Overview

• Clinical psychologists John Gartner and Harry Segal say President Donald Trump’s psychomotor performance is deteriorating, pointing to signs they view as consistent with dementia.
• Their latest analysis emphasizes a “wide-based gait” they call a telltale indicator of frontotemporal dementia, describing a semicircular leg swing that affects balance.
• They highlighted red-carpet footage from Trump’s meeting with Vladimir Putin in Alaska, asserting he appeared to weave left and right as he walked to greet the Russian leader.
• Gartner likened the observed veering to failing a DUI walking-line test, while stressing that motor changes appear to be getting “worse and worse” compared with earlier speech-focused concerns.
• Trump has touted a high score on a cognitive test from his April physical, and White House physician Dr. Barbabella wrote that he exhibits excellent cognitive and physical health.
