Two common symptoms of dementia (inability to pronounce longer words correctly or remember simple things in the recent past) both commonly being the first symptoms of moderate-to-severe Alzheimer's dementia onset. 

I've noticed Xiden doing both of these things repeatedly or as Xiden would say, "repeatly".  That old fool forgot the name of one of his cabinet members the day before (after he was introduced a few seconds before). 

Ironic that the 'Crats made so much of the 25th amendment being necessary to deal with DJT's supposed "impairment". heh Most of the nation believes it is reasonable to invoke the 25th now for Xiden 'cause he's gone gone gone. 

XIDEN: (snarling in rage at impetuous person in restaurant with the AUDACITY to ask him a serious question about public policy) HEY!!! (fixed, menacing glare mirrored by two glowering "aids") I'M GETTING SOME ICE CREAM!!! (still glaring hatefully) It's the WEEKEND, man!!  

Touchy, touchy. That's another symptom of dementia onset- frequent, sudden hostility in response to normal behavior (Ex; politely being asked a question) - AKA schizoaffective (psychotic) rage. That's one of the things that make people with moderate/severe Alzheimer's (like Xiden) horribly, lethally dangerous. So much of what they perceive and believe makes them uncontrollably angry/agitated. 

* Secret Service members posted at Xiden residence during the Eightball Obama regime reported that Xiden regularly swam au naturale in his pool while the agents were required to stand by and watch him. Strange, perverted bastard.
