I can only find opinion articles.
I will say again.
Please cite Trumps medical records.
Failing that please cite your qualifications in psychology and justification to make that call based on your television and never meeting the guy.
It's also a desperate stretch to call dementia a mental illness. More like entropy.
Also google "is the earth flat"
Or
"Is the queen a reptile."
And get back to me.
Don't believe everything you see or read, even if it's on the holy television.
The queen is not a reptile, but Hillary Clinton is. Did you see her eyes?
As for Trump, it could also be ADHS. That would explain, why he can read only short and very simple texts and cannot follow a conversation longer than a few minutes. But if you compare his current behaviour with as he was, say, 10 years ago, you will detect an amount of cognitive erosion
I have no medical qualifications, I use a bone oracle that has turned out to be accurate 85% of the time
Regarding Trump's medical records, as everybody knows, he is the most healthy person who has ever run for president.
