Is Trump's state of mind caused by - a mental condition - prescription drug abuse - a blunt force brain injury?

It is probably a bit of all 3 but I think mostly it is because of a blunt force brain injure. In the Eptein files it was said that once Trump was so busy eye balling young girls in a pool he walked into a glass door so hard it left his face impression on the door - which might of seriously damaged his frontal lobe.
Not sure about this part but maybe the reason doctors can't tell Trump has a brain injure is because Trump has a really really fat head so the machines can't detect it. Cheers and happy weekend!
