During the campaign she had a few major episodes that were caught on camera. She had the head bobbing episode while talking with reporters(dyskinesia). She spaced out at a campaign rally and needed her SS agent to hit the reset button. Then there was the bizarre "why I am not 50 points ahead" video(face masking). She was stiff as board while waiting for the van to arrive at the 9/11 event(freeze). Towards the end of the campaign, they showed a video clip of her getting off a plane. She had no idea if she was coming. or going.
Since the election she has had several falls and broke her toe and wrist. Now she has a back brace. Something major is going on.
Back at the end of her term as SOS she had some sort of brain injury causing double vision requiring prism glasses and a variety of other symptoms. The other episodes suggest something is wrong. It is also pretty clearly neurological like Parkinsons. Falls can be caused by Parkinsons and perhaps by the meds (dyskinesia). But since there are no other symptoms in my viewing of her speech from a couple of days ago, I would guess the falls are from seizures. The sack of potatoes into the van looked like a seizure.
