>>510553237 (OP)That's heart disease. Happened to my dad. He had to have stint put into his heart valve.
Then 2 months after surgery he went loopy as fuck, quite insane, mom was at her wits end.
It happens because of brain swelling after anesthesia.
It wore off he's normal now but it was crazy there for awhile. He was obsessed with everything in the world being a circle and said he was god. And he kept rearranging the books on the book shelf and everything in the garage non stop.
