Trump keeps losing his train of thought. Cognitive experts have theories about why

Former President Trump 's disjointed and incoherent verbal habits seem to have increased in his speech in recent years , according to experts in memory, psychology, and linguistics.

In 2017 , a STAT analysis showed Trump ’s speaking style had deteriorated since the 1980s .

While none said they could give a diagnosis without an examination, some said certain shifts in his speaking style are potential indications of cognitive decline.

Since 2020 , since 2020 , Trump has increasingly spoken about the past, with around a 44% increase in past-focused sentences, and is spending very little time talking about the future.

A linguistic metric of analytic thinking shows that Trump ’s levels of complexity have always been unmistakably low, said Pennebaker .

Linguist Mark Liberman noticed that Trump also seems to be speaking more slowly now than compared to seven years ago .

Determining a definitive cause for Trump ’s shifts in language would require in-person tests and interviews.

Analysis is further complicated by Trump 's long-standard unusual communication manner: “You’ve got to keep talking. Never stop. Make up names for your opponent, make fun of your opponent.. promise all kinds of things”.
