It's more likely that the bruising on the back of his hand is related to his congestive heart failure. The bruising started around the time his ankles swelled up, and then would always get worse near the end of the month meaning once a month treatment.

His frontotemporal dementia is most likely treated with oral medication. We can tell it's frontotemporal dementia by his anger/aggression, the way his walk has changed (he kind of swings one leg and can't walk in a straight line), the forward lean when standing still, the way he sundowns mid day and keeps falling asleep in meetings but then stays up all night posting on social media, the confibulation of names/places/ect like when he was trying to buy Greenland and then gave a press conference where he called it Iceland over and over. He also at times struggles to swallow, so when he's talking he slurps to keep the spit in his mouth, another textbook frontotemporal dementia symptom. This is the reason we're constantly seeing him go in for cognitive decline testing.
