Drs. Elizabeth Lee Vliet and Jane Orient are finding inconsistencies in a letter written by Hillary Clinton’s doctor that claims the Democrat presidential nominee is recovering from “non-contagious bacterial pneumonia.”

Though neither Vliet nor Orient have personally examined Clinton, they’re giving Breitbart News some insights into a letter written by Dr. Lisa Bardack, the chair of Internal Medicine at CareMount Medical in Mount Kisco, New York, who said Clinton was being treated for “a mild non-contagious bacterial pneumonia” after becoming “overheated” during a 9/11 Memorial event when the nominee appeared to collapse and had to leave abruptly.

Vliet, who specializes in women’s health, and has a background in internal medicine, neuropsychiatry, and neuroendocrinology, observes that Clinton is highly unlikely “to have ‘cleared’ a pneumonia within 90 minutes to suddenly appear for the photo op on the sidewalk, walking like a healthy person.”

She referred to Clinton appearing as she left her daughter Chelsea’s apartment building – to which she was taken after her apparent collapse – stopping to wave to the crowd and even hugging a small child.

“She would have likely looked sicker if she really had pneumonia,” Vliet explains.

Bardack wrote:

On Friday, September 9, she was seen and evaluated in my office. A non-contrast chest CT scan, including a CTA calcium score, was performed. This test allowed for specific imaging of her lungs while also following up on cardiac risk stratification from 2010 given her family history of heart disease. The results of the CT scan revealed a small right middle-lobe pneumonia; her coronary calcium score was again zero. She was treated with antibiotics for pneumonia and advised to rest. This was a mild non-contagious bacterial pneumonia. On Sunday, September 11 at the 9/11 Memorial event, she became overheated and dehydrated and as a result felt dizzy. I examined her immediately upon her return home; she was re-hydrating and recovering nicely. I advised her to stay home and rest for the next several days. Mrs. Clinton has since been evaluated by me several times and continues to improve.

“My overall impression is that Mrs. Clinton has remained healthy and has not developed new medical conditions this year other than a sinus and ear infection and her recently diagnosed pneumonia,” Bardack continued. “She is recovering well with antibiotics and rest. She continues to remain healthy and fit to serve as President of the United States.”

Dr. Jane Orient, who specializes in internal medicine, tells Breitbart News, “’bacterial pneumonia’ covers a very broad field.”

“The type of bacteria is very important for antibiotic choice,” she notes, questioning whether cultures were obtained.

“How can Dr. Bardack say she is not contagious when much of Clinton’s staff is sick?” Orient asks as well.

As Breitbart News reported, a Clinton campaign source told People Magazine, “Everyone’s been sick,” and described “a debilitating bug” that was causing at least six people – including Clinton campaign manager Robby Mook – to fall ill.

To add to the media confusion, Bill Clinton said during an interview that his wife had the flu – rather than pneumonia – but then backtracked on that statement later, Fox News reports.

“The mild pneumonia does not explain months of coughing, nor the reported confusion, strange head movements, episodes of apparent inattention, or sudden falls,” Orient also observes, emphasizing as well that Bardack’s letter “is not the ‘medical record.’”

“The letter is just one person’s very incomplete exam,” she continues. “Not even the basics like vital signs (pulse, respiratory rate, blood pressure, pulse oximetry when acutely ill – though they are there for her previous exam). There’s also no check of standing blood pressure and pulse, though she was said to be dehydrated.”

Vliet also expresses concern about what she calls Clinton’s “movement” problems:

I think her dystonic movements, “freeze” falls, wooden movements (evident in the video of Ground Zero when her team was trying to get her into the car), as well as her lack of usual protective reflexes in multiple falls over several years, her abnormal eye movements, vocalizations, difficulty swallowing/coughing spasms – all strongly suggest a neurodegenerative movement disorder.

“The big issue is that pneumonia is treatable and curable,” notes Vliet. “But a neurodegenerative disorder such as Parkinson’s disease is a terminal illness that before death causes dementia.”
