According to the press surrounding the release of his new book, anyway.

I've often wondered about it. 30 years is a long time to have PD without developing dementia, though i appreciate that age is a big factor and for much of those 30 years he was fairly young by PD standards.
Still, he's done very well and pushed along PD research more than another other individual.
I hope he still has good days.
Here he is today. Does not seem demented:

I agree that he doesnt appear to be suffering from advanced dementia.
He looks pretty good to me, for those in the UK he's on 'Good Morning' (ITV 1)this coming Friday at around 10.00👍
I saw a lot of those click-bait headlines relating to his latest interviews. He's quote was his "short-term memory is shot". he simply could of been referring to brain-fog, another common symptom. it doesn't mean he is suffering from dementia.
Without having read the book difficult to say, but from the article:
"Fox has begun to notice cognitive changes, including memory loss, confusion, delusions and dementia — something he has “rarely contemplated before now, much less spoke of.” He describes looking for his car keys before remembering he can no longer drive; mistaking one of his twin daughters for the other and uttering, “What did you think?” to “the person to my left, who isn’t there.”"
I'd say each of the three examples is pretty classic of early dementia. They dont reflect "brain fog" to me, at least not the type commonly reported in early PD.
He's almost 60 and has had PD for like 30 years. It would hardly be shocking.
Sorry, i didn't read the article you posted. presumed it was the same as the many posted last week. but ya, that does sound like early stage dementia 
Ah yes, understood. Yes i saw that quote also and thought "well it could be worse" and then i saw this more recent article and then thought "so it is worse".
Short term memory loss can be an early form of mild “dementia.” My MIL started that way and now it is quite severe.
It must be difficult having thousands of people discuss wheather you are demented or not. When did that become fair game ? He said that he is having difficulty remembering his lines.
If you read the article i posted, dementia is actually called out, as are specific dementia symptoms that he seems to be suffering.
Its not just him forgetting his lines.
As for people discussing it, he wrote a book and is promoting it, so i suspect he is probably ok with it.
