Dr. Tom Pitts appeared on "NBC News Now" Monday to discuss the conversations swirling about a Parkinson's expert from Walter Reed National Military Medical Center, who visited the White House eight times in the last eight months, per the logs released by the White House.

Here was the exchange between Pitts and the NBC anchor:

Anchor: You noticed anything that gives you a red flag as a doctor?

Pitts: Oh yeah. I see him 20 times a day in clinic. It's ironic because he has classic features of neurodegeneration. We're finding difficulties -- and that's not 'Oh, I couldn't find the word' that's from degeneration of the word retrieval area. 

Anchor: He's also overcome stuttering, though. Could that be part of that, too?

Pitts: No, this is not a palatal issue or a speech discrepancy, which is very different ... rigidity, loss of arm swings, standing up lordotically; you notice when he turns, it's kind of end block turning, it's not a quick turn, so that's one of the hallmarks of Parkinson's, is rigidity and bradykinesia, slow movement, and he has that hallmark, especially with the low voice. They said it was a 'cold,' hypophrenia; a small, monotone voice like this, over time, is a hallmark of Parkinsonism. I could've diagnosed him from across the mall. 

NBC later showed some of the symptoms of Parkinson's disease, which included rigidity, tremors, slowed movement, masked face, and soft or low voice. 

They continued the conversation shortly after showing the list:

Anchor: What about the movements? Some people have pointed out the way he walks sometimes; it's not very fast, small steps. Is that something that is common in people who are battling a disease like Parkinson's?

Pitts: Yeah, it's a hallmark. Shuffling gate, we call that, it's little steps, loss of arm swing from the rigidity when we walk, we have a nice cadency, you notice he doesn't really swing his arms, and end block turning; meaning, he kind of pivots around his foot.

Anchor: It's very hard to diagnose Parkinson's, isn't it? 

Pitts: It's one of the easier movement disorders to diagnose, actually. And I'm a Democrat; it's just like, this guy is not a hard case. 

Anchor: But I've had relatives who have gone through issues; neurological issues, and I've heard that sometimes Parkinson's is not very easy to nail. You have to take a lot of tests.

Pitts: ... Once you start manifesting the hallmark motor symptoms: slow movement, rigidity, mask faces, hypophrenea. I mean, if a med student did not pick Parkinson's on the test, they'd be remediated.

Anchor: You're a Democrat, you're a doctor, you sound like you're frustrated with what the White House is saying. Why?

Pitts: Yeah. Well because I'm an American before everything, and I look at it and say: Well, I used to see Russia -- Soviet Union, North Korea -- when they just make outrageous things. You know, like when North Korea can't keep the lights on, they say 'Oh it was some faulty power thing,' I kind of hate that kind of stuff. They had four years -- my own party had four years -- you know, this was a wreck in slow motion, and they had four years to find, out of 350 million Americans, one person that could take the place. and here we are, the day before 'school' trying to do the homework and replace a guy who's got a neurodegenerative disease.
