The drug's commercial name is Leqembi, and it's drug name is Lecanemab (https://en.wikipedia.org/wiki/Lecanemab).
And la Presidenta is probably on it. The problem with his right hand is likely caused by the intravenous application. And the newly installed signs around the WH are what you do for Alzheimer's patients so they do not get themselves lost. His rage posts at all hours of the night indicates someone who is up all night, another symptom of that drug. The people in his "Dear Leader" cabinet meetings treat him like an Alzheimer's patient because that is what is normally done for an Alzheimer's patient, i.e. bombard him with constant happy talk lest he go bonkers in front of them, or worse, in front of cameras which would cause people to ask his cabinet embarrassing questions such as "Is he nuts or are you?"
The problem with you Maggots is that you refuse to realize what is right in front of you. With la Presidenta, his behavior has always been so stupid that it is sometimes hard to distinguish from mental degeneration. And what happens to the Maggots once Dear Leader goes 'round the twist? Answer: deny he's mentally incapacitated because Project 2025 can still supply him with stupid shit to sign, which is indistinguishable from the stupid shit he would normally come up with. He's just a useful idiot who thinks he's president.
