maladie de pick
I ran into a hunting buddy yesterday at the Felletin market--he mentioned that there's some chatter in France suggesting that Trump has the "maladie de Pick"...I'd not heard of it, so I googled a bit. It's a variant of Alzheimer's disease (and first described by a Czech psychiatrist named Pick). If you're interested, you can check it out, for instance on Wikipedia. It's quite an accurate description of Trump's behavior.
