Over the weekend, the Drudgereport.com published a Reuters photo that showed presidential candidate Hillary Clinton, 69, being assisted up a flight of stairs by aides in February.
The photo sparked calls from the public for Clinton to open her medical records and prove she is medically fit to run for office.
"I think the public has a right to know," said Dr. Marc Seigel in an interview with Fox News host Sean Hannity. "We're talking in 2008, Sean, I looked over a thousand pages of John McCain's records because of a melanoma he had 10 years ago. What about Hillary?"
Seigel reminded Hannity that it took Clinton 6 months to recover from a severe concussion she suffered when she fell in 2012.
At that time, Clinton was diagnosed with a brain clot. Her doctor prescribed a lifetime of blood thinners to prevent more clots from randomly forming.
"Guess what if she falls and hits her head? She'll get [another] blood-clot," said Seigel.
"I want to know what her neurological records show," he said.
"The picture going up the stairs speaks a million words," said Dr. David Samadi.
"What we know today is she's on thyroid medication, she suffers from hypothyroid, low thyroid, that can cause fatigue and gaining weight and all of that," he added.
"I think a traumatic brain injury with symptoms down the road is very, very likely here especially since she had a blood-clot on her brain, Dr. Seigel said. "As David mentioned that could lead to a seizure problem. Someone is carrying a [diazepam] pen that you'd use in case of a seizure, a Valium pen, that makes me wonder about that.".
Pharmaceutical executive Martin Shkreli says Clinton's tremors and unstable gait (unsteady walking) are signs of Parkinson’s disease.
Shkreli said her seizure-like facial movements are signs of a form of Parkinson’s-induced dyskinesia.
