Read through the wikipedia page[0] on how it's not recognized by most medical associations.
> a specialist in investigating deaths in custody, describes excited delirium as "a boutique kind of diagnosis created, unfortunately, by many of my forensic pathology colleagues specifically for persons dying when being restrained by law enforcement."
Or a deeper Reuters investigation[1] on how closely the diagnosis and acceptance of the "condition" is tied to police and taser manufacturers, Axon specifically. Cmd+F'ing "Mash" will jump you to the parts where they're paying the medical examiner who also happens to diagnose these deaths as exited delirium.
