President Donald Trump's recent speech for America's 250th birthday celebration was riddled with "significant" signs of possible "neurological decline," according to one licensed pathologist, particularly his numerous slurred mispronunciations of certain words and phrases.
On Wednesday, Trump delivered a speech at the National Mall in Washington, D.C., as part of the "Great American State Fair" event that has been plagued with controversy in recent weeks. The online discourse after the event was dominated by videos that appeared to show crowds leaving midway through his speech, leading to more speculation about the event's lackluster crowd sizes, but according to one medical professional's observations, Trump's own words indicated that something could be seriously wrong with his cognitive health.
Hilary Shae is a licensed speech-language pathologist specializing in concussion recovery, and she has also emerged as a political content creator who offers professional insights into the signs that Trump may be suffering from notable physical and neurological decline. In her latest video from Saturday, she highlighted some of the things that Trump struggled to pronounce throughout the speech, including things like "250th anniversary," "magnificent," "ancient ruins," "Los Angeles" and "horizon."
In some cases, Trump's attempt to pronounce these words trailed off near the end, and in others, he mispronounced the word entirely, often not bothering to double back and try again. As Shae explained, these speech difficulties were "consistent" with certain conditions that can be caused by things like dementia or suffering a stroke, two things that she has previously suggested that Trump might be struggling with, based on his observable symptoms. These flubbed lines, she added, are often referred to as "phonemic paraphasias."
"Phonemic paraphasias are when the motor speech required to coordinate words and syllables together are not coordinated appropriately," she explained. "For example, if I wanted to say 'telephone,' but I accidentally said 'tephelone,' that would be a phonemic paraphasia, because my sounds got mixed up.
She continued: "And that is what's happening a lot of the time with Donald Trump's speech. The coordination for the syllables and order... the more syllables that you have, the higher level motor coordination is required to maintain appropriate speech-sound coordination."
Shae also suggested that this issue could be the result of dysarthria, a condition in which the weakening of muscles required for speech can cause patients to struggle speaking, causing them to sound slurred or slowed down. She argued that this is one of the more recent symptoms that Trump has shown, as is noticeable when he trails off at the ends of certain words, especially ones that are three or more syllables long.
"The fact that there are so many examples of these speech difficulties in one 30-minute speech means that Donald Trump is getting worse," Shae argued. "Whatever is going on, whether it's dementia, whether it's a stroke, whether it's a combination, whether it's congestive heart failure, whether it's whatever it might be, his neurological abilities are declining significantly."
