Hillary Clinton, who’s been plagued by health issues in recent months, apparently has another to deal with now.

A July 21 video posted on YouTube shows Clinton’s head suddenly turning and shaking vigorously for several seconds.

Blogger Jim Hoft of the Gateway Pundit headline it: “Wow!” Did Hillary Clinton Just Suffer a Seizure on Camera?”

“The poor woman is in worse shape than we thought,” he wrote.

In the video, Clinton’s eyes close then open and stare, but she never loses her huge smile.

She says, “You guys have got to try this cold [drink].”

It’s not the first time health issues have arisen.

Last month, the American Mirror reported a coughing fit that broke out as someone else was speaking during an appearance.

WND reported in January, following several of the coughing fits, that her refusal to answer questions about them – or to explain why she wore eyeglasses fitted with Fresnel prisms – raised concerns from several physicians that her campaign was keeping health records hidden.

She had a huge coughing fit during a speech in New York City. Then, in a visit to Las Vegas, she wore thick, black glasses fitted with Fresnel prisms.

At the time, WND asked several physicians if they believed the glasses, which are used to correct double vision, could be related to the concussion she suffered in December 2012 that resulted in a blood clot in her head.

WND also asked whether Clinton’s repeated coughing bouts could be related to her hypothyroid condition for which she is taking Armour Thyroid, as WND previously reported, a natural remedy made from desiccated pig glands, or from her apparently congenital predisposition to form blood clots. To prevent clots, as WND reported, she is taking Coumadin, otherwise known as warfarin, an old but commonly prescribed blood-thinning medication originally developed as a rat poison.

WND also reported the medication Clinton has taken since 1998 to deal with her blood-clotting problems may have side effects such as blurred vision and confusion, both of which she has experienced. And a California physician warned Coumadin could be more life-threatening to her than the possibility of a recurring blood clot.

“It is very hard to draw substantial conclusions from the limited medical information we have on Hillary Clinton,” explained Dr. Todd Lasner, a neurosurgeon at Mount Sinai Medical in Miami.

“We cannot opine with 100 percent certainty, because we do not have all the medical facts,” he said. “Fresnel prisms are typically used to correct double vision, to refract light through the prism so you can see a single image as you are normally used to seeing.

“My first suspicion would be the Fresnel prisms were prescribed for Hillary Clinton because of nerve damage causing double vision resulting from a trauma to her head, possibly from the fall causing the concussion,” Lasner concluded. “But without her medical records, I cannot say for certain.”

Dr. Daniel Kassicieh, D.O., a dual board certified osteopathic neurologist and a leading headache specialist who directs the Florida Headache and Movement Disorder Center in Sarasota, Florida, agreed that the diagnosis of Clinton’s double vision and the prescription of a Fresnel prism lens would require consultation with a medical specialist.

“I saw Hillary Clinton first wearing the eyeglasses with the Fresnel prisms when she testified to Congress on Benghazi in January 2013, and she continued to wear them a while,” Kassicieh told WND at the time. “Then I saw her again this week in Las Vegas wearing those black eyeglasses with the Fresnel prism lenses, and I wondered when her double vision came back, or if it never really went away.”

Kassicieh said he noticed Clinton’s coughing spells seem also to be a persistent and recurring problem.

“I think Hillary’s cough is a separate medical problem from her double vision,” he said. “But it makes me wonder if there isn’t something else going on with her health that we don’t know about.”

Dr. Ronald Hoffman, a New York City physician who hosts the nationally syndicated radio program “Intelligent Medicine,” told WND in a telephone interview then that without the medical records, “we really have no idea what the medical condition causing Hillary Clinton to be wearing eyeglasses fitted with Fresnel prism lenses.”

Hoffman is past president of the nation’s largest organization of complementary and alternative doctors, the American College for Advancement in Medicine, or ACAM. He’s the founder and medical director of the Hoffman Center, specializing in a natural medicine approach that combines nutritional and metabolic medical assessment tools with high-tech innovations in traditional medicine.
