide insight re: testing that may offer a more definitive answer, the only sources I could find all tend to reference having to wait for an autopsy. Not very promising to see that blaring.

This is the first article that says a MRI may be helpful. With the advance it Dx'ing since 2009, maybe there is more hopeful info., as well, that I've just not come across, yet.

However the Newsbot works: Great! I feel enlightened, especially since I've taken the person for ER attention (when totally disoriented) and never hope to ride in the front of an ambulance again or spend another holiday at ER. A CT was done. And, more recent, a MRI.

I'm most accustomed to looking at CTs, MRIs, X-rays re: the spine, so I don't know exactly what it is that doctors see within the imaging, but it's definitely brain atrophy or degeneration, as they've said.

My heart goes out to everyone who is living through the maze of dementia... and, in whatever form it manifests itself. Not easy to watch another person go through so much, possibly understanding something isn't quite right but not understanding exactly what it is or all that it entails.
