NEW YORK – A new doctor specializing in internal medicine is convinced Hillary Clinton is suffering from epilepsy and that a brain seizure could well be triggered in Monday night’s debate.

Amid the mounting evidence Hillary Clinton is suffering from a serious neurological disease, a physician in Ann Arbor, Michigan, has presented WND with her expert analysis of recent videos of Clinton, concluding she has recently exhibited strong symptoms of both Petit mall and Grand mal brain seizures.

“I specialize in internal medicine and can assure you that Hillary is having Petit mall seizures and you can see it clearly on the video of Hillary freezing during her Las Vegas speech in August, if you know what you are looking for,” Paulette Metoyer, MD, explained to WND in an email and a subsequent telephone interview. “I’m concerned Clinton could easily experience another seizure during Monday’s presidential debate with Donald Trump.”

Her concern over Monday’s debate is that the lights required for the television broadcast or any unusual audience movements might trigger in Clinton another epileptic seizure that could be recognized by competent medical specialists watching the broadcast.

As evidence of her medical concerns that Clinton was suffering petit mal seizures, known as “absence seizures,” Dr. Metoyer referenced the speech Clinton gave at a campaign rally in Las Vegas, Nevada, on Aug. 5, when she appeared visibly shaken as animal-rights activists against Trump began yelling near her rally stage.

Watch video of Clinton's startled reaction at Las Vegas rally:

The video shows Clinton frozen until one of her aides, apparently a Secret Service agent, approaches her, puts her arms around her, and says in her ear, loud enough to be heard on the video recording, “You’re OK. Keep talking. We’ll handle it. We’re not going anywhere. Keep talking.”

Clinton snapped out of the freeze, repeating, “OK, here we are. OK, we’ll keep talking.”

“Petit Mal seizures are easily missed by people who have not seen them, including a lot of doctors,” Dr. Metoyer explained. “But my deceased brother had Petit Mal seizures, and I have personally seen a lot of them.”

Dr. Metoyer said that’s what she sees in the Clinton video from the Aug. 5 rally in Las Vegas.

“The opening scene shows a typical Petit Mal seizure characterized by repetitive lip smacking and a blank stare followed by a state of confusion,” she said. “You may have to play it twice to recognize it, especially if you have never seen it before.”

Dr. Metoyer continued referencing the aide, the apparent Secret Service agent, who approaches Clinton during her apparent freeze.

“Notice her ‘secret doctor,’ the one who carries what appears to be a Valium pen typically used as a medical agent used for seizures,” she said. “This aide says to her to ‘keep talking. Clinton does as instructed, and then mindlessly repeats what aide says.”

Dr. Metoyer disagreed with the analysis that Clinton is suffering from Parkinson’s disease – a theory WND reported has been advanced by Theodore “Ted” Noel, a retired anesthesiologist in Orlando, Florida, with 36 years experience and a background in critical care.

“My theory, as a doctor who is trained to diagnose and treat (although I would not do so) such a condition, is that Hillary suffered a brain injury following her concussion that was complicated by a thrombosis in the venous system of her brain," Dr. Metoyer told WND.

On Feb. 19, WND reported that Clinton was observed at the Benghazi committee hearings and again at a photo opportunity in Las Vegas, wearing special thick, black eyeglasses fitted with Fresnel prism lenses that Dr. Todd Lasner, a neurosurgeon at Mount Sinai Medical in Miami, speculated were prescribed to correct double vision resulting from the fall Clinton suffered that caused a concussion and a Cerebral Venous Sinus Thrombosis, CVST, a blood clot in the head between the skull and the brain in the sinus behind the ear.

Dr. Metoyer expressed her concern to WND that the cobalt blue lens sunglasses Clinton was observed wearing at the 9/11-anniversary ceremony in New York may have been specialized Zeiss Z1 cobalt blue lenses manufactured by Zeiss to reduce photosensitivity in epileptic patients.

“An examination by competent independent neurosurgeons should be able to determine if Clinton developed petit mal seizures, or more accurately partial complex seizures, as a result of that injury,” Dr. Metoyer stressed. “This type of seizure activity occurs hundreds of time a day. It usually occurs in children, who tend to ‘outgrow’ it in adolescence.”

She continued: “When petit mal seizures de novo in adults, it is a different story and can be the result of head trauma or tumors in the brain, specifically the temporal lobe which is the site of the lip smacking. If it occurs it may be accompanied by less frequent grand mal seizures, medically recognized as generalized seizures.”

Dr. Metoyer also referenced Clinton’s collapse episode of being helped into a black security SUV after being escorted hurriedly from the New York City 9/11-anniversary ceremony, apparently suffering a health emergency.

Watch a slow-motion video of Hillary Clinton appearing to faint:

“The clincher is that grand mal seizures are of three types – tonic-clonic seizures marked by muscle contraction alternating with release), tonic seizures marked by continuous muscle contraction, or atonic seizures marked by no contraction of muscle,” she noted.

“Looking at the video of Hillary passing out when getting into the van I suspect that she may have had a grand seizure of either the tonic variety, that would cause stiffness and writing backward, or atonic, which would cause her to lose postural tone and just drop,” Dr. Metoyer continued, noting that she does not believe Clinton lost consciousness in the 9/11 health emergency.

“The event in front of the van on 9/11, I believe, was a generalized seizure that is not an uncommon occurrence in an adult with post-traumatic seizure disorder,” she said in conclusion.

More than a dozen prominent doctors have sounded off on concerns about Clinton’s health and how it might affect her presidency or how she might be impacted by the rigors and stresses of a rough-and-tumble campaign.
