A TikTok video speculating that Russian president Vladimir Putin could have Parkinson’s has gone viral. It was posted by a nurse, who goes by the username Haus of Petty or @musclesandnursing and has since racked up more than two million views. “Nurses and medical professionals, I’m going to show you a video and this is why we should be terrified,” @musclesandnursing said in the video. The clip then shows what they perceive as Putin stumbling slightly on his right leg.

“I’m a nurse I cannot diagnose, but I do know Parkinson’s and a stroke when I see it. Parkinson’s is under the umbrella of dementia,” @musclesandnursing said. Parkinson’s is a neurodegenerative disorder which impacts people’s movement. The symptoms usually begin gradually and tend to impact one side of the body more than the other. While it’s all speculation, he did go on to suggest that Putin “probably had a stroke” based on the “utilization of his right leg” and the slight jerk in his stride.

“If you’ve ever been to a nursing home and you see those two little old biddies just sitting there and they’re like best friends?” he added, speaking more about Parkinson’s. “It’s because their communication style is on par. People with dementia are very good at covering up their dementia.” He went on to say: “If you look at what he’s doing, Vladimir Putin is mentally unstable, and he’s got keys to nukes.”

Speculation, but interesting speculation, nonetheless.
