Multiple medical professionals assert that President Joe Biden should undergo a comprehensive evaluation and testing for Parkinson's disease in order to continue his participation in the election.

Experts have observed that Biden has displayed multiple symptoms associated with Parkinson's disease, such as a slower gait, a minor jerking motion when initiating movement, a lack of facial expression (hypomimia), a fixed gaze with reduced blinking, and a low, hoarse voice (hypophonia), all of which have occurred simultaneously.

“The pathologic elements seem fully aligned,” an unnamed doctor who has treated many Parkinson’s told law professor and blogger Paul Campos.

Dr. Kevin Cannard, a specialist in Parkinson's disease at Walter Reed Medical Center, engaged in a conversation with Dr. Kevin O'Connor, President Biden's personal physician, as well as Dr. John E. Atwood and an anonymous individual.

As stated in the visitor logs, the encounter occurred on January 17 at the White House residence clinic, as reported by the New York Post. This meeting is taking place in response to concerns about President Biden's cognitive well-being, which have arisen after his recent debate with former President Donald Trump.

The meeting's aim, as conjectured by Rep. Ronny Jackson, who has provided medical care to Presidents Obama and Trump, was probably focused on President Biden, considering Dr. O'Connor's main duty for the President's health.

Dr. Cannard is an esteemed authority in the field of neurology, specifically in the area of Parkinson's disease research. He has accumulated nearly twenty years of expertise at Walter Reed Medical Center.

For starters, Dr. Cannard has been a neurology specialist for the White House Medical Unit since 2012. His knowledge has been crucial in dealing with the initial phase of the condition, as emphasized in his recent paper in a prestigious medical magazine.

In the midst of ongoing inquiries over President Biden's mental acuity, Dr. O'Connor, Biden's designated physician, has come under examination, with Rep. Jackson alleging that O'Connor and the First Family have been hiding the President's deteriorating cognitive capabilities.

Jackson's assertions have ignited discussions about a potential "concealment" of the President's state of health.

Kelvin Chou, a distinguished professor of Neurology at the University of Michigan Medical School, expressed apprehensions regarding the neurological health of the two leading contenders. He specifically highlighted Parkinson's disease as the primary issue for President Biden, based on the video clips he has observed.

 "Based on chats with my neurologist and movement disorders colleagues, they all agree as well,” Kelvin went on.

Business Times has reached out to President Joe Biden for comments.
