Episode notes
All Night Posting Suggests Manic Episode
- Gartner highlights an all-night posting spree as evidence of a manic episode with sleep disruption and impulsive posting.
- He outlines a timeline of rapid posts including Jesus at 9:40pm and a policy announcement after midnight.
Dementia Erodes Reality Testing
- Gartner connects frontotemporal dementia to loss of reality testing, saying Trump now cannot distinguish lies from fantasies.
- He argues this neurological decline makes messianic claims and delusions persistent and not amenable to disproof.
Use Full Neuropsychological Testing Not Just MOCA
- Gartner recommends a full neuropsychological battery rather than a brief screen to evaluate cognitive fitness.
- He notes Walter Reed visits and plural cognitive tests suggest such an extensive workup may already have been done.
