Donald Trump’s health is back under intense scrutiny after a clinical and forensic psychologist examined a series of the US President’s public appearances. Dr. John Paul Garrison claimed he saw a troubling pattern involving speech and word-finding difficulties, apparent spasms, twitching and moments when Trump appeared tired or overwhelmed. In his analysis, Garrison raised possible neurological explanations, including dementia and Alzheimer’s-type dementia. Trump’s physician, Dr. Sean Barbabella, has previously said the President is in “excellent health” and has “strong cardiac, pulmonary, neurological and overall physical function.” Trump has also repeatedly rejected concerns about cognitive decline.
