There is actually some good evidence for this. Balance and motor control issues (two-handed water drinking, weird stance, the “very steep” ramp thing, later covering the ramp to navy ship), body jerking, slurred speech, lack of impulse control and empathy, etc.

The surprise Walter Reed visit was questionable, and the fact that he was administered a cognitive test only given to those with suspected dementia—then bragged about his results and claimed it was a difficult test—only add fuel to the speculation.

EDIT: Not claiming authority here or that others should conclude what I have, especially since I don’t have the time to reference all the things that convinced me.
